4-bit bus buffer with 3-state control
The 74FCT163244APAG is a 4-element, 4-bit buffer from the 74FCT series, meaning it packs sixteen bits of non-inverting buffering into a single 48-TSSOP package. Each element drives 8 mA high and 24 mA low, which is enough to fan out to multiple CMOS loads on a backplane or to drive the inputs of a downstream FPGA bank without an external line driver. The 3-state output control lets you isolate the bus when the device is deselected — critical in shared data-path designs where multiple peripherals talk over the same traces. The 48-TFSOP package with 0.240-inch body width is a fine-pitch surface-mount footprint — the 0.50 mm lead pitch demands careful PCB routing and a solder-paste stencil matched to the land pattern.
ROHS3 compliant covers the full RoHS exemption set, including lead in solder joints, which simplifies EU and UKCA market entry without an exemption review.
