1 / 6 page 74ACT11643 OCTAL BUS TRANSCEIVER WITH 3STATE OUTPUTS SCAS051A − D2957, JULY 1987 − REVISED APRIL 1993 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 Copyright 1993, Texas Instruments Incorporated 1 • Bidirectional Bus Transceiver in High-Density 24-Pin Package • Inputs Are TTL-Voltage Compatible • Flow-Through Architecture to Optimize PCB Layout • Center-Pin V CC and GND Configurations to Minimize High-Speed Switching Noise • EPICt (Enhanced-Performance Implanted CMOS) 1- mm Process • 500-mA Typical Latch-Up Immunity at 125 °C • Package Options Include Plastic Small- Outline Packages and Standard Plastic 300-mil DIPs description This octal bus transceiver is designed for asynchronous two-way communication between data buses. This device transmits data from the A bus to the B bus or from the B bus to the A bus depending upon the level at the direction control (DIR) input. The enable input G can be used to disable the device so the buses are effectively isolated. The 74ACT11643 is characterized for operation from − 40 °C to 85°C.
