DESCRIPTION
The M54/74HCT27 is a high speed CMOS TRIPLE
3-INPUT NOR GATE fabricated in silicon gate
C2MOS technology.
It has the same high speed performance of LSTTL
combined with true CMOS low power consumption.
The internal circuit is composed of 3 stages including buffered output, which gives high noise immunity
and a stable output. All inputs are equipped with protection circuits against static discharge and transient
excess voltage. 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.

(*) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load.
(Refer to Test Circuit). Average operting current can be obtained by the following equation. ICC(opr) = CPD •VCC •fIN + ICC/3 (per Gate)
