SN74ABT823NSRE4

Flip Flops Overview

The SN74ABT823NSRE4 is an octal D-type edge-triggered flip-flop manufactured by Texas Instruments, belonging to the ABT logic series. It features non-inverting outputs with three-state control and accepts TTL-compatible inputs. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 6.6 ns, a high-level output current of -32 mA, and a low-level output current of 64 mA. It supports surface-mount installation in an SOIC-20 package and functions reliably across a temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type edge-triggered flip-flops for parallel data storage.
• Three-state outputs enable direct connection to system buses without additional buffering hardware.
• Non-inverting polarity ensures logical consistency between input signals and stored output states.

Flip Flops Applications

• Parallel data storage registers in digital communication systems
• Buffering and latching operations on microprocessor-based data buses
• High-speed timing control circuits requiring precise clock-edge triggering

Flip Flops Procurement Notes

Verify that the specific ordering suffix 'E4' aligns with your project's environmental compliance requirements, as it indicates RoHS-compliant manufacturing standards. Confirm that the SOIC-20 surface-mount package matches your PCB footprint design and soldering capabilities. Ensure the 4.5 V to 5.5 V operating voltage range is compatible with your system's power distribution network before finalizing procurement.

Flip Flops Selection Notes

Select this component when designing systems requiring high-density octal data storage with fast switching speeds. The ABT series offers superior performance compared to standard 74LS logic, making it suitable for applications demanding propagation delays under 7 ns. Consider the three-state capability if bus sharing is required, and verify that the TTL input thresholds meet your interface voltage levels.

Flip Flops Part Context

This part belongs to the SN74ABT family of advanced bipolar-transistor logic devices from Texas Instruments. The ABT series combines the speed of Schottky technology with CMOS power efficiency. As an octal flip-flop, it serves as a fundamental building block for sequential logic circuits, distinguishing itself from buffer drivers like the SN74ABT240 or single-channel variants.
