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.
This integrated circuit 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.
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.
