• High-speed performance supporting frequencies up to 150 MHz

Flip Flops Applications

• Bus-oriented memory register implementations
• Clock distribution circuits requiring parallel data capture
• Control logic interfaces in portable battery-powered devices
• Data acquisition systems utilizing low-voltage microprocessors

Flip Flops Procurement Notes

Verify the specific ordering suffix 'DTR2G' to ensure the correct tape-and-reel packaging quantity and RoHS compliance status. Confirm that the TSSOP-20 footprint matches the target PCB design. Cross-reference the manufacturer part number against official onsemi documentation to validate the 3-state output functionality and voltage specifications before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when designing systems requiring multiple flip-flops in a single package with low power consumption. The 3-state output feature makes it suitable for shared bus architectures. Ensure the system voltage remains within the 2.0 V to 3.6 V range to maintain signal integrity. Consider the 8.5 ns propagation delay for timing-critical applications involving high-speed data transfer.

Flip Flops Part Context

This device belongs to the 74LCX series of low-voltage CMOS logic ICs. It serves as a digital storage element within broader logic families, offering compatibility with standard TTL levels while operating at reduced voltages. The octal architecture distinguishes it from dual or quad variants, providing higher integration density for complex digital designs.

Flip Flops Replacement Considerations

Compatible substitutes include the MC74LCX574MTCX (SOIC-20 package) and MC74LCX574DT (TSSOP-20 package). Verify pinout compatibility and electrical characteristics such as propagation delay and output current when substituting.
