The SN54HCT138J is an integrated circuit (IC) component that belongs to the SNx4HCTxx family of 3-line-to-8-line decoders/demultiplexers. It is manufactured by Texas Instruments and designed specifically for high-speed CMOS logic applications.
This IC component is capable of taking three binary weighted inputs (A0, A1, and A2) and generating up to eight mutually exclusive outputs (Y0 to Y7) based on the active low Enable (E\). The decoder/demultiplexer uses complementary open collector outputs to provide both true (Y0 to Y7) and inverted (Y0\ to Y7\) outputs, offering flexibility in various applications.
Key Features:
1. High-Speed Operation: The SN54HCT138J is designed to operate at high speeds, making it suitable for time-critical applications.
2. Wide Voltage Range: The IC component has a wide operating voltage range of 4.5V to 5.5V, making it compatible with different power supply levels.
3. 3-Line to 8-Line Decoding: It can decode any valid logic combination of the three input lines (A0, A1, and A2) into output selections (Y0 to Y7) through its internal decoding logic.
4. Active Low Enable (E\): The active low Enable input (E\) is used to enable or disable the decoder/demultiplexer
