2 / 14 page www.ti.com DESCRIPTION/ORDERING INFORMATION (CONTINUED) SN54LVTH162241 ,, SN74LVTH162241 3.3-V ABT 16-BIT BUFFERS/DRIVERS WITH 3-STATE OUTPUTS SCBS692E – MAY 1997 – REVISED NOVEMBER 2006 When VCC is between 0 and 1.5 V, the devices are in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 1.5 V, OE should be tied to VCC through a pullup resistor and OE should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the current-sinking/current-sourcing capability of the driver. Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level. These devices are fully specified for hot-insertion applications using Ioff and power-up 3-state. The Ioff circuitry disables the outputs, preventing damaging current backflow through the devices when they are powered down. The power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down, which prevents driver conflict. The SN54LVTH162241 is characterized for operation over the full military temperature range of –55 °C to 125°C. The SN74LVTH162241 is characterized for operation from –40 °C to 85°C.
