It is designed for driving heavily loaded backplane or memory-array buses where the 32 mA source and 64 mA sink capability provide the fan-out to drive multiple TTL or CMOS loads without external buffers. ## Output drive and temperature range The 32 mA high-level and 64 mA low-level output currents are the headline numbers for bus-interface designs: the 64 mA sink handles the larger capacitive load of a multi-drop address/data bus, while the 32 mA source is sufficient for most TTL fan-in requirements. If your application runs above 85°C ambient, the 74FCT16244T family does not carry a wider-temperature variant in this package; plan for forced airflow or a derating review. The RoHS compliance status is listed as non-compliant — this is a legacy 5 V logic part manufactured before the RoHS transition, so it contains lead in the solder finish. If your assembly line is RoHS-exempt (industrial/telecom equipment under certain exemptions) or you are repairing legacy boards, this is not a blocker. For new RoHS-mandated designs, verify your exemption or look at the lead-free suffix variants in the same family.","metaTitle":"74FCT16244TPA Buffer/Line Driver, 32/64 mA, 48-TSSOP","metaDescription":"74FCT16244TPA 16-bit non-inverting buffer/line driver with 3-state outputs. 4.5V-5.5V supply, 32mA/64mA drive, -40°C to 85°C.
