Each gate performs the Boolean OR operation: the output is high when at least one input is high. This is a fundamental building block for glue logic, signal gating, and combinatorial control paths. With four circuits on one die, the part replaces four discrete OR-gate packages or consolidates a PAL/GAL macrocell in low-density designs. ## Supply voltage and temperature grade — where this part fits The input logic levels scale with Vcc: low threshold is 0.5V to 1.8V, high threshold is 1.5V to 4.2V, so the gate interprets standard CMOS and TTL levels correctly across the supply range. The 2 µA max quiescent current means the part adds negligible standby draw in battery-powered or always-on subsystems. ## Propagation delay and output drive — timing budget for the signal path Maximum propagation delay is 17 ns at 6V supply with a 50 pF load. At 5V the delay is typically 12-14 ns, which sets the maximum toggle rate around 30-40 MHz in a clean layout — enough for SPI clock gating, address decoding, or reset sequencing, but not for high-speed parallel buses. The symmetrical drive strength means rise and fall times are balanced, reducing skew in clock-gating applications. ## Package and compliance — board-fit and regulatory readiness The 14-TSSOP package (supplier device package 14-TSSOP) has a 4.40 mm body width and 0.65 mm pin pitch. The footprint matches standard TSSOP-14 land patterns; the 0.173-inch (4.40 mm) width is narrower than SOIC-14 (3.91 mm vs 6.00 mm), so a layout change is required when migrating from SOIC to TSSOP. ROHS3 compliant per TI's certification, with no restricted substances above the threshold.","metaTitle":"SN74HC32PW Texas Instruments 74HC Quad OR Gate, 14-TSSOP","metaDescription":"Texas Instruments SN74HC32PW quad 2-input OR gate, 74HC series, 2V-6V supply, 17ns delay, -40°C to 85°C, 14-TSSOP.
