74LS398 General Description

The SN54/74LS398 and SN54/74LS399 are Quad 2-Port Registers. They are 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 on the LOW-to-HIGH transition of the Clock input. The SN54/74LS398 features both Q and Q inputs, while the SN54/74LS399 has only Q outputs.

74LS398 Features

• Select From Two Data Sources
• Fully Positive Edge-Triggered Operation
• Both True and Complemented Outputs on SN54/74LS398
• Input Clamp Diodes Limit High-Speed Termination Effects
