Overview
The TMUX9616PTR is a Texas Instruments analog switch IC featuring 16 independent single-pole, single-throw (SPST) channels. It supports dual supply voltages from ±20V to ±110V with an absolute maximum rating of 240V peak-to-peak. The device integrates cascadable 16-bit shift registers for SPI control, operating at clock frequencies up to 72MHz. Key electrical parameters include a low on-resistance (RONL) of 12Ω, turn-on time of 3μs maximum, and off-isolation of -70dB at 5MHz. It operates within an extended temperature range of –40°C to 125°C and is housed in a 48-pin LQFP package.
Feature Summary
- Integrated latch-up immunity by device construction
- Low off capacitance of 5pF and low on resistance of 12Ω
- Cascadable 16-bit shift register with latches for daisy-chain control
- Integrated bleed resistors on source and drain pins for capacitive load discharge
Applications
- Medical ultrasound imaging
- Non-destructive testing (NDT) metal flaw detection
- Piezoelectric transducer drivers
- Ultrasonic flow transmitters
- Optical MEMS modules
Procurement Notes
Verify the ordering suffix PTR corresponds to the PT package (LQFP, 48 pins) with integrated bleed resistors. Confirm that the specific revision level matches the design requirements, as documentation indicates revisions such as SCDS436A revised December 2024. Ensure compatibility with the required logic voltage levels (1.8V to 5V) and high-voltage supply configurations during procurement validation.
Selection Notes
Select the TMUX9616PTR over the TMUX9616N variant when integrated output bleed resistors are required for discharging capacitive loads like piezoelectric sensors. Verify that the 48-pin LQFP package dimensions fit the PCB layout constraints. Ensure the application utilizes dual supplies within the ±20V to ±110V range to leverage the device's full high-voltage capabilities and latch-up immunity features.
Part Context
The TMUX9616x series consists of 16-channel high-voltage analog switches designed for precision signal routing. The TMUX9616PTR specifically denotes the version with integrated bleed resistors, distinguishing it from the TMUX9616N which lacks this feature. Both variants share identical pinouts and electrical characteristics except for the presence of the internal discharge resistors, allowing for flexible design choices based on load requirements.
Replacement Considerations
The TMUX9616N serves as a direct pin-compatible alternative if integrated bleed resistors are not needed. No other public substitute part numbers are confirmed in the provided documentation.
