Product Summary
The MC74HC154N is a 1-of-16 Decoder/Demultiplexer. The MC74HC154N is identical in pinout to the LS154. The MC74HC154N inputs are compatible with standard CMOS outputs; with pullup resistors, the MC74HC154N is compatible with LSTTL outputs. The MC74HC154N, when enabled, selects one of 16 active–low outputs. Two active–low Chip Selects are provided to facilitate the chip–select, demultiplexing, and cascading functions. When either Chip Select is high, all outputs are high. The demultiplexing function of the MC74HC154N is accomplished by using the Address inputs to select the desired device output. Then, while holding one chip select input low, data can be applied to the other chip select input.
