The TX810IRHHT is a 8-channel programmable Transmit/Receive Switch provides an integrated solution for a wide range of ultrasound applications. The internal diodes limit the output voltage when high voltage transmitter signals are applied to the input. While the insertion loss of TX810 is minimized during receive mode. Unlike conventional T/R switches, the TX810 contains a 3-bit interface used to program bias current from 7 to 0mA for different performance and power requirements. When the it bias current is set as 0mA (i.e., high-impedance mode), the device is configured as power-down mode. In the high-impedance mode, TX810 does not add additional load to high-voltage transmitters. In addition, the device can wake up from power-down mode in less than 1µs. With these advanced programmability features, significant power saving can be achieved in systems.
● Flexible programmability
● Easy power-up/down control
● Fast wake up time
● Dual supply operation
● Optimized insertion loss
●Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
