DM74LS298

Quad 2-Port Register Multiplexer with Storage

General Description

Features

■ Select from two data sources

■ Fully edge-triggered operation

■ Typical power dissipation of 65 mW

The DM74LS298 is a quad 2-port register. It is the logical

equivalent of a quad 2-input multiplexer followed by a quad

4-bit edge-triggered register.

A Common Select input

selects between two 4-bit input ports (data sources). The

selected data is transferred to the output register synchro-

nous with the HIGH-to-LOW transition of the Clock input.
