DESCRIPTION

The M54/74HCT240, HCT241 and HCT244 are

high speed CMOS OCTAL BUS BUFFERs

fabricated in silicon gate C²MOS technology.

They have the same high speed performance of

LSTTL combined with true CMOS low power

consumption. The designer has a choise of select

combination of inverting and non-inverting outputs,

symmetrical G (active low output control) input, and

complementary G and G inputs. Each control input

governs four BUS BUFFERs.

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.

These devices are designed to be used with 3 state

memory address drivers, etc.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.

This integrated circuit has input and output
