74HC4851  
8-channel analog multiplexer/demultiplexer with  
injection-current effect control  
Rev. 01 — 9 March 2007  
Product data sheet  
1. General description  
The 74HC4851 is a high-speed Si-gate CMOS device and is specified in compliance with  
JEDEC standard no. 7A.  
The 74HC4851 is an 8-channel analog multiplexer/demultiplexer 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 device features 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  
I Injection-current cross coupling < 1 mV/mA  
I Wide supply voltage range from 2.0 V to 6.0 V  
I ESD protection:  
N HBM JESD22-A114D Class 2. Exceeds 2000 V  
N MM JESD22-A115-A exceeds 200 V  
N CDM JESD22-C101C exceeds 1000 V  
I Latch-up performance exceeds 100 mA per JESD 78 Class II  
I Low ON-state resistance:  
N 400 (typical) at VCC = 2.0 V  
N 215 (typical) at VCC = 3.0 V  
N 120 (typical) at VCC = 3.3 V  
N 76 (typical) at VCC = 4.5 V  
N 59 (typical) at VCC = 6.0 V
