SN74LS298D集成电路（IC）的信号开关多路复用器解码器规格书PDF中文资料

QUAD 2-INPUT MULTIPLEXER WITH STORAGE

The SN54/74LS298 is a Quad 2-Port Register. It is the logical equivalent of aquad 2-input multiplexer followed by a quad 4-bit edge-triggered register. A Common Select input selects between two 4-bit input ports (datasources.) The selected data is transferred to the output register synchronous with the HIGH to LOW transition of the Clock input.

TheLS298 is fabricated with the Schottky barrier process for high speed and is completely compatible with all Motorola TTL families.

• Select From Two Data Sources

• Fully Edge-Triggered Operation

• Typical Power Dissipation of 65 mW

• Input Clamp Diodes Limit High Speed Termination Effects
