2-channel 2:1 analog multiplexer with 18-V overvoltage protection

 

Description

The TMUX1072 is a high-speed, 2-channel, 2:1, analog switch with integrated overvoltage detection and powered off protection. The device is bidirectional and can be used as a 2:1 or 1:2 switch while supporting signals beyond VCC up to 5.5 V.

The protection on the I/O pins of the TMUX1072 tolerates a maximum of 18 V with automatic shutoff circuitry to prevent damage to system components behind the switch. This protection is used for power sequencing. Some boards in the system may be powered up before others are ready to receive signals. The device detects overvoltage and overtemperature events, and provides an open drain output signal through the FLT pin.

Features

  • Supply range 2.3 V to 5.5 V
  • Powered off protection: I/O pins Hi-Z when
    VCC = 0 V
  • 6-V Overvoltage and overtemperature detection with fault indicator pin
  • 18-V Overvoltage protection (OVP) on common pins
  • Support signals beyond VCC up to 5.5 V
  • Low RON of 6 Ω
  • BW of 1.2 GHz typical
  • CON of 4.5 pF typical
  • Low power disable mode
  • 1.8-V Compatible logic inputs
  • ESD protection exceeds JESD22
    • 2000-V Human body model (HBM)
  • Small 2.00 mm x 1.70 mm QFN package available
