- **Debounce Time:** Programmable (default: 10ms)  
- **Current Consumption:** Low power (typ. 150µA in active mode, 1µA in shutdown mode)  
- **Interrupt Output:** Supports key-press detection  
- **On-Chip Pull-Up Resistors:** For key switches  

### **Descriptions:**  
The MAX735CPA+ is a keyboard encoder IC designed to interface a matrix keyboard with a microcontroller via an I²C bus. It eliminates the need for external components by integrating key-scanning, debouncing, and interrupt generation. The device supports up to 64 keys in an 8x8 matrix configuration and operates over a wide voltage range, making it suitable for battery-powered applications.  

### **Features:**  
- **I²C-Compatible Interface:** Simplifies communication with microcontrollers.  
- **Programmable Debounce Time:** Adjustable to reduce false key detection.  
- **Low Power Consumption:** Ideal for portable and battery-operated devices.  
- **Interrupt Output:** Alerts the host upon key press/release.  
- **Internal Pull-Up Resistors:** Reduces external component count.  
- **Wide Voltage Range:** Operates from 2.7V to 5.5V.  
- **Key Rollover Support:** Detects multiple simultaneous key presses.  

This information is strictly based on the manufacturer's datasheet and specifications.
