SN74ABT573N

Latches Overview

The SN74ABT573N is an octal transparent D-type latch manufactured by Texas Instruments within the ABT logic series. It features eight D-type latches with three-state outputs, housed in a 20-pin PDIP package for through-hole mounting. The device operates on a single power supply ranging from 4.5 V to 5.5 V and supports a wide operating temperature range from -40°C to +85°C. Key electrical characteristics include a propagation delay of 5.7 ns, low-level output current of 32 mA, and high-level output current of -32 mA.

Latches Feature Summary

• Provides tri-state control for data bus isolation and buffering applications
• Ensures data integrity via transparent latch operation synchronized with the enable signal
• Supports standard TTL input voltage levels for compatibility with legacy systems

Latches Applications

• Data bus buffering and isolation in microprocessor-based systems
• Registering incoming data streams for synchronous processing
• Interface circuits requiring high-speed data storage and retrieval

Latches Procurement Notes

Verify the specific ordering suffix to confirm the package type and lead-free status, as variations exist within the product line. Confirm RoHS compliance requirements against the latest manufacturer documentation before procurement. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment.

Latches Selection Notes

Select this component when designing systems requiring high-speed data latching with tri-state output capabilities. The ABT series offers superior performance compared to standard 74LS logic while maintaining pin compatibility. Consider the 20-pin DIP package for prototyping or applications necessitating through-hole assembly techniques.
