SN74ALS175DR

Flip Flops Overview

The SN74ALS175DR is a quad positive-edge-triggered D-type flip-flop manufactured by Texas Instruments in the ALS logic series. It features TTL-compatible inputs and outputs, housed in a 16-pin SOIC surface-mount package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a propagation delay of 17 ns. It is designed for through-hole or surface-mount installation with an operating temperature range from 0°C to +70°C.

Flip Flops Feature Summary

• Provides four independent positive-edge-triggered D-type flip-flops within a single integrated circuit
• Features TTL-compatible input and output structures for direct interfacing with standard logic families
• Includes a master reset function to initialize all flip-flop states simultaneously

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations for data storage and transfer
• General-purpose digital memory elements in microprocessor systems

Flip Flops Procurement Notes

Verify that the ordering suffix 'DR' corresponds to the SOIC-16 surface-mount package variant rather than the PDIP through-hole version. Confirm the specific manufacturer source matches the required quality standards. Ensure the component meets the specified ALS logic family characteristics and voltage requirements for the target application design.

Flip Flops Selection Notes

Select this component when a compact surface-mount solution for quad D-type flip-flops is required. The ALS series offers a balance of speed and power consumption suitable for general digital logic applications. Consider the SOIC-16 footprint constraints and ensure compatibility with existing PCB layout designs requiring 4.5V to 5.5V operation.

Flip Flops Part Context

This part belongs to the Texas Instruments SN74ALS175 series, which provides quad D-type flip-flops. The 'ALS' designation indicates Advanced Low-power Schottky technology, offering improved performance over standard 74LS devices. The 'DR' suffix specifically identifies the SOIC-16 surface-mount package option available from the manufacturer.
