8-Input Data Selector/
Multiplexer with
3-State Outputs
HighPerformance SiliconGate CMOS
The MC54/74HC251 is identical in pinout to the LS251. 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 Output Enable pin must be a
low level for the selected data to appear at the outputs. If Output
Enable is high, both the Y and the Y outputs are in the
highimpedance state. This 3state feature allows the HC251 to be
used in busoriented systems.
The HC251 is similar in function to the HC251 which does not have
3state 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
These are PbFree Devices
