Description and Introduction

-5V/Adjustable, Negative-Output,Inverting, Current-mode PWM Regulators The MAX735EPA is a key matrix encoder manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX735EPA  
- **Type:** Key Matrix Encoder  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Operating Voltage:** 2.7V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Key Matrix Support:** 8x8 (64-key) matrix scanning  
- **Interface:** I²C-compatible serial interface  
- **Debounce Time:** Programmable (default: 10ms)  
- **Quiescent Current:** 150µA (typical)  
- **Interrupt Output:** Active-low open-drain interrupt output  

### **Descriptions:**
The MAX735EPA is a key matrix encoder designed to interface with a matrix of up to 64 keys using an 8x8 scanning configuration. It communicates via an I²C-compatible serial interface, reducing the number of microcontroller I/O pins required. The device includes built-in debounce circuitry and an interrupt output to signal key press/release events, improving system efficiency.  

### **Features:**
- **Low Power Consumption:** Operates at 150µA (typical) in active mode.  
- **Wide Voltage Range:** Supports 2.7V to 5.5V operation.  
- **Programmable Debounce:** Adjustable debounce time for key inputs.  
- **I²C Interface:** Simplifies communication with microcontrollers.  
- **Interrupt Output:** Reduces polling overhead by signaling key events.  
- **64-Key Support:** Scans an 8x8 key matrix.  
- **Industrial Temperature Range:** Operates from -40°C to +85°C.  

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