Description and Introduction

4.5? Quad SPST Analog Switches in UCSP The MAX4738EUD is a low-voltage, single-supply, single-pole double-throw (SPDT) analog switch manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage Range:** +1.8V to +5.5V  
- **Low On-Resistance (RON):** 0.5Ω (typical at +5V supply)  
- **RON Flatness:** 0.1Ω (typical)  
- **Charge Injection:** 10pC (typical)  
- **Off-Isolation:** -80dB (at 1MHz)  
- **Crosstalk Rejection:** -80dB (at 1MHz)  
- **Bandwidth (-3dB):** 200MHz  
- **Switching Time (tON/tOFF):** 20ns/15ns (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 14-pin TSSOP (MAX4738EUD)  

### **Description:**
The MAX4738EUD is a high-performance, low-voltage SPDT analog switch designed for precision signal routing in portable and low-power applications. It offers low on-resistance, minimal distortion, and fast switching, making it suitable for audio, video, and data signal switching.

### **Features:**
- **Wide Supply Range:** Operates from +1.8V to +5.5V  
- **Low On-Resistance:** 0.5Ω (maximizes signal integrity)  
- **Low Power Consumption:** <1µA (typical supply current)  
- **Fast Switching:** 20ns turn-on, 15ns turn-off  
- **High Off-Isolation & Crosstalk Rejection:** -80dB  
- **TTL/CMOS-Logic Compatible Control Inputs**  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Pb-Free & RoHS Compliant**  

This switch is ideal for battery-powered devices, audio/video routing, and communication systems requiring high-speed, low-distortion signal switching.
