HEF4051B Datasheet – 8-Ch, Analog Multiplexer/Demultiplexer

Part Number: HEF4051B

Function: 8-channel analogue multiplexer/demultiplexer

Package: SOIC 16 Pin Type

Manufacturer: NXP Semiconductors.

Pinouts:

HEF4051B datasheet

 

Description

The HEF4051B is an 8-channel analog multiplexer/demultiplexer with three address inputs (S1 to S3), an active LOW enable input (E), eight independent inputs/outputs (Y0 to Y7) and a common input/output (Z).

The device contains eight bidirectional analog switches, each with one side connected to anindependent input/output (Y0 to Y7) and the other side connected to a common input/output (Z). With ELOW, one of the eight switches is selected (low-impedance ON-state) by S1 to S3. With EHIGH, all switches are in the high-impedance OFF-state, independent of S1 to S3. If break before make is needed, then it is necessary to use the enable input.

Features

1. Fully static operation

2. 5 V, 10 V, and 15 V parametric ratings

3. Standardized symmetrical output characteristics

4. Complies with JEDEC standard JESD 13-B

74HC4851 Datasheet – Analog Multiplexer / Demultiplexer

Part Number: 74HC4851

Function: 8-channel analog multiplexer/demultiplexer with injection-current effect control

Package: SO, TSSOP, DHVQFN 16 Pin Type

Manufacturer: NXP Semiconductors.

Pinouts:

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.

 

Applications:

1. Analog multiplexing and demultiplexing

2. Digital multiplexing and demultiplexing

3. Signal gating

4. Automotive application
