SN54ABTH16244 and SN74ABTH16244 are 16-bit buffers/drivers with 3-state outputs. They feature state-of-the-art EPIC-ΙΙB BiCMOS design that significantly reduces power dissipation. The latch-up performance exceeds 500 mA per JESD 17. The typical VOLP (Output Ground Bounce) is less than 1 V at VCC = 5 V, TA = 25°C. The distributed VCC and GND pins minimize high-speed switching noise. The flow-through architecture optimizes PCB layout. The devices have high-drive outputs (-32 mA IOH, 64 mA IOL). Bus hold on data inputs eliminates the need for external pullup/pulldown resistors. ESD protection exceeds 2000 V per MIL-STD-883, Method 3015; exceeds 200 V using machine model (C = 200 pF, R = 0). Package options include plastic shrink small-outline (DL), thin shrink small-outline (DGG), thin very small-outline (DGV) packages, and 380-mil fine-pitch ceramic flat (WD) packages.
The SN54ABTH16244 and SN74ABTH16244 are 16‑bit buffers and line drivers featuring 3‑state outputs, high‑drive capability, and built‑in bus‑hold circuitry. They are offered in multiple packages (DGG, DGV, DL, WD) and are intended for memory address drivers, clock drivers, and bus‑oriented interfaces.
