SN74HCT573ANSR

Latches Overview

The SN74HCT573ANSR is an octal transparent D-type latch manufactured by Texas Instruments, belonging to the 74HCT logic series. It features eight D-type latches with 3-state outputs in a 20-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 52 ns at 4.5 V and 47 ns at 5.5 V. Static current consumption is specified at 8 uA. The low-level output current capability is 32 mA, while the high-level output current is -6 mA. The component supports surface mount installation and functions within an operating temperature range of -40°C to +85°C.

Latches Feature Summary

• Provides octal data storage via eight independent D-type latches
• Features 3-state outputs for effective bus line driving
• Compatible with CMOS logic using TTL-compatible voltages

Latches Applications

• Registering fast-moving data in digital systems
• Driving bus lines requiring 3-state control
• Parallel-to-serial data conversion circuits

Latches Procurement Notes

Verify the specific suffix ANSR against official datasheets to confirm the SOIC-20 package and tape-and-reel packaging configuration. Confirm RoHS compliance status through manufacturer documentation. Ensure the part number matches the exact HCT series specifications required for your circuit design before procurement.

Latches Selection Notes

Select this component when interfacing between CMOS and TTL logic families is required. The HCT series ensures compatibility with standard 5V logic levels. Consider the 3-state output feature if bus sharing is necessary. Verify that the SOIC-20 package fits the PCB layout constraints and thermal requirements of the application.

Latches Part Context

This component is part of the SN74HCT573 family of octal latches. It shares functional similarities with other 74-series logic devices but is optimized for high-speed CMOS technology with TTL-compatible inputs. The SN74HCT573ANSR variant specifically denotes the surface-mount reel packaging option.

Latches Replacement Considerations

Check for direct pin-compatible alternatives such as the SN74HCT573DR or SN74HCT573N depending on package preference. Verify that substitute parts maintain the same HCT logic family characteristics and 3-state output functionality.
