The LM556CM is a Dual Timer feature normally on and normally off output. The LM556 dual-timing circuit is a highly-stable controller and capable of producing accurate time delays or oscillation. The LM556 device is a dual-timing version of the LM555 device. 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.
● 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%/°C
● Green product and no Sb/Br
●Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
