SN74LVC841ADW

Latches Overview

The SN74LVC841ADW is a 10-bit bus-interface D-type latch with 3-state outputs manufactured by Texas Instruments. It operates from a supply voltage range of 1.65 V to 3.6 V and features inputs that accept voltages up to 5.5 V, supporting mixed-mode signal operation on all ports. The device provides a maximum propagation delay (tpd) of 6.7 ns at 3.3 V and includes Ioff circuitry to support partial-power-down mode. It is housed in a 24-pin SOIC (DW) package.

Latches Feature Summary

• Supports mixed-mode signal operation allowing 5-V input/output voltage compatibility with 3.3-V VCC
• Includes Ioff circuitry to disable outputs and prevent damaging current backflow during partial-power-down applications
• Features buffered output-enable (OE) input to place ten outputs in either normal logic states or high-impedance state

Latches Applications

• Implementing buffer registers
• Configuring I/O ports
• Designing bidirectional bus drivers
• Utilizing as working registers

Latches Procurement Notes

Verify the specific ordering suffix 'DW' corresponds to the SOIC package type when sourcing components. Confirm RoHS compliance status and lead finish details against the manufacturer's latest packaging information addendum. Ensure the operating temperature range meets system requirements for -40°C to 85°C environments.

Latches Selection Notes

Select this component for designs requiring 10-bit data storage with tri-state control. It is suitable for driving highly capacitive or low-impedance loads. Consider its ability to interface between 3.3-V and 5-V devices if mixed-voltage systems are utilized. Verify that the 1.65-V to 3.6-V supply range aligns with the target power architecture.

Latches Part Context

This device belongs to the LVC/LCX/Z logic family from Texas Instruments. It is part of the SN74LVC841A series, which consists of 10-bit bus-interface D-type latches with 3-state outputs. The DW suffix indicates the standard SOIC plastic small-outline package variant within this product line.

Latches Replacement Considerations

Check for direct pin-compatible alternatives within the same LVC family. Verify functional equivalence regarding the 10-bit width and 3-state output configuration before substitution.
