Product details
Overview
MC74HC1G32DFT1 from onsemi is a single 2-input OR gate in SC-88A (SOT-353) package, fabricated with silicon gate CMOS technology. It delivers high-speed operation (tPD = 7 ns typ at VCC = 5 V), ±2 mA symmetrical output drive, and operates across −55°C to +125°C for automotive and industrial logic interfacing.
For engineers reviewing the MC74HC1G32DFT1 datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 qualification, SC-88A 5-pin footprint, balanced propagation delays (tPLH = tPHL), low ICC (≤1 µA max at 25°C), and guaranteed VIH/VIL thresholds across 2.0–6.0 V supply range.
Technical Context
The MC74HC1G32DFT1 implements a single 2-input positive-logic OR function using buffered CMOS stages to ensure high noise immunity and stable rail-to-rail output swing. Its internal design includes input protection diodes, symmetrical output impedance (IOH = IOL = 2 mA), and latchup immunity (±100 mA per JESD78 Class II).
It supports wide VCC operation from 2.0 V to 6.0 V with defined VIH (≥1.5 V at VCC = 2.0 V) and VIL (≤0.5 V at VCC = 2.0 V), enabling interoperability with 3.3 V and 5 V logic families. Propagation delay remains ≤25 ns over full temperature range (−55°C to +125°C) at VCC = 5 V and CL = 15 pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 6.0 V - supports mixed-voltage system interfacing without level shifters |
| tPD (Typ) | 7 ns at VCC = 5 V, CL = 15 pF - enables timing-critical combinational logic paths in sub-100 MHz domains |
| IOH/IOL | ±2 mA - sufficient to drive one 74HC input or small capacitive loads (<30 pF) directly |
| VIH/VIL | VIH ≥ 1.5 V (VCC = 2.0 V); VIL ≤ 0.5 V - ensures reliable logic recognition across voltage corners |
| Operating Temp | −55°C to +125°C - qualified for under-hood automotive and extended industrial environments |
| ESD Rating | HBM 2000 V, CDM 1000 V - meets robustness requirements for automated assembly and field operation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G32DBVR | Lower VCC min (1.65 V), faster tPD (3.7 ns typ), but only rated to +85°C | Not suitable for extended temperature or automotive use; better for portable consumer electronics | Select when operating below 2.0 V or requiring <5 ns delay, but verify thermal environment limits |
| 74AUP1G32GW,125 | Ultra-low power (ICC ≤ 0.9 µA), wider VCC (0.8–3.6 V), but max VCC = 3.6 V and no AEC-Q100 rating | Limited to low-voltage embedded systems; lacks automotive qualification and 5 V compatibility | Prefer for energy-harvesting or coin-cell-powered devices where 5 V operation is unnecessary |
Compared with SN74LVC1G32DBVR and 74AUP1G32GW,125, the MC74HC1G32DFT1 uniquely combines AEC-Q100 qualification, 2.0–6.0 V operation, and −55°C to +125°C capability-making it the only choice for safety-critical automotive and extended-temperature industrial OR logic.

FAQ
What is the maximum operating temperature for MC74HC1G32DFT1?
The MC74HC1G32DFT1 is rated for operation from −55°C to +125°C junction temperature. Its AEC-Q100 qualification confirms suitability for automotive under-hood applications and extended industrial environments where ambient temperatures exceed +105°C. Thermal resistance (θJA) is 377°C/W in SC-88A package, requiring appropriate PCB copper area for heat dissipation at elevated ambient conditions.
Does MC74HC1G32DFT1 support 3.3 V logic systems?
Yes, MC74HC1G32DFT1 fully supports 3.3 V logic systems. At VCC = 3.3 V, it guarantees VIH ≥ 2.1 V and VIL ≤ 0.9 V, ensuring compatibility with standard 3.3 V CMOS outputs. Propagation delay remains ≤20 ns over −40°C to +85°C, and output drive (±2 mA) is sufficient to interface with downstream 74HC or LVC inputs without external buffering.
Is MC74HC1G32DFT1 pin-compatible with other SC-88A logic gates?
MC74HC1G32DFT1 follows the standard SC-88A pinout for single-gate logic: Pin 1 = A, Pin 2 = B, Pin 3 = GND, Pin 4 = Y, Pin 5 = VCC. This matches industry-standard assignments for 5-pin logic gates (e.g., MC74HC1G00, SN74LVC1G08), enabling layout reuse across functionally distinct but footprint-identical devices in the same family.
What is the ESD robustness of MC74HC1G32DFT1?
The MC74HC1G32DFT1 provides HBM ESD withstand voltage of 2000 V and CDM ESD withstand voltage of 1000 V, tested per ANSI/ESDA/JEDEC JS-001-2017 and JESD22-C101-F respectively. These ratings meet IPC/JEDEC standards for automated SMT assembly and field reliability in industrial and automotive end equipment.
Can MC74HC1G32DFT1 operate at 2.0 V supply?
Yes, MC74HC1G32DFT1 is fully specified down to VCC = 2.0 V. At this voltage, it guarantees VIH ≥ 1.5 V and VIL ≤ 0.5 V, with propagation delay ≤100 ns (−40°C to +85°C). The device maintains rail-to-rail output swing and retains its ±2 mA drive strength, making it suitable for low-voltage battery-powered systems where 2.0 V represents end-of-life cell voltage.
