GENERAL DESCRIPTION
The PALCE29MA16 is a high-speed, EE CMOS Pro-
grammable Array Logic (PAL) device designed for gen-
eral logic replacement in TTL or CMOS digital systems.
It offers high speed, low power consumption, high
programming yield, fast programming, and excellent
reliability. PAL devices combine the flexibility of custom
logic with the off-the-shelf availability of standard
products, providing major advantages over other
