MOTOROLA SEMICONDUCTOR TECHNICAL DATA 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. 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 16 MC74HC151 N SUFFIX PLASTIC PACKAGE CASE 648–08 1 16 1 D SUFFIX SOIC PACKAGE CASE 751B–05 ORDERING INFORMATION MC74HCXXXN MC74HCXXXD Plastic SOIC PIN ASSIGNMENT D3 D2 D1 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 VCC D4 D5 D6 D7 A0 A1 A2 LOGIC DIAGRAM 4 3 2 1 5 Y DATA OUTPUTS 6 Y A2 X L L L L H H H H D0 Y D0 D1 D2 DATA INPUTS D3 Y STROBE GND D4 15 D5 14 D6 13 D7 12 A0 11 10 A1 A2 9 7 PIN 16 = VCC PIN 8 = GND FUNCTION TABLE Inputs A1 X L L H H L L H H A0 X L H L H L H L H Strobe H L L L L L L L L Outputs Y L D0 D1 D2 D3 D4 D5……
