Overview
SN54ABT16863, SN74ABT16863 18-BIT BUS TRANSCEIVERS WITH 3-STATE OUTPUTS SCBS225C – JUNE 1992 – REVISED MAY 1997 D Members of the Texas Instruments Widebus ™ Family D State-of-the-Art EPIC-ΙΙB™ BiCMOS Design Significantly Reduces Power Dissipation D Latch-Up Performance Exceeds 500 mA Per JEDEC Standard JESD-17 D Typical VOLP (Output Ground Bounce) < 1 V at VCC = 5 V, TA = 25°C D High-Impedance State During Power Up and Power Down D Distributed VCC and GND Pin Configuration Minimizes High-Speed Switching Noise D Flow-Through Architecture Optimizes PCB Layout D High-Drive Outputs (–32-mA IOH, 64-mA IOL) D Package Options Include Plastic 300-mil Shrink Small-Outline (DL) Package and 380-mil Fine-Pitch Ceramic Flat (WD) Package Using 25-mil Center-to-Center Spacings description The ’ABT16863 are 18-bit noninverting transceivers designed for asynchronous communication between data buses.
The control-function implementation minimizes external timing requirements.
The ’ABT16863 can be used as two 9-bit transceivers or one 18-bit transceiver.
They allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the output-enable (OEAB or OEBA) inputs.

1 V, the device is in the high-impedance state during power up or power down.
However, to ensure the high-impedance state above 2.
1 V, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
