The LMC555 is a highly stable timer for use in

precision timing and oscillator applications. As timer

(monostable), the device is capable of producing

accurate time delays from microseconds through hours

using x1 capacitor and x1 resistor. As oscillator

(astable), the device can maintain an accurately

controlled free running frequency + duty cycle with x2

external resistors and x1 capacitor. The LMC555 may

be triggered by the falling edge of the waveform signal.

Device output can source or sink up to 200mA current

and drive TTL/CMOS circuits. The LMC555 is a

CMOS upgraded version of the popular bipolar 555

timer series and is drop-in compatible for most legacy

555 applications. The device also directly replaces

TLC555 and ICM7555.
