Description

The 4ABT32245 are 36-bit (quad 9-bit) noninverting 3-state transceivers designed for synchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements.

These 4ABT32245 devices can be used as four 9-bit transceivers, two18-bit transceivers, or one 36-bit transceiver. They allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending upon the logic level at the direction-control (DIR) inputs. The output-enable (OE) inputs can be used to disable the device so that the buses are effectively isolated.

To ensure the high-impedance state of 4ABT32245 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.

Active bus-hold circuitry of 4ABT32245 holds unused or floating data inputs at a valid logic level.The SN54ABT32245 is characterized for operation over the full military temperature range of 55°C to 125°C. The SN74ABT32245 is characterized for operation from 40°C to 85°C.
