Description and Introduction

Precision, 8-Channel/Dual 4-Channel, High-Performance, CMOS Analog Multiplexers The MAX309CPE is a quad RS-422/RS-485 receiver manufactured by Maxim Integrated. Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Type:** Quad RS-422/RS-485 Receiver  
- **Package:** 16-Pin PDIP (Plastic Dual In-Line Package)  
- **Operating Voltage:** +5V  
- **Number of Receivers:** 4  
- **Data Rate:** Up to 10Mbps  
- **Input Sensitivity:** ±200mV  
- **Input Hysteresis:** 50mV (typical)  
- **Propagation Delay:** 20ns (typical)  
- **Common-Mode Input Range:** ±12V  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Operating Temperature Range:** 0°C to +70°C  

### **Descriptions:**  
The MAX309CPE is a high-speed, quad differential line receiver designed for RS-422 and RS-485 communication applications. It features fail-safe circuitry, ensuring a logic-high output when inputs are open, shorted, or terminated but not driven. The device is optimized for noise immunity and high-speed data transmission.  

### **Features:**  
- **Fail-Safe Design:** Guarantees a logic-high output with open, shorted, or unterminated inputs.  
- **High-Speed Operation:** Supports data rates up to 10Mbps.  
- **Wide Common-Mode Range:** ±12V allows robust performance in noisy environments.  
- **Low Power Consumption:** Typically draws 20mA supply current.  
- **ESD Protection:** ±15kV protection on receiver inputs.  
- **Industrial Temperature Range:** Available in commercial (0°C to +70°C) and industrial (-40°C to +85°C) versions.

Alternative Part Number

  • DG509ACJ+ --: Dual 4-channel analog multiplexer in a 16-pin DIP with similar on-resistance and supply range, a common drop-in functional replacement for the MAX309.
  • ADG509AKNZ --: Pin-compatible dual 4-channel CMOS multiplexer in 16-pin DIP with comparable Ron and switching characteristics, widely used as a MAX309 substitute.
  • CD4052BE --: Low-cost dual 4-channel analog multiplexer/demultiplexer in 16-pin DIP; lower precision but functionally similar and readily available as a general replacement.
  • DG509ACPE --: Dual 4-channel analog multiplexer in the same 16-pin DIP package with similar on-resistance and supply requirements, a common drop-in replacement for the MAX309.
  • ADG509FKN --: Dual 4-channel CMOS multiplexer with comparable RON and switching characteristics, widely used as a functional substitute for the MAX309 in DIP-16 designs.
  • DG509ACJ --: Dual 4-channel analog multiplexer in a 16-pin DIP, functionally equivalent to the MAX309 with similar on-resistance and switching characteristics.
  • ADG509AKN --: Pin-compatible dual 4-channel CMOS multiplexer in 16-pin DIP, widely used as a direct replacement for the MAX309 in analog signal routing.
