74LS42 Datasheet – 4-Line BCD to 10-Line Decimal Decoder

Part Number : 74LS42

Function : 4-LINE BCD TO 10-LINE DECIMAL DECODER

Package : DIP 16 Pin, PLCC 18 Pin

Manufacturers : Texas Instruments

Pinouts :

74LS42 datasheet

 

Description :

These monolithic BCD-to-decimal decoders consist of eight inverters and ten four-input NAND gates. The inverters are connected in pairs to make BCD input data availible for decoding by the NAND gates. Full decoding of valid input logic ensures that all outputs remain off for all invalid input conditions.

Features

1. All ouputs are high for invalid input conditions
2. Also for application as
(1) 4-Line-to-16-Line Decoders
(2) 3-Line-to-8-Line Decoders
3. Diode-Clamped Inputs

74HC30 Datasheet PDF

Part Number : 74HC30

Function : High Speed CMOS Logic 8-Input NAND Gate

Manufacturers : Texas Instruments

Pinouts :

74HC30 datasheet

Description :

The ’HC30 and ’HCT30 eachcontain an 8-inputNAND gate in one package. They provide the system designer with the direct implementation of the positive logic 8-input NAND function.

Logic gates utilize silicon gate CMOS technology to achieve operating speeds similar to LSTTL gates with the low power consumption of standard CMOS integrated circuits.

 

All devices have the ability to drive 10 LSTTL loads. The HCT logic family is functionally pin compatible with the standard LS logic family.
