It buffers eight signals with non-inverting pass-through and 3-state outputs, meaning you can tie multiple drivers to the same bus and disable this one without loading the line. The headline spec is the output drive: 15 mA source, 64 mA sink at the output pins. If your board runs a 5 V rail with ±10 % tolerance, the low end at 4.5 V is below this part's minimum — the regulator needs to hold regulation within 5 %. Two elements of four bits each means the eight channels are split into two independent 4-bit nibbles, each with its own output-enable control. That lets you gate half the bus while the other half drives — handy for byte-wide data paths where you need separate control over the upper and lower nibble. ## 20-SSOP vs 20-QSOP — two package names, same footprint These are the same mechanical footprint — the QSOP is the tighter-lead-frame variant of the SSOP body. Either way, the PCB land pattern is a 20-pin SOIC-width body with 0.025\" (0.635 mm) pitch. Surface-mount only — no through-hole option. RoHS non-compliant per the lifecycle record. If your BOM requires RoHS-10 exemption or you are building for a RoHS-exempt market (military, medical implant, some industrial), this part fits. For full RoHS compliance, look at the lead-free suffix variants in the same FCT244 family.","metaTitle":"IDT74FCT244TQ Renesas Buffer, Non-Inverting, 15/64mA","metaDescription":"IDT74FCT244TQ Renesas octal buffer/line driver, 4.75V-5.25V, 15mA/64mA output drive, 20-SSOP.
