TMUX8213PWR

Overview

The TMUX8213PWR is a high-voltage analog switch featuring four independently controllable 1:1 single-pole single-throw (SPST) channels in a 16-pin TSSOP package. It supports dual supply voltages from ±10 V to ±50 V and single supply voltages up to 100 V, with an asymmetric dual supply range of 10 V to 50 V. The device maintains a maximum on-resistance of 10 Ω across the operating temperature range of -40°C to +125°C. Key electrical parameters include a typical off-isolation of -110 dB, a bandwidth of 420 MHz, and a propagation delay of 190 ps. Logic inputs support 1.8-V levels and tolerate up to 48 V.

Feature Summary

• Supports bidirectional signal paths for both analog and digital signals across source and drain pins.
• Features fail-safe logic circuitry allowing control pin voltages up to 48 V independent of power supply rails.
• Provides latch-up immunity to prevent parasitic high-current events in harsh environments.
• Maintains consistent on-resistance flatness and parametric performance across the entire supply voltage range.

Applications

• High voltage bidirectional switching
• Semiconductor test equipment
• Data acquisition systems (DAQ)
• Programmable logic controllers (PLC)

Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-16 package configuration required for your design. Confirm that the logic input type matches the TMUX8213 specification, which enables switches with either logic low or logic high states. Ensure the application environment remains within the specified ambient temperature limits of -40°C to +125°C for reliable operation.

Selection Notes

Select the TMUX8213PWR when the design requires four SPST switches capable of handling up to 100 V single supply or ±50 V dual supply. This part is suitable for applications needing fail-safe logic compatibility with 1.8-V, 3.3-V, or 5-V control signals. Consider the thermal dissipation characteristics of the TSSOP package if multiple channels are active simultaneously at high currents.

Part Context

The TMUX8213PWR belongs to the Texas Instruments TMUX821x family of high-voltage analog switches. This family includes the TMUX8211 and TMUX8212, which differ primarily in their logic activation requirements. The TMUX8213 specifically allows switching via either logic low or logic high inputs, offering greater flexibility in system control architectures compared to the other variants in the series.
