74HC42 Datasheet PDF – BCD to decimal decoder – Philips

Part Number : 74HC42

Function : BCD to decimal decoder (1-of-10)

Package : DIP, SOP 16 Type

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

Pinouts :

74HC42 datasheet

Description :

The 74HC42 / 74HCT42 decoders accept four active HIGH BCD  inputs and provide 10 mutually exclusive active LOW outputs. The active LOW outputs facilitate addressing other MSI circuits with active LOW input enables.

The logic design of the “42” ensures that all outputs are HIGH when binary codes greater than nine are applied to the inputs.

Features

1. Mutually exclusive outputs

2. 1-of-8 demultiplexing capability

3. Outputs disabled for input codes above nine

4. Output capability: standard

5 ICCcategory : MSI

Pinouts :

SN74LS47N datasheet

 

Description :

The SN74LS47N feature active-low outputs designed for driving common-anode LEDs or incandescent indicators directly. Display patterns for BCD input counts above 9 are unique symbols to authenticate input conditions. Input and outputs are entirely compatible for use with TTL logic ouputs.

Absolute Maximum Ratings

1. Supply voltage, Vcc = 7 V
2. Input Volage : 5.5V
3. Current forced into any ouput in the off state : 1 mA
