Package and mounting — legacy DIP, still on the board
Housed in a 16-pin DIP with 0.300-inch (7.62 mm) row spacing, the SN74F174AN is a through-hole part. That 16-PDIP footprint matches legacy sockets and prototyping boards; if your BOM is moving to SMT, the 74F174 family includes SOIC variants, but this exact order code is DIP only. The tube shipment is standard for through-hole logic — no reel, no carrier tape.
Output drive and quiescent draw
Output current ratings are 1 mA source, 20 mA sink per pin — enough to drive a TTL input or a low-current LED, but not a relay coil or bus transceiver without a buffer. The 45 mA quiescent supply current (Iq) is typical for a six-bit 74F register running at speed; it adds up across multiple devices on a 5V rail, so budget the total Iq for your power supply.
