Overview
• Bidirectional Bus Transceivers in High-Density 24-Pin Packages • Inputs Are TTL-Voltage Compatible • Flow-Through Architecture to Optimize PCB Layout • Center-Pin VCC and GND Configurations to Minimize High-Speed Switching Noise t• EPIC (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.
