The SN74HC138PWRE4 is an IC component, more precisely a 3-line to 8-line decoder/demultiplexer manufactured by Texas Instruments. This integrated circuit is widely used in digital electronics to decode and demultiplex binary-coded signals into separate output lines.
Key Features:
1. 3-line to 8-line Decoder: The SN74HC138PWRE4 features three input lines (A0, A1, and A2) that are used to decode eight different binary input combinations. These inputs determine which of the eight output lines will be active.
2. Active Low Outputs: The IC has eight active low outputs (Y0 to Y7) which provide separate output lines based on the decoded input combination. The selected output line is pulled low while the other outputs remain high.
3. Enable Input (G2A & G2B): This IC includes two enable inputs, G2A and G2B, which work together to control the functioning of the IC. When G2A and G2B are both held high, the decoder is enabled, and the selected output is determined by the input combination. However, when either G2A or G2B (or both) are held low, all the outputs remain high regardless of the input combination.
4. Wide Operating Voltage Range: The SN74HC138PWRE4 operates within a wide voltage range, from 2V to 6V
