SN74LS541NSRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LS541NSRG4 is an octal buffer and line driver from the Texas Instruments LS logic series. It features eight non-inverting channels with three-state outputs, housed in a 20-pin PDIP package. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical characteristics include a low-level output current of 48 mA and a high-level output current of -15 mA. The component supports surface mount or through-hole installation depending on the specific variant suffix, with a standard operating temperature range extending up to +70°C for commercial applications.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix 'G4' confirms lead-free status and RoHS compliance as per manufacturer specifications. Ensure the package type matches the required PCB footprint, as variations exist between DIP and SOIC formats within the same logical family. Confirm the specific temperature grade aligns with the intended operational environment before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-current drive capability is required for long bus lines or multiple fan-out scenarios. The LS series offers a balance of speed and power consumption suitable for general-purpose TTL-compatible designs. Consider alternative variants if extended temperature ranges or lower supply voltages are necessary for the target application.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the widely adopted 74LS541 octal buffer family, serving as a standard interface solution in legacy and modern digital electronics. It facilitates bidirectional data transfer and signal conditioning between microprocessors and peripheral devices. The G4 suffix indicates environmental compliance, distinguishing it from older non-compliant manufacturing runs while maintaining identical functional pinouts.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LS541N serves as a direct functional equivalent without the G4 suffix. SN74ALS541 provides faster switching speeds but requires careful attention to power dissipation differences.
