MC14536B
Programmable Timer
The MC14536B programmable timer is a 24−stage binary ripple
counter with 16 stages selectable by a binary code. Provisions for an
on−chip RC oscillator or an external clock are provided. An on−chip
monostable circuit incorporating a pulse−type output has been
included. By selecting the appropriate counter stage in conjunction
with the appropriate input clock frequency, a variety of timing can be
achieved.

Stresses exceeding those listed in the Maximum Ratings table may damage the
device. If any of these limits are exceeded, device functionality should not be
assumed, damage may occur and reliability may be affected.
1. Temperature Derating: “D/DW” Packages: –7.0 mW/_C from 65_C to 125_C
This device contains protection circuitry to guard against damage due to high
static voltages or electric fields. However, precautions must be taken to avoid
applications of any voltage higher than maximum rated voltages to this
high−impedance circuit. For proper operation, V
in
and V
out
should be constrained
to the range V
SS
≤ (V
in
or V

) ≤ V
DD
.
Unused inputs must always be tied to an appropriate logic voltage level
(e.g., either V
SS
or V
DD
). Unused outputs must be left open.
