SN74AS4374BNS

Flip Flops Overview

The SN74AS4374BNS is an octal D-type flip-flop manufactured by Texas Instruments, belonging to the Advanced Schottky (AS) logic family. It features eight independent positive-edge-triggered D-type flip-flops with three-state outputs and a master reset function. The device operates within a supply voltage range of 4.5 V to 5.5 V and utilizes a 20-pin SOIC surface-mount package. Key electrical characteristics include a propagation delay of 11.5 ns at 50 pF load, a high-level output current of 15 mA, and a low-level output current of 48 mA. It supports through-hole or surface-mount installation styles depending on variant configuration, with a specified operating temperature range from 0°C to +70°C.

Flip Flops Feature Summary

• Octal architecture containing eight independent positive-edge-triggered D-type flip-flops for parallel data storage applications.
• Three-state outputs enable direct bus driving connections without additional interface circuitry.
• Master reset input provides synchronous clearing of all flip-flops to a low state upon clock activation.
• Advanced Schottky technology delivers high-speed switching performance with reduced propagation delays.

Flip Flops Applications

• Parallel-to-serial data conversion circuits in communication systems
• High-speed register arrays for microprocessor memory interfaces
• Buffering stages in digital signal processing equipment
• State machine implementations requiring fast clock edge response

Flip Flops Procurement Notes

Verify the specific suffix designation against official Texas Instruments documentation to confirm exact pinout compatibility and package dimensions. Ensure that the procurement source provides valid RoHS compliance certificates if required by regulatory standards. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and authenticity before finalizing orders.

Flip Flops Selection Notes

Select this component when system requirements demand high-speed data latching with minimal propagation delay compared to standard TTL families. The three-state output capability makes it suitable for shared bus architectures where multiple devices must connect to common data lines. Consider thermal management requirements due to higher static currents associated with Advanced Schottky technology relative to lower-power alternatives.

Flip Flops Part Context

This component belongs to the SN74AS series, representing Texas Instruments' Advanced Schottky logic family designed for high-performance digital applications. It serves as a faster alternative to standard 74S series devices while offering improved speed-over-power characteristics. The octal configuration distinguishes it from quad variants, providing greater integration density for complex digital logic designs requiring multiple synchronized storage elements.
