Classic precision timer IC 用于 monostable and astable multivibrator circuits, 4.5–16V supply, SOIC-8.
The NE555 is a precision timing circuit capable of producing accurate time delays or oscillation. In the time-delay or monostable mode, the timed interval is controlled by a single external 电阻器 and 电容器. In the astable mode, the frequency and duty cycle are accurately controlled with two external 电阻器s and a single 电容器. Key 特性: - Timing from microseconds to hours - Operates in astable or monostable mode - Supply voltage: 4.5V to 16V - 输出电流: 200mA source or sink - Temperature stability: 0.005%/°C typical - Compatible with TTL and CMOS logic - 封装: SOIC-8 表面贴装
