2 / 18 page  NE555,SA555,SE555 PRECISION TIMERS www.artschip.com 2 FUNCTION TABLE RESET TRIGGER VOLTAGE THRESHOLD VOLTAGE OUTPUT DISCHARGE SWITCH Low Irrelevant Irrelevant Low On High <1/3 VDD Irrelevant High Off High >1/3 VDD >2/3 VDD Low On High >1/3 VDD <2/3 VDD As previously established Voltage levels shown are nominal. Function block diagram Pin numbers shown are for the D,JG,P,PS,and PW packages. NOTE A: RESET can override TRIG, which can override THRES. Absolute maximum ratings over operating free-air temperature range (unless otherwise note) † Supply voltage, Vcc (see Note 1)…………………………………………………………………………………………………18V Input voltage (CONT, RESET, THRES, and TRING)…………………………………………………………………………….Vcc Output Current………………………………………………………………………………………………………………… ±225mA Package thermal impedance, ӨJA (see Notes 2 and 3): D package………………………………………………………97℃/W P package……………………………………………………….85℃/W PS package………………………………………………………95℃/W PW package……………………………………………………..149℃/W Package thermal impedance, ӨJC (see Notes 4 and 5): FK package…………………………………………………….5.61℃/W JG package…………………………………………………….14.5℃/W Operating virtual junction temperature, TJ………………………………………………………………………………………..150℃ Case temperature for 60 seconds: FK package…………………………………………………………………………………260℃ Lead temperature 1,6mm (1/16inch) from case for 60 seconds: JG package………………………………………………...300℃ Storage temperature range, Tstg…………………………………………………………………………………………-65℃ to 150℃ †Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. Notes: 1. All voltage values are with respect to GND. 2. Maximum power dissipation is a function of TJ(max). ӨJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD=(TJ(max)-TA)/ ӨJA. Operating at the absolute maximum TJ of 150℃ can affect reliability. 3. The package thermal impedance is calculated in accordance with JESD 51-7. 4. Maximum power dissipation is a function of TJ(max), ӨJC, and TC. The maximum allowable power dissipation at any allowable case temperature is PD=(TJ(max)-Tc)/ ӨJA. Operating at the absolute maximum TJ of 150℃ can affect reliability. 5. The package thermal impedance is calculated in accordance with MIL-STD-883. |
