SN74ACT241NS

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ACT241NS is an octal buffer and line driver manufactured by Texas Instruments, belonging to the SN74ACT logic family. It features non-inverting outputs with three-state capability, allowing multiple drivers to share a bus without contention. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL-compatible inputs with CMOS outputs. It is housed in a 20-pin Small Outline (SO) package and is rated for operation over an extended temperature range from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides eight non-inverting buffer channels with independent output enable controls for flexible bus management.
• Features three-state outputs that isolate disconnected lines when disabled, preventing signal interference on shared buses.
• Ensures compatibility with standard logic families through TTL-level input thresholds and CMOS-level output drive characteristics.

Buffers, Drivers, Receivers, Transceivers Applications

• Clock distribution networks requiring high fan-out and controlled signal timing.
• Memory address and data bus drivers in computer systems.
• Control signal buffering for peripheral interface circuits.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'NS' against the manufacturer's current naming convention, as it may denote a specific tape-and-reel or tube variant. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the ordering part number matches the required package type and temperature grade for your design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require driving multiple loads from a single source while maintaining signal integrity. The ACT series offers faster switching speeds compared to older LS or HC families. Consider the three-state feature if the circuit involves bidirectional data transfer or multiplexed bus architectures.

Buffers, Drivers, Receivers, Transceivers Part Context

This component is part of the broader SN74ACT series, which bridges the performance gap between legacy TTL and modern CMOS technologies. It shares functional similarities with other octal buffers like the SN74ACT244 but differs in pinout configuration and control logic. The series is widely used in industrial and consumer electronics for reliable digital signal transmission.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-to-pin replacements include the SN74ACT244N and SN74ACT245N, provided the directionality and enable logic match the application requirements. Verify that substitute parts maintain the same voltage levels and package dimensions to ensure mechanical and electrical compatibility.
