DESCRIPTION
The M74HCT27 is an high speed CMOS TRIPLE
3-INPUT NOR GATE fabricated with silicon gate
C MOS technology.
The M74HCT27 is designed to directly interface
HSC MOS systems with TTL and NMOS
components.

The internal circuit is composed of 3 stages
including buffer output, which enables high noise
immunity and stable output.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.

1) C is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without
PD
load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. I
= C x V x f + I /3 (per gate)
