Functional Description

The CD54HCT154F3A is designed to take a 4-bit binary input and decode it into one of 16 mutually exclusive outputs. The device includes two enable inputs (E1 and E2), which must be at logic low for the decoder to function. When both enable inputs are active, all outputs are forced to a high state. The binary input data is presented at the A, B, C, and D inputs, and decoded output is available from Y0 to Y15.

Applications

With its wide operating voltage range and high-speed performance, the CD54HCT154F3A is suitable for a variety of digital applications. Common uses include:

• Data routing
• Memory address decoding
• Control signal generation
• Demultiplexing signals for data distribution
• Function selection in complex systems
