DESCRIPTION/ORDERING INFORMATION (CONTINUED)
3.3-V ABT 16-BIT BUFFERS/DRIVERS
WITH 3-STATE OUTPUTS
SCBS693D – 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 SN54LVTH16241 is characterized for operation over the full military temperature range of –55
°C to 125°C.
The SN74LVTH16241 is characterized for operation from –40
°C to 85°C.
