MC74HC75FL2

Latches Overview

The MC74HC75FL2 is a high-speed silicon-gate CMOS device belonging to the 74HC series, manufactured by onsemi. It functions as a quad bistable transparent latch, providing four independent latches within a single package. The device features two active HIGH enable inputs that simultaneously control pairs of latches, allowing data to enter and appear at outputs when enabled. It is designed for low-power dissipation applications and complies with JEDEC standard no. 7A. The component offers ESD protection exceeding specified thresholds for human body model and machine model standards, ensuring robustness in various electronic environments.

Latches Feature Summary

• Quad bistable transparent latch architecture with simultaneous dual enable control
• High-speed silicon-gate CMOS technology compatible with low power Schottky TTL pinouts
• Complementary Q and non-Q outputs for each latch stage
• Integrated ESD protection meeting stringent industrial reliability standards

Latches Applications

• Data storage circuits requiring parallel input retention
• Interface logic between microprocessors and peripheral devices
• Memory buffer stages in digital signal processing systems

Latches Procurement Notes

Verify the specific suffix FL2 against the official onsemi datasheet to confirm package type and tape/reel specifications. Ensure compliance with RoHS directives if required for your assembly process. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability and authenticity. Check for any recent obsolescence notices or lifecycle status updates directly from the manufacturer before finalizing procurement plans.

Latches Selection Notes

Select this component when a compact solution for quadruple latching is required in space-constrained designs. Consider its compatibility with 5V logic families due to HC series characteristics. Evaluate the enable input configuration to ensure it matches the system's control signaling requirements. Verify operating temperature ranges align with the intended environmental conditions of the final application.

Latches Part Context

This part belongs to the broader 74HC family of logic integrated circuits, widely used in general-purpose digital electronics. The 74HC series is known for balancing speed and power consumption, making it suitable for battery-operated and high-density logic applications. As a latch variant, it serves foundational roles in sequential logic design, distinct from combinational gates like inverters or buffers found in other series members.

Latches Replacement Considerations

Compatible substitutes include the NXP Semiconductors 74HC75 and Nexperia 74HC75, which share identical functional descriptions and pinouts. These alternatives offer similar electrical characteristics and compliance with JEDEC standards. Verify package dimensions and marking codes to ensure mechanical interchangeability without redesigning the PCB footprint.
