SN74LVC373APWG4

Latches Overview

The SN74LVC373APWG4 is an octal transparent D-type latch with 3-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 includes Ioff circuitry for partial-power-down mode. It provides high drive capability with output currents up to 24 mA and offers ESD protection exceeding 2000 V via the human-body model. The component is housed in a 20-pin TSSOP package.

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
• Ioff feature supports live-insertion and back-drive protection
• High ESD protection performance across multiple testing models

Latches Applications

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

Latches Procurement Notes

Verify the specific ordering suffix 'G4' corresponds to the desired RoHS-compliant variant and lead finish. Confirm the package type matches the required PCB footprint, as this part number specifies the TSSOP-20 configuration. Ensure the operating temperature range meets system requirements, as industrial variants may differ. Cross-reference the datasheet revision date to confirm parameter validity against current design specifications.

Latches Selection Notes

Select this component when an octal latch with 3-state outputs is required for bus interface applications. It is suitable for designs needing voltage translation between 3.3-V and 5-V systems due to its 5.5-V tolerant inputs. Consider the 24-mA drive capability for driving multiple loads or high-speed buses. Verify that the TSSOP-20 package dimensions fit the available board space and thermal constraints.

Latches Part Context

This device belongs to the SNx4LVC373A family of octal transparent D-type latches. It shares functional similarities with other LVC series components but is distinguished by its specific pinout and package options. The 'PW' suffix indicates the TSSOP package, while 'G4' denotes environmental compliance. It serves as a standard solution for data retention and buffering in low-voltage digital logic circuits.

Latches Replacement Considerations

SN74LVC373APW is the non-RoHS equivalent without the G4 suffix. SN74LVC373ADW offers the same functionality in a SOIC-20 package. SN74LVC373ADBRG4 provides the same electrical characteristics in an SSOP-20 package. All listed alternatives maintain the octal latch architecture and 3-state output capabilities.
