The Texas Instruments SN74ALVC16244ADGGR is a 16-bit buffer and line driver from the 74ALVC family, organized as four 4-bit elements with non-inverting outputs and 3-state control. It operates across a 1.65V to 3.6V supply range, making it suitable for mixed-voltage systems where a 1.8V or 2.5V core logic needs to drive a 3.3V bus, or where low-voltage operation reduces dynamic power.
The 1.65V to 3.6V supply window is the headline selection parameter. At 1.8V the part interfaces directly with low-voltage ASICs or FPGAs; at 3.3V it drives standard 3.3V logic families. The 24mA output current at both VOH and VOL is enough to drive a 50pF load at 100MHz+ with clean edges, but if your bus has more than eight loads or long traces, consider whether the 24mA symmetric drive still meets your signal-integrity budget — the part does not offer adjustable drive strength. The 3-state outputs allow bus sharing when the output-enable pins are gated.
These are the same mechanical footprint — TFSOP and TSSOP are often used interchangeably in TI documentation for this pinout. The 0.5mm lead pitch and 6.10mm width are standard for 48-pin TSSOP, so existing TSSOP-48 land patterns will match.
