The SN74ABT16652DLR from Texas Instruments is a high-performance, dual 16-bit bus transceiver and register specifically designed for driving high-capacitive loads and low-impedance backplanes.

• Flip-Flops: features two sets of D-type flip-flops, which are controlled by two separate clock (CLKAB and CLKBA) inputs.
• Operation: allows the device to operate in either direction, transmitting data from the A bus to the B bus or vice versa, depending on the logic level @ the direction-control (DIRAB and DIRBA) inputs.
• Latch-Enable: equipped with a latch-enable (LEAB and LEBA) input that can hold data @ the outputs, regardless of changes @ the data inputs.
• Output-Enable: The output-enable (OEAB and OEBA) inputs, when set to high, disable both the A and B outputs
• Data Inputs: designed with 'bus-hold' data inputs, which eliminate the need for external pull-up or pull-down resistors and ensure that the inputs remain @ a valid logic level.
• Voltage Range: operates on a 4.5V to 5.5V voltage range
• Package: available in a 56-pin SSOP (DL) package
