SN54LS398 Datasheet, Equivalent, 2-PORT REGISTER.QUAD 2-PORT REGISTER QUAD 2-PORT REGISTER |
| Part | SN54LS398 |
|---|---|
| Description | QUAD 2-PORT REGISTER |
| Feature | QUAD 2-PORT REGISTER
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. SN54/74LS398 SN54/74LS399 QUAD 2-PORT REGISTER LOW POWER SCHOTTKY • • • • Select From Two Data Sources Fully Positive Edge-T. |
