NOTE: This circuit is designed to use the on−chip oscillation function. The oscillator frequency is determined 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.: standby condition). After RESET goes low, the output remains low for 2
part times out, the output again goes high.
