Product details
Overview
74HCT00DB,112 from Nexperia is a quad 2-input NAND gate IC with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 5.0 V), 4.5–5.5 V supply range, propagation delay of 12 ns (typ) at VCC = 4.5 V and CL = 50 pF, and SO14 (SOT337-1) package. It operates across –40 °C to +125 °C and serves as a fundamental logic building block in digital control, address decoding, and enable gating circuits.
For engineers reviewing the 74HCT00DB,112 datasheet, 74HCT00DB,112 pinout, 74HCT00DB,112 application, or 74HCT00DB,112 equivalent, this page delivers verified functional identity, validated pin mapping for SOT337-1, confirmed TTL-level interface behavior, and real-world use context - all derived from Nexperia's official Rev. 11 product data sheet (April 2025).
Technical Context
The 74HCT00DB,112 implements four independent 2-input NAND gates using CMOS technology with TTL-compatible input circuitry, enabling direct interfacing with legacy 5 V TTL logic families without level translation. Its inputs include clamp diodes, allowing safe operation with input voltages exceeding VCC when current-limited.
It features rail-to-rail output swing (VOH ≥ 3.7 V, VOL ≤ 0.4 V at IO = ±4 mA), low static ICC (≤40 μA at VCC = 6.0 V), and robust ESD protection (HBM > 2000 V, CDM > 1000 V). The device is specified for industrial and extended temperature ranges and complies with JEDEC JESD7A and JESD8C standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NAND gate - provides four independent Boolean NOT-AND operations per package. |
| Supply Voltage Range | 4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL systems and stable operation under nominal rail variation. |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - matches TTL logic levels, eliminating need for external level shifters. |
| Propagation Delay | 12 ns typ (VCC = 4.5 V, CL = 50 pF) - supports reliable timing in medium-speed digital control and sequencing applications. |
| Output Drive | ±4 mA (VOH/VOL guaranteed) - sufficient to drive multiple 74-series TTL inputs or small capacitive loads directly. |
| Operating Temperature | –40 °C to +125 °C - qualified for industrial, automotive under-hood adjacent, and high-reliability embedded environments. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets IEC/JS-001/JS-002 Class 2/C3, reducing handling and board-level ESD risk. |
Pinout & Package
74HCT00DB,112 is housed in a plastic shrink small outline package (SSOP14) with 14 leads, body width 5.3 mm, and pitch 0.65 mm (SOT337-1). This compact surface-mount package supports higher board density than standard SO14 while maintaining compatibility with automated assembly processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | 1A, 2A, 3A, 4A | First input of each NAND gate - accepts TTL-level HIGH/LOW signals; includes internal clamp diode to VCC/GND. |
| 2, 5, 10, 13 | 1B, 2B, 3B, 4B | Second input of each NAND gate - electrically identical to A inputs; enables full combinational logic flexibility. |
| 3, 6, 8, 11 | 1Y, 2Y, 3Y, 4Y | Active-low NAND output - sinks or sources up to ±4 mA; VOH ≥ 3.7 V and VOL ≤ 0.4 V under rated load. |
| 7 | GND | Ground reference (0 V) - must be connected to system common; serves as return path for all input/output currents. |
| 14 | VCC | Positive supply (4.5–5.5 V) - powers internal CMOS structure; decoupling capacitor (100 nF) recommended near pin. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | VIH = 2.0 V min / VIL = 0.8 V max at VCC = 5.0 V - enables plug-in replacement of 74LS00 in legacy 5 V systems. |
| Wide supply tolerance | Operates from 4.5 V to 5.5 V - accommodates ±5 % rail variation without functional degradation or timing shift. |
| Clamp diode protection | Internal input diodes to VCC and GND - permits safe interface to voltages beyond VCC when series current limiting is applied. |
| High noise immunity | Typical noise margin > 0.8 V (HIGH) and > 0.6 V (LOW) at VCC = 5.0 V - resists coupling-induced glitches in mixed-signal PCB layouts. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive parasitic SCR activation during transient overvoltage events. |
Applications
| Industrial Control Logic | Microcontroller Peripheral Interface |
|---|---|
|
Use Scenario: Discrete sensor status aggregation and fault condition masking in PLC I/O modules. IC Role / Device Role / Timing Role: NAND gate used as active-low enable combiner for multiple interrupt sources feeding an MCU's NMI line. Use Value: Eliminates need for external pull-up resistors or discrete transistors by providing rail-rail, current-sinking outputs compatible with 5 V microcontroller inputs. |
Use Scenario: Address decoding for memory-mapped peripherals on 8-bit microcontrollers (e.g., ATmega328P, PIC16F877A). IC Role / Device Role / Timing Role: Forms part of a 3-to-8 decoder network to select SPI flash, EEPROM, or GPIO expander CS lines. Use Value: 12 ns propagation delay ensures setup/hold timing margins are maintained at 8 MHz bus clock rates without added wait states. |
| Power Sequencing Enable Gate | Legacy Bus Signal Conditioning |
|
Use Scenario: Generating synchronized power-on reset enable for multi-rail DC/DC converter controllers. IC Role / Device Role / Timing Role: Combines PWR_OK signals from three regulators via NAND logic to assert a single "system ready" signal. Use Value: TTL input thresholds ensure correct interpretation of open-drain regulator status outputs without external biasing networks. |
Use Scenario: Glue logic between legacy 5 V TTL buses (e.g., ISA, parallel printer port) and modern FPGA I/O banks. IC Role / Device Role / Timing Role: Inverts and combines handshake signals (STROBE, ACK) to generate bidirectional flow control pulses. Use Value: SO14/SOT337-1 footprint allows drop-in placement on existing through-hole or mixed-technology PCBs with minimal layout change. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT00D,118 | Same logic function and electrical specs, but in SO14 (SOT108-1) package with 3.9 mm body width and 1.27 mm pitch. | Requires PCB footprint revision; less dense than SSOP but more widely supported in legacy reflow profiles. | Select when standard SO14 tooling, inspection, or hand-soldering capability is prioritized over board space. |
| SN74HCT00DR | TI variant with identical VIH/VIL, same 4.5–5.5 V range, but slightly higher max ICC (100 μA vs. 40 μA) and different ESD rating (HBM > 4000 V). | Valid for TI-centric BOMs; pinout and timing match, but long-term availability tied to TI's lifecycle policy. | Choose for dual-sourcing in TI-dominated designs where second-source assurance outweighs minor power trade-off. |
Compared with 74HCT00DB,112, the 74HCT00D,118 offers mechanical compatibility with broader assembly infrastructure, while SN74HCT00DR provides enhanced ESD robustness and vendor diversification - both retain identical logic behavior and interface compatibility for seamless integration into existing 5 V TTL systems.

FAQ
Is 74HCT00DB,112 pin-compatible with 74LS00?
Yes - it uses identical pinout (14-pin SSOP) and TTL-compatible input thresholds, enabling direct replacement in most 74LS00 applications. Output drive strength (±4 mA) matches LS-series capability, and propagation delay (12 ns) is comparable to 74LS00's 15 ns, ensuring timing integrity without redesign.
Can 74HCT00DB,112 operate at 3.3 V supply?
No - the 74HCT00DB,112 is specified only for 4.5 V to 5.5 V operation. At 3.3 V, input thresholds become undefined and output voltage levels fall outside TTL-compatibility requirements. For 3.3 V systems, use 74HC00 variants or 74LVC00 with appropriate VCCIO configuration.
What is the thermal resistance (RθJA) of the SOT337-1 package?
The SOT337-1 (SSOP14) package has a typical RθJA of 125 K/W under standard JEDEC JESD51-2 PCB conditions (2-layer board, 1 in² copper). This value supports continuous operation up to +125 °C ambient when total power dissipation remains below 4 mW, consistent with its 250 mW absolute maximum rating derated above 121 °C.
Does 74HCT00DB,112 require external pull-up resistors on outputs?
No - its totem-pole CMOS outputs actively drive both HIGH and LOW states. Pull-ups are unnecessary unless implementing wired-AND configurations (e.g., open-collector emulation), which this device does not support. Outputs meet TTL VOH/VOL specifications directly into standard 5 V logic inputs.
