SN54LVTH162541, SN74LVTH162541

3.3-V ABT 16-BIT BUFFERS/DRIVERS

WITH 3-STATE OUTPUTS

POST OFFICE BOX 655303

description (continued)

The outputs, which are designed to source or sink up to 12 mA, include equivalent 22-

Ω series resistors to

reduce overshoot and undershoot.

the minimum value of the resistor is determined by the current-sinking capability of the driver.

Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.

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 SN54LVTH162541 is characterized for operation over the full military temperature range of –55

°C to 125°C.

The SN74LVTH162541 is characterized for operation from –40

°C to 85°C.
