概述

Description

The SN74LV165ADR is an 8-bit serial-in, parallel-out shift register designed for high-speed data processing in digital applications. It operates with a supply voltage range of 2V to 5.5V, making it suitable for low-voltage systems. The device features a serial input (DS) for shifting in data, a parallel output (Q0–Q7) for accessing the stored data simultaneously, and two control inputs: the clock (CLK) and the latch enable (LE).
Data is shifted into the register on the rising edge of the clock signal, allowing for efficient data transfer and storage. The LE pin controls when the shifted data is made available at the outputs. With its low power consumption and high-speed performance, the SN74LV165ADR is commonly used in applications like LED displays, data communication, and digital signal processing where parallel data output is required from serial inputs. Additionally, it is compatible with various logic families, ensuring versatility in design.

Features

The SN74LV165ADR is a high-speed 8-bit serial-in/parallel-out shift register. Key features include:
1. 8-Bit Storage: It can store 8 bits of data.
2. Serial Data Input: Data can be entered serially, allowing for efficient data transmission.
3. Parallel Data Output: The stored data can be accessed in parallel, enabling quick retrieval.
4. Low Voltage Operation: It operates from a supply voltage range of 2V to 6V, compatible with low-voltage logic.
5. High-Speed Performance: Capable of operating at frequencies up to 70 MHz, making it suitable for fast applications.
6. Active Low Outputs: The outputs are active low, which is useful in logic-level interfacing.
7. Cascade Capability: Multiple devices can be cascaded for expanded data handling.
8. Temperature Range: Designed to operate in a wide temperature range from -40°C to 125°C.
These features make the SN74LV165ADR ideal for applications such as data communication, microcontroller interfacing, and digital signal processing.

Package

The SN74LV165ADR is available in a 16-pin TSSOP (Thin Shrink Small Outline Package) format.

Pinout

The SN74LV165ADR is a 16-bit serial-in, parallel-out shift register. It features a total of 16 pins. The key functions of these pins are as follows:
1. Serial Data Input (DS): Pin for serial data input.
2. Clock Input (CLK): Triggers data shifting on the rising edge.
3. Latch Enable (LE): Controls when the output data is latched.
4. Output Enable (OE): Activates the output drivers when low.
5. Parallel Outputs (Q0 to Q15): Provides the parallel output of the shifted data.
6. Shift/Load Control (SH/LD): Selects between shifting in serial data and loading parallel data.
7. Reset (MR): Resets the internal state of the shift register.
The device operates at a wide range of supply voltages, making it suitable for various applications in digital circuits.
