It operates on a 4.5 V to 5.5 V supply and delivers 24 mA symmetric output drive — enough to fan out to multiple TTL loads or drive short PCB traces without a buffer. The 9 ns propagation delay at 5 V, 50 pF sets the timing budget for bus-oriented logic where every nanosecond of gate delay matters. The -40°C to 85°C industrial temperature range suits it for outdoor telecom cabinets, factory-floor PLC I/O modules, and power-supply sequencing logic where the ambient stays above freezing but never soaks at automotive under-hood extremes. ## 9 ns propagation delay — timing margin in a 5 V bus The 9 ns max propagation delay at 5 V, 50 pF is the headline timing spec. The 74AC variant (SN74AC32DR) clocks 7.5 ns at the same load. ## Active lifecycle — no LTB risk for this BOM line The SN74ACT32D carries an Active product status with ROHS3 compliance. For a BOM freeze or a long-run production build, this means no last-time-buy scramble. ## Supply and logic thresholds — 5 V-only, TTL-compatible inputs The supply range is 4.5 V to 5.5 V. Input logic low is 0.8 V max, high is 2 V min, which makes it directly compatible with TTL output levels.","metaTitle":"SN74ACT32D OR Gate IC, 4-Ch 2-Input, 14-SOIC, 9ns at 5V","metaDescription":"TI SN74ACT32D quad 2-input OR gate, 74ACT series, 4.5V-5.5V supply, 24mA output, 9ns prop delay, -40°C to 85°C, 14-SOIC.
