PLC18V8Z - NXP

PLC18V8Z Zero standby power CMOS versatile PAL devices

The PLC18V8Z is a universal PAL® device featuring high performance and virtually zero-standby power for power sensitive applications. They are reliable, user-configurable substitutes for discrete TTL/CMOS logic. While compatible with TTL and HCT logic, the PLC18V8Z can also replace HC logic over the VCC range of 4.5 to 5.5V. The PLC18V8Z is a two-level logic.

Features

an “Output Macro Cell” which can be individually configured as a dedicated input, a combinatorial output, or a registered output with internal feedback. As a result, the PLC18V8Z is capable of emulating all common 20-pin PAL devices to reduce documentation, inventory, and manufacturing costs. A power-up reset function and a Register Preload function have been incorporated in the PLC18V8Z architecture to facilitate state machine design and testing. With a standby current of less than 100µA and active power consumption of 1.5mA/MHz, the PLC18V8Z is ideally suited for power sensitive applications.
