1 / 5 page 54ACT11640, 74ACT11640 OCTAL BUS TRANSCEIVERS WITH 3STATE OUTPUTS SCAS027A − D2957, JULY 1987 − REVISED APRIL 1993 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77001 Copyright 1993, Texas Instruments Incorporated 2−1 • Bidirectional Bus Transceivers in High-Density 24-Pin Packages • 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, Ceramic Chip Carriers, and Standard Plastic and Ceramic 300-mil DIPs description These octal bus transceivers are designed for asynchronous two-way communication between data buses. These devices transmit 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 is used to disable the device so the buses are effectively isolated. The 54ACT11640 is characterized for operation over the full military temperature range of − 55 °C to 125 °C. The 74ACT11640 is characterized for operation from − 40 °C to 85°C.
