SN74AHC138D is an integrated circuit (IC) component that belongs to the SN74AHC family. It is a 3-to-8 line decoder/demultiplexer with active-high outputs. This IC is widely used in various electronic devices for decoding binary-coded data into an appropriate output format. Here is an overview of its key features:
1. High-Speed Operation: The SN74AHC138D operates at high-speed, making it suitable for applications that require quick response and efficient data processing.
2. Decoder/Demultiplexer: This IC acts as a decoder when the enable (E) input is active-low, and as a demultiplexer when the E input is active-high. It takes a 3-bit binary input and generates 8 unique outputs based on the input combination.
3. Active-High Outputs: The outputs (Y0 to Y7) of SN74AHC138D are active-high, meaning they produce logic high levels when enabled and logic low levels when disabled.
4. Three Enable Inputs: This IC has three enable inputs (E1, E2, and E3) that can be used to enable or disable the decoding process. When all three enable inputs are high, the outputs are disabled (set to logic low).
5. Wide Operating Voltage Range: SN74AHC138D operates within a wide voltage range of 2V to 5.5V, providing flexibility in different operating conditions
