DESCRIPTION
All inputs are equipped with protection circuits against static discharge or transient excess voltage. This integrated circuit has input and output characteristic that are fully compatible with 54/74 LSTTL logic families. M54HCT/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.
