Key Features
- 4-bit synchronous decade (BCD) up/down counter with separate UP and DOWN clock inputs for flexible bidirectional counting in digital logic designs
- Asynchronous parallel load and preset inputs allow immediate initialization to any BCD count value without waiting for a clock edge
- Cascadable carry-out (TCO UP) and borrow-out (TCO DOWN) outputs enable multi-decade counter chains with minimal external logic
Applications
The CD40192BF is used in digital frequency counters, event counters, and timer circuits that need bidirectional BCD counting with display interface compatibility. Its separate up/down clocks and carry/borrow outputs make it straightforward to cascade multiple devices for multi-digit decimal counting in industrial control panels and instrumentation. The ceramic DIP package also makes it a popular choice for legacy industrial equipment repair and military/high-reliability replacement applications.

Frequently Asked Questions
What counting mode and bit width does the CD40192BF support, and what package does it use?
The CD40192BF is a 4-bit synchronous decade (BCD) up/down counter that supports bidirectional counting with separate UP and DOWN clock inputs. It is housed in a 16-pin ceramic dual-in-line package (CDIP), making it suitable for high-reliability industrial, military, and legacy digital logic applications.
How are multiple CD40192BF devices cascaded to build multi-decade counters?
Cascading CD40192BF devices is done by connecting the TCO UP (carry-out) output of one stage to the UP clock of the next and the TCO DOWN (borrow-out) to the DOWN clock of the next stage. This allows multi-decade BCD counting chains to be built without additional logic, suitable for 2-digit, 3-digit, or longer decimal counter displays in frequency meters and industrial timers.
What load capacitance rating applies to the CD40192BF, and how does it affect clock frequency limits?
The CD40192BF is specified with a 50 pF load capacitance. This rating defines the worst-case capacitive load on its outputs and influences the maximum clock frequency achievable; at 50 pF, the 4000-series CMOS family typically operates reliably up to several MHz depending on supply voltage, making it compatible with low-to-medium-speed digital counting applications.
