74HC14D

TIGER ELECTRONIC CO.,LTD High-Speed Cmos Logic Hex Inverting Schmitt Trigger 74HC14N / D The 74HC14 is useful to “square up” slow input rise and fall times. Due to the hysteresis voltage of the Schmitt trigger, the 74HC14 finds applications in noisy environments. 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 74HC14N DIP 74HC14D SOP TA = -55° to 125° C for all packages LOGIC DIAGRAM PIN ASSIGNMENT PIN 14 =VCC PIN 7 = GND FUNCTION TABLE Inputs A L H Output Y H L 74HC14 MAXIMUM RATINGS* Symbol Parameter Value VCC VIN VOUT IIN IOUT ICC PD 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+ -0.5 to +7.0 -1.5 to VCC +1.5 -0.5 to VCC +0.5 ±20 ±25 ±50 750 500 Tstg Storage Temperature -65 to +150 TL Lead Temperature, 1 mm from Case for 10 Seconds (Plastic DIP or SOIC Package) 260 *Maximum Ratings are those values beyond which damage to the device may occur.
