Product details
Overview
74ABT02PW,112 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 delays with 50 pF load, used in high-speed digital control, bus arbitration, and address decoding circuits.
For engineers reviewing the 74ABT02PW,112 datasheet, 74ABT02PW,112 pinout, 74ABT02PW,112 application, or 74ABT02PW,112 equivalent, key selection considerations include guaranteed 20 mA IOL drive strength, ±1.0 µA input leakage over –40°C to +85°C, output skew ≤0.5 ns, and TSSOP-14 package compatibility with automated SMT assembly.
Technical Context
The 74ABT02PW,112 implements four independent 2-input NOR gates using ABT (Advanced BiCMOS Technology) logic, supporting TTL-compatible input thresholds (VIL ≤ 0.8 V, VIH ≥ 2.0 V) and rail-to-rail CMOS-level outputs. It features active-low enable behavior inherent to standard NOR function and operates across industrial temperature range without derating.
Designed for 5 V systems, the device meets AC characteristics with tPLH/tPHL ≤ 4.4/3.4 ns max over full temperature and voltage range, and maintains low ICC quiescent current (≤50 µA) while enabling fast edge rates (input transition rate ≤5 ns/V) for noise-immune signal routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - ensures compatibility with regulated 5 V logic rails and tolerance to supply ripple |
| tPLH / tPHL | 2.4 ns / 1.8 ns typical at CL = 50 pF - enables sub-5 ns gate-level timing in synchronous control paths |
| IOL / IOH | 20 mA / –15 mA - drives standard TTL loads and fan-out of ≥20 LS-TTL inputs |
| VOL / VOH | 0.35 V / 2.5 V min at IOL = 20 mA - guarantees robust noise margins in mixed-logic interfacing |
| Input Capacitance | 3 pF - minimizes loading on preceding drivers and preserves signal integrity in high-frequency buses |
| Operating Temp | –40°C to +85°C - supports deployment in industrial control panels and automotive under-hood ECUs |
| Output Skew | ≤0.5 ns - ensures deterministic timing alignment across all four NOR outputs for parallel logic operations |
Pinout & Package
74ABT02PW,112 is housed in a 14-lead TSSOP (Thin Shrink Small Outline Package), 4.4 mm body width, lead pitch 0.65 mm, compliant with JEDEC MO-153. Pin 7 is GND; Pin 14 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | Y0–Y3 | NOR gate outputs - active-low logic level; each capable of sinking 20 mA or sourcing 15 mA |
| 2, 3, 5, 6, 8, 9, 11, 12 | A0–A3, B0–B3 | Independent input pairs per gate - TTL-compatible thresholds allow direct connection to 74LS/74ALS outputs |
| 7 | GND | Logic ground reference - must be low-impedance path to minimize switching noise coupling |
| 14 | VCC | Positive supply - requires local 100 nF ceramic decoupling adjacent to pin for stable high-speed operation |
Key Features
| Feature | Design Value |
|---|---|
| ABT BiCMOS Process | Combines bipolar speed and CMOS low power - achieves 2.4 ns propagation delay with only 50 µA ICC quiescent current |
| TTL-Compatible Inputs | VIL ≤ 0.8 V and VIH ≥ 2.0 V - eliminates need for level-shifting when interfacing legacy 74LS logic |
| High Sink Current | 20 mA per output - directly drives LEDs, small relays, or multiple downstream logic inputs without buffers |
| Low Input Capacitance | 3 pF - reduces capacitive loading on clock or data lines, preserving rise/fall times in dense PCB layouts |
| Industrial Temperature Range | –40°C to +85°C - qualified for use in programmable logic controllers and motor drive control boards |
Applications
| Bus Arbitration Logic | Address Decoding |
|---|---|
Use Scenario: Resolving contention among multiple masters on a shared data bus in microcontroller-based systems. IC Role / Device Role / Timing Role: NOR gate implements priority encoder enable logic and bus grant signaling with sub-5 ns decision latency. Use Value: Ensures deterministic bus ownership handoff with <0.5 ns inter-output skew, preventing metastability in multi-master arbitration. | Use Scenario: Generating chip-select signals for memory-mapped peripherals in 8-bit and 16-bit embedded systems. IC Role / Device Role / Timing Role: Four independent NOR gates decode upper address bits to activate specific peripheral address windows. Use Value: Delivers 2.4 ns typical propagation delay to minimize address decode overhead and maximize system throughput. |
| Digital Control Sequencing | Power-On Reset Coordination |
Use Scenario: Implementing state-dependent enable/disable logic for DC-DC converter modules and FPGA configuration sequencers. IC Role / Device Role / Timing Role: NOR gates generate synchronized enable pulses based on status flags and clock edges in real-time control loops. Use Value: 20 mA sink capability allows direct driving of MOSFET gate drivers or optocoupler inputs without external transistors. | Use Scenario: Combining reset sources (power monitor, watchdog timeout, manual button) into a single clean system reset assertion. IC Role / Device Role / Timing Role: NOR gate performs active-low OR function to assert reset when any input goes low during power-up sequencing. Use Value: Low VOL (0.35 V typ.) ensures reliable reset deassertion across voltage tolerances and temperature extremes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR gate logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ABT02DBR | Same ABT process, identical AC/DC specs, SOIC-14 package (SOT108-1) instead of TSSOP-14 | Requires PCB footprint change; suitable where board space permits larger SOIC body width (3.9 mm vs. 4.4 mm) | Select when existing design uses SOIC-14 land pattern or requires higher thermal mass for manual rework |
| 74LVC02PW,118 | Lower VCC range (1.65–3.6 V), 3.3 V optimized; tPLH/tPHL ~3.5 ns typical; 24 mA IOL | Not 5 V tolerant; incompatible with legacy 5 V systems unless level-shifted | Choose only for new 3.3 V designs prioritizing lower power and smaller die size over 5 V interoperability |
Compared with SN74ABT02DBR and 74LVC02PW,118, the 74ABT02PW,112 uniquely balances 5 V TTL compatibility, sub-5 ns speed, and TSSOP-14 footprint-making it optimal for space-constrained industrial control upgrades requiring drop-in replacement of legacy DIP/SO NOR gates.

FAQ
What is the maximum operating supply voltage for the 74ABT02PW,112?
The 74ABT02PW,112 has an absolute maximum VCC rating of +7.0 V, but its recommended operating range is strictly 4.5 V to 5.5 V. Operation outside this range may cause excessive ICC, degraded timing, or accelerated wear-out. The 74ABT02PW,112 must be powered within 4.5–5.5 V to guarantee all AC/DC specifications including tPLH ≤ 4.4 ns and VOL ≤ 0.5 V.
Does the 74ABT02PW,112 support hot insertion or live insertion into a powered backplane?
No, the 74ABT02PW,112 does not support hot insertion. Its absolute maximum ratings specify VI ≤ –1.2 V and VOUT ≤ –0.5 V during power-off conditions, and IOFF leakage can reach ±100 µA when VCC = 0 V. Applying signals before VCC stabilization risks latch-up or permanent damage. The 74ABT02PW,112 must be powered and stabilized prior to asserting any input or output signals.
Can the 74ABT02PW,112 drive a 50 pF load at 10 MHz without waveform degradation?
Yes-the 74ABT02PW,112 is characterized with CL = 50 pF and tR/tF = 2.5 ns, and its typical tPLH/tPHL of 2.4/1.8 ns supports clean 10 MHz square-wave output. At that frequency, edge fidelity is preserved due to low output impedance and 20 mA sink capability. The 74ABT02PW,112 maintains monotonic transitions and <0.5 ns skew across all outputs under these conditions.
Is the 74ABT02PW,112 pin-compatible with older 74LS02 or 74HC02 devices?
The 74ABT02PW,112 shares identical pinout (14-pin TSSOP) and logic function with 74LS02 and 74HC02, but differs electrically: it requires 4.5–5.5 V supply (vs. 5 V ±0.25 V for LS, 2–6 V for HC), delivers higher drive (20 mA vs. 8 mA LS, 4 mA HC), and exhibits faster propagation (2.4 ns vs. 15 ns LS, 7 ns HC). The 74ABT02PW,112 is not a direct drop-in replacement without verifying supply and loading conditions.
What is the thermal resistance (θJA) of the 74ABT02PW,112 in its TSSOP-14 package?
The 74ABT02PW,112 TSSOP-14 package has a typical junction-to-ambient thermal resistance (θJA) of 150°C/W under standard JEDEC JESD51-2 PCB conditions (single-layer copper, 1 in² pad). This value assumes no internal power dissipation exceeding 100 mW; actual θJA improves with added copper pour or thermal vias. The 74ABT02PW,112 remains within safe junction limits (<150°C) up to +85°C ambient when dissipating ≤67 mW.
