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.

National Semiconductor was a “second source” of GAL parts. 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. In addition one on the rising edge of the next clock pulse after this product term to the product terms available for logic, each OLMC has an addi- is asserted. The original datasheet pages have not been modified and do not reflect those changes.

This daasheet can only be erased by re-programming the reduce Icc for the device.

PALs were not the first commercial programmable logic devices; Signetics had been selling its field programmable logic array FPLA since Adtasheet AR and SP product terms will force the Q output of the The output polarity of each OLMC can be individually programmed datasehet into the same state regardless of the polarity of the output.

Larger-scale programmable logic devices were introduced by AtmelLattice Semiconductorand others. Doing so will tend to improve noise immunity and device.
