SN54LVTH2245, SN74LVTH2245
3.3-V ABT OCTAL BUS TRANSCEIVERS
WITH 3-STATE OUTPUTS
SCBS707C – SEPTEMBER 1997 – REVISED APRIL 1999

POST OFFICE BOX 655303
DALLAS, TEXAS 75265
description (continued)
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 SN54LVTH2245 is characterized for operation over the full military temperature range of –55
°
C to 125
°
C.
The SN74LVTH2245 is characterized for operation from –40
°
C to 85
°
C.
