RTC clock synchronization buffer driver delay chip

Type: 555 type, timer/oscillator (single channel) Frequency: 1.8MHz Operating voltage: 1V~15V Operating current: 360μA

SA555 Precision Timer

Industrial-grade low-power real-time clock chip with trickle current charging capability

The MC1455 monolithic timer circuit is a very stable controller capable of generating accurate time delays or oscillations. Additional terminals are available for trigger or reset if required. In time-delay mode, the timing is precisely controlled by an external resistor and capacitor. For stable operation as an oscillator, both the idle frequency and duty cycle are accurately controlled with two external resistors and a capacitor. The circuit can be toggled and reset on falling waveforms and the output structure can source/sink up to 200 mA or drive a TTL circuit.
