SN74LV573ADBR

Latches Overview

The SN74LV573ADBR is an octal transparent D-type latch manufactured by Texas Instruments, featuring tri-state outputs. It operates within a supply voltage range of 2 V to 5.5 V and supports surface-mount installation in a 20-SSOP package. The device exhibits propagation delays of 18.7 ns at 2.5 V, 14.5 ns at 3.3 V, and 8.8 ns at 5 V. Static current consumption is specified at 20 uA. Output drive capabilities include a low-level output current of 32 mA and a high-level output current of -16 mA. It functions reliably across an operating temperature range from -40 C to +85 C.

Latches Feature Summary

• Provides eight independent transparent D-type latches with tri-state control for bus-oriented memory mapping and driving.

Latches Applications

• Bus-oriented architectures requiring data storage and isolation
• Memory mapping applications involving address and data lines
• Driving capacitive or resistive loads in digital systems

Latches Procurement Notes

Verify the specific package variant matches the design requirement, as the SN74LV573 series includes SSOP, SOIC, TSSOP, TVSOP, and VQFN options. Confirm that the logic family LV aligns with the system voltage levels, distinguishing it from HC or LVT variants. Ensure the manufacturer designation corresponds to Texas Instruments to guarantee parameter accuracy and compliance with the documented electrical specifications.

Latches Selection Notes

Select this component when an octal latch with tri-state functionality is required for low-voltage operation between 2 V and 5.5 V. The LV series offers faster switching speeds compared to standard HC logic while maintaining compatibility with 5 V systems. Consider the 20-SSOP package for space-constrained surface-mount designs. Verify that the 32 mA low-level sink current meets the load requirements of the connected circuitry.

Latches Part Context

This part belongs to the SN74LV573A series of octal transparent D-type latches with tri-state outputs. The 'A' suffix typically denotes improved specifications or revisions within the family. The 'D' indicates the SSOP-20 package, while 'B' signifies tape-and-reel packaging. This series is designed for low-voltage CMOS applications requiring high-speed performance and wide supply voltage flexibility.
