SN74LVC373ADBR

Latches Overview

The SN74LVC373ADBR is an octal transparent D-type latch with three-state outputs manufactured by Texas Instruments. It operates from a supply voltage of 1.65 V to 3.6 V and accepts input voltages up to 5.5 V, supporting mixed-mode signal operation. The device features a maximum propagation delay of 6.8 ns at 3.3 V and provides high drive current capability of ±24 mA. It includes Ioff support for partial-power-down mode and back-drive protection. The component is housed in a 20-pin SSOP package and is rated for an operating temperature range of -40°C to 125°C.

Latches Feature Summary

• Operates within a wide voltage range of 1.65 V to 3.6 V
• Inputs accept voltages up to 5.5 V for mixed-mode compatibility
• Supports live-insertion and partial-power-down modes via Ioff circuitry
• Provides high-drive outputs capable of driving bus lines without interface components

Latches Applications

• Network switches
• TV set-top boxes
• Motor drives
• PCs and notebooks

Latches Procurement Notes

Verify the specific ordering suffix 'DBR' corresponds to the SSOP-20 package and tape-and-reel carrier configuration. Confirm that the RoHS compliance status and lead finish (NIPDAU) match the project requirements. Ensure the moisture sensitivity level (Level-1) and peak reflow temperature limits are compatible with the assembly process. Check for any recent product change notices affecting pinout or electrical characteristics.

Latches Selection Notes

Select this component when an octal latch with three-state outputs is required for low-voltage logic systems. The 5.5 V tolerant inputs make it suitable for translating signals between 3.3 V and 5 V domains. The high drive current supports direct connection to buses or LEDs. Consider the SSOP package dimensions and thermal resistance if space or heat dissipation is constrained.

Latches Part Context

This part belongs to the SNx4LVC373A family of octal transparent D-type latches. It shares functional similarities with other LVC series devices but is optimized for 1.65 V to 3.6 V operation. The 'ADBR' suffix indicates the specific manufacturer prefix, package type (SSOP), and reel quantity. It is distinct from flip-flop variants like the SN74LVC374 which use clocked triggering rather than latch-enable transparency.

Latches Replacement Considerations

SN74LVC373ADWR offers identical functionality in a SOIC-20 package with tape-and-reel packaging. SN74LVC373APW provides the same electrical performance in a TSSOP-20 package.
