Part Name(s) : HV230G1-G SUTEX
Supertex Inc
Description : Low Charge Injection, 8-Channel, High Voltage Analog Switches with Bleed Resistors View

General Description

The Supertex HV230 is a Low Charge Injection 8-Channel, High-Voltage, Analog switch integrated circuit (IC) with Bleed Resistors. This device can be used in applications requiring High Voltage switching controlled by Low Voltage control signals, such as ultrasound imaging and printers. The Bleed Resistors eliminate Voltage built up on capacitive loads such as piezoelectric transducers. 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 (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.



Features

► HVCMOS® technology for High performance

► Very Low quiescent power dissipation (-10µA max.)

► Output on-resistance typically (22Ω typ.)

► CMOS logic circuitry for Low power

► Excellent noise immunity

► ON-chip shift register, latch and clear logic circuitry

► Flexible High Voltage supplies



Applications

Description : Micropower, Low Charge Injection, Quad CMOS Analog Switches View

DESCRIPTION

The LTC® 201A, LTC202, and LTC203 are micropower, quad CMOS Analog Switches which typically dissipate only 250µW from ±15V supplies and 40µW from a single 5V supply. The Switches have 65Ω typical on resistance and a very High off resistance. A break-before-make characteristic, inherent in these Switches, prevents the shorting of two channels. with a supply Voltage of ±15V, the signal range is ±15V. These Switches have special Charge compensation circuitry which greatly reduces Charge Injection to a maximum of ±25pC (±15V supplies).



FEATURES

■ Micropower Operation

■ Single 5V or ±15V Supply Operation

Low Charge Injection

Low RON

Low Leakage

■ Guaranteed Break Before Make

■ Latch Resistant Design

■ TTL/CMOS Compatible

■ Improved Second Source for DG2O1A/DG202
