MC74HC151A
8-Input Data
Selector/Multiplexer
High−Performance Silicon−Gate CMOS
The MC74HC151 is identical in pinout to the LS151. The device
inputs are compatible with standard CMOS outputs; with pullup
resistors, they are compatible with LSTTL outputs.
This device selects one of the eight binary Data Inputs, as
determined by the Address Inputs. The Strobe pin must be at a low
level for the selected data to appear at the outputs. If Strobe is high, the
Y output is forced to a low level and the Y output is forced to a high
level.
The HC151 is similar in function to the HC251 which has 3−state
outputs.
Features
Output Drive Capability: 10 LSTTL Loads
Outputs Directly Interface to CMOS, NMOS, and TTL
Operating Voltage Range: 2 to 6 V
Low Input Current: 1 mA
High Noise Immunity Characteristic of CMOS Devices
NLV Prefix for Automotive and Other Applications Requiring
Unique Site and Control Change Requirements; AEC−Q100
Qualified and PPAP Capable
These are Pb−Free Devices

Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of
these limits are exceeded, device functionality should not be assumed, damage may occur and
reliability may be affected.
This device contains protection
circuitry to guard against damage
due to high static voltages or electric
fields. However, precautions must
be taken to avoid applications of any
voltage higher than maximum rated
voltages to this high−impedance cir-
cuit. For proper operation, Vin and
Vout should be constrained to the
range GND v (Vin or Vout) v VCC.
Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or VCC).
Unused outputs must be left open.
