74LS298 - Quad 2-Port Register Multiplexer

General Description

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).

Key Features

  • s Select from two data sources s Fully edge-triggered operation s Typical power dissipation of 65 mW Ordering Code: Order Number DM74LS298N Package Number N16E Package.

DM74LS298 Quad 2-Port Register Multiplexer with Storage October 1988 Revised March 2000 DM74LS298 Quad 2-Port Register Multiplexer with Storage General Description 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 synchronous with the HIGH-to-LOW transition of the Clock input.
