DESCRIPTION
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.
