16-bit bus transceiver with 64 mA sink drive
The SN74ABT16245ADL is a 16-bit non-inverting transceiver from the 74ABT family, organized as two 8-bit elements with independent direction and output-enable controls. The 3-state outputs let it share a bidirectional data bus without contention — the high-impedance state isolates the driver when the part is not selected. The 64 mA sink figure is what matters for driving heavily loaded backplanes or long PCB traces — it keeps the low-level VOL within TTL thresholds even when fanning out to multiple loads.
Industrial temperature and 48-SSOP footprint
The lead pitch is 0.635 mm — a standard 0.65 mm pitch soldering profile works, but the narrow body requires careful stencil alignment to avoid solder bridging on the inner rows.
Active lifecycle and sourcing posture
Texas Instruments lists the SN74ABT16245ADL as Active (current production) and ROHS3 compliant. Sourced through authorized and independent distribution channels. The laser-etched date-code on the package body traces back to TI's assembly site — a clean provenance mark for buyers screening counterfeit stock.
Board-fit contrast vs. SN74ABT2245DW
The closest parametric peer in the same 74ABT family is the SN74ABT2245DW — a single-element 8-bit transceiver in a 20-SOIC package. The 16245ADL doubles the bus width (16 bits vs 8 bits) and uses a 48-SSOP footprint. A board originally laid out for the 2245DW cannot accept the 16245ADL without a layout change; the pinout and pitch are different.
