SN74ALS841DWRG4

Overview

The SN74ALS841DWRG4 is a 10-bit bus-interface D-type latch with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range of 0°C to 70°C. The device features noninverting data inputs and buffered control inputs to reduce DC loading effects. Propagation delay from the data input (D) to the output (Q) ranges from 2ns to 13ns, while the latch enable (LE) to output delay spans 7ns to 26ns under standard load conditions.

Feature Summary

• Features 3-state buffer-type outputs designed for driving highly capacitive or low-impedance loads directly on bus lines without interface components.
• Includes buffered control inputs to minimize DC loading effects during operation.
• Provides a power-up high-impedance state to ensure safe initialization in bus systems.

Applications

• Implementing buffer registers in digital circuits
• Configuring I/O ports for data handling
• Serving as bidirectional bus drivers
• Functioning as working registers in wider address/data paths

Procurement Notes

Verify that the ordering suffix 'G4' confirms compliance with RoHS 3 standards and specifies lead-free packaging. Confirm the package type corresponds to the plastic small-outline (DW) variant. Ensure the component status aligns with current production availability requirements for your specific design lifecycle.

Selection Notes

Select this component when designing systems requiring 10-bit latching capability with 3-state bus interfacing. It is suitable for applications needing buffered control inputs to reduce loading. Consider the ALS series performance characteristics regarding speed and power consumption relative to other logic families available from the manufacturer.

Part Context

This part belongs to the SN74ALS841 family of 10-bit bus-interface D-type latches. It shares functional similarities with the SN74AS841A and SN74ALS842, differing primarily in drive strength and specific electrical characteristics. The DW package option provides a surface-mount solution compatible with standard PCB manufacturing processes.
