Fairchild MTC24 4-to-16 line decoder Datasheet

Revised July 2003
MM74HC154
4-to-16 Line Decoder
General Description
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
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 and G2) are provided to ease
cascading 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 µA
■ Wide power supply voltage range: 2–6V
■ Low input current: 1 µA maximum

Note 5: For a power supply of 5V ±10% the worst case output voltages (VOH, and VOL) occur for HC at 4.5V. Thus the 4.5V values should be used when
designing with this supply. Worst case VIH and VIL occur at VCC = 5.5V and 4.5V respectively. (The VIH value at 5.5V is 3.85V.) The worst case leakage current (IIN, ICC, and IOZ) occur for CMOS at the higher voltage and so the 6.0V values should be used.
