Frequently Asked Questions - CD40103BPW TEXAS INSTRUMENTS
What is the CD40103BPW?
The CD40103BPW is a CMOS programmable divide-by-N counter from Texas Instruments. It is used in frequency division, timing, and counting applications.
What is the operating voltage range?
The device operates from 3 V to 18 V DC, making it compatible with standard CMOS and TTL logic levels.
How do I set the divide factor N?
The divide factor N is set via the preset inputs (P0-P7). The counter divides the input clock frequency by N, where N is the binary value loaded into the preset inputs.
What is the maximum clock frequency?
Typical maximum clock frequency is 12 MHz at VDD = 10 V, but it varies with supply voltage and temperature. Lower voltage reduces maximum frequency.
What package does the CD40103BPW come in?
It is available in a TSSOP-16 (Thin Shrink Small Outline Package) with 16 pins, suitable for surface mount assembly.
How do I reset the counter?
The counter can be reset synchronously via the RESET pin (active high). When RESET is high, the counter output is set to low (all Q outputs low).
Can I cascade multiple CD40103BPW devices?
Yes, they can be cascaded to achieve larger division ratios. Connect the CARRY OUT (CO) of the first stage to the clock input of the next stage.
What is the output drive capability?
The outputs can source or sink up to 10 mA typically, sufficient to drive standard CMOS inputs or LEDs with series resistors.
Is the device static-sensitive?
Yes, it is sensitive to electrostatic discharge (ESD class 1). Use proper ESD safety measures during handling and assembly.
Where can I find the full datasheet?
The full datasheet is available on the Texas Instruments website (product page for CD40103BPW) and includes detailed electrical characteristics and timing diagrams.
