Bus driver, ALVC/VCX/A — what the part number tells you
The 74ALVCH162244DL118: The '244' in the base number identifies a non-inverting 3-state output buffer — the kind you reach for when you need to drive a heavily loaded bus or isolate a data line without inverting the signal.
Supplied in Bulk (tube or tray), not tape-and-reel — a detail that matters if your pick-and-place feeder setup expects embossed carrier tape. The 48-pin SSOP body is a standard 0.635 mm pitch fine-pitch package. The ALVC/VCX/A series runs on a 2.3 V to 3.6 V core, but the I/O pins tolerate up to 5 V — so this driver can sit between a 3.3 V controller and a legacy 5 V peripheral without a level translator.
RoHS compliance is standard for this NXP logic family, but specific certification documents (REACH, conflict minerals, UL) should be confirmed at RFQ time — the part number alone doesn't encode the compliance revision level.
