SN74LVC574ARGYR

Flip Flops Overview

The SN74LVC574ARGYR is a D-type flip-flop from the Texas Instruments LVC logic series. It features eight non-inverting outputs with three-state capability, housed in a 20-VQFN package with exposed pad. The device operates within a supply voltage range of 1.65 V to 3.6 V. Key electrical parameters include a propagation delay of 6.8 ns at 3.3 V with 50 pF load, and output drive currents of ±24 mA. It supports clock frequencies up to 150 MHz and has an input capacitance of 4 pF. The component functions across a temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Provides octal edge-triggered data storage with non-inverting outputs
• Features three-state outputs for direct bus line interfacing
• Supports low-voltage operation down to 1.65 V
• Compatible with CMOS and TTL input levels

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register file implementations in embedded systems
• Bus buffer applications requiring high-speed transfer
• I/O port expansion for microcontrollers

Flip Flops Procurement Notes

Verify the specific suffix ARGYR to confirm the 20-VQFN package type and tape-and-reel packaging format. Ensure compatibility with surface-mount assembly processes. Confirm RoHS compliance status and moisture sensitivity level requirements for your manufacturing environment before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when designing low-voltage digital systems requiring high-speed octal latching. The 20-VQFN package offers a compact footprint suitable for space-constrained PCB layouts. Consider the 6.8 ns propagation delay and 150 MHz maximum frequency for timing-critical applications. Verify that the 24 mA drive current meets the load requirements of the connected circuitry.

Flip Flops Part Context

This part belongs to the SN74LVC574A family of octal D-type flip-flops. It shares functional similarities with other variants like the SN74LVC574ADBR (SSOP-20) and SN74LVC574APW (TSSOP-20), differing primarily in package style and reel configuration. The LVC series is designed for low-power consumption while maintaining high switching speeds compared to older logic families.

Flip Flops Replacement Considerations

Direct pin-compatible substitutes include SN74LVC574ADBR and SN74LVC574APW, though these utilize SSOP-20 and TSSOP-20 packages respectively. Verify footprint compatibility on the PCB layout. Other LVC series octal flip-flops may require schematic adjustments due to pinout differences.
