MM74HC154
4-to-16 Line Decoder
General Description
The MM74HC154 decoder utilizes advanced silicon-gate
CMOS technology, and is well suite d to memory address
decoding or data routing applications. It posse sses 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 e nabled these inputs de termine 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 p ower Schottk y TTL eq uiva-
lent loads, and is functionally and pin equivalent to the
74LS154. All inputs are protected from damage due to
static discharge by diodes to V
CC
and ground.
Features
■ Typical propagation delay: 21 ns
■ Power supp ly quiescent current: 80 µA
■ Wide power supply voltage range: 2–6V
■ Low input current: 1 µA maximum

Recommended Operating
Conditions
Note 2: Absolute Maximum Ra tings are those valu es beyond w hich dam-
age to the device may occur.
Note 3: Unless otherwise specified all voltages are referenced to ground.
Note 4: Power Dissipation te mperature d erating — pl astic “N” pa ckage: −
12 mW/°C from 65°C to 85°C.
DC Electrical Characteristics (Note 5)
Note 5: For a powe r supply o f 5V ±10% the worst case output voltages (V
OH
, and V
OL
) occur for HC at 4.5V. Thus the 4. 5V valu es shou ld be u sed when
designing with this supply. Worst case V
IH
and V
IL
occur at V
CC
= 5.5V and 4.5V respectively. (The V
IH
value at 5.5V is 3 .8 5V.) The worst c as e leakage cur-
rent (I
IN
, I
CC
, and I
OZ
) occur for CMOS at the higher voltage and so th e 6. 0V values should be used.
