SN74LS374DWR2

Flip Flops Overview

The SN74LS374DWR2 is an octal D-type edge-triggered flip-flop manufactured by onsemi, housed in a 20-SOIC surface-mount package. It operates within a supply voltage range of 4.75 V to 5.25 V and supports a maximum clock frequency of 50 MHz. The device features non-inverting outputs with a propagation delay of 28 ns at 5 V with 45 pF load. Output drive capabilities include a high-level current of -2.6 mA and a low-level current of 24 mA. It functions within a temperature range of 0°C to +70°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type edge-triggered flip-flops in a single integrated circuit.
• Three-state outputs designed for direct connection to bus-organized systems without requiring interface components.
• Totem-pole output structure optimized for driving highly capacitive or relatively low-impedance loads.

Flip Flops Applications

• Implementation as buffer registers in digital logic circuits
• Configuration as I/O ports for data interface applications
• Utilization as bidirectional bus drivers in system architectures

Flip Flops Procurement Notes

Verify the manufacturer designation carefully, as the part number prefix 'SN' typically indicates Texas Instruments, while this specific listing identifies onsemi as the producer. Confirm RoHS compliance status, as source data indicates non-compliance for this variant. Ensure the SOIC-20 package dimensions match the target PCB footprint requirements before integration into the design.

Flip Flops Selection Notes

Select this component when an octal register with three-state outputs is required for bus-driven applications. The LS logic family provides specific drive characteristics suitable for moderate-speed interfaces up to 50 MHz. Consider the operating temperature range of 0°C to +70°C against environmental conditions. Evaluate the 28 ns propagation delay against system timing constraints to ensure signal integrity.

Flip Flops Part Context

This device belongs to the 74LS374 series of octal D-type flip-flops. It shares functional similarities with other octal registers like the MC74ACT374DWR2G but differs in logic family technology and electrical specifications. The SN74LS374DWR2 represents a legacy LS variant, distinct from HC or ACT families in terms of speed and power consumption profiles.
