SN74LVC373APWE4

Latches Overview

The SN74LVC373APWE4 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 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
• Latch-up performance exceeds 250 mA per JESD 17

Latches Applications

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

Latches Procurement Notes

Verify the specific ordering suffix 'E4' against the manufacturer's current documentation to confirm lead-free status and RoHS compliance details. Ensure the TSSOP-20 package dimensions match the design constraints. Confirm that the -40°C to 125°C operating temperature range aligns with the target application environment requirements.

Latches Selection Notes

Select this component when an octal latch with high drive capability and 5.5 V tolerant inputs is required. The device is suitable for bus-interface applications where data retention is necessary. Consider the 24 mA output drive strength and low static power consumption characteristics for efficient system design.

Latches Part Context

This part belongs to the SNx4LVC373A family of octal transparent D-type latches with three-state outputs. The 'E4' suffix typically indicates environmental compliance modifications, such as lead-free packaging, while maintaining the core electrical specifications of the standard SN74LVC373A series.
