1 / 8 page  SN74ABT16241 16BIT BUFFER/DRIVER WITH 3STATE OUTPUTS SCBS347 − MAY 1994 SPICE I/O MODEL Copyright 1994, Texas Instruments Incorporated 2−1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251−1443 • Member of the Texas Instruments Widebus Family • State-of-the-Art EPIC-ΙΙB BiCMOS Design Significantly Reduces Power Dissipation • 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) • Packaged in Plastic 300-mil Shrink Small-Outline (SSOP) Packages description The SN74ABT16241 is a 16-bit buffer and line driver designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The device can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. This device provides true outputs and complementary output-enable (OE and OE) inputs. 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. OE should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver. The SN74ABT16241 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 SN74ABT16241 is characterized for operation from − 40 °C to 85°C.
