TECHNICAL DATA
IW4541B
Programmable Timer
High-Performance Silicon-Gate CMOS
The IW4541B 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
has been selected) changes from a low to a high state after 2N-1 counts and

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
