DESCRIPTION
The 74LV154 is a low-voltage CMOS device and is pin and function compatible with 74HC/HCT154. The 74LV154 decoders accept four active HIGH binary address inputs (A0 to A3) and provide 16 mutually exclusive active LOW outputs(Y0 to Y15). The 2-input enable inputs (E0, E1) can be used to strobe the decoder to eliminate the normal decoding “glitches” on the outputs, or it can be used for expansion of the decoder. The enable input has two AND’ed inputs which must be LOW to enable the outputs. The 74LV154 can be used as a 1-to-16 demultiplexer by using one of th……
