Key Features
- Bidirectional 4-bit binary counter with up/down counting capability and preset inputs for programmable initial count values in timing and sequencing circuits
- Carry-out (TCO) output enabling direct cascade of multiple CD4516 stages to build 8-bit, 12-bit, or wider synchronous counter chains
- Ceramic 16-pin DIP package from the 4000 CMOS family offering reliable operation across the full -55°C to +125°C military temperature range
Applications
The CD4516BF3A is used in digital timing circuits, frequency dividers, and programmable event counters in industrial and military electronics where a presettable bidirectional 4-bit counter is required. Its up/down counting and carry-out output allow multiple devices to be cascaded for extended counter widths without additional logic, suiting applications in rotary encoder interfaces, position tracking, and BCD-to-binary conversion chains. The ceramic DIP package makes it a preferred choice for high-reliability designs in aerospace, defence, and automotive systems.

Frequently Asked Questions
Can the CD4516BF3A count in both directions, and how is the count direction selected?
Yes, the CD4516BF3A is a bidirectional 4-bit binary counter that counts up or down based on the logic level on its UP/DOWN control input. A HIGH on the UP/DOWN pin selects up-counting through the 16-state binary sequence, while a LOW selects down-counting. This allows the same device to serve as both an incrementing and a decrementing counter in position-tracking or timing circuits.
How does the carry-out output of CD4516BF3A enable cascading for wider counter designs?
The CD4516BF3A provides a TCO (terminal count output) carry-out pin that goes active when the counter reaches its terminal count—15 on up-count or 0 on down-count. Connecting this TCO to the clock-enable or clock input of an adjacent CD4516BF3A stage extends the counter width to 8 bits or beyond, allowing multi-stage ripple or synchronous counters with 50 pF load capacitance per output.
What operating temperature range does the ceramic CD4516BF3A package support in high-reliability applications?
The CD4516BF3A is housed in a 16-pin ceramic DIP (R-GDIP-T16) package, which supports an extended operating temperature range of -55°C to +125°C, meeting MIL-grade requirements. This makes it suitable for aerospace avionics, military ground equipment, and oil-field instrumentation where plastic packages would fail under thermal cycling or moisture exposure.
Does CD4516BF3A support preset loading, and in which control applications is that feature critical?
The CD4516BF3A includes preset (LOAD) inputs that let the designer jam a 4-bit binary word into the counter on demand, bypassing the sequential count. This is critical in programmable-delay timers, frequency-synthesis dividers, and PWM period-control circuits where the counter must restart from a non-zero initial value—such as resetting to decimal 10 in a divide-by-6 prescaler built from a 4-bit binary counter.
