Data Function Description
0
No timer
1
On-delay timer Turning an input signal ON starts the on-delay timer. When the period specified
by the timer has elapsed, an output signal turns ON.
Turning the input signal OFF turns the output signal OFF.
2
Off-delay timer Turning an input signal ON turns an output signal ON.
Turning the input signal OFF starts the off-delay timer. When the period specified
by the timer has elapsed, the output signal turns OFF.
3
One-shot pulse output Turning an input signal ON issues a one-shot pulse whose length is specified by
the timer.
4
Retriggerable timer Turning an input signal ON issues a one-shot pulse whose length is specified by
the timer.
If an input signal is turned ON again during the preceding one-shot pulse length,
however, the logic circuit issues another one-shot pulse.
5
Pulse train output If an input signal turns ON, the logic circuit issues ON and OFF pulses (whose
lengths are specified by the timer) alternately and repeatedly. This function is used
to flash a luminescent device.
The operation schemes for individual timers are shown below.
