SNJ54AC245J

Buffers, Drivers, Receivers, Transceivers Overview

The SNJ54AC245J is an octal bus transceiver with three-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 6V and supports an operating temperature from -55°C to 125°C. The device features a maximum propagation delay of 7ns at 5V and accepts input voltages up to 6V. It utilizes a 20-pin Ceramic Dual In-Line Package (CDIP) for military-grade applications.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'J' corresponds to the CDIP package variant. Confirm that the military grade qualification aligns with project requirements. Check current availability status as military components may have restricted supply chains. Ensure ESD handling protocols are followed during installation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring wide voltage operation and high-temperature stability. The AC series offers balanced output drive suitable for minimizing ringing. Verify that the 20-pin CDIP footprint matches the PCB layout constraints. Consider the slow edge rates for applications sensitive to overshoot and undershoot.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SNx4AC245 family of octal bus transceivers. It shares functional similarities with commercial variants like the SN74AC245 but is qualified for extended temperature ranges. The device serves as a bidirectional interface for connecting microcontrollers to peripheral buses in demanding environments.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the OE input affect bus isolation?

When the output-enable (OE) input is asserted high, the device disables its outputs, effectively isolating the A and B buses from each other.

What determines the direction of data transmission?

The logic level at the direction-control (DIR) input determines whether data flows from the A bus to the B bus or vice versa.
