HV507PG-G

Shift Registers Overview

The HV507PG-G is a low-voltage to high-voltage serial-to-parallel converter featuring 64 push-pull outputs. It operates with a logic supply voltage (VDD) ranging from 4.5 V to 5.5 V and supports a high-voltage supply (VPP) up to 300 V. The device includes a 64-bit static shift register, latches, and control logic for polarity selection and output blanking. It functions at clock frequencies up to 8 MHz with a propagation delay of 125 ns. The component is housed in an 80-lead PQFP package and operates within an ambient temperature range of 0°C to +70°C.

Shift Registers Procurement Notes

Verify the specific ordering suffix 'G' indicates lead-free and RoHS-compliant packaging when placing orders. Confirm the media type corresponds to tray packaging for the PG package variant. Ensure compatibility with the required operating temperature range and power dissipation limits during system design validation.

Shift Registers Selection Notes

Select this component for designs requiring conversion of serial CMOS signals to parallel high-voltage drive capabilities. Evaluate the maximum output voltage requirements against the 300V limit. Consider the 80-lead PQFP footprint constraints and thermal management needs associated with the specified power dissipation rating.

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 at logic high, it shifts from HVOUT1 to HVOUT64.

What is the function of the LE input?

The Latch Enable (LE) input transfers data from the shift register to the latches. Data is stored in the latches during the transition of LE from high to low.
