The desired stage is chosen using time-select inputs A and B (see Frequency Select Table). • Low Symmetrical Output Resistance, Typically 100Ω at VDD = 15V The output is available in either of two modes selectable via the MODE input, pin 10 (see Truth Table). 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” 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 the MODE input is set to a logic “1”. • Built-In Low-Power RC Oscillator • Oscillator Frequency Range . . . . . . . . . . DC to 100kHz • External Clock (Applied to Pin 3) can be Used Instead of 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 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 until 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, VDD should be greater than 5V. • Operates With Very Slow Clock Rise and Fall Times • Capable of Driving Six Low Power TTL Loads, Three Low-Power Schottky Loads, or Six HTL Loads Over the Rated Temperature Range • Symmetrical Output Characteristics • 100% Tested for Quiescent Current at 20V The RC oscillator, shown in Figure 2, oscillates with a frequency determined by the RC network and is calculated using: • 5V, 10V, and 15V Parametric Ratings • Meets All Requirements of JEDEC Standard No. 13B, “Standard Specifications for Description of ‘B’ Series CMOS Devices” 1 f = ----------------------------------2.3 R TC C TC Description 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.

Addendum-Page 1 PACKAGE OPTION ADDENDUM www.ti.com 15-Oct-2009 (2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability information and additional product content details. TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
