Operating voltage: 5~12V Product Description NE555 Pulse Generator is precision timing circuits capable of producing accurate time delays or oscillation. In the time-delay or monostable mode of operation, the timed interval is controlled by a single external resistor and capacitor network. In the astable mode of operation, the frequency and duty cycle can be controlled independently with two external resistors and a single external capacitor. The threshold and trigger levels normally are two-thirds and one-third, respectively, of VCC. These levels can be altered by use of the control-voltage terminal. When the trigger input falls below the trigger level, the flip-flop is set, and the output goes high. If the trigger input is above the trigger level and the threshold input is above the threshold level, the flip-flop is reset and the output is low. The reset (RESET) input can override all other inputs and can be used to initiate a new timing cycle. When RESET goes low, the flip-flop is reset, and the output goes low. When the output is low, a low-impedance path is provided between discharge (DISCH) and ground. The output circuit is capable of sinking or sourcing current up to 200 mA.

Operation is specified for supplies of 5 V to 15 V. With a 5-V supply, output levels are compatible with TTL inputs. 1 Channel DC 3V/ 3.3V Power Relay Module 3V Relay Switch Module SIP-1A05 Reed Switch Relay 5V SIP-1A05 Reed Relay Switch Raspberry Pi Relay Module HAT Expansion Board Three Channel Power Relay USB Serial Port Control Relay Module Sturdy Durable Lightweight USB Relay ESP8266 ESP-12F WiFi Single Relay Module ESP DC5-80V Wireless Controller Relay Add to Cart Add to Cart Add to Cart Add to Cart Add to Cart Price $ 9.95 $9. 95 $ 7.95 $7. 95 $ 19.75 $19. 75 $ 8.95 $8. 95 $ 17.95 $17. 95 price
