General Description

/ORDERING INFORMATION The SN54LVC646A octal bus transceiver and register is designed for 2.7-V to 3.6-V VCC operation.

This device consists of bus-transceiver circuits, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the input bus or from the internal registers.

Data on the A or B bus is clocked into the registers on the low-to-high transition of the appropriate clock (CLKAB or CLKBA) input.
