74HC4851 datasheet

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.
WithE 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.

Features : 

1. Injection-current cross coupling < 1 mV/mA

2. Wide supply voltage range from 2.0 V to 6.0 V for 74HC4851

3. ESD protection:

  (1) HBM JESD22-A114E exceeds 2000 V


  (2) CDM JESD22-C101C exceeds 1000 V
