Product line
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:
For AiP74HC257: CMOS level
For AiP74HCT257: TTL level
Non-inverting data path
3-state outputs interface directly with system bus
Specified from -40℃ to +105℃
Packaging information: DIP16/SOP16/TSSOP16
