MM54HC154/MM74HC154
4-to-16 Line Decoder
General Description
This decoder utilizes advanced silicon-gate CMOS technology, and is well suited to memory address decoding or data
routing applications. It possesses high noise immunity, and
low power consumption of CMOS with speeds similar to low
power Schottky TTL circuits.
The MM54HC154/MM74HC154 have 4 binary select inputs
(A, B, C, and D). If the device is enabled these inputs determine which one of the 16 normally high outputs will go low.
Two active low enables (G1
cascading of decoders with little or no external logic.
and G2) are provided to ease
Connection Diagram Dual-In-Line Package
Each output can drive 10 low power Schottky TTL equivalent loads, and is functionally and pin equivalent to the
54LS154/74LS154. All inputs are protected from damage
due to static discharge by diodes to V
