SN74LVC373ADWG4

Latches Overview

The SN74LVC373ADWG4 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 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 SOIC 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 prevents back-drive current during partial power-down
• High ESD protection ratings 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 lead-free and RoHS-compliant manufacturing standards as defined by Texas Instruments. Confirm that the SOIC-20 package dimensions match the design footprint requirements. Ensure the operating temperature range of -40°C to 125°C aligns with the environmental conditions of the target application. Cross-reference the datasheet revision history for any recent parameter updates or packaging changes.

Latches Selection Notes

Select this component when an octal latch with three-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 6.8 ns propagation delay for timing constraints and the 24 mA drive strength for load requirements. Verify that the 20-pin SOIC package fits the available PCB space and assembly capabilities.

Latches Part Context

This part belongs to the SNx4LVC373A family of octal transparent D-type latches. The 'G4' suffix indicates compliance with lead-free and RoHS directives. It shares functional characteristics with other variants in the series but differs in packaging and environmental specifications. The device is designed for high-speed digital logic applications requiring data retention and bus driving capabilities.

Latches Replacement Considerations

SN74LVC373ADW is the non-RoHS equivalent in the same SOIC-20 package. SN74LVC373ADWR offers the same functionality in a tape-and-reel format. SN74LVC373APW is available in a TSSOP-20 package for different footprint requirements.
