Product details

Overview

MC74HC1G02DFT1G from onsemi is a single 2-input NOR gate in SC-88A (SOT-353) package, operating from 2.0 V to 6.0 V supply, with 7 ns typical propagation delay at 5 V and ±2 mA symmetrical output drive. It delivers high noise immunity and balanced t_PLH/t_PHL for reliable logic-level translation in space-constrained digital control circuits.

For engineers reviewing the MC74HC1G02DFT1G datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, validated SC-88A pin mapping, confirmed automotive-grade AEC-Q100 qualification status, and real-world substitution guidance for low-pin-count CMOS logic replacement.

Technical Context

The MC74HC1G02DFT1G implements a single 2-input NOR function using silicon-gate CMOS technology with buffered output stage, ensuring stable switching and high noise margin. Its internal design includes <100 FETs and supports rail-to-rail input/output operation across the full 2.0–6.0 V V_CC range.

It features symmetrical output impedance (I_OH = I_OL = 2 mA), balanced propagation delays (t_PLH ≈ t_PHL), and operates over −55 °C to +125 °C, meeting industrial and automotive temperature requirements per AEC-Q100 Class 0.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2.0 V to 6.0 V - Enables interoperability with 3.3 V and 5 V logic families without level shifters.
t_PD (Typ)	7 ns at V_CC = 5 V, C_L = 15 pF - Supports >100 MHz toggle rates in low-load timing-critical paths.
I_OH/I_OL	±2 mA - Sufficient to directly drive one 74HC input or small capacitive loads (<20 pF) without buffering.
Input Voltage Thresholds	V_IH = 3.15 V, V_IL = 1.35 V at V_CC = 4.5 V - Ensures robust noise margin (>1.8 V) under worst-case conditions.
Operating Temperature	−55 °C to +125 °C - Validated for under-hood automotive, industrial motor control, and extended-range instrumentation.
ESD Rating	HBM 2000 V, CDM 1000 V - Meets JEDEC JS-001 and JESD22-C101-F standards for handling and board assembly.

Pinout & Package

MC74HC1G02DFT1G uses the SC-88A (SOT-353) 5-pin surface-mount package (3.0 mm × 1.5 mm × 0.95 mm), optimized for high-density PCB layouts and automated placement.

Pin/Terminal	Circuit Role	Design Meaning
1	GND	Ground reference for all internal logic and output stages; must be low-impedance connection to minimize ground bounce.
2	B	Second logic input; accepts standard CMOS voltage levels (0 V / V_CC) and contributes to NOR truth table (Y = NOT(A OR B)).
3	A	Primary logic input; electrically identical to Pin 2 and fully interchangeable in circuit layout.
4	V_CC	Positive supply rail; decoupling capacitor (0.1 µF ceramic) required within 3 mm for stable high-speed operation.
5	Y	Inverted OR output; active-low logic level with rail-to-rail swing and symmetrical rise/fall times (t_TLH/t_THL ≤ 9 ns @ 5 V).

Key Features

Feature	Design Value
High-speed propagation	7 ns typical t_PD at 5 V enables use in clock distribution, enable gating, and fast state-machine control loops.
Symmetrical output drive	I_OH = I_OL = 2 mA ensures matched rise/fall times and eliminates duty-cycle distortion in feedback paths.
Wide supply range	2.0–6.0 V operation allows direct interface with legacy 5 V systems and modern 3.3 V/2.5 V microcontrollers.
Automotive qualification	AEC-Q100 Grade 0 certified with PPAP capability - qualified for safety-critical engine control, body electronics, and ADAS subsystems.
Pb-free & RoHS compliant	Halogen-free/BFR-free construction meets global environmental compliance mandates for automotive and industrial end equipment.

Equivalent & Alternatives

The following parts are listed as comparable options for similar single 2-input NOR gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G02DBVR	Lower V_CC min (1.65 V), faster t_PD (3.7 ns typ @ 3.3 V), but rated only to +85 °C industrial range.	Not qualified for automotive or extended-temperature industrial use; unsuitable for under-hood or outdoor deployments.	Select when operating exclusively at 1.8 V/3.3 V with tight timing budgets and no extended temperature requirement.
74AUP1G02GW,125	Ultra-low power (I_CC = 0.9 µA max), 1.8–3.6 V only, slower t_PD (11.5 ns typ @ 3.3 V), −40 °C to +125 °C.	Optimized for battery-powered IoT nodes; lacks 5 V tolerance and automotive qualification.	Prefer for energy-constrained edge devices where sub-µA quiescent current outweighs speed and voltage flexibility.

Compared with SN74LVC1G02DBVR and 74AUP1G02GW,125, the MC74HC1G02DFT1G uniquely combines 2.0–6.0 V operation, AEC-Q100 Grade 0 qualification, and 7 ns speed-making it the only choice for mixed-voltage automotive and industrial control where 5 V legacy compatibility and extreme temperature resilience are mandatory.

FAQ

What is the maximum operating frequency supported by the MC74HC1G02DFT1G?

The MC74HC1G02DFT1G does not specify a maximum clock frequency in its datasheet because it is a combinational logic gate-not a clocked device. However, with a typical propagation delay of 7 ns at 5 V and 15 pF load, it can reliably support signal toggle rates exceeding 100 MHz in low-capacitance paths. Actual usable frequency depends on system-level factors including trace capacitance, fan-out, and supply stability, all of which must be validated per application.

Is the MC74HC1G02DFT1G pin-compatible with other SC-88A logic gates like MC74HC1G00 or MC74HC1G04?

Yes, the MC74HC1G02DFT1G shares the identical SC-88A (SOT-353) 5-pin pinout with MC74HC1G00 (NAND), MC74HC1G04 (inverter), and other members of onsemi's 1G logic series. Pin 1 = GND, Pin 2 = Input B, Pin 3 = Input A, Pin 4 = V_CC, Pin 5 = Output Y - enabling direct footprint reuse across functionally distinct gates in layout-constrained designs.

Does the MC74HC1G02DFT1G support 5 V TTL input compatibility?

No, the MC74HC1G02DFT1G is a CMOS device with input thresholds referenced to V_CC (V_IH ≥ 0.7×V_CC, V_IL ≤ 0.3×V_CC). At V_CC = 5 V, V_IH = 3.5 V min, which falls short of standard TTL's 2.0 V V_IH threshold. Direct connection to 5 V TTL outputs may result in unreliable logic interpretation; a level-shifting buffer or resistor-based pull-up is required for interoperability.

What is the significance of the "DFT1G" suffix in MC74HC1G02DFT1G?

The "DFT1G" suffix identifies the specific packaging and marking configuration: "DF" denotes SC-88A (SOT-353) package, "T1" indicates tape-and-reel packaging with 3,000 units per reel, and "G" certifies Pb-free, RoHS-compliant construction. This distinguishes it from variants like MC74HC1G02DBVT1G (SC-74A package) and MC74HC1G02DFT2G (same package but 10,000-unit reel).

Can the MC74HC1G02DFT1G drive an LED directly?

No, the MC74HC1G02DFT1G is not intended for direct LED driving. Its absolute maximum output current is ±12.5 mA, but its guaranteed drive strength is only ±2 mA at VOH/VOL specifications. Driving even a low-current LED (e.g., 2 mA) risks violating VOL/VOH limits and degrading noise margins. A discrete transistor or dedicated LED driver IC should be used instead to ensure stable logic operation and LED brightness control.
