descriptionThe ’ALVTH162245 devices are 16-bit (dual-octal) noninverting 3-state transceivers designed for 2.5-V or 3.3-VCC operation, but with the capability to provide a TTL interface to a 5-V system environment.
These devices can be used as two 8-bit transceivers or one 16-bit transceiver. They allow data transmission
from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control
(DIR) input. The output-enable (OE) input can be used to disable the device so that the buses are effectively
isolated.
The A-port outputs, which are designed to source or sink up to 12 mA, include equivalent 30-Ω series resistors
to reduce overshoot and undershoot.
These devices are fully specified for hot-insertion applications using Ioff and power-up 3-state. The Ioff circuitry
disables the outputs, preventing damaging current backflow through the device when it is 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.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level. Use of pullup
or pulldown resistors with the bus-hold circuitry is not recommended.

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
