DESCRIPTION/ORDERING INFORMATION (CONTINUED)
SN54LVTH162240 , , SN74LVTH162240
3.3-V ABT 16-BIT BUFFERS/DRIVERS
WITH 3-STATE OUTPUTS
SCBS685F – MARCH 1997 – REVISED NOVEMBER 2006
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 I
off
and power-up 3-state. The I
off
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 SN54LVTH162240 is characterized for operation over the full military temperature range of –55 ° C to 125 ° C.
The SN74LVTH162240 is characterized for operation from –40 ° C to 85 ° C.
