SN74ALS576BDW

Flip Flops Overview

The SN74ALS576BDW is an octal D-type edge-triggered flip-flop from the Texas Instruments ALS logic series. It features eight independent circuits with three-state outputs in a 20-pin SOIC package. The device operates on a single 4.5 V to 5.5 V supply and supports through-hole or surface-mount installation. Key electrical parameters include a maximum propagation delay of 14 ns at 5 V with 50 pF load, a clock frequency of 30 MHz, and output currents of -2.6 mA (high) and 24 mA (low). It functions within a temperature range of 0°C to +70°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type edge-triggered flip-flops for parallel data handling.
• Three-state outputs enable direct system bus interconnection without additional interface hardware.
• ALS technology ensures high-speed operation with low power consumption compared to standard TTL.
• Inverting polarity provides complementary output signals relative to the input data state.

Flip Flops Applications

• Registering parallel data in microprocessor-based systems
• Buffering and latching operations on system buses
• Clock-controlled data storage in digital logic circuits
• Interface control between high-speed logic components

Flip Flops Procurement Notes

Verify the specific suffix 'BDW' corresponds to the 20-SOIC surface-mount package variant rather than the PDIP version. Confirm RoHS compliance status as manufacturing revisions may affect environmental certifications. Ensure the ordering part number matches the required pinout and electrical specifications for the target application design.

Flip Flops Selection Notes

Select this component when an octal latch with three-state capability is required for bus-oriented designs. The ALS series offers a balance of speed and power suitable for general-purpose logic applications. Consider the SOIC package format for automated surface-mount assembly processes. Verify that the 30 MHz clock limit meets the timing requirements of the system architecture.

Flip Flops Part Context

This part belongs to the SN74ALS576B family of octal D-type flip-flops. It is functionally similar to the SN74ALS574 but includes inverters at the outputs. The 'B' suffix typically denotes a specific revision or packaging variant within the ALS product line. It serves as a core building block for sequential logic circuits requiring parallel data retention.

Flip Flops Replacement Considerations

• SN74ALS576BN (PDIP-20 package)
• SN74ALS576BDWE4 (Lead-free SOIC-20 package)
