SN74AS841ADW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AS841ADW 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 from 0°C to 70°C. The device features noninverting data inputs and buffered control inputs to reduce DC loading effects. Key electrical parameters include a high-level output current of -24mA and a low-level output current of 48mA. Propagation delays from D to Q range from 1ns to 10.5ns, while LE to Q delays range from 2ns to 12ns under standard load conditions.

Buffers, Drivers, Receivers, Transceivers Feature Summary

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

Buffers, Drivers, Receivers, Transceivers Applications

• Implementing buffer registers in digital systems
• Configuring I/O ports for data handling
• Serving as bidirectional bus drivers
• Functioning as working registers in memory architectures

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DW' corresponds to the plastic small-outline package configuration required for your design. Confirm that the component meets RoHS compliance standards if environmental regulations apply to your manufacturing process. Ensure the selected variant matches the exact logic family specifications for signal integrity compatibility.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing wide address or data paths requiring additional bus-driving latches. The AS series offers higher drive currents compared to ALS variants, making it suitable for low-impedance loads. Verify that the 24-pin SOIC package dimensions fit the available PCB real estate and thermal management requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AS841A family of 10-bit bus-interface D-type latches. It shares functional similarities with the SN74ALS841 but provides enhanced drive strength. The device is characterized for commercial temperature ranges and is intended for general-purpose digital logic applications involving bus interfacing.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74ALS841DW is a similar alternative within the same product family offering comparable functionality with different drive characteristics. Verify pinout compatibility and electrical parameter alignment before substitution.
