HD74HCT643

Octal Bus Transceivers (with 3-state outputs)

HD74HCT643 Features

* LSTTL Output Logic Level Compatibility as well as CMOS Output Compatibility High Speed Operation: tpd (A to B) = 14.5 ns typ (CL = 50 pF) High Output Current: Fanout of 15 LSTTL Loads Wide Operating Voltage: VCC = 4.5 to 5.5 V Low Input Cur

HD74HCT643 General Description

Both the HD74HCT640 and the HD74HCT643 have one active low enable input (G ), and a direction control (DIR). When the DIR input is high, data flows from the A inputs to the B outputs. When DIR is low, data flows from B to A. The HD74HCT640 transfers inverted data from one bus to the other. The HD74H.
