Frequently Asked Questions
What is the supply voltage range for the CD40103BNSR?
The CD40103BNSR operates over a wide supply voltage range of 3V to 18V, making it compatible with both TTL (5V) and CMOS logic systems. This flexibility allows it to be used in a broad range of applications from battery-powered devices to industrial control systems.
Can the CD40103BNSR be cascaded to create multi-stage counters?
Yes, the CD40103BNSR features a synchronous carry output that allows multiple devices to be cascaded together easily. By connecting the carry output of one CD40103BNSR to the enable input of the next, you can create multi-stage down counters with larger counting ranges beyond the base 8-stage (256-count) capacity.
What package type is the CD40103BNSR and what are its key mechanical specs?
The CD40103BNSR comes in a 16-Pin SOP (Small Outline Package), also identified by JESD-30 code R-PDSO-G16. It is a surface-mount device rated for a load capacitance of 50 pF and is RoHS-compliant with Pb-free construction (JESD-609 code e4), suitable for automated PCB assembly.
What is the maximum operating frequency of the CD40103BNSR?
The CD40103BNSR has a maximum operating frequency of 700 kHz at nominal supply voltage with a 50 pF load capacitance. This makes it suitable for moderate-speed counting and timing applications in digital logic circuits and instrumentation systems.
What are common applications for the CD40103BNSR?
The CD40103BNSR is commonly used in digital countdown timers, frequency dividers, programmable time-delay circuits, industrial automation controllers, and event counters. Its presettable load input and synchronous down-counting make it particularly useful in sequencing circuits, real-time clocks, and multi-stage counting systems.
