Timers
The MC1455 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 freerunning
frequency and the duty cycle are both accurately controlled with two
external resistors and one capacitor. The circuit may be triggered and
reset on falling waveforms, and the output structure can source or sink
up to 200 mA or drive TTL circuits.

Test circuit for measuring DC parameters (to set output and measure
parameters):
a) When VS w 2/3 VCC, VO is low.
b) When VS v 1/3 VCC, VO is high.
c) When VO is low, Pin 7 sinks current. To test for Reset, set VO
c) high, apply Reset voltage, and test for current flowing into Pin 7.
c) When Reset is not in use, it should be tied to VCC.
