SN74LS42D Description

Short technical summary and product information.

The SN74LS42D is a monolithic BCD-to-decimal decoder from Texas Instruments, part of the LS technology family. This integrated circuit consists of inverters and four-input NAND gates designed for decoding BCD input data into a 1-of-10 output.

 

Key electrical specifications include a supply voltage range of 4.75V to 5.25V and a maximum supply current of 10000µA. The device features 1 independent circuit with 1 input and 10 outputs. It operates within a temperature range of 0°C to 70°C.

 

The SN74LS42D is housed in a 16-SOIC package, suitable for surface mounting. Its outputs remain high for all invalid input conditions, making it versatile for applications such as 4-line-to-16-line decoders or 3-line-to-8-line decoders. The inputs and outputs are compatible with most TTL logic circuits, offering typical DC noise margins of one volt.

 

This decoder is ideal for digital logic applications requiring conversion from binary-coded decimal to a decimal output. Its robust design and standard packaging make it a reliable choice for various electronic systems.
