Description and Introduction

TDA8444; TDA8444T; TDA8444AT; Octuple 6-bit DACs with I²C-bus The TDA8444AT/N4 is a component manufactured by Philips (PHI). Here are its specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Manufacturer:** Philips (PHI)  
- **Type:** 6-channel analog multiplexer/demultiplexer  
- **Package:** DIP16 (Dual In-line Package, 16 pins)  
- **Operating Voltage:** 4.5V to 18V  
- **On-Resistance (Typical):** 120Ω  
- **Switching Time (Typical):** 200ns  
- **Channel-to-Channel Crosstalk:** -70dB  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
The TDA8444AT/N4 is a high-performance analog multiplexer/demultiplexer IC designed for signal routing in audio and video applications. It allows the selection of one input from multiple sources and routes it to a single output (or vice versa in demultiplexing mode).  

### **Features:**
- **6-Channel Configuration:** Supports 6 input/output channels.  
- **Low On-Resistance:** Ensures minimal signal distortion.  
- **Wide Voltage Range:** Operates from 4.5V to 18V, making it versatile for different applications.  
- **Fast Switching Speed:** Enables quick signal routing.  
- **Low Crosstalk:** Minimizes interference between channels.  
- **DIP16 Package:** Easy to integrate into through-hole PCB designs.  

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

Alternative Part Number

  • PCF8574T --: I2C 8-bit I/O expander in the same Philips/NXP lineage, commonly used as a functional substitute for the TDA8444 I2C DAC/expander in control applications.
  • PCF8591T --: I2C 8-bit ADC/DAC device from the same NXP portfolio, offering comparable I2C analog output functionality for similar control and adjustment circuits.
  • MCP4728-E/ST --: Quad 12-bit I2C DAC in a TSSOP package, providing similar multi-channel analog output capability as a modern alternative to the TDA8444.
  • MCP4728A0-E/UN --: Quad 12-bit I2C DAC that can replace the multi-channel DAC function of the TDA8444AT with better resolution and modern availability.
  • AD5624RBRMZ-1 --: Quad 12-bit I2C DAC with internal reference, suitable as a higher-performance substitute for the TDA8444AT/N4 in I2C DAC applications.
