SN74AS841ANT

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AS841ANT 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. 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.

• Serving as bidirectional bus drivers
• Functioning as working registers in memory architectures

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized distributors or TI direct channels. Confirm RoHS compliance status and check for specific package markings corresponding to the NT designation. Ensure the supplier provides valid traceability documentation. Validate that the received parts match the specified 24-pin DIP package dimensions and pinout configuration before integration into production assemblies.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 10-bit latching with high-drive capability for bus structures. Compare propagation delay specifications against system timing requirements to ensure compatibility with clock speeds. Evaluate the 3-state output impedance characteristics against the target bus load capacitance. Consider the buffered input structure if minimizing source loading is critical for the design architecture.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Texas Instruments 74AS series of logic components, known for advanced Schottky technology providing higher speed performance compared to standard TTL families. The SN74AS841A variant specifically addresses applications needing fast bus-interface latching with robust drive strength, fitting within the broader category of 10-bit bus-interface D-type latches with 3-state outputs.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74ALS841NT serves as a functional substitute within the same family, offering similar latch functionality but with different electrical drive characteristics and slightly slower switching speeds. Verify pin compatibility and ensure the alternative meets the specific current drive requirements of the application bus.
