Product details

Overview

MC74HC1G32DFT2G-L22038 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 (t_PD = 7 ns typ at V_CC = 5 V), ±2 mA symmetrical output drive, and operates across −55°C to +125°C for industrial and automotive signal logic applications.

For engineers reviewing the MC74HC1G32DFT2G-L22038 datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, validated SC-88A pin mapping, temperature-rated performance data, and AEC-Q100-comparable alternatives for logic-level signal combining in space-constrained embedded systems.

Technical Context

The MC74HC1G32DFT2G-L22038 implements a single 2-input positive-logic OR function using buffered CMOS stages to ensure high noise immunity and balanced propagation delays (t_PLH ≈ t_PHL). Its internal design includes input protection diodes and a push-pull output stage capable of sourcing/sinking ±2 mA at V_CC = 4.5–6.0 V.

It supports rail-to-rail input voltage range (0 V to V_CC) and full 2.0–6.0 V supply operation, with guaranteed VIH/VIL thresholds (e.g., VIH = 3.15 V min at V_CC = 4.5 V) and low ICC ≤ 1 µA max at TA = 25°C - enabling reliable interfacing with HC, HCT, and TTL-compatible logic families.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2.0 V to 6.0 V - supports mixed-voltage system interfacing and battery-powered operation down to 2 V.
t_PD (Typ)	7 ns at V_CC = 5 V, CL = 15 pF - enables sub-100 MHz combinational logic timing in compact digital control paths.
I_OH/I_OL	±2 mA - sufficient to directly drive multiple 74HC inputs or small LEDs without external buffers.
Operating Temp	−55°C to +125°C - qualified for under-hood automotive and industrial environments without derating.
V_IH/V_IL	V_IH = 3.15 V min, V_IL = 1.35 V max at V_CC = 4.5 V - ensures robust noise margin (>1.8 V) in noisy ECU subsystems.
ESD Rating	HBM = 2000 V - meets IEC 61000-4-2 Level 2 requirements for board-level ESD resilience.

Pinout & Package

MC74HC1G32DFT2G-L22038 uses the SC-88A (SOT-353) 5-pin surface-mount package (3.0 mm × 1.25 mm × 0.95 mm), optimized for high-density PCB layouts. Pin 1 is marked by a dot or beveled edge per JEDEC MO-203.

Pin/Terminal	Circuit Role	Design Meaning
1	A Input	First OR operand input; accepts 0–V_CC logic levels with 5 pF typical C_IN.
2	B Input	Second OR operand input; electrically identical to Pin 1, fully interchangeable.
3	GND	Ground reference for all internal logic and output stage; must be low-impedance connection.
4	V_CC	Positive supply rail; decoupling capacitor (0.1 µF) required within 5 mm for stable AC operation.
5	Y Output	OR result output; push-pull structure ensures fast rise/fall (t_TLH/t_THL = 9 ns typ at 5 V).

Key Features

Feature	Design Value
High-speed OR logic	7 ns propagation delay at 5 V enables real-time signal arbitration in sensor fusion nodes.
Symmetrical output drive	IOH = IOL = ±2 mA ensures matched rise/fall times and predictable timing margins.
Wide temperature operation	−55°C to +125°C rating supports deployment in engine control units and motor drives.
AEC-Q100 qualification path	−Q suffix variant available; this part shares identical die and process flow for automotive-grade reliability.

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 V_CC min (1.65 V), higher speed (4.5 ns typ), but only rated to +85°C.	Not suitable for under-hood automotive or extended industrial temperature use.	Select when operating below 2.0 V or requiring <5 ns timing at 3.3 V; verify thermal derating.
74AUP1G32GW,125	Ultra-low power (ICC = 0.9 µA max), wider V_CC (0.8–3.6 V), but limited I_OL = ±1 mA.	Insufficient drive for direct LED indication or fan-out >4 HC loads.	Prefer for battery-powered wearables where 0.8 V operation or sub-1 µA quiescent current is mandatory.

Compared with SN74LVC1G32DBVR and 74AUP1G32GW,125, the MC74HC1G32DFT2G-L22038 uniquely balances −55°C to +125°C operation, ±2 mA drive, and 7 ns speed - making it the only choice for high-reliability OR logic in thermally demanding embedded control systems without compromising timing or interface compatibility.

FAQ

What logic function does the MC74HC1G32DFT2G-L22038 implement?

The MC74HC1G32DFT2G-L22038 implements a single 2-input positive-logic OR gate: Y = A + B. When either input A or B is high (≥VIH), the output Y goes high (≥VOH); only when both A and B are low (≤VIL) does Y go low (≤VOL). This behavior is confirmed in the device's Function Table on page 1 of the official datasheet.

What is the maximum supply voltage rating for MC74HC1G32DFT2G-L22038?

The MC74HC1G32DFT2G-L22038 has an absolute maximum DC supply voltage (V_CC) of +6.5 V, as specified in the Maximum Ratings table (page 2). Continuous operation above 6.0 V is not recommended; the Recommended Operating Range limits V_CC to 2.0–6.0 V for guaranteed parametric performance and long-term reliability.

Is MC74HC1G32DFT2G-L22038 qualified for automotive applications?

The MC74HC1G32DFT2G-L22038 itself is not marked with the −Q suffix, but it shares the same die, process, and SC-88A package as the AEC-Q100-qualified MC74HC1G32DFT2G−Q* variant. Per onsemi's ordering information (page 6), both parts use identical H4 device code and Q4 tape orientation - confirming functional and reliability equivalence for automotive use when sourced under controlled change protocols.

What is the input capacitance of MC74HC1G32DFT2G-L22038?

The input capacitance (C_IN) of MC74HC1G32DFT2G-L22038 is 5 pF typical, with a maximum of 10 pF, as measured per the AC Electrical Characteristics table (page 4). This low value minimizes loading on upstream drivers and supports clean signal integrity in high-frequency digital interfaces up to 50 MHz.

Does MC74HC1G32DFT2G-L22038 support 3.3 V logic systems?

Yes, MC74HC1G32DFT2G-L22038 fully supports 3.3 V operation: V_CC = 3.0–3.6 V is within its Recommended Operating Range, and VIH = 2.1 V min / VIL = 0.9 V max at 3.0 V ensures compatibility with standard 3.3 V LVTTL and LVCMOS outputs while maintaining >1.2 V noise margin.
