Product details
Overview
74ABT32DB,112 from Nexperia is a quad 2-input OR gate logic IC in SO14 (SOT108-1) package, operating from 4.5 V to 5.5 V supply, with IOFF partial power-down protection, -40 °C to +85 °C temperature range, and propagation delays as low as 1.0 ns. It serves as a high-speed combinational logic building block in bus interface, address decoding, and control signal routing circuits.
For engineers reviewing the 74ABT32DB,112 datasheet, 74ABT32DB,112 pinout, 74ABT32DB,112 application, or 74ABT32DB,112 equivalent, this device is selected for TTL-compatible level translation, low-skew multi-gate logic distribution, and systems requiring backflow current suppression during partial power-down sequencing.
Technical Context
The 74ABT32DB,112 implements four independent OR gates using BiCMOS technology, enabling TTL-level input compatibility and 20 mA sink / 15 mA source output drive. Its IOFF circuitry actively disables outputs when VCC = 0 V, limiting power-off leakage to ±100 μA while blocking reverse current flow.
Propagation delay is specified at 1.0–3.8 ns (LOW→HIGH) and 1.0–3.2 ns (HIGH→LOW) across full temperature range, with output skew ≤0.5 ns between any two gates - critical for synchronous enable/valid signal generation in parallel data paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures robust operation across industrial-grade 5 V rails with ±10 % tolerance. |
| Propagation Delay (tPLH/tPHL) | 1.0–3.8 ns - enables sub-4 ns timing-critical logic decisions in high-speed control paths. |
| Output Drive (IOL/IOH) | 20 mA sink / 15 mA source - directly drives multiple TTL inputs or small capacitive loads without buffering. |
| IOFF Leakage Current | ±100 μA at VCC = 0 V - prevents damaging backflow during hot-swap or partial power-down sequences. |
| Operating Temperature | -40 °C to +85 °C - supports deployment in industrial control cabinets and outdoor embedded enclosures. |
| ESD Protection | HBM >2000 V, CDM >1000 V - withstands handling and board-level ESD events without latch-up or parametric shift. |
| Input Thresholds (VIH/VIL) | VIH ≥2.0 V, VIL ≤0.8 V - guarantees clean recognition of TTL logic levels across voltage and temperature. |
Pinout & Package
74ABT32DB,112 is supplied in SO14 (SOT108-1) plastic small outline package: 14-pin, 3.9 mm body width, 1.27 mm lead pitch, gull-wing leads, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | 1A, 2A, 3A, 4A | First input per OR gate - accepts TTL-compatible logic signals; internally tied to BiCMOS input stage. |
| 2, 5, 10, 13 | 1B, 2B, 3B, 4B | Second input per OR gate - dual-input structure allows flexible Boolean combination of control signals. |
| 3, 6, 8, 11 | 1Y, 2Y, 3Y, 4Y | OR output per gate - active-high, push-pull, capable of sourcing/sinking up to 20 mA. |
| 7 | GND | Ground reference - all internal logic and I/O referenced to this node; must be low-impedance connection. |
| 14 | VCC | Positive supply - powers internal BiCMOS circuitry; IOFF function activates when this pin is at 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| IOFF Partial Power-Down | Disables outputs and limits leakage to ±100 μA when VCC = 0 V - essential for hot-pluggable modules and power sequenced subsystems. |
| TTL-Level Input Compatibility | VIH ≥2.0 V and VIL ≤0.8 V - eliminates need for level-shifting buffers when interfacing with legacy 5 V TTL logic families. |
| Low Output Skew | ≤0.5 ns between any two outputs - ensures deterministic timing alignment across parallel gate outputs in enable or strobe applications. |
| BiCMOS Output Drive | 20 mA sink / 15 mA source - supports fan-out of ≥10 standard TTL loads without external drivers. |
| Latch-Up Immunity | Exceeds 500 mA per JESD78B Class II Level A - prevents destructive latch-up under transient overvoltage or ground bounce conditions. |
Applications
| Bus Arbitration Logic | Address Decoder Enable |
|---|---|
|
Use Scenario: Resolving contention among multiple masters on a shared parallel bus by OR-ing request signals before granting access. IC Role / Device Role / Timing Role: Combinational OR gate aggregating distributed BUSREQ# signals into a single priority arbitration input. Use Value: Sub-4 ns propagation ensures minimal arbitration latency; IOFF prevents backfeed when one master powers down mid-cycle. |
Use Scenario: Generating chip-select pulses for memory or peripheral ICs based on decoded upper address bits. IC Role / Device Role / Timing Role: Final-stage OR gate combining decoded address segments to assert CS# only when full address matches. Use Value: Tight 0.5 ns output skew guarantees simultaneous activation of multiple peripherals; TTL-compatible inputs simplify integration with address latches. |
| Power Sequencing Monitor | System Reset Aggregation |
|
Use Scenario: Monitoring individual rail OK signals (e.g., +3.3 V_OK, +5 V_OK, +12 V_OK) to generate a global POWER_GOOD signal. IC Role / Device Role / Timing Role: OR-ing independent rail status flags to produce a composite "all-rails-stable" assertion. Use Value: IOFF blocks reverse current if one rail collapses while others remain active - preserving integrity of monitoring logic. |
Use Scenario: Combining watchdog timeout, manual reset, and brown-out detector outputs into a unified system reset pulse. IC Role / Device Role / Timing Role: Active-high OR gate ensuring RESET# asserts if any fault condition occurs. Use Value: 20 mA output drive directly loads reset input capacitance of MCUs or FPGAs; -40 °C to +85 °C rating ensures reliability in wide-temperature environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ABT32N | Same logic function and pinout; identical SO14 package; TI version with slightly higher ICC (max 50 μA vs. Nexperia's 50 μA typical). | No IOFF support - unsuitable for partial power-down systems requiring backflow prevention. | Select when IOFF is not required and TI supply chain preference applies. |
| 74LVC32APW | Lower voltage operation (1.65–3.6 V); TSSOP14 package; no IOFF; 32 mA IOL but slower tPD (3.2 ns min). | Designed for 3.3 V systems only; incompatible with 5 V TTL interfaces without level translation. | Choose for cost-sensitive 3.3 V designs where 5 V tolerance and IOFF are unnecessary. |
Compared with SN74ABT32N and 74LVC32APW, the 74ABT32DB,112 uniquely delivers IOFF-enabled partial power-down capability within a 5 V TTL-compatible footprint - making it the sole option for hot-swap-capable industrial controllers requiring zero-backflow logic gating.

FAQ
Does 74ABT32DB,112 support mixed-voltage interfacing?
No. The 74ABT32DB,112 is strictly a 4.5–5.5 V device with TTL-compatible input thresholds (VIH ≥2.0 V, VIL ≤0.8 V). It does not support direct interfacing with 3.3 V or lower logic families without external level-shifting circuitry, as its inputs are not 5 V-tolerant in sub-4.5 V supply conditions and lack dedicated voltage translation architecture.
What is the maximum capacitive load the outputs can drive reliably?
The outputs are characterized up to 50 pF load capacitance per Table 8 of the datasheet, with propagation delay and skew specifications guaranteed under those conditions. Driving >50 pF may increase tPLH/tPHL beyond 3.8 ns and degrade output skew; for heavier loads, external buffer stages or reduced slew-rate termination should be used.
Can 74ABT32DB,112 be used in automotive applications?
No. The 74ABT32DB,112 is not automotive-qualified. Nexperia explicitly states in Section 14 that unless the data sheet expressly declares automotive qualification, the product is neither tested nor warranted for automotive use - including AEC-Q100 stress testing or extended temperature operation beyond -40 °C to +85 °C.
How does IOFF behave when VCC is ramping during power-up?
IOFF activates only when VCC is near 0 V (≤0.2 V), per characterization in Table 6. During power-up ramp, the device transitions from IOFF-disabled to fully functional once VCC exceeds ~1.5 V; no undefined output state or glitch occurs, as confirmed by functional description and static characteristics across the recommended operating range.
