What are the key features of CD4517BE?
- Dual 64-stage static shift register providing 128 total bits of serial delay in a single 16-pin DIP package
- Wide supply voltage range of 3 V to 18 V enabling compatibility with both low-voltage CMOS and legacy TTL-level systems
- Static shift register architecture retains data at zero clock frequency, suitable for low-power hold modes in battery applications
What is CD4517BE used for?
The CD4517BE is used in serial data delay lines, digital audio echo circuits, and pattern generators where a programmable number of clock cycles of serial data delay is needed. Its dual 64-stage structure allows cascading to 128 stages or parallel use as two independent delay channels in data communication test equipment and embedded signal processing boards.

Frequently Asked Questions
How many bits of serial delay does the CD4517BE provide per channel?
Each of the two channels in the CD4517BE provides 64 stages of serial shift register delay, totaling 128 bits across both channels. Data entered at the serial input appears at the output after exactly 64 clock cycles per channel. The two channels can be cascaded to achieve 128-stage delay or used independently for dual-channel 64-bit serial buffering.
What supply voltage range does the CD4517BE support and how does it compare to HC-family logic?
The CD4517BE operates across a supply voltage range of 3 V to 18 V, which is broader than the HC-family range of 2 V to 6 V. This wide range makes the CD4517BE backward compatible with 12 V and 15 V legacy CMOS systems where HC-family devices would be out of specification. However, HC devices offer higher switching speeds at 5 V.
In which audio or communication application does the static shift register feature of the CD4517BE provide a design advantage?
In digital audio echo or delay-line circuits, the CD4517BE's static register holds sampled audio data indefinitely when the clock is paused, allowing variable delay control without data loss. Clocking at 8 kHz through all 64 stages creates an 8 ms delay per channel, useful for simple reverb or echo effects in low-cost embedded audio processing boards operating at 5 V supply.
