LND555
PRECISION TIMING CIRCUIT
GENERAL DESCRIPTION
The LND555 is a monolithic timing circuit
capable of producing accurate time delays or
oscillation. In the time delay 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 may be independently controlled with
two external resistors and a single external
capacitor.
FEATURES
• Timing from Microseconds to hours
• Astable or Monostable Operation
• Adjustable Duty Cycle
• TTL-Compatible Output Can Sink or
Source UP to 200mA
• Temperature Stability of 0.005% per °C
• Direct Replacement for Signetics
