SN74LVC574ADWRE4

Flip Flops Overview

The SN74LVC574ADWRE4 is an octal D-type flip-flop with 3-state outputs manufactured by Texas Instruments. It belongs to the LVC logic series and operates within a supply voltage range of 1.65V to 3.6V. The device features non-inverting polarity and accepts both CMOS and TTL input types. Packaged in a 20-SOIC surface-mount format, it exhibits a maximum propagation delay of 6.8ns at 3.3V with 50pF load. Output drive capability reaches 24mA for both high and low states, while static current consumption is typically 10µA. It supports clock frequencies up to 150MHz and functions reliably across a temperature range of -40°C to 125°C.

Flip Flops Procurement Notes

Verify the specific suffix 'E4' indicates lead-free manufacturing compliance consistent with RoHS standards. Confirm the SOIC-20 package dimensions match the target PCB footprint design constraints. Ensure the operating temperature range aligns with the intended environmental conditions. Cross-reference the datasheet revision history for any updates to electrical characteristics or pinout configurations prior to final procurement authorization.

Flip Flops Selection Notes

Select this component when designing systems requiring octal data storage with low-voltage operation capabilities. The LVC series offers superior speed compared to standard LV variants while maintaining lower power consumption than AC/ACT families. Consider the 24mA output drive strength for moderate capacitive loads. Verify that the 3-state outputs meet the bus isolation requirements of the specific application topology.

Flip Flops Part Context

This part is a member of the SN74LVC574A family, which provides octal edge-triggered D-type flip-flops. The 'E4' suffix specifically denotes a lead-free product variant compliant with European Union directives. It shares functional equivalence with other LVC574 packages but differs in physical form factor and packaging material composition compared to non-E4 counterparts.
