Specification

Description

The SN7442AN is a BCD (Binary-Coded Decimal) to Decimal Decoder IC, belonging to the 74xx series of integrated circuits.

Here's a Brief Description:

Functionality: The SN7442AN is a digital logic IC that decodes a four-bit BCD input (Binary-Coded Decimal) into its corresponding decimal output.

Inputs: It typically has four BCD input lines (A, B, C, and D), representing a binary value from 0000 to 1001 in binary-coded decimal.

Outputs: The IC provides ten outputs (0 to 9), each representing the decimal equivalent of the BCD input.

Decimal Outputs: The IC generates an active-low output for the decimal value represented by the BCD input. For example, if the BCD input is 0101 (5 in decimal), the output for 5 will be active low while others are high.

Active-Low Outputs: The outputs are active-low, meaning that when a particular decimal output is active, its corresponding output pin goes low (logical 0), and others remain high (logical 1).

Power Supply: The SN7442AN typically operates with a power supply voltage in the range of 4.75 to 5.25 volts.

Logic Family: The "74" in SN7442AN indicates that it belongs to the TTL (Transistor-Transistor Logic) logic family.

Package Type: The "N" in SN7442AN indicates the package type, often available in various package options, commonly a 16-pin dual in-line package (DIP).

Applications:

The SN7442AN is used in applications where BCD data needs to be converted into decimal data, such as in BCD to 7-segment display converters and other digital display applications.

Propagation Delay: The propagation delay is the time taken for a change in input to result in a change at the output. TTL series devices generally have moderate propagation delays.
