description

These octal bus transceivers are designed specifically for low-voltage (3.3-V) V

capability to provide a TTL interface to a 5-V system environment.

operation, but with the

These devices are designed for asynchronous communication between data buses. They transmit data 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 the buses are effectively isolated.

Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.

The B-port outputs, which are designed to source or sink up to 12 mA, include equivalent 22-Ω series resistors

to reduce overshoot and undershoot.

When V 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

through a pullup resistor;

the minimum value of the resistor is determined by the current-sinking capability of the driver.

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.

DATA information current as of publication date. Products conform to

specifications per the terms of Texas Instruments standard warranty.

Production processing does not necessarily include testing of all
