74HC257; 74HCT257  
Quad 2-input multiplexer; 3-state  
Rev. 8 — 9 February 2021  
Product data sheet  
1. General description  
The 74HC257; 74HCT257 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  
.
2. Features and benefits  
Wide supply voltage range from 2.0 V to 6.0 V  
CMOS low power dissipation  
High noise immunity  
Latch-up performance exceeds 100 mA per JESD 78 Class II Level B  
Complies with JEDEC standards:  
JESD8C (2.7 V to 3.6 V)  
JESD7A (2.0 V to 6.0 V)  
Non-inverting data path  
3-state outputs interface directly with system bus  
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  
Specified from -40 °C to +85 °C and from -40 °C to +125 °C
