SN74ALS576BNSR

Flip Flops Overview

The SN74ALS576BNSR is an octal D-type edge-triggered flip-flop from the Texas Instruments ALS logic series, housed in a 20-pin SOIC package. It features three-state outputs and TTL inputs with inverting polarity. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports surface mount installation. Key electrical parameters include a propagation delay of 14 ns, a high-level output current of -2.6 mA, and a low-level output current of 24 mA. It functions reliably across an operating temperature range of 0°C to +70°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type edge-triggered flip-flops within a single integrated circuit.
• Three-state outputs enable direct connection to bus-oriented systems without additional interface hardware.
• TTL-compatible inputs ensure logical compatibility with standard transistor-transistor logic families.
• Inverting polarity design allows for specific signal path requirements in digital data storage applications.

Flip Flops Applications

• Bus-oriented memory register implementations
• Parallel-to-serial data conversion circuits
• High-speed digital signal processing interfaces
• Computer system control logic modules

Flip Flops Procurement Notes

Verify that the ordering suffix matches the required package type and tape/reel specifications. Confirm RoHS compliance status aligns with project environmental regulations. Ensure the manufacturer identification corresponds to Texas Instruments to guarantee component authenticity and performance consistency.

Flip Flops Selection Notes

Select this component when an octal storage solution with three-state capability is required for bus architectures. The ALS series offers a balance of speed and power consumption suitable for general-purpose digital logic. Verify input compatibility with existing TTL drivers and ensure the SOIC-20 footprint fits the target PCB layout constraints.

Flip Flops Part Context

This part belongs to the SN74ALS576B family, which includes variants like the SN74ALS576BN (PDIP) and SN74ALS576BNE4. The BNSR suffix specifically denotes the small-outline integrated circuit package with reel or cut-tape packaging options, distinguishing it from through-hole or alternative lead-free versions.

Flip Flops Replacement Considerations

The SN74ALS576BNG4 is a confirmed substitute offering identical functionality with updated manufacturing revisions. Other family members such as the SN74ALS576BN provide the same electrical characteristics but utilize a different physical package format.
