74HC4851; 74HCT4851  
8-channel analog multiplexer/demultiplexer with  
injection-current effect control  
Rev. 4 — 15 May 2023  
Product data sheet  
1. General description  
The 74HC4851; 74HCT4851 are high-speed Si-gate CMOS devices and are specified in  
compliance with JEDEC standard no. 7A.  
The 74HC4851; 74HCT4851 are 8-channel analog multiplexers/demultiplexers with three digital  
select inputs (S0 to S2), an active-LOW enable input (E), eight independent inputs/outputs (Y0  
to Y7) and a common input/output (Z). The devices feature injection-current effect control, which  
has excellent value in automotive applications where voltages in excess of the supply voltage are  
common.  
With E LOW, one of the eight switches is selected (low impedance ON-state) by S0 to S2.  
With E HIGH, all switches are in the high-impedance OFF-state, independent of S0 to S2.  
The injection-current effect control allows signals at disabled analog input channels to exceed the  
supply voltage without affecting the signal of the enabled analog channel. This eliminates the need  
for external diode/resistor networks typically used to keep the analog channel signals within the  
supply-voltage range.  
2. Features and benefits  
•
Injection-current cross coupling < 1 mV/mA
