DescriptionThe MC1455DR2 monolithic timing circuit is a highly stable controller capable of producing accurate time delays or oscillation. Additional terminals are provided for triggering or resetting if desired. In the time delay mode, time is precisely controlled by one external resistor and capacitor. For astable operation as an oscillator, the free−running frequency and the duty cycle are both accurately controlled with two external resistors and one capacitor. The MC1455DR2 may be triggered and reset on falling waveforms, and the output structure can source or sink up to 200 mA or drive MTTL circuits.
The feature of the MC1455DR2 are:(1)Direct Replacement for NE555 Timers; (2)Timing from Microseconds through Hours; (3)Operates in Both Astable and Monostable Modes; (4)Adjustable Duty Cycle; (5)High Current Output Can Source or Sink 200 mA; (6)Output Can Drive MTTL; (7)Temperature Stability of 0.005% per °C; (8)Normally ON or Normally OFF Output; (9)Pb-Free Packages are Available.
The absolute maximum ratings of the MC1455DR2 can be summarized as:(1)Power Supply Voltage:+18 Vdc; (2)Discharge Current (Pin 7):200 mA; (3)Power Dissipation (Package Limitation) P1 Suffix, Plastic Package:625mW; (4)Derate above TA = +25°C:5.0mW/°C; (5)D Suffix, Plastic Package:625mW; (6)Derate above TA = +25°C:160°C/W; (7)Operating Temperature Range (Ambient):0 to +70°C; (8)Maximum Operating Die Junction Temperature:+150 °C; (9)Storage Temperature Range:-65 to +150 °C.
The electrical characteristics at TA=25°C of the MC1455DR2 can be summarized as:(1)operating supply voltage range:4.5~16V; (2)trigger current:0.5A; (3)reset voltage:0.4V min 0.7V typ 1.0V max; (4)reset current:0.1mA typ; (5)threshold current:0.1A typ 0.25 A max.If you want to know more information such as the electrical AC characteristics ,please download the datasheet in www.seekdatasheet.com .
