Product details
Overview
74ABT08DB,118 from Nexperia is a quad 2-input AND gate logic IC in SO14 (SOT108-1) package, operating at 4.5–5.5 V supply, with 1.0–4.0 ns propagation delay, IOFF-enabled partial power-down protection, and -40 °C to +85 °C industrial temperature range. It performs Boolean conjunction across four independent channels in digital control, address decoding, and bus gating applications.
For engineers reviewing the 74ABT08DB,118 datasheet, 74ABT08DB,118 pinout, 74ABT08DB,118 application, or 74ABT08DB,118 equivalent, this page delivers verified functional identity, validated SO14 pin mapping, confirmed BiCMOS timing specs, and real-world interface constraints for TTL-compatible system integration.
Technical Context
The 74ABT08DB,118 implements four independent AND gates using BiCMOS process technology, combining bipolar speed with CMOS low-power characteristics. Each gate accepts two TTL-level inputs and drives a single output with ±20 mA sink/source capability under 5 V operation.
Its IOFF circuitry actively disables outputs when VCC = 0 V, limiting backflow current to ±100 μA - critical for hot-swap and multi-rail partial power-down systems. Propagation delays are tightly controlled: tPLH/tPHL ≤ 4.0/3.0 ns over full temperature range, with output skew ≤ 0.5 ns between any two gates.
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 mixed-voltage logic interfaces |
| Propagation Delay | 1.0–4.0 ns (tPLH/tPHL) - enables reliable operation in sub-100 MHz synchronous digital systems |
| Output Drive | ±20 mA (IOL/IOH) - directly drives multiple TTL loads without external buffers |
| IOFF Leakage | ±100 μA at VCC = 0 V - prevents damaging back-current during power sequencing |
| Operating Temperature | -40 °C to +85 °C - certified for industrial-grade embedded control and instrumentation |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - withstands handling and board-level electrostatic events |
| Input Thresholds | VIL ≤ 0.8 V, VIH ≥ 2.0 V - guarantees robust noise margin against TTL logic levels |
Pinout & Package
74ABT08DB,118 is housed in a plastic small outline package (SO14), SOT108-1 variant: 14-pin, 3.9 mm body width, 1.27 mm lead pitch, gull-wing leads, JEDEC MS-012 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | 1A, 2A, 3A, 4A | First input per AND gate - accepts TTL-compatible logic signals |
| 2, 5, 10, 13 | 1B, 2B, 3B, 4B | Second input per AND gate - enables dual-input Boolean conjunction |
| 3, 6, 8, 11 | 1Y, 2Y, 3Y, 4Y | Respective gate outputs - actively driven HIGH/LOW with rail-to-rail swing |
| 7 | GND | Digital ground reference - must be low-impedance for stable noise margin |
| 14 | VCC | Positive supply - powers all four gates and enables IOFF control logic |
Key Features
| Feature | Design Value |
|---|---|
| BiCMOS architecture | Combines <1.9 ns typical tPHL with <50 μA ICC quiescent current at 5.5 V |
| IOFF partial power-down | Outputs enter high-Z state at VCC = 0 V, blocking backflow up to ±100 μA |
| TTL-level interface | Direct connection to legacy 74LS/74F families without level-shifting |
| Latch-up immunity | Exceeds 500 mA per JESD78B Class II - survives transient bus faults |
| Industrial temperature range | Guaranteed functionality from -40 °C to +85 °C ambient |
Applications
| Industrial PLC I/O Expansion | Legacy Bus Address Decoding |
|---|---|
Use Scenario: Isolating and enabling discrete sensor inputs in modular PLC backplanes where power domains may be sequenced independently. IC Role / Device Role / Timing Role: Quad AND gate performing enable-gated signal pass-through with IOFF preventing cross-domain leakage during module hot-swap. Use Value: Eliminates need for external isolation diodes or power-switching FETs by enforcing output disable at VCC = 0 V. |
Use Scenario: Generating chip-select signals for memory-mapped peripherals on 8-bit microcontroller buses (e.g., Z80, 8051). IC Role / Device Role / Timing Role: Combining address bits and control strobes to generate precise decode windows with sub-4 ns timing resolution. Use Value: Enables deterministic 5 V bus timing with <0.5 ns inter-output skew, avoiding address decode glitches. |
| Test Equipment Signal Gating | Digital Audio Clock Domain Control |

IC Role / Device Role / Timing Role: AND-ing test enable and data valid signals to gate stimulus pulses with minimal added jitter. Use Value: Delivers <4.0 ns max propagation delay and <0.5 ns skew - preserves edge integrity in high-speed digital test vectors. |
Use Scenario: Controlling clock distribution to audio DAC/ADC subsystems based on sample rate configuration bits. IC Role / Device Role / Timing Role: Performing logic-level gating of master clock signals before fanout buffers in mixed-signal SoM designs. Use Value: Provides TTL-compatible input thresholds and 20 mA drive to reliably trigger clock buffer enable pins. |
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 | TSSOP14 (SOT402-1) package; identical electrical specs but 4.4 mm body width and 0.65 mm pitch | Better PCB space efficiency; requires finer-pitch reflow profile | Select for high-density layouts where thermal mass and footprint are constrained |
| 74LVC08AD,118 | 3.3 V only (1.65–3.6 V); lower drive (±24 mA), no IOFF, higher input capacitance (4 pF) | Not suitable for 5 V TTL interfacing or partial power-down systems | Choose only for pure 3.3 V LVTTL environments with no hot-swap requirements |
Compared with SN74ABT08DBR and 74LVC08AD,118, the 74ABT08DB,118 uniquely supports 5 V operation with guaranteed IOFF behavior - making it irreplaceable in legacy industrial systems requiring both TTL compatibility and safe power sequencing.

FAQ
Does 74ABT08DB,118 support mixed-voltage operation between 3.3 V and 5 V logic domains?
No. The device is specified only for 4.5–5.5 V VCC operation and requires TTL-level inputs (VIH ≥ 2.0 V, VIL ≤ 0.8 V). Its inputs are not 5 V-tolerant when powered from 3.3 V, and it lacks level-shifting circuitry. Interfacing with 3.3 V systems requires external translators or voltage dividers.
What is the maximum capacitive load the 74ABT08DB,118 can drive while maintaining specified propagation delay?
The datasheet specifies dynamic characteristics with CL = 50 pF (including jig and probe capacitance). Driving loads >50 pF increases tPLH/tPHL nonlinearly; at 100 pF, delay increases by ~35% versus nominal. For timing-critical paths, keep total load ≤50 pF or characterize empirically.
Can the IOFF feature be used to isolate the 74ABT08DB,118 outputs during system reset without powering down VCC?
No. IOFF activates only when VCC = 0 V. It does not respond to reset signals or logic-level controls. To isolate outputs during reset while VCC remains active, external tri-state buffers or analog switches are required.
Is the 74ABT08DB,118 pin-compatible with older 74LS08 or 74F08 devices in SO14 packages?
Yes - identical pinout (1A–4Y, GND, VCC) and same SO14 (SOT108-1) mechanical footprint. However, ABT logic offers faster speed, higher drive, and IOFF protection not present in LS/F families, enabling direct drop-in replacement with improved robustness.
