TX810IRHHT

Overview

The TX810IRHHT is an eight-channel transmit/receive switch integrated circuit manufactured by Texas Instruments, designed for ultrasound applications. It operates on a single 5 V supply with a minimum voltage of 2.5 V and draws a maximum power supply current of 50 uA. The device features a bandwidth of 140 MHz, a maximum run time of 600 ps, and a maximum isolation time of 2.4 us. It dissipates up to 644 mW of power and functions within a temperature range of 0 C to +70 C. Packaged in a VQFN-36 surface-mount format, it supports reel, cut tape, and MouseReel packaging options.

Feature Summary

Configurable as an eight-channel programmable transmit/receive switch for ultrasound systems
Low noise performance with high bandwidth capability
Fast switching speeds with minimal run and isolation times

Applications

Ultrasound imaging systems
Medical diagnostic equipment
Transmit/receive front-end modules

Procurement Notes

Verify the exact part number TX810IRHHT against official Texas Instruments documentation to ensure correct suffix identification. Confirm package type is VQFN-36 and operating temperature range matches application requirements. Check humidity sensitivity handling instructions during storage and assembly. Ensure compatibility with the TX810EVM evaluation module if development support is needed.

Selection Notes

Select this component when designing ultrasound transducer interfaces requiring eight independent channels. Verify that the 5 V single-supply operation aligns with system power constraints. Consider the VQFN-36 footprint for PCB layout planning. Evaluate thermal dissipation capabilities given the 644 mW power rating under worst-case conditions.

Part Context

The TX810 belongs to the TX810 series of transmit/receive switches from Texas Instruments. It is distinct from other TI products like the SN65HVD1781 or MSP430 microcontrollers found in general catalogs. The EVM kit TX810EVM provides hardware support for evaluating this specific switch IC's performance in ultrasound applications.
