HV3418PG-G

Shift Registers Overview

The HV3418PG-G is a 64-channel serial-to-parallel converter with high-voltage push-pull outputs, manufactured by Microchip Technology. It operates within a logic supply voltage range of 4.5V to 5.5V or 10.8V to 13.2V, and supports a high-voltage supply up to 180V. The device features a 64-bit static shift register and latches, enabling data shifting speeds of up to 6 MHz at 5V and 12 MHz at 12V. It utilizes an 80-lead PQFP package and functions across an ambient temperature range of -40°C to +85°C.

Shift Registers FAQ

How does the DIR pin affect data flow?

The DIR pin controls the direction of data shifting. When grounded, data shifts from HVOUT64 to HVOUT1; when set to logic high, it shifts from HVOUT1 to HVOUT64.

What is the maximum high-voltage supply capability?

The device supports a high-voltage supply (VPP) up to 180V under recommended operating conditions.
