TECHNICAL DATA
KK4541B
Programmable Timer
High-Performance Silicon-Gate CMOS
The KK4541B programmable timer consists of a 16-stage binary
counter, an oscillator that is controlled by external R-C components (2
resistors and a capacitor), an automatic power-on reset circuit, and output
control logic. The counter increments on positive-edge clock transitons
and can also be reset via the MASTER RESET input.
The output from this timer is the Q or not Q output from the 8th, 10th,
13th, or 16th counter stage. The desired stage is chosen using time-select
inputs A and B. The output is available in either of two modes selectable
via the MODE input, pin 10. When this MODE input is a logic “1”,the
output will be a continuous square wave having a frequency equal to the
oscillator frequency divided by 2N. With the MODE input set to logic ”0”
ORDERING INFORMATION
and after a MASTER RESET is initiated, the output (assuming Q output
KK4541BN Plastic
has been selected) changes from a low to a high state after 2N-1 counts and
KK4541BD SOIC
remains in that state until another MASTER RESET pulse is applied or
TA = -55° to 125° C for all packages
the MODE input is set to a logic “1”.
Timing is initialized by setting the AUTO RESET input (pin 5) to
logic “0”and turning power on. If pin 5 is set to logic “1”, the AUTO RESET circuit is disabled and counting will not
start untill after a positive MASTER RESET pulse is applied and returns to a low level. The AUTO RESET consumes
an appreciable amount of power and should not be used if low-power operation is desired. For reliable automatic
power-on reset, VCC should be greater than 5V.
• Operating Voltage Range: 3.0 to 18 V
• Maximum input current of 1 µA at 18 V over full package-temperature range; 100 nA at 18 V and 25°C
• Noise margin (over full package temperature range):
1.0 V min @ 5.0 V supply
2.0 V min @ 10.0 V supply
2.5 V min @ 15.0 V supply

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, VIN and VOUT should be constrained to the range GND≤(VIN or
VOUT)≤VCC.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused
outputs must be left open.
