Applications
The CD4516BF is used in digital frequency division, event counting, and programmable timer circuits requiring bidirectional 4-bit counting with synchronous preset capability. Its cascade carry-out (TCO) output enables multiple devices to be chained for wider counters, supporting 8-bit, 12-bit, or 16-bit counting applications in industrial control and test equipment. The ceramic DIP package makes it suitable for military, aerospace, and high-reliability industrial designs that demand long service life under environmental stress.

Frequently Asked Questions
How wide is the CD4516BF counter and can multiple devices be cascaded for wider counting?
The CD4516BF is a 4-bit binary counter that can count from 0 to 15. Multiple units can be cascaded using the TCO (terminal carry out) output connected to the clock enable of the next stage, enabling 8-bit, 12-bit, or 16-bit synchronous counters without additional logic, covering count ranges up to 65535 with 4 cascaded devices.
What is the preset load function of CD4516BF and how is it used in programmable timer circuits?
The CD4516BF includes a synchronous parallel load input that captures all 4 data inputs simultaneously on the clock edge when asserted. This allows designers to preset the counter to any value from 0 to 15, enabling modulo-N count sequences for programmable frequency dividers and timers where the count period needs to be adjusted without redesigning the circuit.
Why would CD4516BF be selected over a plastic DIP equivalent in an aerospace design?
The CD4516BF is housed in a 16-pin ceramic DIP package (R-GDIP-T16), which provides superior moisture resistance and hermetic sealing compared to plastic PDIP equivalents. Aerospace and military designs require ceramic packaging to meet MIL-STD qualification criteria for extended temperature cycling and humidity exposure, ensuring counter operation over the full military temperature range of -55°C to 125°C.
How does the bidirectional counting capability of CD4516BF benefit motor position tracking applications?
In a motor position tracking circuit, the CD4516BF can increment its 4-bit count when the motor moves forward and decrement when it reverses, using the up/down control pin. This bidirectional counting across a 0 to 15 range allows tracking of rotational position or step count in a compact 4-bit register, with the TCO output signaling overflow for cascading to wider position registers.
