Product details
Overview
MC74HC32ADR2G-Q from onsemi is a quad 2-input OR gate in SOIC-14 package, operating across 2.0–6.0 V supply, delivering 10 LSTTL load drive capability with propagation delay as low as 13 ns at 6.0 V, used for logic-level signal combining in automotive control modules and industrial PLC I/O conditioning.
For engineers reviewing the MC74HC32ADR2G-Q datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, validated AEC-Q100 qualification status, confirmed SOIC-14 pin mapping, and real-world timing and drive specifications per JEDEC 7A compliance.
Technical Context
The MC74HC32ADR2G-Q implements four independent CMOS OR gates (Y = A + B) using high-performance silicon-gate technology, with inputs compatible with standard CMOS outputs and pullup-resistor-enabled LSTTL interfacing. It features rail-to-rail output swing and guaranteed operation from –55 °C to +125 °C.
Its architecture supports direct interface to CMOS, NMOS, and TTL loads without level-shifting, and includes low input current (±0.1 µA typical), high noise immunity, and 10 pF max input capacitance - all specified under AEC-Q100 stress test conditions for automotive use.

Applications
| Automotive Body Control Module | Industrial PLC Digital Input Conditioning |
|---|---|
|
Use Scenario: Combining multiple door-lock request signals into a single enable line for actuator driver ICs. IC Role / Device Role / Timing Role: Logic-level OR combiner - aggregates asynchronous mechanical switch inputs before latching or MCU sampling. Use Value: Eliminates need for discrete diode-OR networks, reducing board space and improving noise margin over 12 V systems. |
Use Scenario: Validating presence of any active field sensor (limit switch, proximity, photoelectric) in a safety-critical zone. IC Role / Device Role / Timing Role: Real-time OR gate - produces immediate high output if any of four sensors asserts, feeding directly to safety controller. Use Value: Sub-15 ns propagation ensures <100 ns response time from sensor activation to safety system alert - critical for Category 3 PLd compliance. |
| Medical Infusion Pump Status Monitoring | Consumer Appliance Door Interlock Logic |
|
Use Scenario: Detecting failure of any one of three redundant motor stall detection circuits to trigger immediate pump halt. IC Role / Device Role / Timing Role: Fault-aggregation OR gate - wired to monitor open-collector outputs of three independent current-sense comparators. Use Value: Guaranteed 125 °C operation allows placement near motor drivers; ±5.2 mA drive interfaces directly to optocoupler LED anodes. |
Use Scenario: Enabling heating element only when both door latch and interlock switch are closed simultaneously - implemented via inverted OR (NOR) using external inverters. IC Role / Device Role / Timing Role: Core combinational logic block - forms part of dual-redundant safety path requiring two independent OR functions per door state. Use Value: AEC-Q100 qualification ensures long-term reliability in thermally cycled appliance enclosures; 2.0 V min VCC supports brown-out tolerant designs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC32DR | Same logic function and pinout; operates 2.0–6.0 V but not AEC-Q100 qualified; max TA = +85 °C industrial grade | Lacks automotive qualification and extended temperature support - unsuitable for under-hood or safety-critical use | Select SN74HC32DR only for cost-sensitive consumer or industrial boards where AEC-Q100 and 125 °C operation are not required. |
| MC74VHC32DT | Higher speed (8 ns @ 5 V), lower drive (±8 mA), same SOIC-14 footprint; AEC-Q100 qualified but only up to +105 °C | Marginally faster but reduced output current - may require buffering when driving >5 LSTTL loads | Choose MC74VHC32DT when sub-10 ns timing dominates over drive strength, and ambient temperature stays ≤105 °C. |
Compared with SN74HC32DR and MC74VHC32DT, the MC74HC32ADR2G-Q uniquely delivers full AEC-Q100 Grade 1 qualification, 125 °C operation, and 10 LSTTL drive in a single SOIC-14 package - making it the only option for automotive body electronics requiring both robustness and compatibility with legacy LSTTL subsystems.

FAQ
What is the maximum operating temperature for MC74HC32ADR2G-Q?
The MC74HC32ADR2G-Q is rated for continuous operation from –55 °C to +125 °C ambient temperature and is AEC-Q100 Grade 1 qualified. This specification is verified per JEDEC JESD22-A108 stress testing and applies across the full 2.0–6.0 V supply range. The MC74HC32ADR2G-Q maintains guaranteed timing and drive performance within this range without derating.
Is MC74HC32ADR2G-Q pin-compatible with standard LS32 devices?
Yes, the MC74HC32ADR2G-Q has identical pinout to the 74LS32, including VCC on pin 14 and GND on pin 7. Its inputs are compatible with standard CMOS outputs and, with appropriate pullup resistors, with LSTTL outputs. This allows direct substitution in existing LS32-based designs without PCB modification.
Does MC74HC32ADR2G-Q support 3.3 V logic systems?
Yes, the MC74HC32ADR2G-Q operates reliably at 3.3 V supply, with guaranteed VOH ≥ 3.15 V and VOL ≤ 0.26 V when sourcing/sinking 4.0 mA. Input thresholds scale with VCC, so VIH = 2.10 V and VIL = 0.90 V at 3.3 V - ensuring clean interfacing with 3.3 V microcontrollers and FPGAs.
What packaging format does MC74HC32ADR2G-Q ship in?
The MC74HC32ADR2G-Q ships in tape-and-reel format: 2500 units per reel, compatible with automated SMT placement equipment. The SOIC-14 package (Case 751A) uses standard 1.27 mm pitch, gull-wing leads, and Pb-free matte-tin plating per JEDEC J-STD-020 moisture sensitivity Level 1.
How does MC74HC32ADR2G-Q differ from MC74HC32ADR2G?
The MC74HC32ADR2G-Q includes the "–Q" suffix denoting AEC-Q100 qualification, PPAP capability, and unique site/control change requirements for automotive applications. While electrically identical to MC74HC32ADR2G, the –Q version undergoes additional process controls, lot traceability, and extended reliability testing per automotive standards.
