74LVC574ADB,118

Overview

The 74LVC574ADB,118 is a single D-type flip-flop with positive-edge triggering, manufactured by Nexperia USA Inc. It operates within a supply voltage range of 1.2 V to 3.6 V and features non-inverting outputs. The device provides high noise immunity and includes Schmitt trigger action at all inputs. It is specified for operation from -40 °C to +125 °C and complies with JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C/JESD36. The component utilizes an SOIC-20 package.

Feature Summary

• Positive-edge triggered D-type flip-flop with non-inverting outputs
• Schmitt trigger inputs for tolerance of slow rise and fall times
• Wide supply voltage range supporting 1.2 V to 3.6 V operation
• Compliance with multiple JEDEC standards for various voltage levels

Applications

• Data storage and register applications in digital systems
• Interface between different logic families due to 5 V tolerant inputs
• High-speed data transfer circuits requiring positive-edge triggering
• Industrial control systems operating across wide temperature ranges

Procurement Notes

Verify the specific ordering code suffix against the manufacturer's official documentation to ensure correct package type and temperature grade. Confirm RoHS compliance status and REACH registration details prior to procurement. Cross-reference the datasheet revision history to validate current specifications and any potential packaging changes. Ensure compatibility with existing design constraints regarding input thresholds and output drive capabilities.

Selection Notes

Select this component when a single D-type flip-flop with positive-edge triggering is required in mixed-voltage environments. The Schmitt trigger inputs make it suitable for noisy industrial settings or signals with slow transition times. Consider the SOIC-20 package dimensions and thermal characteristics for PCB layout. Verify that the 1.2 V minimum supply voltage meets the system's lowest operating condition requirements.

Part Context

This part belongs to the 74LVC series of low-voltage CMOS logic devices. It is functionally similar to other 74LVC574 variants but differs in package configuration. The 'ADB' suffix typically denotes a specific tape and reel or cut tape option within the SOIC-20 family. It serves as a standard building block for sequential logic circuits in modern embedded systems.

Replacement Considerations

Direct substitutes include 74LVC574AD,118 and 74LVC574APW,118, provided the package form factor matches the design requirements. Verify pinout compatibility and electrical parameters before substitution. Alternative packages such as TSSOP or QFN may require mechanical redesign.
