description/ordering information
The SN74LVTH16245A is a 16-bit (dual-octal) noninverting 3-state transceiver designed for low-voltage (3.3-V)
V_CC operation, but with the capability to provide a TTL interface to a 5-V system environment.
This device can be used as two 8-bit transceivers or one 16-bit transceiver. It allows 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 devices so that the buses are isolated.
Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors
with bus-hold circuitry is not recommended.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
