DESCRIPTION
The M54/74HCT240, HCT241 and HCT244 are
high
speed
CMOS
OCTAL
fabricated in silicon gate C
2
MOS 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 ofinverting and non-inverting outputs,
symmetrical G (active lowoutput control) input, and
complementary G and G inputs. Each control input
governs four BUS BUFFERs.
This integrated
circuit has input and output
BUS
BUFFERs
characteristics that are fully compatible with 54/74
LSTTL logic families. M54/74HCT devices are
designed to directly interface HSC
2
MOS 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 3state
memory address drivers, etc.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
