| SN74LS14 Schmitt Triggers Dual Gate/Hex Inverter The SN74LS14 contains logic gates / inverters which accept standard TTL input signals and provide standard TTL output levels. They are capable of transforming slowly changing input signals into sharply defined, jitter-free output signals. Additionally, they have greater noise margin than conventional inverters. Each circuit contains a Schmitt trigger followed by a Darlington level shifter and a phase splitter driving a TTL totem pole output. The Schmitt trigger uses positive feedback to effectively speed-up slow input transitions, and provide different input threshold voltages for positive and negative-going transitions. This hysteresis between the positive-going and negative-going input thresholds (typically 800 mV) is determined internally by resistor ratios and is essentially insensitive to temperature and supply voltage variations. http://onsemi.com LOW POWER SCHOTTKY LOGIC AND CONNECTION DIAGRAMS VCC 14 13 SN74LS14 12 11 10 9 8 14 1 PLASTIC N SUFFIX CASE 646 1 2 3 4 5 6 7 GND 14 1 GUARANTEED OPERATING RANGES Symbol VCC TA IOH IOL Parameter Supply Voltage Operating Ambient Temperature Range Output Current - High Output Current - Low Min 4.75 0 Typ 5.0 25 Max 5.25 70 - 0.4 8.0 Unit V C SOIC D SUFFIX CASE 751A ORDERING INFORMATION mA mA Device SN74LS14N SN74LS14D Package 14 Pin DIP 14 Pin Shipping 2000 Units/Box 2500/Tape & Reel (c) Semiconductor Components Industries, LLC, 1999 1 December, 1999 - Rev. 0 Publication Order Number: SN74LS14/D SN74LS14 DC CHARACTERISTICS OVER OPERATING TEMPERATURE RANGE (unless otherwise specified) Limits Symbol VT+ VT- VT+ - VT- VIK VOH VO OL IT+ IT- IIH IIL IOS Parameter Positive-Going Threshold Voltage Negative-Going Threshold Voltage Hysteresis Input Clamp Diode Voltage Output HIGH Voltage Output LOW Voltage 0.35 Input Current at Positive-Going Threshold Input Current at Negative-Going Threshold Input HIGH Current 0.1 Input LOW Current Short Circuit Current (Note 1) Power Supply Current ICC Total, Output HIGH , 12 Total, Output LOW Note 1: Not more than one output should be shorted at a time, nor for more than 1 second. 21 - 20 8.6 - 0.4 -100 16 mA VCC = MAX - 0.14 - 0.18 1.0 20 0.5 V mA mA A mA mA mA 2.7 Min 1.5 0.6 0.4 0.8 - 0.65 3.4 0.25 0.4 - 1.5 Typ Max 2.0 1.1 Unit V V V V V V Test Conditions VCC = 5.0 V VCC = 5.0 V VCC = 5.0 V VCC = MIN, IIN = - 18 mA VCC = MIN, IOH = - 400 A, VIN = VIL VCC = MIN, IOL = 4.0 mA, VIN = 2.0 V VCC = MIN, IOL = 8.0 mA, VIN = 2.0 V VCC = 5.0 V, VIN = VT+ VCC = 5.0 V, VIN = VT- VCC = MAX, VIN = 2.7 V VCC = MAX, VIN = 7.0 V VCC = MAX, VIN = 0.4 V VCC = MAX, VOUT = 0 V AC CHARACTERISTICS (TA = 25C) Symbol tPLH tPHL Parameter Propagation Delay, Input to Output Propagation Delay, Input to Output Max 22 22 Unit ns ns Test Conditions VCC = 5.0 V CL = 15 pF 3V VIN 0V tPHL tPLH 1.6 V 0.8 V VOUT 1.3 V 1.3 V Figure 1.
