2 / 14 page SN54LVT16500, SN74LVT16500 3.3-V ABT 18-BIT UNIVERSAL BUS TRANSCEIVERS WITH 3-STATE OUTPUTS SCBS146D – MAY 1992 – REVISED NOVEMBER 1996 2 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 description (continued) Data flow for B to A is similar to that of A to B but uses OEBA, LEBA, and CLKBA. The output enables are complementary (OEAB is active high and OEBA is active low). Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level. 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 SN74LVT16500 is available in TI’s shrink small-outline (DL) and thin shrink small-outline (DGG) packages, which provide twice the I/O pin count and functionality of standard small-outline packages in the same printed circuit board area. The SN54LVT16500 is characterized for operation over the full military temperature range of –55 °C to 125°C. The SN74LVT16500 is characterized for operation from –40 °C to 85°C.
