CD74HC193M

CD74HC193M Description

The CD74HC193M from Texas Instruments is a high-speed 4-bit synchronous up/down binary counter designed for precision counting applications. Operating within a 2V to 6V supply range, it supports a count rate of 29 MHz, making it suitable for high-performance digital systems. This ROHS3-compliant device features asynchronous reset and positive-edge triggering, ensuring reliable operation in synchronous logic designs. Packaged in a 16-SOIC tube, it is optimized for surface-mount (SMD) applications and carries a Moisture Sensitivity Level (MSL) 1 rating, indicating unlimited floor life under typical storage conditions.

CD74HC193M Features

• 4-bit bidirectional counter with up/down counting capability, offering flexible control for increment/decrement operations.
• Synchronous timing ensures precise clock-driven counting, while asynchronous reset allows immediate clearing of the counter state.
• Wide voltage range (2V–6V) and 29 MHz count rate enable compatibility with mixed-voltage systems and high-speed applications.
• Positive-edge triggering enhances noise immunity and timing accuracy.
• Surface-mount 16-SOIC package saves board space and simplifies automated assembly.
• REACH unaffected and ROHS3 compliant, meeting stringent environmental regulations.

CD74HC193M Applications

• Frequency dividers and pulse generators in communication systems.
• Industrial automation for position counting in encoders or motor control.
• Digital instrumentation such as event counters or timer circuits.
• Embedded systems requiring precise clock division or sequence generation.
• Consumer electronics (e.g., smart appliances) where reliable counting logic is critical.

Conclusion of CD74HC193M

The CD74HC193M stands out for its high-speed operation, bidirectional counting, and robust design, making it ideal for applications demanding accuracy and flexibility.
