What is the Electronic component - CD4541B?

What's CD4541B?

CD4541B is one of the electronic components that also called a programmable timer which consists of a 16-stage binary counter, an oscillator that is controlled by external R-C components, 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. The output from this timer is the Q or 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.

What are the features of CD4541B?

CD4541B has many features and the following lists out the main features of it.

* Low Symmetrical Output Resistance, Typically 100 at VDD = 15V

* Built-In Low-Power RC Oscillator

* Operates as 2N Frequency Divider or as a SingleTransition Timer

* Q/Q Select Provides Output Logic Level Flexibility

* AUTO or MASTER RESET Disables Oscillator During Reset to Reduce Power Dissipation

* Operates With Very Slow Clock Rise and Fall Times

* Symmetrical Output Characteristics

* 100% Tested for Quiescent Current at 20V

* 5V, 10V, and 15V Parametric Ratings

* Meets All Requirements of JEDEC Standard No. 13B, "Standard Specifications for Description of `B' Series CMOS Devices"

* Capable of Driving Six Low Power TTL Loads, Three Low-Power Schottky Loads, or Six HTL Loads Over the Rated Temperature Range

* Oscillator Frequency Range . . . . . . . . . . DC to 100kHz * External Clock (Applied to Pin 3) can be Used Instead of Oscillator

By the way, be caution about CD4541B is sensitive to electrostatic discharge, you should follow proper IC Handling Procedures.
