Microchip MCP6564T-E/ST: A Quad-Channel High-Speed Push-Pull Output Comparator

In the realm of analog signal processing, the ability to quickly and accurately compare voltage signals is fundamental. The Microchip MCP6564T-E/ST stands out as a premier solution, integrating four independent high-speed comparators into a single, space-saving package. This device is engineered for applications demanding rapid response times, low power consumption, and robust output drive capability.

A defining feature of the MCP6564T-E/ST is its high-speed performance, with a typical propagation delay of just 45 ns. This swift response is critical for time-sensitive systems such as over-current protection circuits, high-frequency pulse-width modulation (PWM) generation, and fast threshold detection in data acquisition systems. Each of the four comparators operates with low supply current, making the device suitable for power-conscious designs without sacrificing speed.

The push-pull output stage is another significant advantage. Unlike comparators with open-drain outputs that require an external pull-up resistor, the push-pull architecture provides a strong, rail-to-rail output swing. This ensures fast rising and falling edges, minimizes signal integrity issues, and simplifies circuit design by eliminating external components. The output is capable of sourcing and sinking current directly, which is ideal for driving capacitive loads or digital logic inputs like those of MCUs and FPGAs.

Designed for versatility, the device supports a wide supply voltage range from 2.0 V to 5.5 V, accommodating both 3.3 V and 5 V systems. Its input common-mode range extends beyond the supply rails (VSS - 0.3 V to VDD + 0.3 V), providing design flexibility in interpreting signals close to the power rails. Furthermore, the MCP6564T-E/ST is characterized for operation over an extended temperature range (-40°C to +125°C), ensuring reliability in industrial and automotive environments.

Housed in a compact TSSOP-14 package, this comparator is perfect for high-density PCB layouts. Applications span from motor control and automotive systems to portable instrumentation and communication infrastructure, wherever multiple channels of precise, high-speed voltage comparison are needed.
