NTE74HC14

NTE74HC14 Integrated Circuit TTL − High Speed CMOS, Hex Schmitt Trigger Inverter Description: The NTE74HC14 is a hex Schmitt Trigger inverter in a 14−Lead plastic DIP type package and is useful to “square−up” slow input rise and fall times. Due to hysteresis voltage of the Schmitt Trigger, the NTE74HC14 finds applications in noisy environments. The NTE74HC14 is identical in pinout to the ’LS14, LS04 and the HC04 and the device inputs are compatible with Standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. Features: D Output Drive Capability: 10 LSTTL Loads D Outputs Directly Interface to CMOS, NMOS, and TTL D Operating Voltage range: 2V to 6V D Low Input Current: 1.0μA D High Noise Immunity Characteristics of CMOS Devices Absolute Maximum Ratings: (Note 1, Note 2) Supply Voltage, VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −0.5 to +7.0V DC Input Voltage, VIN . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −0.5 to VCC +0.5V DC Output Voltage, VOUT . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −0.5 to VCC +0.5V Clamp Diode Current, IIK, IOK . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ±20mA DC Output Current (Per Pin), IOUT . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ±25mA DC VCC or GND Current (Per Pin), ICC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ±50mA Power Dissipation (Note 3), PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 600mW Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −65°C to +150°C Lead Temperature (During Soldering, 10sec), TL . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . +260°C Note 1. Stresses exceeding the Absolute Maximum Ratings may damage the device. The device may not function or be operable above the Recommended Operating Conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the Recommended Operating Conditions may effect device reliability. The Absolute Maximum Ratings are stress ratings only. Note 2. Unless otherwise specified, all voltages are referenced to GND. Note 3. Power Dissipation temperature derating: 12mW/°C from +65°C to +85°C. Recommended Operating Conditions: Parameter Symbol Min Max Unit VCC 2.0 6.0 V VIN, VOUT 0 VCC V Operating Temperature Range TA −55 +125 °C Input Rise or Fall Times (Note 4) VCC = 2.0V tr, tf 0 No Limit ns VCC = 4.5V 0 No Limit ns VCC = 6.0V 0 No Limit ns Supply Voltage DC Input or Output Voltage Note 4.
