LM556CM Datasheet

Timers & Support Products


The LM556CM Dual timing circuit is a highly stable controller capable of producing accurate time delays or oscillation. The 556 is a dual 555. Timing is provided by an external resistor and capacitor for each timing function. The two timers operate independently of each other sharing only VCC and ground. The circuits may be triggered and reset on falling waveforms. The output structures may sink or source 200mA. LM556CM Features • Direct replacement for SE556/NE556• Timing from microseconds through hours• Operates in both astable and monostable modes• Replaces two 555 timers• Adjustable duty cycle• Output can source or sink 200mA• Output and supply TTL compatible• Temperature stability better than 0.005% per °C• Normally on and normally off output LM556CM Applications • Precision timing• Pulse generation• Sequential timing• Time delay generation• Pulse width modulation• Pulse position modulation• Linear ramp generator
