Figure 11. Time Interval Configuration Using On–Chip RC Oscillator and
Reset Input to Initiate Time Interval
(Divide–by–2 Configured)
NOTE: This circuit is designed to use the on–chip oscillation function. The oscillator frequency is deter-
mined by the external R and C components. When power is first applied to the device, Decode Out
initializes to a high state. Because this output is tied directly to the Osc–Inh input, the oscillator is
disabled. This puts the device in a low–current standby condition. The rising edge of the Reset pulse
will cause the output to go low. This in turn causes Osc–Inh to go low. However, while Reset is high,
the oscillator is still disabled (i.e.: standy condition). After Reset goes low, the output remains low
for 2n/2 of the oscillator’s period. After the part times out, the output again goes high.
