FAQs
What is HEF4752VP?
The HEF4752VP is a 16-bit static shift register/latch with 3-state output, designed by NXP Semiconductors. It is commonly used in digital systems for parallel-in to serial-out conversion and can provide versatility and flexibility in interfacing with other digital devices.
How Does HEF4752VP Work?
The HEF4752VP operates by receiving parallel input data and shifting it out serially. It is designed to latch the input data and then output it in a serial manner, making it suitable for applications such as LED display drivers, shift registers, and serial data transfer.
How Many Pins does HEF4752VP have and What are the Functions of the Pinout Configuration?
The HEF4752VP is housed in a 24-pin TSSOP (Thin Shrink Small Outline Package) package. The pinout configuration includes:
- QA-QP: 16 parallel data input/output pins.
- CLK, MR, OE: Clock, master reset, and output enable control pins.
- SIN: Serial data input pin.
- SOUT: Serial data output pin.
- SH/LD: Shift/load control pin for selecting shift or load mode.
- VCC, GND: Power supply and ground pins.
What are the Pros and Cons of HEF4752VP?
Pros:
- 16-Bit Parallel-to-Serial Conversion: Offers efficient parallel data processing and serial data output.
- 3-State Output: Allows flexible interfacing with other devices and bus systems.
