Description

General part information

SN74LVCH16646A Series

This 16-bit bus transceiver and register is designed for 1.65-V to 3.6-V VCCoperation.

The SN74LVCH16646A can be used as two 8-bit transceivers or one 16-bit transceiver. The 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. Figure 1 illustrates the four fundamental bus-management functions that can be performed with the SN74LVCH16646A.
