SN74F541NSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74F541NSR is an octal buffer and line driver manufactured by Texas Instruments, housed in a 20-pin Small Outline Package (SOP). It features three-state outputs designed for driving bus lines or buffering memory address registers. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating free-air temperature range from 0°C to 70°C. Key electrical characteristics include a low-level output current capability of up to 64 mA and a high-level output current of -15 mA at VCC = 5 V.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features inputs and outputs on opposite sides of the package to facilitate printed-circuit-board layout.
• Includes two active-low output enable inputs that place all eight outputs in a high-impedance state when asserted high.
• Provides three-state outputs suitable for direct connection to bus lines.

• Driving bus lines
• Buffering memory address registers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'NSR' corresponds to the SOP package with tape-and-reel packaging containing 2000 units per reel. Confirm the RoHS status and lead finish details match project requirements. Ensure the operating temperature range of 0°C to 70°C aligns with the environmental conditions of the target application before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state control is required for bus interfacing. Consider the pinout arrangement where inputs are on one side and outputs on the other for PCB layout optimization. Verify that the F-series logic family speed and drive current specifications meet the system's timing and load requirements compared to alternative logic families.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN54/74F541 family of octal buffers/drivers with three-state outputs. The SN74 variant is characterized for commercial temperature ranges, while the SN54 variant supports military specifications. The device is part of the standard F-series logic family, known for its specific switching characteristics and power consumption profiles relative to other logic types.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include SN74F541DWR and SN74F541NSR.A, which share identical functionality and pinouts. Other variants such as SN74F541N offer the same logical function but in a different package type. Ensure any replacement maintains the 20-pin configuration and three-state output capabilities.
