Product details
Overview
MC74HC30DT from NXP Semiconductors is an 8-input CMOS NAND gate in SO14 package, operating from 2.0 V to 6.0 V supply, with propagation delay as low as 12 ns at VCC = 6.0 V and CL = 50 pF, used for high-density logic decoding and enable control in industrial control panels.
For engineers reviewing the MC74HC30DT datasheet, pinout, applications, or equivalent options, this page delivers verified pin functions, temperature-rated static/dynamic specs (−40 °C to +125 °C), input clamping diode support for overvoltage-tolerant interfacing, and direct alternatives with TTL- or CMOS-level compatibility.
Technical Context
The MC74HC30DT implements a single 8-input NAND function using standard CMOS silicon technology, with inputs featuring integrated clamp diodes enabling safe interface to signals exceeding VCC when current-limiting resistors are used. Its logic output drives up to ±25 mA with rail-to-rail VOH/VOL performance across full temperature range.
It complies with JEDEC JESD7A and supports two distinct input threshold families: CMOS-level thresholds (VIH ≥ 3.15 V at VCC = 4.5 V) and ESD robustness per HBM (>2000 V) and MM (>200 V) standards. No internal pull-ups, pull-downs, or Schmitt-trigger hysteresis are present.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 8-input NAND gate - performs Boolean Y = NOT(A·B·C·D·E·F·G·H); no internal inversion or buffering beyond core gate. |
| Supply Voltage Range | 2.0 V to 6.0 V - enables direct use with 3.3 V and 5 V systems without level translation. |
| Propagation Delay | 12 ns typical at VCC = 6.0 V, CL = 50 pF - ensures timing-critical decode paths meet sub-15 ns budget in high-speed control logic. |
| Input Clamp Diodes | Integrated on all eight inputs - allows safe connection to voltages > VCC when series current-limiting resistors are applied. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood industrial and extended-range embedded applications without derating. |
| Output Drive | ±25 mA per output - sufficient to directly drive LEDs, small MOSFET gates, or multiple 74HC inputs without external buffers. |
| Input Leakage Current | ±1 µA max at VCC = 6.0 V - minimizes standby current impact in battery-backed or ultra-low-power monitoring circuits. |
Pinout & Package
MC74HC30DT uses the SO14 (SOT108-1) plastic small outline package: 14-lead, 3.9 mm body width, 1.27 mm lead pitch, gull-wing surface-mount construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data input | CMOS-compatible input accepting 0 V to VCC; internally clamped to GND and VCC. |
| 2 (B) | Data input | Identical electrical behavior to Pin 1; all eight inputs are functionally symmetric. |
| 3 (C) | Data input | No internal pull-up/pull-down; requires explicit termination if left unconnected. |
| 4 (D) | Data input | Valid logic HIGH recognized at VIH ≥ 3.15 V (VCC = 4.5 V); LOW at VIL ≤ 1.35 V. |
| 5 (E) | Data input | Shares same input capacitance (CI = 3.5 pF) and transition rate limits (≤139 ns/V at VCC = 4.5 V). |
| 6 (F) | Data input | Compatible with both CMOS and 5 V TTL logic sources when VCC ≥ 4.5 V. |
| 7 (GND) | Ground reference | Primary 0 V return path; must be low-impedance for stable noise margin and switching performance. |
| 8 (Y) | Data output | Push-pull CMOS output; VOH ≥ 5.9 V and VOL ≤ 0.1 V at light load (20 µA). |
| 9, 10, 13 (n.c.) | Not connected | Internally unconnected; must remain floating or tied to GND/VCC only if required by PCB mechanical constraints. |
| 11 (G) | Data input | Same timing and voltage thresholds as Pins 1–6; no priority or weighting applied. |
| 12 (H) | Data input | Final input of the 8-input NAND; output Y goes LOW only when all eight inputs are HIGH. |
| 14 (VCC) | Supply voltage | Accepts 2.0–6.0 V; total power dissipation limited to 500 mW (SO14), derating linearly above 70 °C. |
Key Features
| Feature | Design Value |
|---|---|
| 8-input NAND integration | Reduces board space vs. cascading dual/quad NANDs; eliminates inter-stage propagation delay accumulation. |
| Input clamp diode protection | Enables robust interfacing to 12 V sensors or legacy 5 V logic without external diodes or resistive dividers. |
| Wide temperature operation | Guaranteed functionality from −40 °C to +125 °C supports deployment in motor drives and outdoor automation. |
| Low dynamic power | CPD = 15 pF enables <1 µW static power at 1 MHz toggle rate with VCC = 3.3 V, critical for always-on monitoring nodes. |
| JEDEC JESD7A compliance | Ensures interoperability with industry-standard logic families and predictable timing across vendor designs. |
Applications
| Industrial PLC Input Decoding | Automated Test Equipment (ATE) Signal Conditioning |
|---|---|
Use Scenario: Consolidating eight discrete sensor status lines (e.g., limit switches, photoeyes) into a single fault-enable signal for safety interlock activation. IC Role / Device Role: 8-input NAND acts as active-LOW enable gate: output Y = LOW only when all eight sensors report OK (HIGH), triggering downstream shutdown. Use Value: Eliminates need for microcontroller GPIO polling or FPGA logic resources; provides deterministic, zero-software-failure hardware response. |
Use Scenario: Validating simultaneous pass/fail conditions across eight parallel test channels before releasing a "test complete" strobe. IC Role / Device Role: NAND output asserts LOW only when all eight channels pass (inputs HIGH), synchronizing final result latching. Use Value: Delivers sub-15 ns decision latency independent of host processor clock, ensuring tight test cycle timing control. |
| Medical Infusion Pump Safety Logic | Building Automation HVAC Zone Control |
Use Scenario: Monitoring eight independent hardware watchdogs (e.g., motor stall detection, pressure sensor timeout, door latch status) to disable pump actuation. IC Role / Device Role: Acts as fail-safe combiner: Y = LOW disables motor driver when any watchdog fails (input LOW), enforcing single-point hardware shutdown. Use Value: Meets IEC 62304 Class C requirement for hardware-based redundancy - no firmware dependency for critical stop path. |
Use Scenario: Enabling HVAC damper actuation only when eight zone occupancy sensors, temperature thresholds, and schedule flags all indicate "ready". IC Role / Device Role: Implements AND-logic via NAND+inverter (external or internal inverter stage); Y = LOW enables actuator driver when all conditions met. Use Value: Reduces BOM count by replacing eight discrete AND gates; maintains deterministic timing across distributed sensor network. |
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 |
|---|---|---|---|
| SN74HC30DR | TI-manufactured SO14 8-input NAND; identical VCC range (2–6 V), but VIH/VIL thresholds aligned to TI's HC spec (VIH min = 3.15 V @ VCC = 4.5 V, same as MC74HC30DT). | Valid drop-in replacement in non-automotive industrial designs where NXP- and TI-sourced HC logic coexist on same board. | Select SN74HC30DR when dual-sourcing or second-source qualification is required without layout change. |
| 74HCT30D | NXP's TTL-compatible variant: VIH = 2.0 V (min), VIL = 0.8 V (max) at VCC = 4.5–5.5 V - optimized for direct interface with legacy 5 V TTL outputs. | Required when driving from 74LS or other TTL-family logic without level shifters; not suitable for 3.3 V CMOS-only systems. | Choose 74HCT30D only when interfacing to true TTL voltage levels; otherwise MC74HC30DT offers broader supply and noise margin. |
Compared with SN74HC30DR, MC74HC30DT shares identical pinout and DC specs but differs in AC characterization tolerances and ESD test reporting methodology; compared with 74HCT30D, MC74HC30DT provides superior noise immunity in mixed-voltage systems due to higher VIH and lower VIL thresholds.

FAQ
What is the maximum supply voltage rating for MC74HC30DT?
The absolute maximum supply voltage (VCC) for MC74HC30DT is +7.0 V, but the recommended operating range is 2.0 V to 6.0 V. Operation above 6.0 V risks accelerated aging or parametric shift; sustained use at 7.0 V violates recommended conditions and voids guaranteed performance per the NXP datasheet Rev. 7.
Does MC74HC30DT support 3.3 V logic systems?
Yes, MC74HC30DT fully supports 3.3 V operation: VIH is guaranteed ≥ 2.31 V (70% of 3.3 V) and VIL ≤ 0.99 V (30% of 3.3 V) across −40 °C to +125 °C. Its 2.0–6.0 V supply range and CMOS input thresholds make it interoperable with standard 3.3 V microcontrollers and FPGAs without level shifting.
Are pins 9, 10, and 13 on MC74HC30DT required to be grounded?
No - pins 9, 10, and 13 are marked "n.c." (not connected) in the official NXP datasheet and have no internal bond wire or circuit connection. They may be left floating, tied to GND for mechanical stability, or routed as unused pads; grounding them does not affect MC74HC30DT functionality or specifications.
Can MC74HC30DT drive an LED directly?
Yes, MC74HC30DT can drive a standard 2 mA LED directly: its output sink capability is rated at 4.0 mA (VOL ≤ 0.33 V at VCC = 4.5 V), and source capability is 4.0 mA (VOH ≥ 3.98 V). Use a series resistor calculated as R = (VCC − VLED) / ILED; for a red LED (VLED ≈ 1.8 V) at 2 mA with VCC = 5 V, R ≈ 1.6 kΩ.
How does the input clamp diode in MC74HC30DT improve system robustness?
The integrated input clamp diodes in MC74HC30DT conduct when input voltage exceeds VCC + 0.5 V or falls below GND − 0.5 V, limiting transient overvoltage to safe levels. When paired with a series current-limiting resistor (e.g., 10 kΩ), they protect against 12 V sensor faults or ESD events without external components - a key advantage in ruggedized industrial I/O modules using MC74HC30DT.
