Product details
Overview
74ABT08D,118 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 serves as a high-speed combinational logic element in bus interface, address decoding, and control signal gating circuits.
For engineers reviewing the 74ABT08D,118 datasheet, 74ABT08D,118 pinout, 74ABT08D,118 application, or 74ABT08D,118 equivalent, this device is selected for TTL-compatible 5 V logic systems requiring low skew (<0.5 ns), robust ESD immunity (HBM >2000 V), latch-up resistance (>500 mA), and controlled backflow current during power sequencing.
Technical Context
The 74ABT08D implements four independent AND gates using BiCMOS technology, combining bipolar speed with CMOS input impedance. Each gate accepts two inputs (nA/nB) and delivers a single active-high output (nY), with truth table behavior strictly conforming to Boolean AND logic under all valid voltage and temperature conditions.
Its IOFF circuitry actively disables outputs when VCC = 0 V, limiting power-off leakage to ±100 μA while blocking reverse current flow-critical for hot-swap and multi-rail system designs. Propagation delay matching across outputs is guaranteed by design, with output skew ≤0.5 ns between any two switching outputs.
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 systems without level-shifting. |
| Propagation Delay | 1.0–4.0 ns (tPLH/tPHL) - Enables reliable timing in sub-5 ns clock domains and fast control-path logic. |
| Output Drive | IOL = 20 mA / IOH = –15 mA - Sinks or sources sufficient current to drive multiple TTL inputs or small capacitive loads. |
| IOFF Leakage | ±100 μA at VCC = 0 V - Prevents damaging backflow current during partial power-down or hot insertion. |
| ESD Rating | HBM >2000 V, CDM >1000 V - Meets industrial-grade ESD robustness requirements without external protection. |
| Operating Temp | –40 °C to +85 °C - Validated for use in extended-temperature industrial and communications equipment. |
| Input Thresholds | VIL ≤ 0.8 V, VIH ≥ 2.0 V - Guarantees unambiguous logic recognition across voltage and temperature extremes. |
Pinout & Package
74ABT08D,118 is housed in a plastic small outline package (SO14, SOT108-1) with 14 leads, 3.9 mm body width, and standard 1.27 mm lead pitch. The package is RoHS-compliant and rated for surface-mount reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | 1A, 2A, 3A, 4A | First input of each AND gate - referenced to GND; accepts TTL/CMOS logic levels. |
| 2, 5, 10, 13 | 1B, 2B, 3B, 4B | Second input of each AND gate - fully symmetrical with A inputs; no priority or enable function. |
| 3, 6, 8, 11 | 1Y, 2Y, 3Y, 4Y | Active-high AND output - drives downstream logic only when both corresponding A/B inputs are HIGH. |
| 7 | GND | Ground reference (0 V) - must be connected to system common; decoupling capacitor recommended near pin. |
| 14 | VCC | Positive supply rail - requires local 100 nF ceramic bypass capacitor to suppress switching noise. |
Key Features
| Feature | Design Value |
|---|---|
| BiCMOS process | Delivers 2.4 ns typical propagation delay with 20 mA output drive-superior speed-to-power ratio vs. pure CMOS. |
| IOFF partial power-down | Automatically disables outputs at VCC = 0 V, eliminating risk of backfeed into powered subsystems during sequencing. |
| TTL-level compatibility | Accepts standard TTL input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) without pull-ups or level translators. |
| Latch-up immunity | Exceeds 500 mA per JESD78B Class II Level A-ensures survivability under transient overvoltage or ground bounce. |
| Low output skew | ≤0.5 ns skew between any two outputs - critical for synchronous enable/gating of parallel data paths. |
Applications
| Bus Address Decoding | Control Signal Gating |
|---|---|
|
Use Scenario: Selecting memory or peripheral devices on a shared 8-bit or 16-bit data/address bus. IC Role / Device Role / Timing Role: AND gate array combines chip-select and address-line signals to generate precise decode windows. Use Value: Sub-4 ns propagation ensures setup/hold timing margins are maintained even at 25 MHz bus clocks. |
Use Scenario: Enabling/disabling clock or reset signals to subsystems based on mode or error status. IC Role / Device Role / Timing Role: Logic-level gating of active-HIGH control lines with zero added latency uncertainty. Use Value: Matched tPLH/tPHL and <0.5 ns skew prevent metastability or race conditions across gated outputs. |
| Power Sequencing Control | Digital Signal Conditioning |
|
Use Scenario: Coordinating startup/shutdown of multiple voltage rails in FPGA or DSP power domains. IC Role / Device Role / Timing Role: Combining power-good and enable signals to assert safe enable only when all preconditions are met. Use Value: IOFF functionality prevents back-current flow if one rail powers down before others-no external diodes needed. |
Use Scenario: Filtering spurious noise or glitches on digital control lines before they reach sensitive analog or RF sections. IC Role / Device Role / Timing Role: AND-ing a clean clock with a filtered enable signal to produce jitter-free gated output. Use Value: Low input capacitance (3 pF) and fast edge response minimize signal degradation in high-frequency paths. |
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 finer pitch. | Preferred for space-constrained PCBs where SO14 footprint is too large; thermal resistance slightly higher. | Select when board area is constrained and reflow profile supports TSSOP; same logic behavior and timing. |
| 74LVC08AD,118 | Lower-voltage LVC family: 1.65–3.6 V supply; 3.3 V compatible; lower drive (±24 mA), slower max delay (~5.5 ns). | Suitable for mixed-voltage 3.3 V systems; not interoperable with 5 V TTL without level translation. | Choose only for 3.3 V domains; incompatible with 5 V bus interfaces due to VIH/VIL mismatch and lack of IOFF. |
Compared with SN74ABT08DBR and 74LVC08AD,118, the 74ABT08D,118 uniquely balances 5 V TTL compatibility, sub-4 ns timing, and IOFF protection-making it the sole option for legacy 5 V industrial control systems requiring safe partial power-down.

FAQ
Does 74ABT08D,118 support mixed-voltage interfacing?
No. It operates exclusively from 4.5 V to 5.5 V and features TTL-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V). Interfacing with 3.3 V logic requires level translation; direct connection risks marginal or incorrect logic recognition.
Can 74ABT08D,118 be used in hot-swap applications?
Yes. Its IOFF circuitry actively disables outputs when VCC = 0 V, limiting backflow current to ±100 μA. This protects live backplanes and enables safe insertion/removal in powered systems without external isolation components.
What is the maximum capacitive load this device can drive reliably?
Per Nexperia's test conditions (Table 8), it is characterized up to 50 pF load with 500 Ω termination. Driving >50 pF may increase propagation delay and skew beyond spec; for heavier loads, add a buffer stage or reduce trace length/capacitance.
Is there a lead-free and halogen-free version of this part?
Yes. 74ABT08D,118 is manufactured in full compliance with RoHS Directive 2011/65/EU and Nexperia's Halogen-Free Policy (IEC 61249-2-21), with no brominated flame retardants or chlorine-based compounds in the mold compound or terminations.
