It belongs to the 74ALVTH family, designed for high-speed bus interfaces where signal isolation and bidirectional control are needed.
Supply voltage — dual-range flexibility for mixed-voltage designs
Output drive — 32 mA source, 64 mA sink
With 32 mA source and 64 mA sink capability per output, this buffer can drive heavily loaded buses or multiple downstream inputs while maintaining signal integrity. The asymmetric sink strength is typical of ALVT logic and suits terminated backplanes where the pull-down network absorbs more current than the pull-up. Check the total package dissipation when all 16 outputs are sinking simultaneously — the 48-SSOP's thermal impedance is the limit, not the per-pin rating.
Package and footprint — 48-SSOP (BSSOP body)
Housed in a 48-BSSOP package with 0.295-inch (7.50 mm) body width, the SN74ALVTH16240DL uses a standard SSOP-48 footprint.
It is ROHS3 compliant. No LTB risk or allocation concern for new designs.
