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.

CPD is used to determine the dynamic power dissipation (PD in µW):
PD = CPD × VCC2 × fi + ∑{(CL + Csw) × VCC2 × fo} where:
fi = input frequency in MHz;
fo = output frequency in MHz;
∑{(CL + Csw) × VCC2 × fo} = sum of outputs;
CL = output load capacitance in pF;
Csw = switch capacitance in pF;
VCC = supply voltage in V.

products are for illustrative purposes only. NXP Semiconductors makes no
representation or warranty that such applications will be suitable for the
specified use without further testing or modification.
Limiting values — Stress above one or more limiting values (as defined in
the Absolute Maximum Ratings System of IEC 60134) may cause permanent
damage to the device. Limiting values are stress ratings only and operation of
the device at these or any other conditions above those given in the
Characteristics sections of this document is not implied. Exposure to limiting
values for extended periods may affect device reliability.
