74LVC257A  
Quad 2-input multiplexer with 5 V tolerant inputs/outputs;  
3-state  
Rev. 8 — 31 August 2021  
Product data sheet  
1. General description  
The 74LVC257A is a quad 2-input multiplexer; 3-state. Inputs can be driven from either 3.3 V or  
5 V devices. This feature allows the use of these devices as translators in mixed 3.3 V and 5 V  
environments.  
Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.  
This device is fully specified for partial power down applications using IOFF. The IOFF circuitry  
disables the output, preventing the potentially damaging backflow current through the device when  
it is powered down.  
2. Features and benefits  
Overvoltage tolerant inputs to 5.5 V  
Wide supply voltage range from 1.2 V to 3.6 V  
CMOS low-power consumption  
Direct interface with TTL levels  
Output drive capability 50 Ω transmission lines at 85 °C  
IOFF circuitry provides partial Power-down mode operation  
Complies with JEDEC standard:  
JESD8-7A (1.65 V to 1.95 V)  
JESD8-5A (2.3 V to 2.7 V)  
JESD8-C/JESD36 (2.7 V to 3.6 V)  
ESD protection:  
HBM JESD22-A114F exceeds 2000 V  
MM JESD22-A115B exceeds 200 V  
CDM JESD22-C101E exceeds 1000 V  
Specified from -40 °C to +85 °C and -40 °C to +125 °C
