SNJ54ABT245AJ

Buffers, Drivers, Receivers, Transceivers Overview

The SNJ54ABT245AJ is an octal bus transceiver with 3-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 temperature range from -55°C to 125°C. The device features high-drive outputs capable of sourcing -32 mA and sinking 64 mA. Propagation delays are specified at a maximum of 3.8 ns for low-to-high transitions and 4.2 ns for high-to-low transitions under standard test conditions.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'AJ' corresponds to the CDIP-20 package configuration. Confirm that the MIL-PRF-38535 compliance status aligns with project requirements, as parameter testing protocols differ for this qualification level compared to commercial variants. Ensure environmental specifications match the intended operational environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high drive strength and wide temperature operation are required. The ABT series offers faster switching speeds compared to older ALS or LS families. Verify pin compatibility if replacing legacy devices, noting the specific pinout for the CDIP package. Consider thermal management requirements due to the high output current capabilities.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN54/74ABT245A/B family of octal bus transceivers. The SNJ prefix indicates a military-grade version produced under strict quality controls. It shares functional similarities with other ABT series devices but is distinguished by its ruggedized packaging and extended temperature rating suitable for harsh environments.
