36-Bit Registered Bus Transceivers With 3-State Outputs

The 'ABTH32543 are 36-bit registered transceivers that contain two sets of D-type Latches for temporary storage of data flowing in either direction. These devices CAN be used as two 18-bit transceivers or one 36-bit transceiver. Separate latch-enable (LEAB or LEBA) and output-enable (OEAB or OEBA) inputs are provided for each Register to permit independent control in either direction of data flow.
The A-to-B enable (CEAB) input must be low to enter data from A or to output data from B. If CEAB is low and LEAB is low, the A-to-B Latches are transparent; a subsequent low-to-high transition of LEAB puts the A Latches in the storage mode. With CEAB and OEAB both low, the 3-state B outputs are active and reflect the data present at the output of the A Latches Data flow from B to A is similar but requires using the CEBA, LEBA, and OEBA inputs.
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 is provided to hold unused or floating data inputs at a valid Logic level.
The SN54ABTH32543 is characterized for operation over the full military temperature range of -55C to 125C. The SN74ABTH32543 is characterized for operation from -40C to 85C
