SN54LVT162240, SN74LVT162240
3.3-V ABT 16-BIT BUFFERS/DRIVERS
WITH 3-STATE OUTPUTS
SCBS719 – JULY 2000

POST OFFICE BOX 655303
DALLAS, TEXAS 75265
description (continued)
The outputs, which are designed to source or sink up to 12 mA, include equivalent 22-
series resistors to
reduce overshoot and undershoot.
When V
CC
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 V
CC
through a pullup resistor;
the minimum value of the resistor is determined by the current-sinking capability of the driver.
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 SN54LVT162240 is characterized for operation over the full military temperature range of –55
°
C to 125
°
C.
The SN74LVT162240 is characterized for operation from –40
°
C to 85
°
C.
