SN74BCT574DBRG4

Flip Flops Overview

The SN74BCT574DBRG4 is an octal edge-triggered D-type flip-flop manufactured by Texas Instruments. It features three-state outputs and is housed in a 20-pin SSOP package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a maximum propagation delay of 13 ns at 5 V, with low-level output current capability of 24 mA and high-level output current of -12 mA. The input type is TTL-compatible, and the polarity is non-inverting. The component supports surface-mount installation and functions across a temperature range of 0°C to +70°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops on a single chip
• Three-state outputs designed for direct bus driving applications
• TTL-compatible inputs ensuring compatibility with standard logic families
• Non-inverting polarity maintaining signal direction through the latch

Flip Flops Applications

• Buffer registers for data storage and transfer
• I/O port interface circuits
• Bidirectional bus drivers
• Working registers in digital systems

Flip Flops Procurement Notes

Verify the specific ordering suffix 'G4' confirms RoHS compliance and manufacturing origin details as per the manufacturer's datasheet. Ensure the SSOP-20 package dimensions match the target PCB footprint requirements. Confirm that the operating temperature range of 0°C to +70°C aligns with the environmental conditions of the intended application before finalizing procurement.

Flip Flops Selection Notes

Select this component when an octal latch with three-state outputs is required for bus-oriented memory or register applications. The BCT series offers improved performance over standard 74HC devices while maintaining TTL input compatibility. Consider the 20-pin SSOP package for surface-mount assembly constraints. Verify that the 4.5 V to 5.5 V supply voltage range matches the system power architecture.

Flip Flops Part Context

This part belongs to the Texas Instruments SN74BCT family of logic integrated circuits. The BCT series combines the speed of advanced CMOS technology with TTL input compatibility. The SN74BCT574 specifically provides octal edge-triggered functionality, distinguishing it from latches like the SN74BCT573 which are level-sensitive. It serves as a core building block for sequential logic design in industrial and commercial electronics.

Flip Flops Replacement Considerations

Public confirmed substitute part numbers include SN74BCT574DW, SN74BCT574DWR, and SN74BCT574N. These variants share identical logical functionality but differ in package type (SOIC, TSSOP, or DIP) or reel specifications. Verify pinout compatibility and electrical characteristics before substitution.
