Product details
Overview
MC74HC30ADTR2G from onsemi is an 8-input NAND gate logic IC in TSSOP-14 package, operating across 2–6 V supply, delivering 10 LSTTL load drive capability and propagation delay as low as 30 ns at 6 V. It interfaces directly with CMOS, NMOS, and TTL families and is used in digital control logic, address decoding, and enable gating in industrial microcontroller peripherals.
For engineers reviewing the MC74HC30ADTR2G datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage range (2–6 V), input compatibility with LSTTL (with pullups), guaranteed propagation delay (≤45 ns at 125°C), and Pb-free TSSOP-14 packaging for space-constrained PCB layouts.
Technical Context
This high-performance silicon-gate CMOS device implements a single 8-input NAND function (Y = A·B·C·D·E·F·G·H) with inputs compatible with standard CMOS outputs and LSTTL outputs when pullup resistors are applied. Its logic diagram and pinout confirm dedicated VCC (Pin 14), GND (Pin 7), and three no-connect terminals (Pins 9, 10, 13).
The device supports full-rail input and output voltage operation (0 to VCC), exhibits low input current (±0.1 µA max at 6 V), and maintains stable switching performance across –55°C to +125°C ambient temperature. Input clamp current is ±20 mA, and output drive is rated for ±4.0 mA at 4.5 V and ±5.2 mA at 6.0 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 8-input NAND gate (Y = A·B·C·D·E·F·G·H) |
| Supply Voltage Range | 2.0 V to 6.0 V - enables direct interface with 3.3 V and 5 V systems without level shifters |
| Propagation Delay (tPLH/tPHL) | 30 ns max at VCC = 6.0 V, TA = 25°C - ensures timing compliance in medium-speed digital control paths |
| Output Drive | ±4.0 mA at 4.5 V - sufficient to drive 10 LSTTL loads or multiple CMOS inputs |
| Input Leakage Current | ±0.1 µA max at VCC = 6.0 V - minimizes static power draw and prevents unintended logic transitions |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 11, 12 | Inputs A–H | Eight independent logic inputs; all must be tied to valid logic level (VCC or GND) if unused |
| 7 | GND | Ground reference for all internal circuitry and I/O; requires low-impedance PCB connection |
| 8 | Output Y | Active-low NAND output; sinks or sources up to ±5.2 mA depending on VCC and load |
| 9, 10, 13 | No Connection | Internally unconnected; must remain floating - no external bias or routing permitted |
| 14 | VCC | Positive supply rail; bypassing with 0.1 µF ceramic capacitor near pin is recommended |
Key Features
| Feature | Design Value |
|---|---|
| CMOS + TTL interoperability | Direct interface with CMOS/NMOS/TTL without level translation; LSTTL-compatible with pullups |
| Wide supply range | 2–6 V operation supports mixed-voltage system integration (e.g., 3.3 V MCU controlling 5 V peripherals) |
| High noise immunity | Typical noise margin >40% of VCC due to CMOS threshold design - resists EMI in noisy industrial settings |
| Pb-free & RoHS compliance | Meets global environmental regulations; compatible with lead-free reflow profiles (260°C peak) |
| Low quiescent current | ICC ≤ 2 µA at 25°C - enables use in battery-backed or always-on monitoring circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC30PW | TSSOP-14, same logic function and DC specs; propagation delay 32 ns @ 6 V (vs. 30 ns for MC74HC30ADTR2G) | TI part uses different thermal resistance (140°C/W vs. 150°C/W) and slightly higher ICC (4 µA vs. 2 µA) | Preferred where TI supply chain alignment or legacy schematic reuse is required; not pin-identical due to marking and minor timing variance |
| 74HC30D,118 | SO-14 package (not TSSOP); identical AC/DC specs but larger footprint and higher thermal resistance (116°C/W) | Suitable for prototyping or through-hole-to-SMT transition; lacks space-saving advantage of TSSOP | Select when board real estate allows SOIC or when existing SOIC footprints must be retained without layout change |
Compared with SN74HC30PW and 74HC30D,118, the MC74HC30ADTR2G offers the lowest propagation delay at 6 V, tightest input leakage spec, and optimized thermal performance in TSSOP-14 - making it preferred for high-density, thermally constrained industrial control designs.

FAQ
What is the maximum operating temperature for MC74HC30ADTR2G?
The MC74HC30ADTR2G is specified for continuous operation from –55°C to +125°C junction temperature. Its guaranteed performance across this full range - including propagation delay and output drive - makes it suitable for under-hood automotive and industrial motor-drive applications where ambient temperatures exceed 85°C.
Does MC74HC30ADTR2G require external pull-up resistors on inputs?
MC74HC30ADTR2G inputs are compatible with standard CMOS outputs without pull-ups. However, when interfacing with LSTTL outputs, external pull-up resistors are required to ensure valid high-level input voltage (VIH ≥ 3.15 V at VCC = 4.5 V). The datasheet explicitly states this requirement for LSTTL compatibility.
Can unused inputs on MC74HC30ADTR2G be left floating?
No. Per the MC74HC30ADTR2G datasheet (Note 3 in Recommended Operating Conditions), all unused inputs must be tied to a valid logic level - either VCC or GND - to prevent increased supply current, oscillation, or undefined output states. Floating inputs risk excessive power consumption and logic instability.
What is the meaning of "DT" in MC74HC30ADTR2G?
The "DT" suffix in MC74HC30ADTR2G denotes the TSSOP-14 package (Case 948G), per onsemi's ordering nomenclature. "R2G" indicates tape-and-reel packaging (2500 units per reel) and Pb-free construction. This distinguishes it from the SOIC-14 version (MC74HC30ADR2G, "D" suffix).
Is MC74HC30ADTR2G pin-compatible with older LS30 devices?
Yes - the MC74HC30ADTR2G is explicitly stated in its datasheet to be identical in pinout to the 74LS30. This allows drop-in replacement in legacy TTL-based designs, provided supply voltage is adjusted to 2–6 V and input drive capability is verified, since HC logic draws significantly less input current than LS.
