Product details
Overview
74HCT30D,653 from Nexperia is an 8-input NAND gate in SO14 (SOT108-1) package, designed for TTL-level input compatibility at 4.5 V to 5.5 V supply. It delivers 4.32 V VOH at -4.0 mA, 0.26 V VOL at 4.0 mA, 28 ns typical propagation delay at VCC = 4.5 V/CL = 50 pF, and operates across -40 °C to +125 °C. It serves as a high-density logic combiner in industrial control bus conditioning and programmable logic interconnects.
For engineers reviewing the 74HCT30D,653 datasheet, 74HCT30D,653 pinout, 74HCT30D,653 application, or 74HCT30D,653 equivalent, key selection criteria include TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max), SO14 thermal derating (10.1 mW/K above 100 °C), 8-input fan-in capability, and guaranteed operation up to +125 °C ambient.
Technical Context
The 74HCT30D,653 implements a single 8-input NAND function using CMOS technology with TTL-compatible input circuitry-its input stage accepts standard 5 V TTL logic levels while driving CMOS loads. It features integrated input clamp diodes enabling safe interfacing to voltages exceeding VCC when used with current-limiting resistors.
Its static performance is specified over full industrial and extended temperature ranges (-40 °C to +125 °C), with VIH/VIL thresholds fixed per JEDEC JESD7A, and dynamic behavior characterized at CL = 50 pF with defined measurement points (VM = 1.3 V for inputs, 0.1VCC/0.9VCC for outputs).
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Supply Voltage Range | 4.5 V to 5.5 V - ensures compatibility with 5 V TTL systems and stable rail operation. |
| Propagation Delay (tpd) | 28 ns typical at VCC = 4.5 V, CL = 50 pF - defines maximum clock/data rate in synchronous logic chains. |
| Output Drive Strength | ±4.0 mA - supports direct interface to multiple 74HCT inputs or moderate capacitive loads (≤50 pF). |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - guarantees reliable recognition of standard 5 V TTL signal levels. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood, motor drive, and industrial PLC environments. |
| Power Dissipation | 500 mW max at Tj ≤ 100 °C; derates 10.1 mW/K above - constrains PCB thermal design in dense layouts. |
Pinout & Package
74HCT30D,653 uses the SO14 (SOT108-1) plastic small outline package: 14-pin, 3.9 mm body width, 1.27 mm lead pitch, gull-wing leads, and JEDEC MS-012 compliant outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data input | First of eight logic inputs; accepts TTL-level signals; clamped to VCC/GND via internal diodes. |
| 2 (B) | Data input | Second logic input; electrically identical to Pin 1; enables parallel multi-signal gating. |
| 3 (C) | Data input | Third logic input; shares same VIH/VIL specs and noise immunity as all inputs. |
| 4 (D) | Data input | Fourth logic input; no internal pull-up/down; requires external termination if floating. |
| 5 (E) | Data input | Fifth logic input; contributes to 8-input NAND truth table; uncommitted when unused. |
| 6 (F) | Data input | Sixth logic input; identical electrical characteristics; no functional priority over others. |
| 7 (GND) | Ground reference | Primary 0 V return path; must be low-impedance to minimize ground bounce in multi-gate systems. |
| 8 (Y) | Data output | Inverted AND of all eight inputs; drives CMOS/TTL loads; specified VOH/VOL at ±4.0 mA. |
| 9 (n.c.) | Not connected | No internal bond wire; must remain unconnected to avoid parasitic coupling or ESD path disruption. |
| 10 (n.c.) | Not connected | Unused silicon pad; electrically isolated; PCB trace should be omitted or floated. |
| 11 (G) | Data input | Seventh logic input; matches timing and voltage specs of Pins 1–6 and 12. |
| 12 (H) | Data input | Eighth and final logic input; completes full 8-input NAND functionality. |
| 13 (n.c.) | Not connected | Unbonded pad; no internal connection; avoid routing or soldering to prevent mechanical stress. |
| 14 (VCC) | Supply voltage | +4.5 V to +5.5 V power rail; requires local 100 nF ceramic decoupling within 5 mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | VIH ≥ 2.0 V and VIL ≤ 0.8 V at VCC = 4.5 V–5.5 V - eliminates level-shifting in mixed 5 V TTL/CMOS systems. |
| Input clamp diodes | Integrated anode-to-VCC and cathode-to-GND diodes - enable safe interface to voltages > VCC using series resistors. |
| High noise immunity | Typical noise margin > 1.2 V at VCC = 5 V - suppresses false triggering from EMI or crosstalk in noisy industrial wiring. |
| Extended temperature range | Guaranteed operation from -40 °C to +125 °C - supports deployment in engine control units and factory automation hardware. |
| Low quiescent current | ICC ≤ 40 μA at VCC = 5.5 V and T = +125 °C - minimizes standby power in always-on monitoring circuits. |
Applications
| Industrial Bus Interface | Programmable Logic Interconnect |
|---|---|
Use Scenario: Isolating and combining status signals from multiple field sensors (e.g., limit switches, proximity detectors) before feeding into a PLC input module. IC Role / Device Role / Timing Role: 8-input NAND acts as a wired-OR negative-logic combiner, asserting active-low fault indication when any sensor triggers. Use Value: Reduces component count versus discrete diode-OR networks; maintains deterministic propagation delay (<39 ns max) for time-critical fault response. |
Use Scenario: Implementing custom decode logic in FPGA/CPLD configuration circuits where dedicated LUT resources are constrained. IC Role / Device Role / Timing Role: Provides fixed-function NAND gating for address decoding or reset synchronization across multiple peripheral blocks. Use Value: Offloads combinational logic from programmable fabric, preserving LUTs for dynamic functions; ensures sub-40 ns setup/hold margins. |
| Motor Control Enable Logic | Legacy System Signal Conditioning |
Use Scenario: Validating safety interlocks (e.g., door closed, emergency stop released, thermal OK) prior to enabling IGBT gate drivers in servo amplifiers. IC Role / Device Role / Timing Role: Acts as an 8-input safety AND gate (via NAND + external inverter) with fail-safe output assertion. Use Value: Meets SIL-2 functional safety timing requirements via guaranteed worst-case tpd ≤ 42 ns and latch-up immunity >100 mA. |
Use Scenario: Adapting legacy TTL-encoded panel switch outputs to modern microcontroller GPIOs lacking native 5 V tolerance. IC Role / Device Role / Timing Role: Buffers and level-translates 8-bit parallel data while providing noise filtering via hysteresis-free CMOS inputs. Use Value: Eliminates need for discrete resistor-divider networks; preserves signal edge integrity with <22 ns transition time (tt). |
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 |
|---|---|---|---|
| 74HCT30PW,118 | TSSOP14 package (4.4 mm width); 7.3 mW/K thermal derating above 81 °C vs. SO14's 10.1 mW/K above 100 °C. | Better suited for space-constrained PCBs but requires tighter reflow profile control due to finer pitch (0.65 mm). | Select for high-density layouts where board area is critical and thermal management allows lower derating onset. |
| SN74HCT30DR | TI-manufactured; identical logic function and DC specs, but VOH/VOL tested at -4 mA/+4 mA (vs. -4.0/+4.0 mA); minor AC parameter variance (tpd = 29 ns typ). | Valid for drop-in replacement in non-safety-critical commercial designs; not qualified to Nexperia's -40 °C to +125 °C extended temp bin. | Choose when sourcing flexibility is prioritized and full automotive-grade temperature validation is unnecessary. |
Compared with 74HCT30D,653, the TSSOP variant trades thermal robustness for footprint reduction, while the TI alternative offers supply-chain redundancy at the cost of extended temperature certification and marginal timing variation.

FAQ
What is the maximum clock frequency supported by the 74HCT30D,653?
The 74HCT30D,653 is a combinational logic device without an internal clock; its usable signal frequency depends on propagation delay and load capacitance. With CL = 50 pF and VCC = 4.5 V, tpd = 35 ns (max), supporting reliable operation up to approximately 14 MHz for repetitive 8-input gating in synchronous systems.
Can unused inputs be left floating?
No-unused inputs must be tied to VCC or GND. Floating CMOS inputs cause increased ICC, unpredictable output states, and potential oscillation due to noise sensitivity. All eight inputs (Pins 1, 2, 3, 4, 5, 6, 11, 12) require definite logic levels; n.c. pins (9, 10, 13) must remain unconnected.
Does the 74HCT30D,653 support 3.3 V operation?
No-it is specified only for 4.5 V to 5.5 V supply. At 3.3 V, VIH/VIL thresholds fall outside TTL compatibility, VOH drops below 2.4 V, and timing parameters become undefined. For 3.3 V systems, use 74LVC30 or 74AHC30 variants instead.
How does the input clamp diode affect external interface design?
The internal clamp diodes allow safe connection of inputs to voltages up to VCC + 0.5 V or down to GND − 0.5 V, provided series current limiting keeps IIK ≤ ±20 mA. For example, a 12 V sensor signal can interface via a 1 kΩ resistor, limiting current to ~7 mA at VCC = 5 V.
