What this triple OR gate brings to the board
The CD74HC4075PWT is a 74HC-series triple 3-input OR gate in a 14-TSSOP package. It takes three independent OR functions, each with three inputs, and delivers a standard 5.2 mA source/sink drive per output. Supply voltage spans 2V to 6V, covering the common 3.3V and 5V logic rails. The 2 µA max quiescent current means it adds negligible static draw in battery-powered or always-on sections.
Package and board-fit details
Housed in a 14-TSSOP (0.173", 4.40mm width) surface-mount package, the CD74HC4075PWT sits on a standard 0.65mm pitch footprint.
Switching performance and drive capability
Maximum propagation delay is 17 ns at 6V with a 50 pF load. That 17 ns ceiling sets the timing budget for the OR function in the signal path — cascading three such gates adds roughly 51 ns of delay, which matters for high-speed control or data latching. The 5.2 mA output current per channel drives standard CMOS and TTL loads, but it won't directly switch a relay or LED without a buffer.
If the CD74HC4075PWT is unavailable, a functionally equivalent 74HC4075 in the same 14-TSSOP package from another manufacturer will typically drop in without a board spin — confirm the input threshold and timing against your specific timing budget.
