It handles the high-voltage transmit pulse and then switches to route the low-level echo signal to the receive chain, all within a 65 MHz -3dB bandwidth. The part operates from a single supply as low as 1.62 V up to 5.5 V, or from dual supplies spanning ±2.7 V to ±5.5 V, giving the system designer flexibility to match either the analog front-end rails or the digital controller I/O voltage. Packaged in a 56-TQFN (11x5 mm) with an exposed pad for thermal management, it is rated for 0°C to 70°C ambient — typical for benchtop and cart-based ultrasound systems in controlled clinical environments. ## Package and mounting — 56-TQFN, surface-mount, tray delivery The 56-lead TQFN (11x5 mm) with exposed pad is a surface-mount package. The exposed pad must be soldered to a thermal land on the PCB — it is the primary heat path and also provides a low-inductance ground return for the switch core. ## Lifecycle and compliance — active, ROHS3, no obsolescence concern The MAX4937CTN+ carries an active lifecycle status. The part is ROHS3 compliant, so it meets the current EU restriction on hazardous substances without exemption. For a BOM line that needs a qualified ultrasound transmit/receive switch, this part has no last-time-buy risk and no compliance gap.","metaTitle":"MAX4937CTN+ Transmit/Receive Switch, 65 MHz, 56-TQFN","metaDescription":"MAX4937CTN+ 8-channel transmit/receive switch for ultrasound, 65 MHz bandwidth, single 1.62V–5.5V or dual ±2.7V–5.5V supply.
