The CD74HC4075M is a Texas Instruments triple 3-input OR gate from the 74HC series, packaged in a 14-SOIC surface-mount body (0.154" width, 3.90mm). It combines three independent OR gates, each with three inputs, in a single IC — a common building block for glue logic, status combining, or enable-path gating in mixed-signal and digital boards. Supply voltage spans 2V to 6V, making it usable in 3.3V and 5V systems without a separate level translator.
Parametric depth — what the numbers mean for your timing and drive
Maximum propagation delay is 17ns at 6V supply with a 50pF load. That sets the timing ceiling for a clean logic transition; at 5V the delay will be slightly higher, so budget accordingly in fast clock-enable or reset paths. Output drive capability is 5.2mA for both high and low states — enough to feed a CMOS input or a low-power LED, but not enough to directly drive a relay or optocoupler without a buffer. Quiescent current maxes at 2 µA, so the part adds negligible static power in battery-operated designs. Input logic levels follow the 74HC standard: low threshold between 0.5V and 1.8V, high threshold between 1.5V and 4.2V (depending on supply). This means a 3.3V microcontroller output will drive the gate reliably at 5V supply, but a 1.8V logic source may not reach the high threshold at the 5V rail — verify the swing against your upstream driver.
Lifecycle and sourcing posture
Packaging is Tube, which is typical for low-volume prototyping or small-batch production. For tape-and-reel quantities, check the ordering options under the same base part number.
