Product details
Overview
74HCT30D,652 from Nexperia is an 8-input TTL-compatible NAND gate in SO14 package, operating from 4.5 V to 5.5 V supply, delivering 4.32 V VOH at -4 mA and 0.26 V VOL at 4 mA over -40 °C to +125 °C, used for high-density combinational logic in industrial control backplanes and digital interface arbitration.
For engineers reviewing the 74HCT30D,652 datasheet, 74HCT30D,652 pinout, 74HCT30D,652 application, or 74HCT30D,652 equivalent, key selection criteria include TTL-level input compatibility, SO14 thermal derating (10.1 mW/K above 100 °C), 28 ns max propagation delay at 4.5 V, and 8-input single-gate logic consolidation capability.
Technical Context
This device implements a single 8-input NAND function with Schmitt-trigger–free inputs and standard CMOS output structure. It uses silicon-gate CMOS technology with TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 5 V), enabling direct interfacing with legacy 5 V TTL logic families without level-shifting.
Inputs feature integrated clamp diodes allowing safe operation with input voltages exceeding VCC when current-limited, and the output stage supports ±4 mA DC drive into resistive loads while maintaining rail-to-rail swing under specified conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | 8-input NAND: outputs LOW only when all eight inputs are HIGH |
| Supply Voltage Range | 4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL systems |
| Propagation Delay | 28 ns max at VCC = 4.5 V, CL = 50 pF - determines maximum clock/data rate in synchronous logic |
| Output Drive | ±4.0 mA - sufficient to drive multiple 74-series inputs or small capacitive loads |
| Operating Temperature | -40 °C to +125 °C - qualified for extended industrial and under-hood applications |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - matches TTL logic levels for seamless integration |
| Power Dissipation | 40 μA ICC max at VCC = 5.5 V - enables low-static-power system design |
Pinout & Package
74HCT30D,652 is housed in SO14 (SOT108-1) plastic small outline package: 14-pin, 3.9 mm body width, 1.27 mm lead pitch, JEDEC MS-012 compliant, with 10.1 mW/K thermal derating above 100 °C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data input | First of eight logic inputs; accepts TTL-level signals |
| 2 (B) | Data input | Second logic input; electrically identical to Pin 1 |
| 3 (C) | Data input | Third logic input; no internal pull-up/pull-down |
| 4 (D) | Data input | Fourth logic input; compatible with 5 V TTL fan-out |
| 5 (E) | Data input | Fifth logic input; shares same VIH/VIL specs as all inputs |
| 6 (F) | Data input | Sixth logic input; clamped to VCC/GND for overvoltage tolerance |
| 7 (GND) | Ground reference | 0 V return path for all internal circuitry and I/O |
| 8 (Y) | Data output | Inverted AND of all eight inputs; drives standard CMOS loads |
| 9,10,13 (n.c.) | Not connected | No internal connection; must be left floating or grounded per layout rules |
| 11 (G) | Data input | Seventh logic input; identical electrical behavior to Pins 1–6 |
| 12 (H) | Data input | Eighth and final logic input; completes 8-input NAND function |
| 14 (VCC) | Supply voltage | +4.5 V to +5.5 V power rail; bypass capacitor required near pin |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | VIH ≥ 2.0 V and VIL ≤ 0.8 V at 5 V supply enables plug-in replacement of 74LS30 |
| Wide temperature range | Specified from -40 °C to +125 °C supports deployment in harsh industrial environments |
| Input clamp diodes | Allow safe interface to signals up to VCC + 0.5 V when series current limiting is applied |
| Low dynamic power | CPD = 15 pF enables predictable switching power calculation: PD = CPD × VCC² × fi × N |
| ESD robustness | HBM > 2000 V and CDM > 1000 V reduce handling sensitivity and board-level failure risk |
Applications
| Industrial PLC Backplane Logic | Digital Interface Arbitration |
|---|---|
Use Scenario: Consolidating enable signals from eight field I/O modules before routing to a central controller. IC Role / Device Role / Timing Role: Single-gate 8-input NAND performs wired-OR inversion to generate a unified fault latch signal. Use Value: Reduces PCB footprint versus discrete 2-input NAND cascades and eliminates timing skew across parallel paths. | Use Scenario: Resolving bus contention between four microcontroller peripherals sharing a common SPI bus segment. IC Role / Device Role / Timing Role: Acts as a priority encoder input combiner, asserting chip-select only when all request lines are inactive. Use Value: Ensures deterministic bus release timing with sub-30 ns propagation, avoiding metastability in shared resource access. |
| Legacy System TTL Integration | Power Sequencing Validation |
Use Scenario: Interfacing modern FPGA I/O banks to legacy 5 V TTL peripheral cards in test equipment racks. IC Role / Device Role / Timing Role: Level-translating logic gate that accepts 5 V TTL inputs and drives 5 V CMOS-compatible outputs. Use Value: Eliminates need for dedicated level shifters while preserving noise margin and fan-out capability. | Use Scenario: Monitoring eight independent DC/DC converter OK signals to assert a global POWER_GOOD line. IC Role / Device Role / Timing Role: Active-low enable aggregator: output goes LOW only when all eight converters are stable. Use Value: Provides fail-safe startup sequencing with single-point monitoring and no software dependency. |
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 | Better board density but lower thermal mass; requires tighter reflow profile | Select for space-constrained designs where SO14 footprint is prohibitive |
| SN74HCT30DR | Texas Instruments part; VIH = 2.0 V min, VIL = 0.8 V max, but tpd = 30 ns max at 5 V | Slightly slower propagation; different ESD rating (HBM > 4000 V) | Choose when higher HBM immunity is required and 2 ns delay penalty is acceptable |
Compared with 74HCT30D,652, the TSSOP variant offers smaller area but reduced thermal headroom, while the TI alternative trades 2 ns speed for enhanced ESD protection-both require layout and thermal validation before substitution.

FAQ
Is 74HCT30D,652 pin-compatible with 74LS30?
Yes, 74HCT30D,652 is pin-compatible with 74LS30 in SO14 package and provides identical pinout (A–H inputs, Y output, VCC, GND, and n.c. pins). Its TTL-compatible input thresholds and 5 V supply operation allow direct replacement without circuit modification, though output drive strength and propagation delay differ slightly.
Can 74HCT30D,652 operate at 3.3 V supply?
No. The 74HCT30D,652 is specified only for 4.5 V to 5.5 V operation. At 3.3 V, input thresholds (VIH ≥ 2.0 V) become marginal relative to VCC, risking unreliable HIGH detection. For 3.3 V systems, use 74HC30D or 74LVC30APW instead, which are designed for lower-voltage logic families.
What is the meaning of 'n.c.' pins 9, 10, and 13?
Pins 9, 10, and 13 are not internally connected and serve no electrical function. They must be left unconnected (floating) or tied to GND per PCB layout best practices to minimize parasitic coupling. Do not route signals or apply voltage to these pins, as they have no internal bonding wire or die connection.
Does 74HCT30D,652 support hot-swap or live-insertion?
No. 74HCT30D,652 lacks hot-swap protection circuitry such as power-on reset, I²C-style slew-rate control, or back-drive prevention. Applying VCC before inputs stabilize-or vice versa-may cause latch-up or excessive current through input clamps. Always power VCC first and ensure inputs remain within -0.5 V to VCC + 0.5 V during insertion.
