It sits in the signal path between a data bus and a load that needs current gain or isolation — typical roles include buffering address or data lines on a backplane, driving a bank of LEDs, or fanning out a clock or control signal to multiple destinations. The part is listed under Discrete Semiconductors, which in this context means it is a single-function logic buffer, not a multi-function gate array. The 4-bit width matches the width of a nibble or a low-order byte on an 8-bit bus. ## Lifecycle and compliance — what to expect on the BOM The part is RoHS non-compliant. This means it contains lead (Pb) in the solder finish or die-attach material, which is typical for legacy Schottky TTL parts originally qualified before the RoHS directive. If your BOM requires RoHS compliance, a tin-lead exemption or a lead-free alternative may be needed. ## Package and procurement note The DM74S240J ships in Bulk packaging — loose tubes or trays, not tape-and-reel. This is the standard format for through-hole DIP parts and suits manual assembly or low-volume production runs. For current pricing and lead time, the part is quoted to order against an RFQ.","metaTitle":"DM74S240J Texas Instruments Bus Driver, 4-Bit, TTL","metaDescription":"DM74S240J Texas Instruments 4-bit bus driver, TTL logic.
