CD4541B datasheet


The CD4541B 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 transitions and can also be reset via the MASTER RESET input.

Function Diagram



1. Low Symmetrical Output Resistance, Typically 100Ω at VDD = 15V
2. Built-In Low-Power RC Oscillator
3. Oscillator Frequency Range : DC to 100kHz
4. External Clock (Applied to Pin 3) can be Used Instead of Oscillator
5. Operates as 2N Frequency Divider or as a Single-Transition Timer
6. Q/Q Select Provides Output Logic Level Flexibility
7. AUTO or MASTER RESET Disables Oscillator During Reset to Reduce Power Dissipation
8. Operates With Very Slow Clock Rise and Fall Times
