Product details

The Texas Instruments SN74ABT244N is a 4-bit bus driver from the ABT (Advanced BiCMOS Technology) series, designed for high-speed line driving in digital systems. It buffers and drives bus lines, providing the current and noise margin needed for backplane, memory interface, and peripheral bus applications. The ABT family balances speed and power, making this part suitable for industrial control, telecom infrastructure, and computing equipment where 5 V logic is still in use.

The RoHS non-compliant designation is a material constraint: if your assembly line requires lead-free solder, this part will need an exemption or a waiver — verify your process before committing the BOM line.

For a production-quantity requirement or a prototype sample, submit an RFQ and we will return a firm offer with lead time.

What is the equivalent of SN74ABT244N?

The evidence does not list a direct pin-compatible equivalent or second-source alternate for the SN74ABT244N. The peer parts 74ACT16833DL, SNJ54ALS574AFK, and SNJ95161BFK are different device types (bus transceiver, octal flip-flop, and bus transceiver respectively) and are not functional substitutes. For a drop-in replacement, verify the exact logic family, package, and pinout against your design.
