MM74HC151
8-Channel Digital Multiplexer
General Description
The MM74HC151 high speed Digital multiplexer utilizes
advanced silicon-gate CMOS technology. Along with the
high noise immunity and low power dissipation of standard
CMOS integrated circuits, it possesses the ability to drive
10 LS-TTL loads. The MM74HC151 selects one of the 8
data sources, depending on the address presented on the
A, B, and C inputs. It features both true (Y) and comple-
ment (W) outputs. The STROBE input must be at a low
logic level to enable this multiplexer. A high logic level at
the STROBE forces the W output HIGH and the Y output
LOW.
The 74HC logic family is functionally as well as pin-out
compatible with the standard 74LS logic family. All inputs
are protected from damage due to static discharge by inter-
nal diode clamps to V
CC
and ground.
Features
■ Typical propagation delay data select to output Y: 26 ns
■ Wide operating supply voltage range: 2–6V
■ Low input current: 1 µA maximum
■ Low quiescent supply current: 80 µA maximum (74HC)
■ High output drive current: 4 mA minimum
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.

Absolute Maximum Ratings(Note 1)
(Note 2)
Recommended Operating
Conditions
Note 1: Absolute Maximum Ratings are those values beyond which dam-
age to the device may occur.
Note 2: Unless otherwise specified all voltages are referenced to ground.
Note 3: Power Dissipation temperature derating — plastic “N” package: −
12 mW/°C from 65°C to 85°C.
DC Electrical Characteristics (Note 4)
Note 4: For a power supply of 5V ±10% the worst case output voltages (V
OH
, and V
OL
) occur for HC at 4.5V. Thus the 4.5V values should be used 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 3.85V.) The worst case leakage cur-
rent (I
IN
, I
CC
, and I
OZ
) occur for CMOS at the higher voltage and so the 6.0V values should be used.
