ON Semiconductor 74F190PC: 4-Bit Binary Up/Down Counter

The 74F190PC is a versatile integrated circuit designed and manufactured by ON Semiconductor, a leader in energy-efficient innovations. This 4-bit binary up/down counter is a fundamental component for a variety of digital applications where counting operations are essential. The 74F190PC is a part of the high-speed 74F series, known for its fast switching capabilities and robust performance.

Constructed with advanced silicon-gate technology, the 74F190PC offers users a synchronous reversible counter with a clear function. It is capable of counting in both up and down modes, which makes it exceptionally useful for precision counting applications. The counter advances on either the rising edge of the clock while counting up or the falling edge while counting down, providing flexibility in control and synchronization.

The device features a 4-bit binary counter that can be fully synchronous in both count modes, ensuring accurate and reliable operation. The built-in lookahead carry capability allows for high-speed counting without significant delays, which is critical for operations requiring quick response times.

Key specifications of the 74F190PC include:

• Logic Type: Up/Down Counter
• Counting Sequence: Up/Down
• Number of Circuits: 1
• Number of Bits per Element: 4
• Output Current: 50 mA
• Supply Voltage Range: 4.5V to 5.5V
• Operating Temperature Range: 0°C to +70°C
• Package / Case: 16-DIP (0.300", 7.62mm)

The 74F190PC also includes features such as a Master Reset input and a Carry Output for cascading multiple counters. This makes it possible to create extended bit count lengths beyond the 4-bit limit by linking several counters in series. The Master Reset input allows for quick initialization or synchronization of the counter, which is crucial for maintaining count integrity.

ON Semiconductor's 74F190PC is offered in a DIP (Dual In-line Package), making it suitable for breadboard prototyping and easy insertion into standard PCBs. This device is commonly used in digital clocks, frequency counters, digital panels, and various other systems requiring precise counting mechanisms.

Whether for educational projects, industrial applications, or commercial products, the 74F190PC from ON Semiconductor provides a reliable and efficient solution for your counting needs.
