inputs.

Features

■ TTL input compatible

MM74HCT devices are intended to interface between TTL

and NMOS components and standard CMOS devices.

These parts are also plug-in replacements for LS-TTL

devices and can be used to reduce power consumption in

existing designs.

■ Typical propagation delay: 12 ns

■ 3-STATE outputs for connection to system buses

■ Low quiescent current: 80 µA

■ Output current: 6 mA (min.)
