概述

Description

The SN74AHC595PWR is an 8-bit serial-in, serial or parallel-out shift register designed for high-speed applications. It operates on a wide supply voltage range (2 V to 6 V) and features low power consumption, making it suitable for battery-operated devices. The device consists of an 8-bit shift register, a storage register, and an output driver.
Key features include a serial data input for shifting data in, a clock input for synchronizing data shifts, and outputs that can be used in parallel. It has a latch function that allows the stored data to be accessed without disturbing the shift register, which is advantageous for managing multiple devices with limited I/O lines.
The SN74AHC595PWR is commonly used in applications such as LED control, data transmission, and interfacing with microcontrollers. Its package type (TSSOP-16) ensures a compact design for space-constrained projects, while its compatibility with standard CMOS logic levels allows for easy integration into various electronic systems.

Features

The SN74AHC595PWR is an 8-bit shift register with an output latching feature, designed for high-speed applications. Key features include:
1. 8-Bit Shift Register: Allows serial-in, parallel-out data storage with eight output pins.
2. Latching Outputs: Outputs can be latched to retain their state, ensuring stability in data presentation.
3. High-Speed Operation: Capable of operating at speeds up to 110 MHz, ideal for fast data processing.
4. Wide Voltage Range: Operates with a supply voltage from 2V to 6V, making it versatile for different applications.
5. Low Power Consumption: Designed for low power usage, making it suitable for battery-operated devices.
6. TTL Compatible: Compatible with TTL logic levels, facilitating integration with other digital circuits.
7. Shift and Store Functions: Supports both shifting data in and storing it for output.
8. Serial Data Input: Accepts data serially for efficient data handling.
These features make the SN74AHC595PWR suitable for applications in microcontroller interfacing, LED control, and more.

Package

The SN74AHC595PWR is housed in a TSSOP (Thin Shrink Small Outline Package) with a package type of TSSOP-20.

Pinout

The SN74AHC595PWR is an 8-bit shift register with a serial input, parallel output, and a pin count of 16. It features the following key functions:
1. Data Input (DS): Serial data input for shifting in bits.
2. Clock (SHCP): Clock input for shifting data on the rising edge.
3. Latch Clock (STCP): Latch input for transferring shifted data to output.
4. Output Enable (OE): Active low control for enabling/disabling outputs.
5. Reset (MR): Active low reset to clear the shift register contents.
6. Parallel Outputs (Q0-Q7): 8 parallel outputs corresponding to the stored bits.
7. Serial Output (Q7’): Outputs the last shifted bit for cascading multiple registers.
The device operates within a voltage range of 2V to 5.5V and is suitable for high-speed applications due to its AHC technology.
