LM555DGKRG

HANSCHIP semiconductor · Timers / Counters · MSOP-8

LM555DGKRG from HANSCHIP semiconductor, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground (电源地) reference pin for the timer; the datasheet gives no separate limit for this pin.
2 Trig input Trigger input that starts the monostable cycle when the voltage falls to 1/3 VCC, with a trigger input current of 2 µA max at VCC = 15 V (VTRIG = 0 V).
3 Output output Output driver with a recommended output current of ±200 mA (absolute maximum ±220 mA) and typical high-state output of 13.3 V at VCC = 15 V, IL = -100 mA.
4 Reset input Active-low reset input: a low level must be at or below 0.5 V and a high level at or above 1.5 V at VCC = 5 V, with a typical reset current of 0.13 mA at VRESET = 0.4 V and VCC = 15 V.
5 Cont passive Control voltage pin that sets the internal comparator reference, typically 10.0 V at VCC = 15 V and 3.3 V at VCC = 5 V.
6 Thres input Threshold input for the internal comparator, typically 10.0 V at VCC = 15 V and 3.3 V at VCC = 5 V, with a threshold current of 250 nA max at VCC = 15 V.
7 Disch passive Discharge pin driven by the internal discharge transistor, with a saturation voltage of 140 mV typical and 480 mV max at VCC = 15 V and Idis = 15 mA, and an off-state leakage of 100 nA max.
8 VCC power_in Positive supply: the recommended operating range is 4.5 V to 15 V and the absolute maximum supply voltage is 18 V.
