The SN5497J is an integrated circuit (IC) component, specifically a dual 3-to-8 line decoder/demultiplexer. It is part of the SN5400 series family of TTL (Transistor-Transistor Logic) chips manufactured by Texas Instruments. This IC is widely used in digital electronics to decode and demultiplex data signals.
The SN5497J is designed to simplify complex decoding operations in various applications, such as address decoding in memory systems, output control in microprocessor-based systems, and code conversions in data communication systems. It has two identical 3-to-8 line decoders/demultiplexers within a single package.
Key features of the SN5497J include:
1. Decoder/Demultiplexer Functionality: The primary purpose of the SN5497J is to decode or demultiplex multiple inputs into multiple outputs. Each decoder within the IC can accept three binary inputs (A0, A1, and A2), which collectively define one of the eight mutually exclusive outputs (Y0-Y7).
2. Binary Output: The decoded output lines are presented in a binary format, where only one output line is active (logic LOW) at a time. The specific output line is determined by the input binary code, allowing flexible signal routing and control.
3. Enable Input: The IC includes an active-Low enable input (G), which allows the user to enable or disable the functionality of the decoders
