HD74HCT243P 数据手册

HD74HCT242/HD74HCT243

Quad. Bus Transceivers (with 3-state outputs)

Description

The HD74HCT242 is an inverting buffer and the HD74HCT243 is a noninverting buffer. Each device has

one active high enable (GBA), and one active low enable (GAB). GBA enables the A outputs and GAB

enables the B outputs.

The device does not have schmitt trigger inputs.

Features

•

LSTTL Output Logic Level Compatibility as well as CMOS Output Compatibility

High Speed Operation: t_pd(A to Y) = 9.5 ns typ (C_L= 50 pF)

High Output Current: Fanout of 15 LSTTL Loads

Wide Operating Voltage: V_CC= 4.5 to 5.5 V

Low Input Current: 1 µA max

Low Quiescent Supply Current: I_CC(static) = 4 µA max (Ta = 25°C)
