DGG OR DL PACKAGE (TOP VIEW) SN54ABT16540, SN74ABT16540 16BIT BUFFERS/DRIVERS WITH 3STATE OUTPUTS SCBS208A − FEBRUARY 1991 − REVISED JULY 1994 Copyright 1994, Texas Instruments Incorporated 3−1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251−1443 • Members of the Texas Instruments Widebus Family • State-of-the-Art EPIC-ΙΙB BiCMOS Design Significantly Reduces Power Dissipation • Latch-Up Performance Exceeds 500 mA Per JEDEC Standard JESD-17 • Typical V OLP (Output Ground Bounce) < 1 V at VCC = 5 V, TA = 25°C • Distributed V CC and GND Pin Configuration Minimizes High-Speed Switching Noise • Flow-Through Architecture Optimizes PCB Layout • High-Drive Outputs (−32-mA I OH, 64-mA IOL) • Package Options Include Plastic 300-mil Shrink Small-Outline (DL) and Thin Shrink Small-Outline (DGG) Packages and 380-mil Fine-Pitch Ceramic Flat (WD) Package Using 25-mil Center-to-Center Spacings description These 16-bit buffers and bus drivers provide a high-performance bus interface for wide data paths. The 3-state control gate is a 2-input AND gate with active-low inputs so that if either output-enable (OE1 or OE2) input is high, all corresponding outputs are in the high-impedance state. To ensure the high-impedance state during power up or power down, 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. The SN74ABT16540 is available in TI’s shrink small-outline package (DL), which provides twice the I/O pin count and functionality of standard small-outline packages in the same printed-circuit-board area. The SN54ABT16540 is characterized for operation over the full military temperature range of − 55 °C to 125°C. The SN74ABT16540 is characterized for operation from − 40 °C to 85°C.
