CD4541BM CD4541BC Programmable Timer
General Description
The CD4541B 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 features of
the power-on reset circuit are first no additional static pow-
er consumption and second the part functions across the
full voltage range (3V–15V) whether power-on reset is en-
abled 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 network The
16-stage counter divides the oscillator frequency by any of 4
digitally controlled division ratios
Features
Y Available division ratios 28 210 213 or 216
Y Increments on positive edge clock transitions
Y Built-in low power RC oscillator (g2% accuracy over
temperature range and g10% supply and g3% over
processing k 10 kHz)
Y Oscillator frequency range DC to 100 kHz
Y Oscillator may be bypassed if external clock is available
(apply external clock to pin 3)
Y Automatic reset initializes all counters when power
turns on
Y External master reset totally independent of automatic
reset operation
Y Operates at 2n frequency divider or single transition
timer
Y Q Q select provides output logic level flexibility
Y Reset (auto or master) disables oscillator during reset-
ting to provide no active power dissipation
Y Clock conditioning circuit permits operation with very
slow clock rise and fall times
Y Wide supply voltage range 3 0V to 15V
Y High noise immunity 0 45 VDD (typ )
Y 5V – 10V – 15V parameter ratings
Y Symmetrical output characteristics
Y Maximum input leakage 1 mA at 15V over full tempera-
ture range
Y High output drive (pin 8) min one TTL load

Note 1 ‘‘Absolute Maximum Ratings’’ are those values beyond which the safety of the device cannot be guaranteed Except for ‘‘Operating Temperature Range’’
they are not meant to imply that the devices should be operated at these limits The table of ‘‘Electrical Characteristics’’ provides conditions for actual device
operation
Note 2 VSS e 0V unless otherwise specified
Note 3 IOH and IOL are tested one output at a time
Note 4 CPD determines the no load AC power consumption of any CMOS device For complete explanation see 54C 74C family characteristics application note
