SN74LVC841ADWR

Latches Overview

The SN74LVC841ADWR 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 noninverting data inputs and true data at its outputs, with a buffered output-enable (OE) input to control the high-impedance state. It is designed for driving highly capacitive or low-impedance loads, offering a maximum propagation delay of 6.7 ns at 3.3 V.

Latches Feature Summary

• Supports partial-power-down mode operation via Ioff circuitry to prevent damaging current backflow when powered down.
• Enables mixed-mode signal operation allowing 5-V input/output voltage compatibility with 3.3-V VCC systems.
• Provides high-impedance state capability to drive bus lines without requiring interface or pullup components.

Latches Applications

• Implementing buffer registers in digital circuits
• Designing I/O ports for system interfaces
• Constructing bidirectional bus drivers
• Utilizing as working registers in data processing

Latches Procurement Notes

Verify the specific package type and reel quantity against the ordering information table. Confirm the operating temperature range matches the application requirements. Ensure the datasheet revision date aligns with design specifications. Check RoHS compliance status if required by manufacturing standards. Validate pinout configurations for the SOIC-24 package before finalizing procurement.

Latches Selection Notes

Select this component for applications requiring 10-bit latching with 3-state outputs in low-voltage environments. Consider the 5.5 V input tolerance for interfacing with higher voltage logic levels. Evaluate the propagation delay characteristics for timing-sensitive designs. Assess the power consumption and static current parameters for energy-efficient systems. Verify the package availability for surface-mount assembly processes.

Latches Part Context

This part belongs to the SN74LVC841A series of 10-bit bus-interface D-type latches. It is part of the broader LVC logic family designed for low-voltage CMOS applications. The device shares functional similarities with other bus-interface latches but offers specific 10-bit width and 3-state output capabilities tailored for bus-driven systems.

Latches Replacement Considerations

Check for SN74LVC841ADW as a tube-packaged alternative. Verify SN74LVC841APWR for TSSOP package compatibility. Confirm SN74LVC841ADBR for SSOP package options. Ensure electrical parameters match for direct substitution.

Latches FAQ

How does the device handle partial-power-down scenarios?

The device includes Ioff circuitry that disables the outputs to prevent damaging current backflow through the device when it is powered down.

Can this latch interface with 5-V devices while operating at 3.3 V?

Yes, the inputs accept voltages up to 5.5 V, allowing the device to support mixed-mode signal operation on all ports with 5-V input/output voltage while using a 3.3-V VCC.
