74AC241SJ

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74AC241SJ is an octal buffer and line driver featuring non-inverting 3-STATE outputs. It operates within a supply voltage range of 2.0V to 6.0V and supports an operating temperature from -40°C to +85°C. The device provides source/sink currents of 24mA and utilizes a 20-Lead Small Outline Package (SOP) with EIAJ TYPE II dimensions. Propagation delays are specified at 9ns for 3.3V operation and 7ns for 5V operation.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Non-inverting 3-STATE outputs designed to drive bus lines or buffer memory address registers
• Outputs capable of sourcing and sinking 24mA current
• Reduced ICC and IOZ power consumption by 50% compared to standard AC logic

Buffers, Drivers, Receivers, Transceivers Applications

• Memory address drivers
• Clock drivers
• Bus-oriented transmitters or receivers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant, as the SJ suffix denotes a 20-Lead SOP (EIAJ TYPE II). Confirm RoHS compliance status directly with the manufacturer, as historical documentation indicates variations in lead-free certification across different production runs and distributors. Ensure the ordering number matches the required pinout and physical dimensions for your PCB layout.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with high-drive capability and low quiescent current is required. The AC series offers wider voltage tolerance than ACT variants. Verify that the 24mA output drive meets the load requirements of the destination circuitry. Consider the 3-STATE functionality for bus sharing applications where multiple devices connect to the same data lines.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AC family of high-speed CMOS logic devices originally developed by Fairchild Semiconductor. The 74AC241 specifically provides eight independent buffers with three-state control. It is functionally similar to the 74ACT241 but differs in input threshold voltages and supply voltage ranges. The SJ package variant is distinct from the SC (SOIC) and MTC (TSSOP) options.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74ACT241SJ is a compatible alternative with TTL-compatible inputs. Other octal buffers like the 74AC244 may be considered if inverted outputs are acceptable. Verify pin compatibility and electrical characteristics before substitution.
