The wide supply range from 1.65V to 3.6V lets it bridge 1.8V, 2.5V, and 3.3V logic domains without extra level shifters — a common requirement in mixed-voltage boards where a memory controller talks to a 3.3V peripheral over a shared data bus. ## 1.65V to 3.6V supply — what it buys you The 1.65V minimum supply means this buffer runs directly off a 1.8V rail, which is the core voltage for many modern FPGAs and SoCs. At the top end, 3.6V covers a 3.3V supply with margin for transients. That span eliminates the need for a dedicated 3.3V-tolerant input stage when the buffer sits between a 1.8V controller and a legacy 3.3V peripheral — the device itself adapts to whichever rail it's powered from. The 24mA symmetric drive at both logic levels is enough to drive a heavily loaded parallel bus or a bank of LEDs through a resistor, but the real win is the consistent drive strength regardless of whether the output is high or low, which keeps rise and fall times matched on the bus. ## 48-SSOP package — rework and layout notes The 48-BSSOP body (7.50mm wide, 0.295\" pitch) is a standard SSOP footprint that reflows cleanly with a hot-air station if you preheat the board to 100°C. The 0.635mm lead pitch is forgiving enough for hand-soldering with a fine tip, but the 48 leads mean you'll want a flux pen and a clean iron. No thermal pad underneath, so all heat dissipation goes through the leads; keep the trace widths to the supply pins at 12 mil or wider for the 24mA per-output case when all 16 channels are switching simultaneously. The surface-mount SSOP footprint is shared across many 74ALVC and 74LVC bus-interface parts, so a board laid out for this buffer can often accept a transceiver variant without a respin. The 74ALVC family is mature and widely second-sourced. For a drop-in buffer replacement, stay within the 74ALVC or 74LVC families.","metaTitle":"SN74ALVC16244ADLR 16-bit Buffer, 1.65V–3.6V, 48-SSOP","metaDescription":"TI SN74ALVC16244ADLR 16-bit non-inverting buffer with 3-state outputs.
