The 74HC257 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.
Features:-
• Non-inverting data path
• 3-state outputs interface directly with system bus
• Complies with JEDEC standard no. 7A
• Input levels:
- For 74HC257: CMOS level
- For 74HCT257: TTL level
• ESD protection:
- HBM JESD22-A114F exceeds 2000 V
- MM JESD22-A115-A exceeds 200 V
• Multiple package options
