Programmable Timer
General Description
The CD4541BC Programmable Timer is designed with a
16-stage binary counter, an integrated oscillator for use
with an external capacitor and two resistors, output control
logic, and a special power-on reset circuit. The special fea-
tures of the power-on reset circuit are first, no additional
static power consumption and second, the part functions
across the full voltage range (3V–15V) whether power-on
reset is enabled or disabled.
Timing and the counter are initialized by turning on power,
if the power-on reset is enabled. When the power is
already on, an external reset pulse will also initialize the
timing and counter. After either reset is accomplished, the
oscillator frequency is determined by the external RC net-
work. The 16-stage counter divides the oscillator frequency
by any of 4 digitally controlled division ratios.

Oscillator may be bypassed if external clock is available
(apply external clock to pin 3)
Automatic reset initializes all counters when power turns
on
External master reset totally independent of automatic
reset operation
Operates at 2

Q/Q select provides output logic level flexibility
Reset (auto or master) disables oscillator during reset-
ting to provide no active power dissipation
Clock conditioning circuit permits operation with very
slow clock rise and fall times
Wide supply voltage range—3.0V to 15V
High noise immunity—0.45 V
5V–10V–15V parameter ratings
Symmetrical output characteristics
