8-Input Data
Selector/Multiplexer
HighPerformance SiliconGate 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 3state outputs.
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
A
High Noise Immunity Characteristic of CMOS Devices
In Compliance with the Requirements Defined by JEDEC Standard
No. 7A
Chip Complexity: 132 FETs or 33 Equivalent Gates

NOTE: Information on typical parametric values can be found in Chapter 2 of the Motorola HighSpeed CMOS Data Book (DL129/D).
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 highimpedance 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.

PIN DESCRIPTIONS
INPUTS
D0, D1,
...
, D7 (Pins 4, 3, 2, 1, 15, 14, 13, 12)
Data inputs. Data on any one of these eight binary inputs
may be selected to appear on the output.
CONTROL INPUTS
A0, A1, A2 (Pins 11, 10, 9)
Address inputs. The data on these pins are the binary ad-
dress of the selected input (see the Function Table).
Strobe (Pin 7)
Strobe. This input pin must be at a low level for the se-
lected data to appear at the outputs. If the Strobe pin is high,
the Y output is forced to a low level and the Y output is forced
to a high level.
OUTPUTS
Y, Y (Pins 5, 6)
Data outputs. The selected data is presented at these pins
in both true (Y output) and complemented (Y output) forms.
