2.8 ns propagation delay at 3.3 V — what it means for the bus
The Texas Instruments SN74ALVC32PW is a quad 2-input OR gate from the 74ALVC family, built for low-voltage, high-speed logic. It combines four independent OR gates in a single 14-TSSOP package, each capable of sinking or sourcing 24 mA. The headline rating is the 2.8 ns maximum propagation delay at 3.3 V with a 50 pF load — that's fast enough to keep up with a 100 MHz+ clocked bus without adding a full clock cycle of skew. The 1.65 V to 3.6 V supply range lets it bridge 1.8 V and 3.3 V logic domains directly, so it can sit on a mixed-voltage backplane or a battery-powered sensor board without a level translator.
Supply range and temperature — where this gate fits
The 1.65 V minimum supply means this part works with 1.8 V nominal logic (like many modern MCUs and FPGAs) while still tolerating a 3.3 V rail. The -40°C to 85°C temperature range covers industrial control cabinets, outdoor telecom gear, and factory-floor sensors. It is not rated for the full automotive under-hood temperature range (125°C), so if the BOM calls for AEC-Q100 or a 125°C junction, the 74LVC siblings (SN74LVC08ADR or SN74LVC10AD) are the next step up in temperature grade.
Quiescent current and output drive
The 10 µA maximum quiescent current is low enough that this gate can be left powered on a battery-backed rail without draining the cell. The 24 mA symmetric output drive is strong for a 1.65 V to 3.6 V part — it can drive a string of downstream CMOS inputs or a short PCB trace without a buffer. The input logic thresholds (low at 0.7 V to 0.8 V, high at 1.7 V to 2 V) are TTL-compatible, so it interfaces cleanly with older 5 V-tolerant logic families when the supply is 3.3 V.
Lifecycle and compliance
It is ROHS3 compliant, so it passes the EU material restrictions without an exemption. The 14-TSSOP package is a common footprint shared with other 74-series logic gates, making board-level swaps straightforward if a second-source or alternate function is needed.
Sourcing reality for the BOM line
This is a current-production standard logic part, widely stocked across distribution. For a BOM line that needs a fast quad OR gate in a small TSSOP-14 footprint, the SN74ALVC32PW is a straightforward fit.
