Symmetric 24 mA source and sink drive per output means it can fan out to multiple loads on a shared address or data bus without needing external line drivers. The 3-state outputs let multiple buffers share the same bus lines — the enable per 4-bit bank gives granular control over which section drives the bus at any cycle. Housed in a 48-TFSOP (6.10 mm body width) and also listed with a 48-TSSOP supplier device package, this is a fine-pitch SMD part — 0.5 mm pin pitch typical for the TSSOP family. The board footprint is not compatible with wider SOIC or DIP layouts; a new PCB layout or an adapter is needed if replacing an older 16-bit buffer in a larger package. No official second-source or successor is documented; the 74ALVCH family is a mature logic series and this variant is a standard catalog item.","metaTitle":"SN74ALVCH16244DGGR 16-bit buffer, 1.65V–3.6V, 48-TSSOP","metaDescription":"TI SN74ALVCH16244DGGR 16-bit buffer with 3-state outputs, 24 mA drive, 1.65V–3.6V supply, 48-TSSOP.

The SN74LVC1G125YZPR is a single-bit buffer in a tiny 5-pin package (DSBGA), while the SN74ALVCH16244DGGR is a 16-bit buffer in a 48-pin TFSOP. The function is similar (non-inverting, 3-state), but the footprint, pinout, and channel count are completely different.
