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.

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.

These devices are fully specified for hot-insertion applications using I and power-up 3-state. The I circuitry

off

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 SN54LVTH245A is characterized for operation over the full military temperature range of –55°C to 125°C.

The SN74LVTH245A is characterized for operation from –40°C to 85°C.
