USA555 - PRECISION TIMERS

Datasheet Summary

Description

The UTC USA555 monolithic timing circuit is a highly stable controller 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.

Features

S.
Astable or monostable operation.
Low turn off time.
Operates in both astable and monostable modes.
Timing from microseconds to hours.
Adjustable duty cycle.
TTL-compatible output can sink or source up to 200mA.

UNISONIC TECHNOLOGIES CO., LTD USA555 LINEAR INTEGRATED CIRCUIT PRECISION TIMERS  DESCRIPTION The UTC USA555 monolithic timing circuit is a highly stable controller 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.
