The MM74HC154 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 MM74HC154 have 4 binary select inputs (A, B, C, and\nD). If the device is enabled these inputs determine which\none of the 16 normally HIGH outputs will go LOW. Two active LOW enables (G1 and G2) are provided to ease\ncascading of decoders with little or no external logic. Each output can drive 10 low power Schottky TTL equivalent loads, and is functionally and pin equivalent to the 74LS154. All inputs are protected from damage due to static discharge by diodes to VCC and ground. Features  Typical propagation delay: 21 ns  Power supply quiescent current: 80 A Wide power supply voltage range: 26V Low input current: 1 A maximum
