16-bit bus buffer with 1.65V to 3.6V supply range
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 24mA symmetric output drive at both high and low levels handles moderately loaded backplane or memory-interface lines without external buffers. The industrial temperature range of -40°C to 85°C covers most factory-floor and outdoor telecom enclosures.
Supply voltage and drive — what they mean for the BOM
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.
Package and footprint for PCB layout
The device is supplied in a 48-TFSOP package with a 6.10mm body width, and the supplier device package is listed as 48-TSSOP. 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. The part is surface-mount only; no through-hole variant exists.
Lifecycle and compliance status
The SN74ALVC16244ADGGR is listed as Active with ROHS3 compliance. The ROHS3 rating covers the full exemption list, which simplifies compliance documentation for EU and global shipments.
