Each of the four elements passes a single bit, and the output enable lets you float the pin — useful for shared buses where multiple drivers talk on the same line. ## Output drive and what it can't do Each output sources or sinks 7.8mA, which is typical for 74HC CMOS — enough to drive a handful of CMOS logic inputs or a low-power LED with a series resistor, but not a relay coil or a high-current bus transceiver. If you need more fan-out, plan on a buffer stage or a part with higher drive like the 74ABT family (32mA per pin). The 3-state output is high-impedance when the enable is low, so multiple buffers can share a data line without contention. ## Package and hand-solderability Housed in a 14-SOIC package with 1.27mm pitch, this is a hand-solderable part if you have a fine tip and steady hands — no hot-air gun required. The 0.154-inch body width fits standard SOIC footprints, and the surface-mount profile keeps board height low. No exposed thermal pad to worry about; just route the supply decoupling close to pins 7 (GND) and 14 (VCC).","metaTitle":"CD74HC126M 74HC Buffer, Non-Inverting, 3-State","metaDescription":"CD74HC126M 74HC quad buffer with 3-state outputs, 2V to 6V supply, -55°C to 125°C range.
