MC74LCX374DWR2

Flip Flops Overview

The MC74LCX374DWR2G is an octal D-type flip-flop from the onsemi 74LCX logic family, designed for low-voltage CMOS applications. It features eight positive-edge-triggered D-type flip-flops with three-state outputs in a 20-pin SOIC package. The device operates within a supply voltage range of 2V to 3.6V, ensuring compatibility with modern low-power systems. Key electrical parameters include a maximum propagation delay of 8.5ns at 3.3V with 50pF load, a clock frequency capability of 150MHz, and output drive currents of ±24mA. Static current consumption is typically 10µA, while input capacitance is rated at 7pF. The component supports surface-mount installation and functions reliably across an operating temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops with positive-edge triggering for parallel data storage.
• Three-state non-inverting outputs enable direct bus-oriented connections without requiring interface buffers.
• Low power consumption characteristics with minimal static current draw suitable for battery-operated devices.
• High-speed performance with 150MHz clock frequency and fast propagation delays for efficient data transfer.

Flip Flops Applications

• Parallel-to-serial and serial-to-parallel data conversion circuits
• Buffering and register designs in low-voltage digital systems
• Clock domain crossing interfaces for synchronization
• Memory address latching in portable electronic devices

Flip Flops Procurement Notes

Verify the complete part number includes the suffix 'G' indicating RoHS compliance when ordering. Confirm package variant matches design requirements as the DWR2G denotes a specific 20-SOIC width. Check manufacturer documentation for moisture sensitivity level handling procedures prior to assembly. Ensure supply chain sources provide valid traceability records for quality assurance purposes.

Flip Flops Selection Notes

Select this component for designs requiring low voltage operation between 2V and 3.6V with high-speed data handling capabilities. Consider the 150MHz clock limit and 8.5ns propagation delay for timing-critical paths. Evaluate the ±24mA output drive strength against load requirements. Compare against other 74LCX variants if different packaging or voltage ranges are needed for the specific application constraints.

Flip Flops Part Context

This device belongs to the 74LCX374 family of octal D-type flip-flops manufactured by onsemi. It is part of the broader 74LCX logic series characterized by ultra-low power and high speed performance. The standard product identifier often appears with the 'G' suffix for environmental compliance. It serves as a fundamental building block for sequential logic in mixed-signal and digital-only integrated circuit designs.

Flip Flops Replacement Considerations

MC74LCX374DTR2G offers the same logical function in a TSSOP-20 package instead of SOIC-20. MC74AC374MG provides similar functionality but operates at higher voltages up to 6V. SN74AC374NSR from Texas Instruments is a functional equivalent with comparable AC specifications. Verify pinout compatibility and voltage levels before substituting any alternative part numbers.
