SN74LVC841APW

Latches Overview

The SN74LVC841APW 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 TSSOP 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
• Provides high-impedance state capability to drive bus lines without interface or pullup components

Latches Applications

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

Latches Procurement Notes

Verify the specific ordering suffix 'PW' corresponds to the TSSOP package type when sourcing this component. Confirm the manufacturer is Texas Instruments to ensure compliance with the specified electrical characteristics and operating temperature range of -40°C to 85°C. Cross-reference the datasheet revision SCAS307J for accurate timing requirements.

Latches Selection Notes

Select this component for designs requiring 10-bit data storage with tri-state output control. It is suitable for driving highly capacitive or low-impedance loads within the 1.65-V to 3.6-V supply range. Ensure system interfaces are compatible with the 5.5-V input voltage tolerance if interfacing with higher voltage logic levels.

Latches Part Context

This part belongs to the SN74LVC841A family of 10-bit bus-interface D-type latches. The 'PW' suffix specifically denotes the plastic small-outline package variant. It is designed for low-voltage CMOS applications requiring high-speed data latching and bus isolation capabilities.
