CY74FCT273ATSOCT

Overview

The CY74FCT273ATSOCT is an octal D-type flip-flop with clear, manufactured by Texas Instruments. It belongs to the FCT logic series and features CMOS outputs with TTL-compatible inputs. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports surface-mount installation in an SOIC-20 package. It exhibits a propagation delay of 5.8 ns, with high-level output current capability of -32 mA and low-level output current of 64 mA. The component functions across a temperature range from -40°C to +85°C.

Feature Summary

• Octal D-type flip-flop architecture with dedicated clear function
• CMOS outputs compatible with TTL input levels
• High drive strength for reliable signal transmission

Applications

• Parallel data storage in digital systems
• Register file implementation
• Data bus interface circuits

Procurement Notes

Verify the specific suffix 'ATSOCT' against official Texas Instruments documentation to confirm tape-and-reel packaging and automotive-grade temperature rating. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target application design.

Selection Notes

Select this component when an octal register with a global clear function is required. The FCT series provides speed comparable to LS-TTL with lower power consumption. Consider the SOIC-20 package size and the specific current drive requirements for the connected loads.

Part Context

This part is part of the CY74FCT273T family of octal D-type flip-flops. It serves as a standard memory element in digital logic designs, offering eight independent D-type latches triggered by a common clock edge with a synchronous or asynchronous clear depending on the specific variant configuration.

Replacement Considerations

Check for CY74FCT273CTSOC or CY74FCT273ATSOC if different packaging or temperature grades are acceptable. Verify pin compatibility and electrical parameter equivalence before substitution.
