8-INPUT DATA SELECTOR/MULTIPLEXER
High-Performance Silicon-Gate CMOS
The IN74HC151 is identical in pinout to the LS/ALS151. The
device inputs are compatible with standard CMOS outputs; with
pullup resistors, they are compatible with LS/ALSTTL outputs.
The 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.
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 2.0 to 6.0 V
ORDERING INFORMATION
• Low Input Current: 1.0 µA

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 circuit. For proper operation, VIN and
V
OUT should be constrained to the range GND≤(VIN or VOUT)≤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.
