74HCT175PW,112

Overview

The 74HCT175PW,112 is a quad D-type flip-flop manufactured by Nexperia USA Inc. It belongs to the HCT logic family, ensuring TTL-compatible input levels while operating with CMOS output drive capabilities. The device features four independent D inputs and corresponding Q outputs, along with complementary nQ outputs. It includes an asynchronous active-LOW master reset (MR) input that overrides clock and data signals. The component is designed for surface-mount applications in a 16-TSSOP package.

Feature Summary

• Quad D-type edge-triggered flip-flops with separate data inputs
• Asynchronous active-low master reset functionality
• TTL-compatible input voltage thresholds for direct interfacing
• Complementary Q and nQ outputs for flexible logic design

Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations for data storage
• State retention in digital control systems
• Synchronization of asynchronous signals

Procurement Notes

Verify the specific suffix '112' against current Nexperia documentation to confirm tape-and-reel packaging specifications. Confirm availability status as distribution channels may list obsolete or limited stock variants. Ensure the selected distributor provides valid RoHS compliance certificates matching the manufacturing date code. Cross-reference the ordering part number with the official datasheet to avoid confusion with similar HC or PW variants.

Selection Notes

Select this component when TTL-level interface compatibility is required within a CMOS system architecture. The HCT series ensures reliable operation with standard 5V logic supplies while maintaining low power consumption. Consider the 16-TSSOP package for space-constrained PCB layouts requiring surface-mount technology. Verify that the asynchronous reset requirement aligns with the system's initialization sequence needs.

Part Context

This part is a member of the Nexperia 74HCT logic family, which bridges the gap between older TTL standards and modern CMOS technologies. The 74HCT175 variant specifically provides quadruple flip-flop functionality, distinct from single or dual flip-flop counterparts like the 74HCT74. It is widely used in industrial and consumer electronics where robust noise immunity and standardized pinouts are essential for modular design.

Replacement Considerations

Public confirmed substitute part numbers include 74HCT175D,652 and 74HCT175PW,118. These alternatives offer identical logical functionality and pinout compatibility. Verify package dimensions and electrical characteristics match the original design requirements before substitution.
