It operates from a 4.5 V to 5.5 V supply and accepts TTL-compatible input levels (low 0.8 V, high 2 V). Four independent OR gates share the same supply and ground, giving you four 2-input OR functions in one 14-pin SOIC footprint. This part is rated for the full military temperature range of -55°C to 125°C, making it a fit for avionics, satellite, downhole, or any high-reliability environment where commercial-temperature parts would derate. ## Speed and drive – what the 24 ns and 4 mA mean Maximum propagation delay is 24 ns at 4.5 V with a 50 pF load. Output drive is 4 mA source and 4 mA sink. ## Temperature grade – full military range Rated -55°C to 125°C operating temperature. This is the full military range, so the part can be used in avionics, missile guidance, satellite, downhole drilling, or any environment where the board sees extreme cold or heat. No need to source a separate screened or MIL-STD part for temperature alone. The commercial/industrial SN74AC32DR is only rated -40°C to 85°C, so if your design requires 125°C, the CD74HCT32M is the correct choice. ## Lifecycle and sourcing Texas Instruments lists the CD74HCT32M as Active, ROHS3 compliant. No end-of-life notice or last-time-buy window is in effect.","metaTitle":"CD74HCT32M OR Gate, 4-Ch 2-In, 14-SOIC, 74HCT Series","metaDescription":"CD74HCT32M quad 2-input OR gate, 4.5V–5.5V supply, -55°C to 125°C range, 24ns prop delay.
