HV2662LA-G

Analog Switches - Special Purpose Overview

The HV2662LA-G is a 24-channel high-voltage analog switch IC manufactured by Microchip Technology. It features a 24-bit serial shift register with latches for control, operating on 3.3V or 5.0V CMOS logic levels. The device utilizes HVCMOS technology to handle dual supplies ranging from -160V to +160V. Key electrical parameters include a maximum ON-resistance of 30 Ohms at 1A load, a typical OFF-isolation of -60 dB at 5 MHz, and a data shift clock frequency up to 20 MHz. It operates within an ambient temperature range of 0°C to +70°C.

Analog Switches - Special Purpose FAQ

Does the HV2662 have integrated bleed resistors?

No, the HV2662 does not have integrated bleed resistors. The HV2762 variant provides these resistors to eliminate voltage build-up on capacitive loads.

What is the maximum data shift clock frequency?

The maximum data shift clock frequency is 20 MHz when operating at a VDD of 5.0V.

How is the latch-enable bar used to reduce noise?

To reduce clock feedthrough noise, the latch-enable bar should be left high until all bits are clocked in during the rising edge of the clock.
