SL74HC151

SL74HC151 8-Input Data Selector/Multiplexer High-Performance Silicon-Gate CMOS The SL74HC151 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 • Low Input Current: 1.0 µA • High Noise Immunity Characteristic of CMOS Devices ORDERING INFORMATION SL74HC151N Plastic SL74HC151D SOIC TA = -55° to 125° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs A2 X L L PIN 16 =VCC PIN 8 = GND L L H H H H 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 D6 D7 Y H D0 D1 D2 D3 D4 D5 D6 D7 D0,D1...D7=the level of the respective D input X = don’t care SLS System Logic Semiconductor SL74HC151 MAXIMUM RATINGS * Symbol VCC VIN VOUT IIN IOUT ICC PD T stg TL * Parameter DC Supply Voltage (Referenced to GND) DC Input Voltage (Referenced to GND) DC Output Voltage (Referenced to GND) DC Input Current, per Pin DC Output Current, per Pin DC Supply Current, VCC and GND Pins Power Dissipation in Still Air, Plastic DIP+ SOIC Package+ Storage Temperature Lead Temperature, 1 mm from Case for 10 Seconds (Plastic DIP or SOIC Package) Value -0.5 to +7.0 -1.5 to VCC +1.5 -0.5 to VCC +0.5 ±20 ±25 ±50 750 500 -65 to +150 260 Unit V V V mA mA mA mW °C °C Maximum Ratings are those values beyond which damage to the device may occur.

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 a nd VOUT 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 V ). CC Unused outputs must be left open.
