74HC237 datasheet

 

Description

The 74HC237 is a high-speed Si-gate CMOS device and is pin compatible with low-power Schottky TTL (LSTTL). The device isspecified in compliance with JEDEC standard no. 7A. The IC essentially combines the 3-to-8 decoder function with a 3-bit storage latch. The device is ideally suited for implementing non-overlapping decoders in 3-state systems and strobed (stored address) applications in bus oriented systems.

Features

1. Combines 3-to-8 decoder with 3-bit latch

2. Multiple input enable for easy expansion or independent controls

3. Active HIGH mutually exclusive outputs

4. Low-power dissipation

74HC42 Datasheet PDF – BCD to decimal decoder – Philips

Posted on by pinout

Part Number: 74HC42

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

Package: DIP, SOP 16 Type

Manufacturer: 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
