74ACT74SCX_SF86787A

Flip Flops Overview

The onsemi 74ACT74SCX is a dual D-type flip-flop featuring independent preset and clear inputs. It utilizes advanced silicon-gate CMOS technology to achieve operating speeds comparable to equivalent LS-TTL parts while maintaining high noise immunity and low power consumption. The device operates within a supply voltage range of 4.5V to 5.5V and supports clock frequencies up to 94MHz. It provides Q and complementary outputs with a fanout capability of 10 LS-TTL loads, housed in a surface-mount SOIC-14 package.

Flip Flops Feature Summary

• Advanced silicon-gate CMOS technology for high-speed operation
• Independent data, preset, clear, and clock inputs
• High noise immunity and low power consumption
• TTL-compatible input levels

Flip Flops Applications

• Parallel-to-serial data conversion

Flip Flops Procurement Notes

Verify the specific suffix SF86787A against official manufacturer documentation to confirm exact packaging or tape-and-reel specifications. Ensure compatibility with standard SOIC-14 footprints during PCB layout. Confirm that the logic family matches system requirements for voltage levels and drive strength before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when a dual D-type flip-flop with fast switching speeds is required. It is suitable for designs needing direct replacement for LS-TTL equivalents without voltage level shifting. Consider the 20ns propagation delay and 94MHz maximum frequency for timing-critical digital logic applications requiring robust noise immunity.

Flip Flops Part Context

This part belongs to the 74ACT logic family, which bridges the performance gap between standard CMOS and Low-power Schottky TTL. The 74ACT74 variant specifically integrates two D-type flip-flops with set and reset capabilities, widely used in sequential logic circuits where precise data latching and synchronization are essential for system stability.

Flip Flops Replacement Considerations

Functionally compatible with MC74ACT74SCX. Verify pinout alignment with other 74ACT74 variants from different manufacturers to ensure interchangeability in existing designs.
