SE555N - General-purpose single bipolar timer

Download the SE555N datasheet PDF. This datasheet also covers the SE555 variant, as both devices belong to the same general-purpose single bipolar timer family and are provided as variant models within a single manufacturer datasheet.

Description

The NE555, SA555, and SE555 monolithic timing circuits are highly stable controllers capable of producing accurate time delays or oscillation.

In the time delay mode of operation, the time is precisely controlled by one external resistor and capacitor.

Features

  • Low turn-off time.
  • Maximum operating frequency greater than 500 kHz.
  • Timing from microseconds to hours.
  • Operates in both astable and monostable modes.
  • Output can source or sink up to 200 mA.
  • Adjustable duty cycle.
  • TTL compatible.
  • Temperature stability of 0.005% per °C.

NE555 SA555 - SE555 General-purpose single bipolar timers Features ■ Low turn-off time ■ Maximum operating frequency greater than 500 kHz ■ Timing from microseconds to hours ■ Operates in both astable and monostable modes ■ Output can source or sink up to 200 mA ■ Adjustable duty cycle ■ TTL compatible ■ Temperature stability of 0.005% per °C Description The NE555, SA555, and SE555 monolithic timing circuits are highly stable controllers capable of producing accurate time delays or oscillation. In the time delay mode of operation, the time is precisely controlled by one external resistor and capacitor. For a stable operation as an oscillator, the free running frequency and the duty cycle are both accurately controlled with two external resistors and one capacitor.
