74HC139 Datasheet – Decoder / Demultiplexer

Part Number : 74HC139

Function : Dual 2-to-4 line Decoder/Demultiplexer

Package : DIP, SOP 16 Pin Type

Manufacturers : Philips Electronics ( https://www.nxp.com/ )

Pinouts :

74HC139 datasheet


Description :

The 74HC139, 74HCT139 decodes two binary weighted address inputs (nA0, nA1) to four mutually exclusive outputs (nY0 to nY3). Each decoder features an enable input (nE).

When nEis HIGH all outputs are forced HIGH. The enable input can be used as the data input for a 1-to-4 demultiplexer application. Inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC.

Features :

1. Demultiplexing capability

2. Two independent 2-to-4 decoders

3. Multifunction capability

4. Active LOW mutually exclusive outputs

5. Output capability: standard

6. ICC category: MSI


Applications :

1. Memory decoding or data-routing

2. Code conversion

74HC4851-Q100 Datasheet – Analog Multiplexer / Demultiplexer

Part Number : 74HC4851-Q100

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

Package : SO 16, TSSOP 16, DHVQFN 16 Pin Type

Manufacturers : NXP Semiconductors.

Pinouts :

74HC4851-Q100 datasheet


Description :

The 74HC4851-Q100, 74HCT4851-Q100 are high-speed Si-gate CMOS devices and are specified in compliance with JEDEC standard no. 7A.

The devices 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.

Applications :

1. Analog multiplexing and demultiplexing

2. Digital multiplexing and demultiplexing

3. Signal gating

4. Automotive application
