HD74HC643, HD74HC640 Datasheet - Renesas

HD74HC643 Octal Bus Transceivers

Each device has an active enable G and a direction control input, DIR. When DIR is high, data flows from the A inputs to the B outputs. When DIR is low, data flows from the B inputs to the A outputs. The HD74HC640 transfers inverted data from one bus to other and the HD74HC643 transfers inverted dat.

HD74HC643 Features

* High Speed Operation: tpd = 12 ns typ (CL = 50 pF)
