Overview

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 IW4541BN Plastic has been selected) changes from a low to a high s...
