FAQs
What is HV9123NG?
The HV9123NG is a high-voltage, 16-channel serial to parallel converter designed by Microchip Technology. It is suitable for applications requiring efficient and precise conversion of serial data to parallel outputs, such as industrial automation, LED display control, and automotive electronics.
How Does HV9123NG Work?
The HV9123NG works by receiving serial data input and converting it into 16 parallel output channels with high voltage capability. It utilizes internal shift registers and latches to capture the serial data and then updates the parallel outputs simultaneously, allowing for fast and synchronous operation. The converter operates with high voltage tolerance, making it suitable for driving various loads directly.
How Many Pins does HV9123NG have and What are the Functions of the Pinout Configuration?
The HV9123NG is housed in a 28-pin SSOP (Shrink Small Outline Package) package. The pinout configuration includes:
- VDD: Positive power supply pin.
- VSS: Ground pin.
- VDDP: High voltage power supply pin for the outputs.
- SDI: Serial data input pin.
- CLK: Clock input pin for serial data shifting.
- LE: Latch enable pin for updating parallel outputs.
- O0 - O15: Parallel output pins for the 16 channels.
What are the Pros and Cons of HV9123NG?
Pros:
- High Voltage Capability: Capable of driving high voltage loads directly, reducing the need for external drivers.
- Efficient Serial-to-Parallel Conversion: Provides fast and synchronous conversion of serial data to parallel outputs.
- Integrated Latches: Internal latches ensure simultaneous updating of the parallel outputs for precise control.
- Compact Package: The 28-pin SSOP package offers a space-efficient solution for high-channel count applications.
Cons:
- Complexity: High-voltage design considerations and layout requirements may add complexity to the system implementation.
- Power Dissipation: High voltage operation may lead to increased power dissipation, necessitating proper thermal management.
- External Components: May require external components such as level shifters or protection circuitry for specific applications.
Are There Any Equivalents/Alternatives to HV9123NG for Recommendation?
- The HV5812 from Supertex is a similar high-voltage, 16-channel serial to parallel converter.
- Alternatives to the HV9123NG include the TLC59283 from Texas Instruments and the MAX6971 from Maxim Integrated.
