TC74HC688AP/AF

TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic

TC74HC688AP,TC74HC688AF

8-Bit Equality Comparator

The TC74HC688A is a high speed CMOS 8-BIT EQUALITY

COMPARATOR fabricated with silicon gate C²MOS technology.

It achieves the high speed operation similar to equivalent

LSTTL while maintaining the CMOS low power dissipation.

The TC74HC688A compares two 8-bit binary or BCD words

applied inputs P0~P7, and inputs Q0~Q7, and indicates whether

or not they are equal.

TC74HC688AP

A signal active low enable is provided to facilitate cascading of

several packages to compare of words greater than 8 bits.

All inputs are equipped with protection circuits against static

discharge or transient excess voltage.
