74F374SJ

Flip Flops Overview

The onsemi 74F374SJ is an obsolete octal D-type flip-flop housed in a 20-SOP package. It operates within a supply voltage range of 4.5V to 5.5V and features positive-edge triggered logic with tri-state, non-inverting outputs. The component supports a maximum clock frequency of 140 MHz and exhibits a maximum propagation delay of 8.5ns at 5V with 50pF load. Output drive capabilities include 3mA high-level and 24mA low-level current, while static current consumption is specified at 86 mA. It is designed for surface-mount installation across a commercial operating temperature range of 0°C to 70°C.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture providing eight independent data storage elements within a single integrated circuit.
• Positive-edge triggering mechanism ensures precise data capture synchronized with the rising edge of the clock signal.
• Tri-state output configuration allows direct connection to bus systems without requiring external interface or pull-up components.

Flip Flops Applications

• Buffer registers in digital data processing systems
• I/O port implementations for microcontroller interfaces
• Bidirectional bus drivers in organized system architectures

Flip Flops Procurement Notes

This component is officially classified as obsolete and no longer manufactured by onsemi. Procurement must rely on secondary market distributors or verified surplus stock. Verify part authenticity carefully due to potential availability of refurbished units. Confirm that the specific SOP-20 package variant matches design requirements before integration into new production cycles.

Flip Flops Selection Notes

Engineers should evaluate alternative active components from the same logic family or compatible manufacturers for new designs. Consider parameters such as propagation delay, output drive strength, and power consumption when selecting replacements. Ensure that any substitute device maintains compatibility with existing 5V logic levels and physical footprint constraints to facilitate seamless transition without redesigning the printed circuit board.

Flip Flops Part Context

The 74F374SJ belongs to the 74F series of high-speed logic devices produced by onsemi. This series utilizes advanced bipolar technology to achieve faster switching speeds compared to standard TTL counterparts. The component represents a specific variant within the broader octal flip-flop category, tailored for applications requiring rapid data latching and high-frequency operation within standard industrial temperature limits.

Flip Flops Replacement Considerations

Direct substitutes include SN74F374NSR and SN74F374DWR from Texas Instruments. These alternatives offer functional equivalence for legacy system upgrades where the original onsemi part is unavailable. Verify pinout compatibility and electrical specifications before implementation.
