Overview
D Members of the Texas Instruments Widebus ™ Family D Inputs Are TTL-Voltage Compatible D 3-State Outputs Drive Bus Lines Directly D Flow-Through Architecture Optimizes PCB Layout D Distributed VCC and GND Pin Configuration Minimizes High-Speed Switching Noise D EPIC™ (Enhanced-Performance Implanted CMOS) 1-µm Process D 500-mA Typical Latch-Up Immunity at 125°C D Package Options Include Shrink Plastic Small-Outline 300-mil (DL) Packages Using 25-mil Center-to-Center Pin Spacings and 380-mil Fine-Pitch Ceramic Flat (WD) Packages Using 25-mil Center-to-Center Pin Spacings description The ’ACT16861 are noninverting 20-bit transceivers designed for asynchronous communication between data buses.
The control-function implementation minimizes external timing requirements.
The ’ACT16861 can be used as two 10-bit transceivers or one 20-bit transceiver.
They allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending upon the logic level at the output-enable (OEAB or OEBA) inputs.
The output-enable inputs can be used to disable the device so that the buses are effectively isolated.
