Octal Bus Transceivers (with 3-state outputs) Description 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 transfe | HITACHIHitachi Semiconductor 日立日立公司 | |||
