Active production — no lifecycle risk on this BOM line
The SN74LV32ADBR: ROHS3 compliance is confirmed, so no exemption expiry or material-declaration gap exists for EU or similar regulatory markets.
Supply voltage and temperature — the operating envelope
A system that sees 105°C on a hot factory floor still has 20°C of margin before the upper limit. Quiescent current maxes at 20 µA across the supply range, so in a battery-backed or always-on section the gate's own draw is negligible compared to the microcontroller's sleep current.
Speed and drive — what 7.5 ns and 12 mA mean for the signal path
Maximum propagation delay is 7.5 ns at 5V with a 50 pF load. This sets the data-rate ceiling for the logic path — at a 50% duty cycle the minimum pulse width the gate can pass cleanly is roughly twice the propagation delay, so 15 ns or about 33 MHz. For a SPI clock running at 20 MHz the margin is comfortable; for a 50 MHz clock the path would need a faster family like 74LVC or 74AHC. Output drive is 12 mA source and 12 mA sink at the rated VOH and VOL levels. This is enough to drive three or four standard LSTTL inputs or a short PCB trace, but not a long backplane or a 50-ohm terminated line — those need a buffer or a line driver.
Package and board-fit — 14-SSOP footprint
The 0.0256-inch pin pitch is fine-pitch enough to require a soldermask-defined pad, but the 1.27 mm standoff gives enough clearance for a standard no-clean flux residue to be washed out under the body. Available in Tape & Reel and Cut Tape options — the reel format suits automated pick-and-place for production volumes, while Cut Tape works for prototype or low-quantity builds without committing to a full reel.
Logic function — quad 2-input OR gate
Four independent 2-input OR gates in one package. The input logic thresholds are 0.5 V low and 1.5 V high at 5V supply, so a standard 3.3V CMOS output (VOH ~3.0V, VOL ~0.4V) is recognised correctly without external biasing.
