SNJ54AC245W

Buffers, Drivers, Receivers, Transceivers Overview

The SNJ54AC245W is an octal bus transceiver with three-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports a maximum propagation delay of 7 ns at 5 V. The device features bidirectional data transmission between two buses controlled by a direction input, with an output-enable input for isolation. It utilizes ceramic flatpack (CFP) packaging with 20 pins and is rated for operation in temperatures from -55°C to 125°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'W' corresponds to the CFP package variant when sourcing. Confirm that the military-grade SNJ prefix meets all environmental and reliability standards required for the intended deployment environment. Ensure compatibility with existing system power supplies within the specified 2 V to 6 V operational range.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust bidirectional data transfer across multiple lines. Consider its extended temperature range and radiation tolerance if used in harsh environments. Evaluate the trade-off between its slower edge rates and reduced signal integrity issues compared to faster alternatives.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SNx4AC245 family of octal bus transceivers. It shares functional characteristics with other AC series devices but is distinguished by its military-grade qualification and ceramic packaging. It serves as a bridge for connecting different logic domains or extending bus distances in complex digital systems.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle bus isolation?

The output-enable (OE) input can be used to disable the device, effectively isolating the A and B buses from each other.

What determines the direction of data flow?

Data transmission direction is determined by the logic level at the direction-control (DIR) input, allowing transfer from A to B or B to A.
