DESCRIPTION

The 'ABT16245A devices are 16-bit noninverting 3-state transceivers designed for synchronous two-way

communication between data buses. The control-function implementation minimizes external timing

requirements.

These devices can be used as two 8-bit transceviers 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.

When VCC is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down.

However, to ensure the high-impendance state above 2.1 V, OE should be tied to VCC through a pullup resistor;

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

The SN54ABT16245A is characterized for operation over the full military temperature range of –55°C to 125°C.

The SN74ABT16245A is characterized for operation from –40°C to 85°C.
