POST OFFICE BOX 655303

description (continued)

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 SN54LVTH16541 is characterized for operation over the full military temperature range of –55

°C to 125°C.

The SN74LVTH16541 is characterized for operation from –40

°C to 85°C.
