GENERAL DESCRIPTION
The PALLV22V10 is an advanced PAL device built with low-voltage, high-speed, electrically-
erasable CMOS technology.
The PALLV22V10Z provides low voltage and zero standby power. At 30 A maximum standby
current, the PALLV22V10Z allows battery powered operation for an extended period.
The PALLV22V10 device implements the familiar Boolean logic transfer function, the sum of
products. The PAL device is a programmable AND array driving a xed OR array. The AND array
is programmed to create custom product terms, while the OR array sums selected terms at the
outputs.
The product terms are connected to the xed OR array with a varied distribution from 8 to 16
across the outputs (see Block Diagram). The OR sum of the products feeds the output macrocell.
Each macrocell can be programmed as registered or combinatorial, and active high or active low.
The output conguration is determined by two bits controlling two multiplexers in each macrocell.
