Vue d'ensemble

Description

The 74LVC595APW is an 8-bit shift register with an output latch, designed for efficient serial-to-parallel data conversion. It operates on a wide voltage range of 2.3V to 5.5V, making it suitable for various low-voltage applications. The device features a serial data input (DS), a shift clock (SHCP), and a storage clock (STCP), allowing users to shift in data serially and then latch it to the output pins (Q0 to Q7).
This IC is part of the LVC series, which stands for Low Voltage CMOS, providing low power consumption and high-speed performance. It supports high-speed data transfer rates, making it ideal for interfacing with microcontrollers or digital systems that require expansion of output pins. The 74LVC595APW is often used in applications such as LED displays, data multiplexing, and other digital logic integration tasks. Additionally, it has a tri-state output feature, enabling multiple devices to share the same data bus without conflicts.

Features

The 74LVC595APW is an 8-bit serial-in, parallel-out shift register with a 3-state output. Key features include:
1. 8-Bit Storage: It can store 8 bits of data.
2. Serial Input: Data is entered serially, allowing for reduced pin count.
3. Parallel Output: Outputs can be accessed simultaneously, enabling efficient data handling.
4. High-Speed Operation: It operates at a wide range of clock frequencies (up to 100 MHz).
5. Low Power Consumption: Designed for low power operation, making it suitable for battery-powered applications.
6. 3.3V Compatible: It supports 3.3V CMOS logic levels, with a wide input voltage range.
7. Shift Register Functionality: Features a shift register for data manipulation and transfer.
8. Output Enable Control: Allows for control of output states (high impedance) to facilitate device cascading.
9. Temperature Range: Operates across a standard temperature range of -40°C to +125°C.
These features make the 74LVC595APW ideal for various digital applications, such as LED control and data communication interfaces.

Package

The 74LVC595APW is housed in a TSSOP (Thin Shrink Small Outline Package) with 16 pins. Its specific package code is "PW," indicating a width of 4.4 mm and a height of 1.0 mm, suitable for surface-mount applications.

Pinout

The 74LVC595APW is an 8-bit shift register with a serial input and parallel output. It features a total of 16 pins. The pin functions are as follows:
1. QA to QH (Pins 15-8): Parallel output pins (Q0 to Q7).
2. SRCLR (Pin 1): Shift register clear; active low.
3. SRCK (Pin 2): Shift register clock input; data is shifted on the rising edge.
4. RCLK (Pin 3): Register clock input; transfers the shifted data to the output on the rising edge.
5. SER (Pin 4): Serial data input.
6. OE (Pin 5): Output enable; active low (outputs are enabled when low).
7. VCC (Pin 6): Power supply pin (typically 2.3V to 5.5V).
8. GND (Pin 11): Ground pin.
9. NC (Pins 7, 9, 10): No connect (not used).
The device is commonly used in applications requiring data storage and manipulation, such as LED driving and digital signal processing.
