The PALLV16V8 is an advanced PAL device built with low-voltage, high-speed, electrically-erasable CMOS technology. It is functionally compatible with all 20-pin GAL devices. The macrocells provide a universal device architecture. The PALLV16V8 will directly replace the PAL16R8, with the exception of the PAL16C1.
The PALLV16V8Z provides zero standby power and high speed. At 30-uA maximum standby current, the PALLV16V8Z allows battery powered operation for an extended period.
The PALLV16V8 utilizes the familiar sum-of-products (AND/OR) architecture that allows users to implement complex logic functions easily and efficiently. Multiple levels of combinatorial logic can always be reduced to sum-of-products form, taking advantage of the very wide input gates available in PAL devices. The equations are programmed into the device through floating-gate cells in the AND logic array that can be erased electrically.
The fixed OR array allows up to eight data product terms per output for logic functions. The sum of these products feeds the output macrocell. Each macrocell can be programmed as registered or combinatorial with an active-high or active-low output. The output configuration is determined by two global bits and one local bit controlling four multiplexers in each macrocell.

The PALLV16V8 is a low-voltage, EE CMOS version of the PALCE16V8.
The PALIV16V8Z is a low-voltage, EE CMOS version of the PALCE16V8. In addition, the PALLV16V8Z has zero standby power and an unused product term disable feature for reduced power consumption.
The PALLV16V8 is a universal PAL device. It has eight independently configurable macrocells
(MCo-MC). Each macrocell can be configured as registered output, combinatorial output, combinatorial I/O or dedicated input. The programming matrix implements a programmable AND logic array, which drives a fixed OR logic array. Buffers for device inputs have complementary outputs to provide user-programmable input signal polarity. Pins 1 and 11 serve either as array inputs or as clock (CLK) and output enable(OE), respectively, for all flip-flops.
Unused input pins should be tied directly to Vcc or GND. Product terms with all bits unprogrammed(disconnected) assume the logical HIGH state and product terms with both true and complement of any input signal connected assume a logical LOW state.
The programmable functions on the PALLV16V8 are automatically configured from the user's design specification. The design specification is processed by development software to verify the design and create a programming file. This file, once downloaded to a programmer, configures the device according to the user's desired function.

The user is given two design options with the PALLV16V8. First, it can be programmed as astandard PAL device from the PAL16R8 and PAL10H8 series. The PAL programmer manufacturer will supply device codes for the standard PAL device architectures to be used with the PALLV16V8.
The programmer will program the PALLV16V8 in the corresponding architecture. This allows the user to use existing standard PAL device JEDEC files without making any changes to them.
Alternatively, the device can be programmed as a PALLV16V8. Here the user must use the PALLV16V8 device code. This option allows full utilization of the macrocell.
