Description

The 'ABTH162245 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 'ABTH162245 devices can be used as two 8-bit transceivers 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.

The A-port outputs of 'ABTH162245 , which are designed to source or sink up to 12 mA, include equivalent 25- series resistors to reduce overshoot and undershoot.Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level. To ensure the high-impedance state during power up or power down, 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 SN54ABTH162245 is characterized for operation over the full military temperature range of 55°C to 125°C. The SN74ABTH162245 is characterized for operation from 40°C to 85°C.
