描述 Description

This device is a low charge injection, 8-channel, high-voltage analog switch integrated circuit (IC) intended for use in applications requiring high voltage switching controlled by low voltage control signals, such as ultrasound imaging and printers.Input data is shifted into an 8-bit shift register which can then be retained in an 8-bit latch. To reduce any possible clock feed-through noise, Latch Enable Bar (LE) should be left high until all bits are clocked in. Using HVCMOS? technology, this switch combines high voltage bilateral DMOS switches and low power CMOS logic to provide efficient control of high voltage analog signals.These ICs are suitable for various combinations of high voltage supplies, e.g., VPP/VNN : +50V/-150V, or +100V/-100V.

簡介

HV20220屬于集成電路（IC）的模擬開關(guān)-特殊用途。由制造生產(chǎn)的HV20220模擬開關(guān) - 特殊用途特殊用途模擬開關(guān)通過固態(tài)設(shè)備路由模擬信號。該系列產(chǎn)品的與眾不同之處在于，這些模擬開關(guān)針對特定的應(yīng)用，因此具有通用模擬開關(guān)通常所沒有的獨特功能。
