DESCRIPTION
The M54/74HCT125/126 are high speed CMOS
QUAD BUS BUFFER (3-STATE) FABRICATED IN
SILICON GATE C2MOS technology. They have the
same high speed performance of LSTTL combined
with true CMOS low power consumption. These de-
vices require the same 3-STATE control input G to
be taken high to make the output go into the high im-
pedance state.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 sys-
tems with TTL and NMOS components. They are
also plug in replacements for LSTTL devices giving
a reduction of power consumption. All inputs are
equipped with protection circuits against static dis-
charge and transient excess voltage.
