NTE74HCT14

NTE74HCT14 & NTE74HCT14T Integrated Circuit TTL − High Speed CMOS, Hex Inverting Schmitt Trigger Description: The NTE74HCT14 (14−Lead DIP) and NTE74HCT14T (SOIC−14) are hex inverting Schmitt trigger devices that utilizes advanced silicon−gate CMOS technology to achieve the low power dissipation and high noise immunity of standard CMOS, as well as the capability to drive 10 LS−TTL loads. Inputs are protected from damage due to static discharge by internal diode clamps to VCC and GND. Features: D Propagation Delay: 13ns (typ) D Wide Power Supply Range: 4.5V to 5.5V D Low Quiescent Current: 10μA (max) D Low Input Current: 1μA (max) D Fanout of 10 LS−TTL Loads D Typical Hysteresis Voltage: 0.6V at VCC = 4.5V D TTL, LS Pinout and Input Threshold Compatible Absolute Maximum Ratings: (Note 1, Note 2) Supply Voltage, VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −0.5 to +7.0V DC Input Voltage, VIN . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −1.5 to VCC +1.5V 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 Typ Max Unit VCC 4.5 − 5.5 V VIN, VOUT 0 − VCC V TA −40 − +85 °C Supply Voltage DC Input or Output Voltage Operating Temperature Range (VCC = 5.5V unless otherwise specified) DC Electrical Characteristics: TA = +25°C Parameter Symbol Positive−Going Threshold Voltage VT+ Test Conditions Minimum Maximum Negative−Going Threshold Voltage VT− Minimum Maximum Hysteresis Voltage VH Minimum Maximum Minimum High Level Output Voltage Minimum Low Level Output Voltage VOH VOL VIN = VIH or VIL VIN = VIH VCC = 4.5V VCC = 4.5V VCC = 4.5V VCC = 4.5V VCC = 4.5V VCC = 4.5V Typ TA = −40° to +85°C Guaranteed Limits Unit 1.5 1.2 1.2 V 1.7 1.4 1.4 V 1.5 1.9 1.9 V 1.7 2.1 2.1 V 0.9 0.5 0.5 V 1.0 0.6 0.6 V 0.9 1.2 1.2 V 1.0 1.4 1.4 V 0.6 0.4 0.4 V 0.7 0.4 0.4 V 0.6 1.4 1.4 V 0.7 1.5 1.5 V VCC −0.1 V |IOUT| = 20μA, VCC = 4.5V VCC VCC −0.1 |IOUT| = 4.0mA, VCC = 4.5V 4.2 3.98 3.84 V |IOUT| = 4.8mA, 5.2 4.98 4.84 V |IOUT| = 20μA, VCC = 4.5V 0 0.1 0.1 V |IOUT| = 4.0mA, VCC = 4.5V 0.2 0.26 0.33 V |IOUT| = 4.8mA 0.2 0.26 0.33 V Maximum Input Current IIN VIN = VCC or GND, VIH or VIL − ±0.1 ±1.0 μA Maximum Quiescent Supply Current ICC VIN = VCC or GND, IOUT = 0μA − 1.0 10 μA VIN = 2.4V or 0.5V − 2.4 2.4 mA AC Electrical Characteristics: (VCC = 5V, tr = tf = 6ns, CL = 15pF, TA = +25°C unless otherwise specified) Parameter Maximum Propagation Delay Symbol Test Conditions tPLH, tPHL Typ Guaranteed Limits Unit 10 18 ns AC Electrical Characteristics: (VCC = 5V ±10%, tr = tf = 6ns, CL = 50pF unless otherwise specified) TA = +25°C Parameter Symbol Test Conditions Typ TA = −40° to +85°C Guaranteed Limits Unit Maximum Propagation Delay tPLH, tPHL − 20 25 ns Maximum Output Rise and Fall Time tTHL, tTLH 9 15 19 ns − 25 − pF 5 10 10 pF Power Dissipation Capacitance CPD Maximum Input Capacitance CIN Per Gate, Note 4 Note 4.
