74LS374P-E

Overview

The Renesas 74LS374P-E is an octal D-type flip-flop featuring three-state outputs, designed for bus-oriented applications. It operates within a standard voltage range and supports high-speed data transfer with low power consumption typical of the LS logic family. The component utilizes positive edge-triggered clocking to capture input data at eight independent D inputs. Outputs provide true logic states and can drive loads directly when enabled. The device includes buffered clock and output enable lines common to all flip-flops, ensuring synchronized operation across the octet.

Feature Summary

• Octal D-type flip-flop architecture with separate inputs for each stage

Procurement Notes

Verify the exact package type and pin configuration against the official datasheet before integration. Confirm that the supply voltage levels match the LS logic requirements. Check for any specific handling instructions regarding electrostatic discharge during assembly. Ensure the operating temperature range aligns with the intended application environment. Cross-reference the ordering suffix to confirm availability and manufacturing status.

Selection Notes

Select this component when an octal latch with three-state capability is required for bus systems. Consider the propagation delay characteristics relative to system timing constraints. Evaluate power dissipation limits if multiple units are used in close proximity. Compare performance metrics with alternative logic families if lower power or higher speed is needed. Verify compatibility with existing clock and control signals.
