Description

General part information

74ALS688 Series

These identity comparators perform comparisons on two 8-bit binary or BCD words and provide P = Q\ outputs. These devices have totem-pole outputs.

The SN54ALS688 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ALS688 is characterized for operation from 0°C to 70°C.

These identity comparators perform comparisons on two 8-bit binary or BCD words and provide P = Q\ outputs. These devices have totem-pole outputs.
