Description and Introduction

Ultra Low-Power, Single/Dual-Supply Comparators The MAX921CUA is a high-speed, low-power differential line driver manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information:  

### **Manufacturer:**  
- **MAX** (Maxim Integrated, now part of Analog Devices)  

### **Specifications:**  
- **Type:** Differential Line Driver  
- **Supply Voltage:** **4.5V to 5.5V**  
- **Operating Temperature Range:** **-40°C to +85°C**  
- **Data Rate:** **Up to 400Mbps**  
- **Propagation Delay:** **1.7ns (typical)**  
- **Output Voltage Swing:** **±350mV (differential, typical)**  
- **Power Consumption:** **Low power (typically 50mW at 5V supply)**  
- **Package:** **8-pin µMAX (MSOP)**  

### **Descriptions:**  
- The MAX921CUA is designed for high-speed data transmission over twisted-pair or controlled-impedance PCB traces.  
- It provides **LVDS-compatible** differential outputs for noise immunity in high-speed applications.  
- Suitable for **video transmission, automotive infotainment, and communication systems**.  

### **Features:**  
- **High-speed differential signaling** (up to 400Mbps).  
- **Low power consumption** for energy-efficient designs.  
- **Wide supply voltage range** (4.5V to 5.5V).  
- **Small form factor** (8-pin µMAX package).  
- **Low propagation delay** for real-time signal integrity.  
- **Compatible with LVDS receivers** for seamless integration.

Application Scenarios & Design Considerations

Ultra Low-Power, Single/Dual-Supply Comparators

Alternative Part Number

  • LT1715CMS8 --: Single-supply comparator with similar response time and push-pull output, suitable drop-in for many MAX921 applications.
  • TLV3201AIDBVR --: Low-power rail-to-rail comparator in small package, good functional substitute when supply and speed requirements are moderate.
  • LM393DR --: Widely available dual open-collector comparator; usable alternative if output stage and dual-channel configuration are acceptable.
  • LTC1440CS8 --: Single/dual supply micropower comparator with internal reference, functionally similar to MAX921 and pin-compatible in many designs.
  • TLV3011ACDBVR --: Low-power comparator with integrated voltage reference, suitable drop-in replacement for battery-powered comparator applications.
  • LMV331IDBVR --: General-purpose low-voltage comparator offering similar supply range and open-drain output behavior for cost-sensitive designs.
  • LT1716CS5 --: Single comparator in SOT-23-5 with similar low-voltage operation and push-pull output, a common drop-in style alternative to the MAX921 comparator family.
  • LMV7219M5 --: Fast low-power comparator in SOT-23-5 with push-pull output, widely used as a functional substitute for MAX921-type comparators.
