74HC251; 74HCT251  
8-input multiplexer; 3-state  
Rev. 6 — 8 February 2021  
Product data sheet  
1. General description  
The 74HC251; 74HCT251 is an 8-bit multiplexer with eight binary inputs (I0 to I7), three select  
inputs (S0 to S2) and an output enable input (OE). The select inputs select one of the eight binary  
inputs and route it to the complementary outputs (Y and Y). A HIGH on OE causes the outputs to  
assume a high-impedance OFF-state. Inputs include clamp diodes that enable 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)  
Input levels:  
For 74HC251: CMOS level  
For 74HCT251: TTL level  
Non-inverting data path  
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
