74AC175SJ

Overview

The Fairchild Semiconductor 74AC175SJ is a quad D-type flip-flop belonging to the 74AC logic family. It features four independent circuits with single-ended inputs and differential outputs, housed in a 16-pin SOP package. The device operates within a supply voltage range of 2 V to 6 V and supports a propagation delay of 13 ns. It provides high drive capability with output currents of ±24 mA and functions reliably across an industrial temperature range from -40 °C to +85 °C.

Feature Summary

• Integrates four independent D-type flip-flops for parallel data storage applications
• Provides complementary (differential) outputs for enhanced signal integrity
• Supports wide supply voltage operation suitable for various logic levels
• Delivers high current drive capability for direct interface with loads

Applications

• Parallel data storage and buffering in digital systems
• Shift register construction for serial-to-parallel conversion
• State machine implementation in control logic circuits
• Timing and synchronization elements in clocked digital designs

Procurement Notes

Verify component authenticity through authorized distribution channels or official manufacturer documentation. Confirm that the specific part number matches the required 74AC series specifications and SOP-16 packaging. Ensure compliance with relevant environmental standards such as RoHS requirements before integration into final products.

Selection Notes

Select this component when requiring a quad D-type flip-flop with differential outputs and high drive strength. Consider the 74AC series characteristics for balanced speed and power consumption. Verify that the operating voltage range and temperature specifications align with the target application environment and system constraints.

Part Context

This component belongs to the 74AC family of CMOS logic devices, known for high-speed operation and compatibility with standard TTL interfaces. The 74AC175 variant specifically provides four D-type flip-flops with complementary outputs, distinguishing it from single-output variants like the 74AC74.
