Product details
Overview
74ABT08D/AUJ from Nexperia is a quad 2-input AND gate logic IC in SO14 package, operating from 4.5 V to 5.5 V supply, with propagation delays as low as 1.0 ns (tPLH/tPHL), IOFF-enabled partial power-down protection, and guaranteed operation from –40 °C to +85 °C. It interfaces directly with TTL-level systems and delivers 20 mA sink current per output for robust bus driving in digital control circuits.
For engineers reviewing the 74ABT08D/AUJ datasheet, 74ABT08D/AUJ pinout, 74ABT08D/AUJ application, or 74ABT08D/AUJ equivalent, this page provides verified pin functions, real-world timing behavior, IOFF implementation details, static/dynamic electrical specs, and validated alternatives for industrial control, legacy TTL interfacing, and hot-swap-capable logic subsystems.
Technical Context
The 74ABT08D/AUJ implements four independent AND gates using BiCMOS technology, combining bipolar speed with CMOS input impedance and low power consumption. Its IOFF circuitry actively disables outputs when VCC = 0 V, preventing backflow current during partial power-down sequences.
Each gate exhibits matched propagation delays (tPLH/tPHL ≤ 4.0 ns over temperature), sub-0.5 ns output skew, and TTL-compatible input thresholds (VIL ≤ 0.8 V, VIH ≥ 2.0 V), enabling seamless integration into mixed-voltage 5 V logic systems without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures compatibility with standard 5 V TTL and CMOS rails; tolerates ±10 % regulation variation. |
| Propagation Delay | tPLH/tPHL ≤ 4.0 ns at VCC = 5.0 V - Enables reliable operation in high-speed control paths up to ~250 MHz toggle rate. |
| Output Drive | IOL = 20 mA / IOH = –15 mA - Sinks sufficient current to drive multiple TTL inputs or small capacitive loads (≤50 pF). |
| IOFF Leakage | ±100 μA at VCC = 0 V - Limits backfeed current during hot-insertion or partial shutdown, protecting upstream sources. |
| Operating Temperature | –40 °C to +85 °C - Qualified for industrial environments without derating or external thermal management. |
| ESD Robustness | HBM > 2000 V, CDM > 1000 V - Survives handling and board assembly without special ESD controls beyond standard practices. |
Pinout & Package
74ABT08D/AUJ is housed in a plastic small outline package (SO14, SOT108-1) with 14 leads and 3.9 mm body width. Pin 1 is marked by a notch or bevel; the package is RoHS-compliant and lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | 1A, 2A, 3A, 4A | Independent data inputs for each AND gate - accept TTL/CMOS logic levels; high-impedance CMOS input structure. |
| 2, 5, 10, 13 | 1B, 2B, 3B, 4B | Second data inputs per gate - electrically identical to A inputs; no internal differentiation or priority. |
| 3, 6, 8, 11 | 1Y, 2Y, 3Y, 4Y | Active-high AND outputs - driven to VOL ≤ 0.5 V at 20 mA sink; VOH ≥ 2.5 V at –15 mA source. |
| 7 | GND | Ground reference - must be connected to system 0 V plane; serves as return path for all I/O and supply currents. |
| 14 | VCC | Positive supply - powers internal BiCMOS circuitry; IOFF activation occurs when VCC = 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| IOFF Partial Power-down | Disables outputs and limits leakage to ±100 μA when VCC = 0 V - enables safe insertion/removal in live backplanes. |
| TTL-Compatible Inputs | VIL ≤ 0.8 V and VIH ≥ 2.0 V - eliminates need for external level shifters when interfacing with legacy 5 V TTL devices. |
| BiCMOS Output Drive | 20 mA sink / 15 mA source capability - drives heavier capacitive loads and multiple fanouts than standard CMOS equivalents. |
| Low Propagation Skew | tsk(o) ≤ 0.5 ns - ensures simultaneous switching across all four gates, critical for synchronous enable/control bus applications. |
| Latch-up Immunity | Exceeds 500 mA per JESD78B Class II Level A - prevents destructive latch-up under transient overvoltage or ESD stress. |
Applications
| Industrial Control Logic | Legacy System Bus Interface |
|---|---|
Use Scenario: Enabling/disabling signal paths in programmable logic controllers (PLCs) where modules may be powered down independently. IC Role / Device Role / Timing Role: Quad AND gate acting as gated enable for address/data latches and peripheral select lines. Use Value: IOFF prevents backfeed from active modules into unpowered sections, eliminating risk of unintended register writes or bus contention. |
Use Scenario: Interfacing modern microcontrollers with legacy TTL-based instrumentation buses (e.g., GPIB auxiliary control lines). IC Role / Device Role / Timing Role: Level-adapting AND gate translating 3.3 V GPIO outputs to full 5 V TTL swing while preserving timing integrity. Use Value: Direct TTL compatibility and 1.0 ns min propagation delay ensure setup/hold timing margins are maintained without added latency. |
| Hot-Swappable Backplane Logic | Digital Power Sequencing |
Use Scenario: Controlling power-good signals and reset distribution in modular telecom line cards that support field-replaceable units. IC Role / Device Role / Timing Role: AND gate synchronizing multiple power-rail OK signals before releasing system reset. Use Value: IOFF guarantees no false resets or glitches during card insertion/removal, as unpowered 74ABT08D/AUJ presents high-impedance inputs and disabled outputs. |
Use Scenario: Implementing interlocked enable logic for multi-rail DC/DC converters in FPGA-based embedded systems. IC Role / Device Role / Timing Role: Gate enforcing strict sequencing order (e.g., VCCAUX must be stable before VCCINT enable). Use Value: Sub-4 ns max propagation delay ensures tight coordination between rail monitors and enable drivers, minimizing window for undervoltage faults. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ABT08DBR | Same ABT family, TSSOP14 (SOT402-1) package; identical electrical specs but 4.4 mm body width and 0.65 mm pitch. | Requires PCB layout change due to different footprint and thermal pad absence; better suited for high-density routing. | Select when board space is constrained and reflow profile supports fine-pitch TSSOP. |
| 74LVC08AD | Lower voltage operation (1.65–3.6 V), higher max tPLH (5.2 ns), no IOFF; LVC logic family with 24 mA drive. | Not suitable for 5 V systems or partial power-down; requires level translation if interfacing with TTL. | Choose only for 3.3 V-only designs where IOFF is unnecessary and cost is prioritized over 5 V compatibility. |
Compared with SN74ABT08DBR, the 74ABT08D/AUJ offers identical logic performance but simplifies layout with SO14's wider pitch and proven manufacturability; versus 74LVC08AD, it delivers essential 5 V tolerance and IOFF-critical for industrial hot-swap and mixed-voltage interoperability.

FAQ
What is the maximum allowable supply voltage for the 74ABT08D/AUJ?
The absolute maximum supply voltage (VCC) for the 74ABT08D/AUJ is +7.0 V, but the recommended operating range is strictly 4.5 V to 5.5 V. Operating outside this range risks violating static/dynamic specifications and may accelerate parametric drift or reduce long-term reliability. The 74ABT08D/AUJ is not rated for sustained operation above 5.5 V, even briefly.
Does the 74ABT08D/AUJ support hot-swap applications?
Yes-the 74ABT08D/AUJ includes dedicated IOFF circuitry that disables outputs and limits power-off leakage to ±100 μA when VCC = 0 V. This prevents damaging backflow current during live insertion or removal in backplane or modular systems. The 74ABT08D/AUJ is explicitly characterized for partial power-down use cases per its datasheet Section 1.
Can the 74ABT08D/AUJ drive standard TTL loads directly?
Yes-the 74ABT08D/AUJ features TTL-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) and delivers 20 mA sink current per output, matching standard TTL fanout requirements. Its VOH ≥ 2.5 V at –15 mA and VOL ≤ 0.5 V at 20 mA ensure noise margins exceed TTL specifications, allowing direct connection without level shifters or buffers.
What is the typical propagation delay of the 74ABT08D/AUJ at 25 °C?
At 25 °C and VCC = 5.0 V, the 74ABT08D/AUJ exhibits typical propagation delays of tPLH = 2.4 ns and tPHL = 1.9 ns. These values reflect average performance across production lots and are measured under defined test conditions (CL = 50 pF, RL = 500 Ω). The 74ABT08D/AUJ datasheet guarantees worst-case delays of ≤ 3.4 ns (tPLH) and ≤ 2.8 ns (tPHL) at 25 °C.
Is the 74ABT08D/AUJ qualified for automotive applications?
No-the 74ABT08D/AUJ is not automotive-qualified. Nexperia explicitly states in its legal disclaimers that unless a product data sheet expressly declares automotive qualification, the device is unsuitable for automotive use. The 74ABT08D/AUJ is specified for industrial temperature range (–40 °C to +85 °C) and lacks AEC-Q100 stress testing, extended lifetime validation, or automotive-specific failure mode analysis required for vehicle applications.
