SN74ALS540-1N

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALS540-1N is an octal buffer and line driver from the Texas Instruments ALS logic family. It features eight inverting outputs with three-state capability, housed in a 20-pin DIP package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 12 ns, high-level output current of -15 mA, and low-level output current of 24 mA. It supports a maximum operating temperature of +70°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides eight-channel signal buffering and driving with inverting polarity.
• Features three-state outputs for effective bus line management.
• Utilizes advanced low-power Schottky (ALS) technology for improved performance.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix '-1N' against official manufacturer documentation to confirm exact pinout and mechanical dimensions. Ensure compatibility with existing PCB footprints before procurement. Confirm that the component meets required environmental standards for the intended application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal buffering with three-state control. Consider the ALS series characteristics for applications needing lower power consumption than standard TTL while maintaining faster switching speeds. Verify that the 20-pin DIP package fits the assembly constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74ALS540 series of octal buffers. It is distinct from other variants like the DW or NSR packages which offer surface-mount options. The 'N' suffix typically denotes the through-hole DIP packaging style used in legacy or prototyping designs.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements may include SN74ALS540DW or SN74LS540NSR, provided package differences are accommodated. Verify functional equivalence regarding propagation delay and drive strength before substitution.
