| TECHNICAL DATA KKC555 CMOS general purpose timer The KKC555 is CMOS RC timers providing significantly improved performance over the standard SE/NE555 and 355 timers, while at the same time being direct replacements for those devices in most applications. Improved parameters include low supply current, wide operating supply voltage range, low THRESHOLD, TRIGGER and RESET currents, no crowbarring of the supply current during output transitions, higher frequency performance and no requirement to decouple CONTROL VOLTAGE for stable operation. Specifically, the KKC555 is stable controller capable of producing accurate time delays of frequencies. ORDERING INFORMATION KKC555N Plastic KKC555D SOIC TA = -20 to 70 C for all packages. * * * * * * * * Exact equivalent in most cases for SE/NE555. Low Supply Current. High speed operation - 500 kHz guaranteed. Wide operation supply voltage range - 2 to 18 volts. Timing from microseconds through hours. Operates in both astable and monostable modes. Adjustable duty cycle. High output source/sink driver can drive TTL/CMOS PIN ASSIGNMENT GND 01 02 08 VCC TRIGGER OUTPUT RESET 07 DISCHARGE KKC555N 03 04 06 THRESHOLD 05 CONTROL VOLTAGE 1 KKC555 TRUTH TABLE THRESHOLD X > 2/3VCC < 2/3VCC X TRIGGER X > 1/3VCC > 1/3VCC < 1/3VCC RESET L H H H OUTPUT L L STABLE H DISCHARGE ON ON STABLE OFF MAXIMUM RATINGS AND RECOMMENDED OPERATING CONDITIONS Parameter, unit Symbol Recommended operating conditions Value min Supply Voltage, V Output Current, m Input Voltage, V VCC IO VTH, VTRIG, VRST PD TOPR TSTG TSOLDER 2.0 max 18.0 20 min 0 -0.3 Maximum ratings Value max 18.0 100 VCC+0.3 200 85 150 260 Power Dissipation, mW Operating Temperature, Storage Temperature, Lead Temperature, 1 mm from Case for 10 Seconds, -20 - 70 - -20 -65 2 KKC555 DC ELECTRICAL CHARACTERISTICS (Voltages Referenced to GND) Parameter, units Threshold Voltage, V Symbol VTH Test Conditions IOL, IOH VCC, 5.0 min 0.65 VCC 0.60 VCC Trigger voltage, V VTRIG 5.0 0.31 VCC 0.28 VCC 2.0 Reset voltage, V VRST 18.0 2.0 18.0 Control Voltage Lead, V VCV 0.65 VCC 0.60 VCC Output voltage Low, V VOL IOL = 3.2 m IOL = 20 m IOL = 3.2 m IOL = 20 m Output voltage High, V VOH IOH = -0.8 m 5.0 15.0 5.0 15.0 5.0 15.0 5.0 15.0 2.0 Supply Current, A ICC 18.0 2.0 18.0 4.0 14.3 3.5 14.0 200 300 400 600 -20, 70 2510 -20, 70 0.69 VCC 0.80 VCC 0.4 1.0 0.6 1.5 2510 -20, 70 2510 -20, 70 2510 0.2 1.5 -20, 70 0.4 Value max 0.70 VCC 0.80 VCC 0.36 VCC 0.40 VCC 1.0 Temperature, 2510 -20, 70 2510 -20, 70 2510 3 KKC555 AC ELECTRICAL CHARACTERISTICS Parameter, unit Rise (Fall) Time of Output, ns Guaranteed Max Osc Freq, kHz Initial accuracy, % Drift with Temperature, %/ Symbol Test Conditions RL, CL VCC, V Min Value Max Temperature, tTHL, tTLH RL = 10 , CL = 10 pF fMAX Astable Operation 5.0 35 70 500 200 5 75 150 2510 -20, 70 2510 -20, 70 2.018.0 5.0 f RL = 1 - 100 k, CL = 0.1 F f 0.02 0.03 0.06 3 6 -20, 70 Drift with Supply Voltage, %/ 10.0 15.0 5.0 2510 -20, 70 TRIGGER COMPARATOR A THRESHOLD COMPARATOR B Figura 1.
