description
The ’ABTH32245 is a 36-bit (quad 9-bit) noninverting 3-state transceiver designed for synchronous two-way
communication between data buses. The control-function implementation minimizes external timing
requirements.
This device can be used as four 9-bit transceivers, two18-bit transceivers, or one 36-bit transceiver. It allows
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) inputs. The output-enable (OE) inputs 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-impedance 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.
Active bus-hold circuitry holds unused or floating data inputs at a valid logic level.
