SL74HCT14 Datasheet | System Logic Semiconductor

Hex Schmitt-Trigger Inverter High-Performance Silicon-Gate CMOS The SL74HCT14 may be used as a level converter for interfacing TTL or NMOS outputs to high-speed CMOS inputs. The SL74HCT14 is identical in pinout to the LS/ALS14. The SL74HCT14 is useful to “square up” slow input rise and fall times. Due to the hysteresis voltage of the Schmitt trigger, the SL74HCT14 finds applications in noisy environments. - TTL/NMOS-patible Input Levels. - Outputs Directly Inferface to CMOS, NMOS and TTL. - Operating Voltage Range: 4.5 to 5.5 V - Low Input Current: 1.0 µA ORDERING INFORMATION SL74HCT14N Plastic SL74HCT14D SOIC TA = -55° to 125° C for all packages LOGIC DIAGRAM PIN ASSIGNMENT FUNCTION TABLE Inputs A L H Output Y H L PIN 14 =VCC PIN 7 = GND System Logic Semiconductor MAXIMUM RATINGS - Symbol VCC VIN VOUT IIN IOUT ICC PD Tstg 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 m A m A m A m W °C °C Maximum Ratings are those values beyond which damage to the device may occur.
