Description

General part information

SN74ALVCH16271 Series

This 12-bit to 24-bit bus exchanger is designed for 1.65-V to 3.6-V VCCoperation.

The SN74ALVCH16271 is intended for applications in which two separate data paths must be multiplexed onto, or demultiplexed from, a single data path. This device is particularly suitable as an interface between conventional DRAMs and high-speed microprocessors.

A data is stored in the internal A-to-B registers on the low-to-high transition of the clock (CLK) input, provided that the clock-enable (CLKENA\) inputs are low. Proper control of these inputs allows two sequential 12-bit words to be presented as a 24-bit word on the B port.
