SN74F573DWR

Overview

The SN74F573DWR is an octal transparent D-type latch manufactured by Texas Instruments, belonging to the SN74F logic series. It features eight non-inverting D-type latches with three-state outputs housed in a 20-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a propagation delay of 7 ns at 5 V. It provides a low-level output current of 32 mA and a high-level output current of -3 mA. The component functions reliably across an operating temperature range from 0°C to +70°C.

Feature Summary

• Octal transparent D-type latch configuration with eight independent channels
• Three-state outputs for effective bus-driven operations
• Non-inverting logic polarity for direct data path transmission

Applications

• Parallel-to-serial data conversion circuits
• Register file implementations in digital systems
• Bus-oriented memory storage applications

Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel packaging format intended for automated assembly processes. Ensure the selected variant matches the required thermal management specifications for the target operating environment. Confirm RoHS compliance status aligns with regional regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when high-speed switching capabilities are required within standard 5 V logic families. The SN74F series offers faster performance compared to LS or HC counterparts while maintaining compatible pinouts. Evaluate the trade-off between speed and power consumption against alternative logic families suitable for the specific application constraints.

Part Context

This part belongs to the widely adopted SN74xx logic family, representing a standard solution for general-purpose digital logic applications. The SN74F573 variant specifically targets designs requiring moderate speed and robust drive capability. It serves as a foundational building block for complex digital architectures involving data buffering and temporary storage.

Replacement Considerations

SN74ACT573DWR: Offers improved switching speeds and higher drive currents while maintaining electrical compatibility within the same 5 V logic family.
