Description

The M54/74HCT688 utilizes silicon gate C2MOS technology to achieve operating speeds equivalent to LSTTL devices. Along with the low power dissipation and high noise immunity of standard C2MOS integrated circuit, it possesses the driving capability of 10 LSTTL load. The M54/74HCT688 compares bit for bit two 8-bit words applied on inputs P0 - P7 and inputs Q0 - Q7 and indicates whether or not they are equal. A single active low enable is provided to facilitate cascading several packages to enable comparison of words greater than 8 bits.

This integrated circuit M54/74HCT688  has input and output characteristics that are fully compatible with 54/74 LSTTL logic families. M54/74HCT devices are designed to directly interface HSC2MOS systems with TTL and NMOS components. They are also plug in replacements for LSTTL devices giving a reduction of power consumption.

All inputs of M54/74HCT688  are equipped with protection circuit against static discharge and transient excess voltage.
