TECHNICAL DATA ILC555QD CMOS Automotive purpose timer The ILC555 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 ILC555 is stable controller capable of producing accurate time delays of frequencies. ORDERING INFORMATION ILC555QDT SOP TA = -40 to 125 C 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 AEC 100 Qualified PIN ASSIGNMENT 01 08 TRIGGER 02 07 DISCHARGE OUTPUT 03 RESET 04 GND ILC555N VCC 06 THRESHOLD 05 CONTROL VOLTAGE 2015, August, ver.00 ILC555QDT TRUTH TABLE THRESHOLD TRIGGER RESET OUTPUT DISCHARGE X X L L ON > 2/3VCC > 1/3VCC H L ON < 2/3VCC > 1/3VCC H STABLE STABLE X < 1/3VCC H H OFF MAXIMUM RATINGS AND RECOMMENDED OPERATING CONDITIONS Parameter, unit Recommended operating conditions Maximum ratings Value Value Symbol min max min max 2.0 15.0 0 18.0 IO - 20 - 100 VTH, VTRIG, VRST - - -0.3 VCC+0.3 Power Dissipation, mW PD - - - 200 Operating Temperature,С TOPR -40 125 -40 125 Storage Temperature, С TSTG - - -65 150 Lead Temperature, 1 mm from Case for 10 Seconds, С TSOLDER - - Supply Voltage, V Output Current, mА Input Voltage, V VCC 260 * Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.
