SN74LVC841ADBR

Latches Overview

The SN74LVC841ADBR 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 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 SSOP (DB) package.

Latches Feature Summary

• Features 3-state outputs controlled by an output-enable input for high-impedance state management.
• Supports mixed-mode signal operation allowing 5-V input/output voltage compatibility with 3.3-V VCC.
• Includes Ioff circuitry to prevent damaging current backflow during partial-power-down applications.

Latches Applications

• Implementing buffer registers
• Configuring I/O ports
• Bidirectional bus drivers
• Working registers

Latches Procurement Notes

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

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 5.5 V tolerant inputs if interfacing with higher voltage logic levels while maintaining a lower core supply voltage.

Latches Part Context

This part belongs to the LVC/LCX/Z logic family from Texas Instruments. It is a production-grade device designed for general-purpose digital logic applications. The datasheet indicates it is available in multiple package options including SOIC, TSSOP, and TVSOP variants alongside the SSOP version.

Latches Replacement Considerations

Direct substitutes include SN74LVC841ADW (SOIC), SN74LVC841APW (TSSOP), and SN74LVC841ADGVR (TVSOP). These parts share identical electrical characteristics and pinouts but differ in physical package dimensions.
