Frequently Asked Questions
What counting mode does the CD4520BME4 support?
The CD4520BME4 supports 4-bit binary up-counting only, counting from 0 to 15 before rolling over. It contains two independent 4-bit binary counters that can be cascaded by connecting the carry output of the first counter to the clock input of the second, extending the count range to 8 bits or beyond.
Does the CD4520BME4 have Schmitt trigger clock inputs?
Yes, the CD4520BME4 features Schmitt trigger inputs on its clock pins, providing hysteresis that rejects slow-rising or noisy clock edges. This makes the device reliable in environments with electrical noise, long PCB traces, or slow clock transitions that might cause false triggering in standard non-Schmitt counter inputs.
What package does the CD4520BME4 use and is it RoHS compliant?
The CD4520BME4 is housed in a 16-pin SOIC package, designated JESD-30 code R-PDSO-G16. It is RoHS compliant with Pbfree Code: Yes and JESD-609 Code: e4, confirming lead-free construction suitable for modern environmentally regulated manufacturing environments worldwide.
What logic family does the CD4520BME4 belong to and what are the supply voltage requirements?
The CD4520BME4 belongs to the 4000/14000/40000 CMOS logic family, which typically operates over a wide supply voltage range of 3 V to 18 V. This wide range allows the device to interface with both low-voltage CMOS logic and legacy TTL-level systems, making it highly versatile for mixed-voltage digital designs.
