TI NE555DR

555 型，计时器/振荡器（单路）100kHz4.5V ~ 16V0°C ~ 70°C8-SOIC（0.154"，3.90mm 宽）表面贴装型

Overview

These devices are precision timing circuits capable of producing accurate time delays or oscillation. In the time-delay or mono-stable mode of operation, the timed interval is controlled by a single external resistor and capacitor network. In the a-stable mode of operation, the frequency and duty cycle can be controlled independently with two external resistors and a single external capacitor.

The output circuit is capable of sinking or sourcing current up to 200 mA. Operation is specified for supplies of 5V to 15V. With a 5-V supply, output levels are compatible with TTL inputs.
