The 54ACT138DM is an integrated circuit (IC) component primarily designed for decoding and demultiplexing applications. It is a member of the 54ACT series, which features high-speed operation combined with low power consumption. Here is a brief overview and key features of the 54ACT138DM:
1. Overview:
- The 54ACT138DM is an 8-input decoder/demultiplexer. It takes three binary select inputs (A, B, and C) to determine which one of the eight outputs (Y0-Y7) will be activated.
- This IC chip is built using advanced bipolar technology, offering higher speed and improved noise immunity compared to its predecessors.
2. Key Features:
- 3-to-8 Decoding: The main function of the 54ACT138DM is to decode the three select inputs (A, B, and C) and enable only one of the eight outputs based on the input conditions.
- Active-LOW Outputs: The outputs (Y0-Y7) are active-low, meaning that when the corresponding combination of select inputs is applied, the respective output will be driven to a low logic level (0V).
- High-Speed Operation: The 54ACT138DM operates at high-speed, facilitating quick decoding and demultiplexing operations within a digital system.
- Wide Operating Voltage Range: This IC supports a wide voltage range of 4.5V to 5
