MD0101集成电路（IC）的专用规格书PDF中文资料

General Description

The Supertex MD0101 is a four channel, high voltage, current limiting protection device. It is designed to protect a low noise receiver from the high voltage transmit pulses in ultrasound applications and is commonly referred to as a T/R (transmit and receive) switch. Each channel has three terminals; Tx, Rx, and RGND. The analog switch terminals are Tx and Rx. Rx has integrated clamping diodes to RGND to protect the receiver against high voltages. Voltages greater than ±0.6V will start forward biasing the clamp diodes to RGND.
