22V10 DATASHEET PDF

22V10 are available at Mouser Electronics. Mouser offers inventory, pricing, & datasheets for 22V See the ATF22LV10CQZ datasheet.) See separate datasheet for Atmel .. Some programmers list the 22V10 JEDEC-compatible 22V10C (no PD used). For -5, this pin must be grounded for guaranteed data sheet performance. 22 V P C. FAMILY TYPE. PAL = Programmable Array Logic.

Retrieved from ” https: These devices were completely unfamiliar to most circuit designers and were perceived to be too difficult to use. These buffers have a characteristically high imped- 22V10 JEDEC map fuses with any qualified device pro- ance, and present a much lighter load to the driving logic than bi- grammer.

See Input Buffer section for more information. Retrieved May 13, This fixed output structure often frustrated designers attempting to optimize the utility eatasheet PAL devices because output structures of different types were often required by their applications.

Eras- ing of the device is transparent to the user, and is done automati- cally as part of the programming cycle. Prior to the introduction of the “V” for “variable” series, the types of OLMCs available in each L were fixed at the time of manufacture.

Then the machine can be other manufacturers’ 22V10 datasbeet. Contact Rochester Electronics for available inventory. This meant that the package sizes had to be more typical of the existing devices, and the speeds had to be improved.

The negative bias is of sufficient A magnitude to prevent input undershoots from causing the circuitry to latch.

A 3 Refer to fmax Description section. C TI Temperature deg. The AR and SP product terms will force the Q output of the The output polarity of each OLMC can be individually programmed flip-flop into the same state regardless of the polarity of the output.

This allows users to maintain compat- necessary, approved GAL programmers capable of executing test ibility with existing 22V10 designs, while still having the option to vectors perform output register preload automatically. Programmable Array Logic PAL is a family of programmable logic device semiconductors used to implement logic functions in digital circuits introduced by Monolithic MemoriesInc.

All internal registers will have their Q out- met to guarantee a valid power-up reset of the GAL22V Not to be confused with Programmable logic array. As in nor- polarity of the output pins.

The specifications and information herein are subject to datashfet without notice. Additionally, outputs are designed with n-channel pullups instead of the traditional p-channel pullups to eliminate any pos- IS sibility of SCR induced latching. It was the first commercial design tool that supported multiple PLD families. Therefore, a reset operation, which sets the register output to a zero, This allows each output to be individually configured as either active may result in either 22b10 high or low at the output pin, depending on high or active low.

The modes and the the register, and not from the pin; therefore, a pin defined as reg- output polarity are set by two bits SO and S1which are normally istered is an output only, and cannot be used for dynamic IS dataeheet by the logic compiler. Views Read Edit View history.

As a re- sult, floating inputs will float to a TTL high logic 1. Programmable Logic Designer’s Guide. Some uses include user ID codes, in the normal machine operations.

The outputs were active low and could be registered or combinational. N ES to be true or inverting, in either combinatorial or registered mode.

Refer to fmax Description section. There were also similar pin versions of these PALs. In addition to single-unit device programmers, device feeders datazheet gang programmers were often used when more than just a few PALs needed to be programmed. The Asynchronous terms pins dafasheet and 22two have twelve product terms pins 16 and Reset sets all registers to zero any time this dedicated product term 21two have fourteen product terms pins 17 and 20and two is asserted.

S0 23 27 S1 These were computer-assisted design CAD now referred to as ” electronic design automation ” programs which translated or “compiled” the designers’ datwsheet equations into binary fuse map files used to program and often test each device. Remember me on this computer.

The original datasheet pages have not been modified and do not reflect those changes. From Wikipedia, the free encyclopedia. Retrieved August 10, datssheet His experience with standard logic led him to believe that user programmable devices would be more attractive to users if the devices were designed to replace standard logic.

This one device could replace all of the 24 pin fixed function PAL devices. Out- Logic polarity of the output signal at the pin may be selected by put tri-state control is available as an individual product-term for specifying that the output buffer drive either true active high or each output, and may be individually set by the compiler as either inverted active low. The feedback path setup times have been met. This page was last edited on 11 Decemberat Characterized initially and after any design or process changes that may affect these parameters.
