This integrated circuit is designed to be a versatile component in digital systems, with a wide range of applications from calculators to computer systems, where a reliable and precise counting mechanism is required.

Key Features:

• Presettable 4-Bit Binary Up/Down Counter: The CD40192BNSR is capable of counting in both up and down modes, making it highly adaptable for various counting operations.
• Synchronous Operations: All operations, including setting the outputs to the preset number, counting up or down, and zeroing the counter, are synchronized with the clock input to ensure accurate and reliable counting.
• Wide Operating Voltage Range: The device supports a voltage range from 3V to 18V, accommodating various logic level requirements and making it suitable for interfacing with other logic families.
• Medium Speed Operation: It operates at a speed of 16 MHz (typical) at VDD - VSS = 10V, allowing for medium-speed counting applications.
• Fully Static Operation: The counter is fully static, which means it does not require a minimum clock frequency and can maintain the present state indefinitely without clock input.
• Standardized, Symmetrical Output Characteristics: The outputs have standardized characteristics that are symmetrical, which is essential for high noise immunity and stable output signals.
• 100% Tested for Quiescent Current at 20V: The device is thoroughly tested to ensure minimal quiescent current, even at the maximum rated voltage, which contributes to low power consumption.
• 5V, 10V, and 15V Parametric Ratings: The CD40192BNSR has been tested and rated at 5V, 10V, and 15V, providing flexibility in different power environments.
• Maximum Input Current of 1 µA at 18V: It has an extremely low input current requirement, minimizing the impact on the circuits to which it is connected.
• Meets All Requirements of JEDEC Tentative Standard No. 13B: As per the JEDEC standard, the CD40192BNSR conforms to the stringent requirements for solid-state devices.
