Working Principles
The CD74HCT238M96 is designed to decode a 3-bit binary code into 8 mutually exclusive outputs. The address inputs (A0, A1, A2) determine which output line (Y0-Y7) will be active based on the binary code applied. When the enable inputs (E1, E2, E3) are high, the address inputs are latched, and the corresponding output line is activated. The IC operates at high speed with low power consumption, making it ideal for decoding and demultiplexing applications.
