The CD74HC154EN is a 4-to-16 Line Decoder/Demultiplexer with two enable inputs, E1 and E2. A High on either enable input forces the output into the High state. The demultiplexing function is performed by using the four input lines, A0 to A3, to select the output lines Y0\ to Y15\ and using one enable as the data input while holding the other enable low.
Two enable inputs to facilitate demultiplexing and cascading functions
10 LSTTL loads standard outputs, 15 LSTTL loads bus driver outputs
Balanced propagation delay and transition times
Significant power reduction compared to LSTTL logic ICs
NIL= 30%, NIH = 30% of VCC at VCC = 5V High noise immunity
