Product details
Overview
74ABT02DB,118 from Nexperia is a quad 2-input NOR gate logic IC operating at 4.5–5.5 V supply, delivering 2.4 ns typical tPLH and 1.8 ns typical tPHL propagation delay with 50 pF load, used in high-speed digital control, bus arbitration, and address decoding circuits.
For engineers reviewing the 74ABT02DB,118 datasheet, 74ABT02DB,118 pinout, 74ABT02DB,118 application, or 74ABT02DB,118 equivalent, key selection criteria include guaranteed AC performance over –40°C to +85°C, low input capacitance (3 pF), output drive capability (20 mA sink / –15 mA source), and SSOP-14 package compatibility with space-constrained PCB layouts.
Technical Context
The 74ABT02DB,118 implements four independent 2-input NOR gates using ABT (Advanced BiCMOS Technology) logic, optimized for TTL-compatible input thresholds (VIL ≤ 0.8 V, VIH ≥ 2.0 V) and 5 V operation. It supports full industrial temperature range operation without derating.
All outputs are push-pull with symmetrical rise/fall characteristics and tightly controlled output-to-output skew (≤0.5 ns), enabling reliable timing in synchronous logic interfaces and state machine implementations where gate delay matching matters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - Ensures robust operation across noisy 5 V rails and brown-out conditions. |
| tPLH / tPHL | 2.4 ns / 1.8 ns (typical, CL = 50 pF) - Enables sub-3 ns gate-level timing in high-speed combinatorial logic paths. |
| IOL / IOH | 20 mA sink / –15 mA source - Drives standard TTL loads and multiple 74-series inputs without buffering. |
| CIN | 3 pF - Minimizes capacitive loading on preceding drivers and preserves signal edge integrity. |
| Operating Temp | –40°C to +85°C - Qualified for industrial and automotive under-hood control modules. |
| ICC (quiescent) | 50 µA max - Supports low-static-power system design even with multiple gates enabled. |
Pinout & Package
74ABT02DB,118 is housed in a 14-lead plastic shrink small outline package (SSOP), body width 5.3 mm, compliant with SOT337-1 drawing. Pin pitch is 0.65 mm, footprint compatible with fine-pitch surface-mount assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | Y0–Y3 | Active-low NOR outputs - Drive downstream logic or enable/disable functions with inverted polarity. |
| 2, 3, 5, 6, 8, 9, 11, 12 | A0–A3, B0–B3 | Independent NOR inputs - Accept standard TTL/CMOS logic levels; no internal pull-ups or pull-downs. |
| 7 | GND | Ground reference - Must be connected to system 0 V plane with low-inductance path for noise immunity. |
| 14 | VCC | Positive supply - Requires local 100 nF ceramic decoupling capacitor placed within 3 mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| ABT technology | Combines bipolar speed and CMOS low power - Achieves 2 ns propagation with <50 µA quiescent current. |
| TTL-compatible inputs | VIL ≤ 0.8 V, VIH ≥ 2.0 V - Interoperates directly with legacy 74LS and microcontroller GPIO without level shifters. |
| Output skew control | ≤0.5 ns (tOSLH/tOSHL) - Enables deterministic timing in multi-gate fanout or parallel decode paths. |
| Wide operating temperature | –40°C to +85°C - Validated for use in industrial PLC I/O modules and motor drive control boards. |
Applications
| Industrial Bus Arbitration | Microcontroller Address Decoding |
|---|---|
Use Scenario: Resolving contention among multiple masters on a shared parallel data bus in programmable logic controllers. IC Role / Device Role / Timing Role: NOR gate implements priority encoder logic to assert bus grant signals with sub-3 ns decision latency. Use Value: Tight propagation delay matching ensures deterministic arbitration sequence across all four channels without added timing margin. | Use Scenario: Generating chip-select signals for memory-mapped peripherals (e.g., ADC, DAC, UART) in 8-bit MCU systems. IC Role / Device Role / Timing Role: Quad NOR combines address bits to produce active-low peripheral enables synchronized to clock edges. Use Value: Low input capacitance (3 pF) prevents loading of MCU address lines, preserving setup/hold timing margins. |
| Digital Power Sequencing Control | FPGA Configuration Logic |
Use Scenario: Enabling DC-DC converter rails in strict power-up order based on supervisor status and reset signals. IC Role / Device Role / Timing Role: NOR gates implement combinational logic for AND-NOR derived enable chains with fail-safe default-off behavior.

IC Role / Device Role / Timing Role: Provides glitch-free inversion and gating of configuration control signals before reaching FPGA I/O banks. Use Value: Output drive strength (20 mA sink) safely handles FPGA input leakage and trace capacitance up to 10 cm. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ABT02DBR | Same ABT process, identical AC/DC specs, TI-branded SSOP-14 package (SOT337-1 equivalent). | No functional difference; validated for same industrial temp range and drive requirements. | Select when sourcing from TI-authorized channels or requiring dual-sourcing with identical parametric behavior. |
| 74LVC02PW,118 | Lower VCC range (1.65–3.6 V), 3.3 V only; 4.2 ns max tPD at 3.3 V; 24 mA IOL. | Not suitable for 5 V systems; requires level translation if interfacing with 5 V MCU or legacy peripherals. | Choose only for new 3.3 V designs prioritizing ultra-low static power (<1 µA ICC) and smaller TSSOP package. |
Compared with SN74ABT02DBR and 74LVC02PW,118, the 74ABT02DB,118 uniquely delivers 5 V TTL-compatible operation with sub-3 ns speed and industrial temperature support in SSOP-14 - making it the sole drop-in solution for legacy 5 V control logic upgrades requiring no redesign.

FAQ
What is the maximum recommended operating voltage for 74ABT02DB,118?
The 74ABT02DB,118 has a maximum recommended operating supply voltage of 5.5 V per its datasheet. Absolute maximum rating is 7.0 V, but sustained operation above 5.5 V risks exceeding specified AC/DC parameters and may compromise long-term reliability. Always maintain VCC between 4.5 V and 5.5 V for guaranteed 74ABT02DB,118 performance across temperature.
Does 74ABT02DB,118 support mixed-voltage interfacing with 3.3 V logic?
The 74ABT02DB,118 accepts 3.3 V logic-high inputs reliably (VIH min = 2.0 V), but its outputs swing to ~3.5 V (VOH min = 2.5 V at –15 mA) under 5 V supply - insufficient for driving 3.3 V CMOS inputs requiring >3.0 V VIH. For bidirectional 3.3 V/5 V interfacing, external level-shifting or a 74LVC02-based solution is required. The 74ABT02DB,118 itself is strictly a 5 V logic device.
Is 74ABT02DB,118 pin-compatible with other 74ABT02 variants like DIP or SO packages?
Yes - all 74ABT02 variants (DIP, SO, SSOP, TSSOP) share identical pinout per the Philips/Nexperia logic diagram and pin description table. The 74ABT02DB,118 uses SOT337-1 (SSOP-14), matching pin-for-pin with 74ABT02N (DIP), 74ABT02D (SO), and 74ABT02PW (TSSOP). No PCB layout change is needed when migrating to 74ABT02DB,118 from any other 74ABT02 package variant.
What is the thermal resistance (θJA) of the 74ABT02DB,118 in its SSOP package?
The 74ABT02DB,118 in SOT337-1 (SSOP-14) has a typical junction-to-ambient thermal resistance (θJA) of 120°C/W under JEDEC-standard 2-layer board conditions. This value assumes minimal copper pour; adding thermal vias and 1 oz copper planes reduces θJA significantly. With 74ABT02DB,118's low ICC (≤50 µA), self-heating is negligible - junction temperature remains within limits even at +85°C ambient.
Can 74ABT02DB,118 be used in life support or safety-critical medical equipment?
No - the 74ABT02DB,118 is not qualified for life support applications. Nexperia's documentation explicitly states that its products, including the 74ABT02DB,118, are not designed for use where malfunction could reasonably cause personal injury. Medical devices requiring IEC 61508 or ISO 13485 compliance must use components with formal safety certification; the 74ABT02DB,118 does not meet those requirements.
