Description and Introduction

10kV ESD-Protected / Quad 5V RS-485/RS-422 Transmitters The MAX3042BESE is a quad, low-voltage, CMOS analog multiplexer manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Configuration:** Quad 2:1 multiplexer (4 channels).
- **Supply Voltage Range:** +1.8V to +5.5V (single supply).
- **On-Resistance (RON):** 5Ω (typical) at V+ = 4.5V.
- **On-Resistance Flatness (ΔRON):** 1Ω (typical).
- **Charge Injection:** 10pC (typical).
- **Bandwidth:** 200MHz (-3dB).
- **Leakage Current (OFF):** ±1nA (max at +25°C).
- **Crosstalk Rejection:** -90dB (at 1MHz).
- **Operating Temperature Range:** -40°C to +85°C.
- **Package:** 16-pin narrow SOIC (MAX3042BESE).

### **Descriptions:**
- The MAX3042BESE is a high-performance, low-voltage analog multiplexer designed for precision signal routing in battery-powered and portable applications.
- It features low on-resistance and minimal charge injection, making it suitable for data acquisition, audio switching, and communication systems.
- The device operates from a single supply and is compatible with both TTL and CMOS logic levels.

### **Features:**
- **Low Voltage Operation:** Works down to 1.8V.
- **Low On-Resistance:** 5Ω (typ) ensures minimal signal distortion.
- **High Bandwidth:** 200MHz supports high-speed signal switching.
- **Low Charge Injection:** Reduces glitches during switching.
- **Fast Switching:** tON = 35ns, tOFF = 20ns (typical).
- **TTL/CMOS-Compatible Logic Inputs.**
- **ESD Protection:** ±15kV (Human Body Model).

The MAX3042BESE is ideal for applications requiring low distortion, high-speed signal switching, and low power consumption.
