带三态控制的4路2输入多路复用器

The AiP74HC/HCT257 is a quad 2-input multiplexer with 3-state outputs. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. •Input levels:\n• For AiP74HC257: CMOS level\n• For AiP74HCT257: TTL level\n•Non-inverting data path\n•3-state outputs interface directly with system bus\n•Specified from -40℃ to +125℃\n•Packaging information: DIP16/SOP16/TSSOP16;
