SN74ACT241DBR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ACT241DBR is an octal buffer and line driver from the Texas Instruments ACT logic family, housed in a 20-pin SSOP package. It operates within a supply voltage range of 4.5V to 5.5V. The device features two independent 4-bit sections with separate complementary output-enable inputs (1OE and 2OE). It provides non-inverting data transfer from A inputs to Y outputs when enabled, entering a high-impedance state when disabled. Key electrical characteristics include a maximum propagation delay of 8.5ns at 5V, TTL-compatible inputs, and output drive capabilities of ±24mA.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal buffering architecture organized into two independent 4-bit sections for flexible bus management
• Three-state outputs controlled by dedicated complementary enable pins to prevent bus contention
• TTL-compatible input thresholds allowing direct interfacing with standard logic families
• High-drive capability supporting loads up to ±24mA for reliable signal transmission

Buffers, Drivers, Receivers, Transceivers Applications

• Memory address drivers in computer systems
• Clock distribution networks
• Bus-oriented receivers and transmitters

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DBR' corresponds to the SSOP-20 package and tape-and-reel carrier configuration. Confirm RoHS compliance status and lead finish details against the latest manufacturer packaging addendum. Ensure the procurement source provides valid traceability documentation for this catalog part number.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal buffering with independent control over two 4-bit groups. The ACT series offers improved speed and density compared to legacy counterparts. Verify that the required operating temperature range of -40°C to +85°C aligns with the system environment and that the 4.5V to 5.5V supply voltage matches the design power rails.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SNx4ACT241 family of octal buffers/drivers. While other variants exist in different packages such as SOIC (DW), TSSOP (PW), or PDIP (N), the DBR suffix specifically denotes the shrink small-outline package (SSOP) with reel packaging. It shares functional compatibility with the broader SN74ACT241 product line while offering distinct physical footprint dimensions.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible alternatives within the same package include SN74ACT241NSR (SOP) and SN74ACT241PWR (TSSOP). Cross-package replacements like SN74ACT240DWR are functionally similar but inverted. Verify thermal resistance and package dimensions before substituting.
