Quad buffer with 3-state outputs for bus isolation
The CD74HC125M96 is a quad non-inverting buffer from the 74HC family, each channel offering a 3-state output that goes high-impedance when the corresponding output-enable pin is pulled high. This makes it a standard part for driving shared data buses or multiplexed lines where multiple sources need to release the bus without contention. Supply range runs from 2V to 6V, covering both 3.3V and 5V logic rails. The 7.8mA source/sink drive per output is enough to light an LED or drive a single TTL load, but for heavier fan-out you'll want a bus transceiver with higher current capability.
14-SOIC package — rework-friendly footprint
Housed in a 14-SOIC (0.154-inch body width, 3.90mm), this is one of the easiest small-outline packages to hand-rework. The 1.27mm pin pitch gives plenty of room for a fine-tip iron or hot-air nozzle; pin 1 is clearly marked by a molded notch and a dot on the top surface. No thermal pad underneath, so no risk of hidden solder bridges. Available in Tape & Reel (TR) or Cut Tape (CT) — the reel format suits automated pick-and-place for volume builds, while cut tape works for prototype runs and bench stock.
Active production, full temperature range
Texas Instruments lists the CD74HC125M96 as Active with ROHS3 compliance. Rated for -55°C to 125°C ambient, so it handles industrial and automotive under-hood environments without derating. The 74HC logic family runs at CMOS levels with 2V to 6V supply, making it a drop-in for mixed-voltage boards that need a buffer between a 3.3V MCU and a 5V peripheral.
