Six-bit register with master reset — what it is and where it fits
The Texas Instruments SN74LV174APW is a 6-bit D-type flip-flop with a master-reset function, positive-edge triggered, and non-inverted outputs. It belongs to the 74LV family — low-voltage CMOS logic that operates from 2V to 5.5V. The 180 MHz clock frequency covers fast parallel buses, SPI clock lines, or address latching in a moderate-speed controller. The industrial temperature range (-40°C to 85°C) covers motor drives, outdoor telecom cabinets, and factory-floor I/O modules.
12 mA output drive — enough for standard fan-out
Each output can source or sink 12 mA. That drives a handful of 74LV or 74HC inputs, a small LED, or a relay-driver transistor base. It is not a heavy line driver — if you need to push a long backplane trace or a 50-ohm terminated line, plan on a buffer. The quiescent current is only 20 µA, so the part does not waste power when idle.
Active production — no LTB pressure
That means no last-time-buy scramble, no forced redesign to a different footprint. For a BOM line that needs a reliable 6-bit register, this part is a stable choice.
