description

These octal bus transceivers are designed

specifically for low-voltage (3.3-V) V operation,

but with the capability to provide a TTL interface

to a 5-V system environment.

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.

When V

is between 0 and 1.5 V, the device is 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

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

through a pullup resistor;

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 SN54LVT245B is characterized for operation over the full military temperature range of –55°C to 125°C.

The SN74LVT245B is characterized for operation from –40°C to 85°C.

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

parameters.
