What are the key features of CD4517BF3A?

  • Dual 64-bit serial shift register with intermediate outputs at 16th, 32nd, and 48th stages for flexible data tapping
  • Maximum clock frequency of 3 MHz suitable for low-to-medium speed digital delay and data buffering applications
  • Wide supply voltage range from 3 V to 15 V in the 4000-series CMOS family for versatile system integration
  • 16-pin ceramic CDIP package (JESD-30 R-GDIP-T16) for high-reliability and industrial-grade board designs

What is CD4517BF3A used for?

CD4517BF3A is used in digital delay lines, serial data buffering, and time-division multiplexing circuits where two independent 64-bit shift registers are needed in a single package. The intermediate tap outputs at the 16th, 32nd, and 48th stages make it suitable for programmable delay generation and pattern sequencing in industrial control systems. Its wide 3 V to 15 V supply range also makes it compatible with legacy CMOS and TTL-level systems in instrumentation and communication equipment.

Frequently Asked Questions

What clock frequency does CD4517BF3A support, and what data rates does that enable?

CD4517BF3A operates at a maximum clock frequency of 3 MHz, enabling serial data throughput of up to 3 Mbps per channel. With 2 independent 64-bit shift registers, this allows shifting 128 bits of data per clock cycle collectively, suitable for moderate-speed digital delay lines and data serialization tasks in industrial and instrumentation designs.

How do the intermediate tap outputs at stages 16, 32, and 48 add design flexibility to CD4517BF3A?

The intermediate tap outputs at the 16th, 32nd, and 48th shift register stages allow designers to extract delayed data versions without cascading multiple ICs. This means a single CD4517BF3A in its 16-pin ceramic DIP package can implement programmable delay increments of 16, 32, 48, or 64 bit-clock periods, reducing component count in timing and synchronization circuits.

Over what supply voltage range can CD4517BF3A operate, and how does this affect legacy system integration?

CD4517BF3A operates across a supply voltage range of 3 V to 15 V as part of the 4000/14000/40000 CMOS family, making it compatible with both modern 3.3 V microcontroller interfaces and legacy 5 V or 12 V CMOS logic systems. This broad range eliminates the need for level-shifting when integrating the shift register into mixed-voltage industrial and instrumentation designs.
