SNJ54ABT240W

Buffers, Drivers, Receivers, Transceivers Overview

The SNJ54ABT240W is an octal buffer and line driver featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating free-air temperature from -55°C to 125°C. The device utilizes ABT logic technology and provides high-drive outputs with a maximum high-level output current of -32 mA and a low-level output current of 64 mA. It incorporates Ioff circuitry to support partial-power-down mode operation, preventing damaging backflow currents when the device is powered down.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features high-drive outputs capable of sourcing -32 mA and sinking 64 mA for robust signal transmission.
• Includes Ioff circuitry that disables outputs during partial-power-down to prevent damaging backflow currents.
• Provides symmetrical active-low output-enable inputs for flexible bus-oriented receiver and transmitter configurations.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'W' corresponds to the CFP package type and military-grade temperature range (-55°C to 125°C). Confirm RoHS status and lead finish details in the latest Package Option Addendum, as manufacturing parameters may evolve. Ensure compatibility with MIL-PRF-38535 requirements if applicable to the procurement specification.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring wide industrial or military temperature ranges and high drive strength. The SNJ54ABT240W offers complementary OE and OE inputs alongside symmetrical active-low options, providing design flexibility compared to devices with fixed enable logic. Consider the CFP package constraints for board layout and thermal management.
