HV2201FG-G集成电路（IC）的模拟开关-特殊用途规格书PDF中文资料

General Description

The Supertex HV2201 is a low charge injection, 8-channel, high voltage analog switch integrated circuit (IC). The device can be used in applications requiring high voltage switching controlled by low voltage control signals, such as medical ultrasound imaging, piezoelectric transducer drivers, and printers. The HV2201 is an enhanced version of the HV20220.

Input data is shifted into an 8-bit shift register that can then be retained in an 8-bit latch. To reduce any possible clock feed through noise, the latch enable bar should be left high until all bits are clocked in. Data is clocked in during the rising edge of the clock. Using HVCMOS technology, this device combines high voltage bilateral DMOS switches and low power CMOS logic to provide effcient control of high voltage analog signals.

The device is suitable for various combinations of high voltage supplies, e.g., VPP/VNN: +40V/-160V, +100V/-100V, and +160V/- 40V.
