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 AiP555 is a stable controller capable of producing accurate time delays or frequencies. In the one shot mode, the pulse width of each circuit is precisely controlled by one external resistor and capacitor. For astable operation as an oscillator, the free running frequency and the duty cycle are both accurately controlled by two external resistors and one capacitor. Unlike the regular bipolar 555 device, the Control Voltage terminal need not be decoupled with a capacitor. The circuits are triggered and reset on falling (negative) waveforms, and the output inverter can source or sink currents large enough to drive TTL loads, or provide minimal offsets to drive CMOS loads. 2、Block Diagram And Pin Description i-c or 2.1、Block Diagram NOTE: UNUSED INPUTS SHOULD BE CONNECTED TO APPROPRIATE VOLTAGE FROM TRUTH TABLE 2.2、Pin Configurations GND 1 /TRIGGER 2 OUTPUT 3 /RESET 4 AiP555 8 VDD 7 DISCHARGE 6 THRESHOLD 5 CONTROL VOLTAGE Address：Building B4,NO.777,Jianzhu Road,Binhu Distrct,Wuxi City,Jiangsu Province http://www.i-core. cn P.C：214072 2/ 11 VER：2017-11-A1 Tab: 835-12 Wuxi I-CORE Electronics Co., Ltd. rev:B2 Number: AiP555-AX-BJ-452 2.3、Pin Description Pin No. 1 Pin Name GND Description Ground 2 3 4 /TRIGGER OUTPUT /RESET Trigger Voltage Input Voltage Signal Output Reset Voltage Input 5 6 CONTROL VOLTAGE THRESHOLD 7 DISCHARGE 8 VDD Control Voltage Input Threshold Voltage Input Discharge Switch 3、Electrical Parameter 3.1、 Absolute Maximum Ratings e Power (Tamb=25℃, All voltage referenced to Vss, unless otherwise specified) Symbol VDD Conditions Value +18 Unit V or Characteristic Power Supply Voltage Trigger， Control Input Voltage VIN Output Current -0.3～VDD+0.3 V IOUT 100 mA Operating Temperature Topr -25～85 ℃ Storage Temperature Tstg -55～125 ℃ Power Dissipation Soldering Temperature PD TL 500 245 mW ℃ Voltage, Threshold, Reset i-c 10s 3.2、Electrical Characteristics (Tamb=25℃, unless otherwise specified) Parameter Symbol Conditions Static Supply Current IDD Min.
