The 74HC/HCT154 decoders accept four active HIGH binary address inputs and provide 16 mutually exclusive active LOW outputs.
The Philips 74HC/HCT154 is a high-speed Si-gate CMOS device designed as a 4-to-16 line decoder or demultiplexer. It accepts four active HIGH binary address inputs and provides sixteen mutually exclusive active LOW outputs, making it suitable for decoding applications in digital logic circuits.
The device acts as a 4-to-16 line decoder or demultiplexer that converts four binary-coded inputs into one of 16 mutually exclusive outputs.
The two enable inputs must both be LOW to enable the decoder outputs.
The maximum propagation delay for the 74HCT version is 53 ns.
