Product details

Overview

MC74HC1G00DTT1G from onsemi is a single 2-input NAND 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), symmetrical output drive (I_OH/I_OL = ±2 mA), and operates across −55°C to +125°C - used in logic-level translation, enable control, and signal inversion in space-constrained industrial sensor interfaces.

For engineers reviewing the MC74HC1G00DTT1G datasheet, pinout, applications, or equivalent options, key selection criteria include propagation delay matching, rail-to-rail input compatibility (V_IN = 0–V_CC), low quiescent current (I_CC ≤ 1 µA max), and AEC-Q100 qualification for automotive-adjacent designs.

Technical Context

The MC74HC1G00DTT1G implements a single 2-input NAND function using buffered CMOS stages to ensure high noise immunity and stable output transitions. Its internal architecture provides balanced t_PLH/t_PHL delays and matched output impedance (|I_OH| = |I_OL| = 2 mA at V_CC = 4.5–6.0 V), enabling predictable timing in combinational logic chains.

It supports wide supply range (2.0–6.0 V), operates over extended temperature (−55°C to +125°C), and meets AEC-Q100 Grade 1 requirements when ordered with −Q suffix - though MC74HC1G00DTT1G itself is commercial-grade (non−Q) with MSL Level 1 moisture sensitivity.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2.0 V to 6.0 V - enables direct interface 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 - ensures sub-10 ns timing in high-speed control paths.
I_OH/I_OL	±2 mA at V_CC = 4.5–6.0 V - sufficient to drive one 74HC input or small capacitive loads (< 20 pF).
V_IL/V_IH	0.5 V / 1.5 V (min) at V_CC = 2.0 V - guarantees reliable TTL- and CMOS-compatible input thresholds.
I_CC (Max)	1 µA at T_A = 25°C - supports ultra-low-power standby states in battery-backed systems.
Operating Temp	−55°C to +125°C - validated for under-hood, industrial PLC, and outdoor equipment environments.

Pinout & Package

MC74HC1G00DTT1G uses the SC-88A (SOT-353) 5-pin surface-mount package: 1.2 mm × 2.0 mm × 0.95 mm body height, lead pitch 0.95 mm, Pb-free and RoHS compliant.

Pin/Terminal	Circuit Role	Design Meaning
1	GND	Ground reference for all inputs/outputs; must be low-impedance connection to minimize noise coupling.
2	B	Second logic input; accepts 0–V_CC voltage levels with guaranteed switching at V_IL/V_IH thresholds.
3	A	Primary logic input; electrically identical to Pin 2; both inputs share same DC and AC characteristics.
4	V_CC	Positive supply rail; decoupling capacitor (0.1 µF ceramic) required within 3 mm of this pin.
5	Y	NAND output (Y = A·B); actively driven high/low; no internal pull-up/down; requires external load termination if open-drain use is intended.

Key Features

Feature	Design Value
High-speed propagation	t_PD = 7 ns typical at 5 V - reduces combinatorial delay in feedback loops and state-machine decode paths.
Symmetrical output drive	I_OH = I_OL = 2 mA - eliminates duty-cycle distortion when driving clocked logic or RC networks.
Balanced transition times	t_TLH/t_THL ≤ 10 ns at 5 V - maintains clean edge integrity for downstream sampling circuits.
Wide supply tolerance	Operates from 2.0 V to 6.0 V - allows reuse across mixed-voltage subsystems (e.g., 3.3 V MCU + 5 V analog front-end).

Applications

Industrial Sensor Interface	Automotive Body Control
Use Scenario: Signal conditioning for dual-threshold proximity sensors where two independent detection signals must be ANDed before triggering an interrupt. IC Role / Device Role / Timing Role: Single NAND gate performing active-low enable logic; placed directly at sensor output stage to reduce routing stubs and EMI susceptibility. Use Value: Eliminates need for larger 74HC00 quad-NAND, saving 60% board area while maintaining <10 ns timing margin for 1 MHz polling cycles.	Use Scenario: Door lock actuator enable gating, where ignition status (A) and door-closed signal (B) jointly determine Y = LOCK_ENABLE. IC Role / Device Role / Timing Role: Combinational logic element in safety-critical path; operates at 3.3 V with full −40°C to +105°C validation per AEC-Q100 Grade 2 (via −Q variants). Use Value: Provides deterministic fail-safe behavior: output remains HIGH only when both inputs are HIGH - prevents unintended actuation during power-up transients.
Portable Medical Device	IoT Edge Node
Use Scenario: Power-on self-test (POST) sequencer in handheld glucose meter, verifying sensor bias and ADC readiness before measurement. IC Role / Device Role / Timing Role: NAND-based handshake generator; output Y clocks next-stage latch only after both calibration flags settle. Use Value: Ultra-low I_CC (≤1 µA) extends battery life in sleep mode; SC-88A footprint fits tight 8 mm × 8 mm PCB real estate.	Use Scenario: Wake-up event combiner in LPWAN node, merging motion-detect (A) and ambient-light-threshold (B) signals to trigger BLE broadcast. IC Role / Device Role / Timing Role: Low-power logic gate interfacing directly with GPIOs of nRF52840; operates at 1.8 V minimum supply. Use Value: Guaranteed VIH/VIL margins at 1.8 V (VIH ≥ 1.35 V, VIL ≤ 0.45 V) prevent metastability during brown-out conditions.

Equivalent & Alternatives

The following parts are listed as comparable options for similar single 2-input NAND gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G00DBVR	Lower V_CC min (1.65 V), higher speed (t_PD = 3.7 ns typ), but narrower temp range (−40°C to +125°C).	Preferred for 1.8 V systems; not qualified for −55°C operation or automotive PPAP.	Select when operating below 2.0 V or requiring <4 ns delay; verify layout compatibility (SOT-23-5 vs SC-88A pinout differs).
74AUP1G00GW,125	Ultra-low power (I_CC = 0.9 µA max), wider V_CC (0.8–3.6 V), but slower (t_PD = 11.5 ns typ at 3.3 V).	Optimized for sub-1 V IoT microcontrollers; lacks AEC-Q100 support and 6 V tolerance.	Choose for battery-powered wearables needing <1 µA sleep current; avoid in 5 V domains or high-temp industrial use.

Compared with SN74LVC1G00DBVR and 74AUP1G00GW,125, the MC74HC1G00DTT1G uniquely supports full −55°C to +125°C operation at 2–6 V with AEC-Q100-qualified variants available - making it the only option among the three validated for extended-temperature industrial control and automotive-adjacent sensor fusion.

FAQ

What is the maximum operating supply voltage for MC74HC1G00DTT1G?

The MC74HC1G00DTT1G supports a maximum DC supply voltage of +6.5 V, with recommended operation up to 6.0 V. Exceeding 6.5 V risks permanent damage per Absolute Maximum Ratings. For reliable long-term use, maintain V_CC within 2.0–6.0 V per Recommended Operating Conditions - especially critical when interfacing with 5 V microcontrollers or legacy peripherals.

Does MC74HC1G00DTT1G have built-in ESD protection?

Yes, MC74HC1G00DTT1G features on-die ESD protection rated at 2000 V HBM and 1000 V CDM per JESD22 standards. This meets typical handling requirements for automated SMT assembly, though proper grounding and ionized airflow remain essential during board handling. The device does not include system-level TVS clamping - external protection is advised for connectors exposed to user interaction.

Is MC74HC1G00DTT1G pin-compatible with other SC-88A logic gates?

No - MC74HC1G00DTT1G has a fixed pinout (GND-B-A-V_CC-Y) specific to its NAND function. Other SC-88A logic devices (e.g., inverters, OR gates) use different pin assignments. Always verify pin mapping against the exact part's datasheet; mechanical compatibility does not imply electrical or functional interchangeability.

Can MC74HC1G00DTT1G drive a 50 pF load at 2.0 V supply?

Yes, MC74HC1G00DTT1G is characterized for 50 pF loads at V_CC = 2.0 V, with t_PLH/t_PHL ≤ 100 ns (max) per AC Electrical Characteristics. Output swing remains rail-to-rail (V_OL ≤ 0.1 V, V_OH ≥ 1.9 V), ensuring noise margin >0.4 V - sufficient for driving multiple 74HC inputs or short PCB traces in low-voltage IoT nodes.

What is the thermal resistance (θ_JA) of MC74HC1G00DTT1G in its SC-88A package?

The MC74HC1G00DTT1G in SC-88A package has a junction-to-ambient thermal resistance (θ_JA) of 377°C/W when mounted on a standard FR4 board with minimum pad spacing and 20-ounce copper trace per JESD51-7. This value assumes no thermal vias or heatsinking - derate power dissipation accordingly in enclosed or high-ambient-temperature environments.
