Product Introduction

Overview

The TMUX1219DCKR is a general-purpose complementary metal-oxide semiconductor (CMOS) single-pole double-throw (SPDT) switch produced by Texas Instruments. This device is designed to switch between two source inputs based on the state of the SEL pin. It operates over a wide supply range of 1.08 V to 5.5 V, making it versatile for various applications from personal electronics to building automation. The TMUX1219 supports bidirectional analog and digital signals on the source (Sx) and drain (D) pins, ranging from GND to VDD. Its low supply current of 4 nA and fail-safe logic features make it suitable for portable and complex system designs.

Key Specifications

Parameter Description Value
Package SOT-SC70 (DCK) 6 pins
Operating Temperature Range °C -40 to 125
Supply Voltage Range V 1.08 to 5.5

Key Features

  • Rail to Rail Operation: The valid signal path input/output voltage ranges from GND to VDD.
  • Bidirectional Signal Path: Conducts equally well from source (Sx) to drain (D) or from drain (D) to source (Sx).
  • 1.8 V Logic Compatible Inputs: Ensures compatibility with both TTL and CMOS logic when operating within the valid supply voltage range.
  • Fail-Safe Logic: Allows voltages on the control pins to be applied before the supply pin, protecting the device from potential damage.
  • Low On-Resistance: 3 Ω, which minimizes signal loss and distortion.
  • Low Supply Current: 4 nA, making it suitable for portable applications.
  • Break-Before-Make Switching: Ensures that the output first breaks from the on-state switch before making the connection with the next on-state switch.
  • ESD Protection: Up to 2000 V (HBM)).

Applications

  • Analog and Digital Switching: Suitable for switching both analog and digital signals.
  • I2C and SPI Bus Multiplexing: Can be used to multiplex I2C and SPI bus signals).
