Product details
Overview
74ABT04DB,112 from Nexperia is a hex inverter logic IC with BiCMOS technology, operating across 4.5 V to 5.5 V supply, delivering 2.2 ns typical propagation delay (tPLH/tPHL), IOFF-enabled partial power-down protection, and -40 °C to +85 °C industrial temperature range - used for signal inversion and level translation in bus interface circuits.
For engineers reviewing the 74ABT04DB,112 datasheet, 74ABT04DB,112 pinout, 74ABT04DB,112 application, or 74ABT04DB,112 equivalent, this device is selected for TTL-compatible digital logic inversion where low skew (0.4 ns max), high drive strength (20 mA sink), and robust ESD immunity (2000 V HBM) are required in space-constrained SO14 layouts.
Technical Context
The 74ABT04DB,112 implements six independent CMOS-compatible inverters with BiCMOS output stages, enabling fast switching while maintaining TTL-level input thresholds (VIL ≤ 0.8 V, VIH ≥ 2.0 V) and rail-to-rail output swing under load. Its IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current during hot-swap or partial power-down sequences.
Propagation delay is tightly controlled (tPLH/tPHL ≤ 4.1/3.0 ns over full temperature range), and output skew between any two channels is guaranteed ≤ 0.5 ns - critical for synchronized multi-bit signal inversion in data buses and clock distribution networks.
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 systems without level shifters. |
| Propagation Delay | 2.2 ns typical (tPLH), 1.6 ns typical (tPHL) at VCC = 5.0 V - enables reliable operation in >200 MHz toggle-rate digital control paths. |
| Output Drive | 20 mA sink / 15 mA source - supports direct fan-out to ≥10 LS-TTL loads or termination of 50 Ω transmission lines. |
| IOFF Leakage | ±100 μA max at VCC = 0 V - prevents destructive back-current during live insertion or system sleep states. |
| ESD Rating | HBM: >2000 V, CDM: >1000 V - meets IEC 61000-4-2 Level 2 requirements for board-level handling robustness. |
| Operating Temp | -40 °C to +85 °C - qualified for industrial automation, telecom infrastructure, and embedded control environments. |
| Input Thresholds | VIL ≤ 0.8 V, VIH ≥ 2.0 V - guarantees unambiguous logic recognition across voltage tolerances and noise margins. |
Pinout & Package
74ABT04DB,112 is packaged in SO14 (SOT108-1): plastic small outline, 14-pin, 3.9 mm body width, 1.27 mm lead pitch, surface-mountable with gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Input (1A–6A) | Independent logic inputs accepting TTL-compatible voltage levels; each drives one inverter stage. |
| 2, 4, 6, 8, 10, 12 | Output (1Y–6Y) | Inverted logic outputs with active pull-up/pull-down; capable of 20 mA sink and 15 mA source. |
| 7 | GND | Reference ground for all inputs, outputs, and internal circuitry; must be low-impedance for noise immunity. |
| 14 | VCC | Main supply rail (4.5–5.5 V); powers all six inverters and IOFF control circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| IOFF Partial Power-Down | Outputs enter high-impedance state when VCC = 0 V, preventing backfeed into powered subsystems during hot-swap or standby. |
| BiCMOS Output Stage | Combines bipolar speed and CMOS low static power, achieving <2.5 ns propagation delay with 20 mA drive capability. |
| TTL-Compatible Interface | Accepts standard TTL input thresholds and drives TTL/LS-TTL loads directly - eliminates external level-shifting components. |
| Low Output Skew | ≤0.5 ns skew between any two outputs ensures timing coherence across multi-bit inverted signals (e.g., address/data buses). |
| Latch-Up Immunity | Exceeds 500 mA per JESD78B Class II - protects against destructive latch-up under transient overvoltage or ESD stress. |
Applications
| Industrial Bus Interface | Microcontroller GPIO Expansion |
|---|---|
|
Use Scenario: Inverting control signals on RS-485 transceiver enable lines and SPI chip-select routing in PLC backplanes. IC Role / Device Role / Timing Role: Signal polarity correction and noise-immune buffering for bidirectional bus arbitration logic. Use Value: Ensures clean, skew-matched inversion across six parallel control lines, eliminating race conditions in multi-drop communication. |
Use Scenario: Expanding limited MCU GPIO count to drive LED arrays, relay drivers, and opto-isolator inputs in HVAC controllers. IC Role / Device Role / Timing Role: Logic-level translation and current gain for microcontroller outputs unable to sink 20 mA directly. Use Value: Enables direct connection of 3.3 V or 5 V MCU pins to higher-current peripherals without discrete transistor stages. |
| Legacy System Emulation | Digital Test Fixture Logic |
|

IC Role / Device Role / Timing Role: Drop-in functional replacement preserving original timing behavior and pinout compatibility. Use Value: Maintains identical propagation delay envelope (≤4.1 ns) and input/output voltage thresholds for seamless legacy integration. |
Use Scenario: Generating complementary test patterns and inverted strobes in automated PCB functional testers and boundary-scan support hardware. IC Role / Device Role / Timing Role: Synchronized signal inversion for stimulus generation and response capture timing alignment. Use Value: Sub-nanosecond skew ensures precise phase relationship between primary and inverted test vectors across all six channels. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ABT04DBR | TI version in same SO14 package; identical VCC range and IOFF function, but tPHL = 1.8 ns typ (vs. 1.6 ns) and VOL = 0.4 V max (vs. 0.35 V). | Marginally higher output low voltage may reduce noise margin in high-fanout LS-TTL loads. | Select when TI supply chain alignment or dual-sourcing is required; verify VOL compliance in worst-case loading. |
| 74LVC04PW,118 | Nexperia's 3.3 V-only LVC variant in TSSOP14; no IOFF, lower drive (24 mA), but wider VCC range (1.2–3.6 V) and smaller footprint. | Not suitable for 5 V systems or partial power-down use cases; requires level shifting if interfacing with 5 V logic. | Choose only for new 3.3 V designs prioritizing size and low voltage operation - not a drop-in replacement. |
Compared with SN74ABT04DBR and 74LVC04PW,118, the 74ABT04DB,112 uniquely balances 5 V TTL compatibility, IOFF safety, and sub-2 ns propagation in SO14 - making it optimal for industrial upgrades where legacy voltage and power sequencing constraints apply.

FAQ
Does 74ABT04DB,112 support mixed-voltage operation between input and output rails?
No. The device operates from a single 4.5–5.5 V VCC supply and does not support dual-supply or level-shifting functionality. Inputs and outputs are referenced solely to this rail; interfacing with lower-voltage logic requires external translators or resistor-based biasing verified per application conditions.
Can 74ABT04DB,112 be used in hot-swap applications with live backplane insertion?
Yes - its IOFF circuitry actively disables outputs when VCC drops to 0 V, limiting back-current to ±100 μA maximum. This allows safe insertion into powered backplanes, provided GND and signal pins make contact before VCC, and system-level current limiting is implemented per JEDEC JESD78B Class II guidelines.
What is the maximum capacitive load the outputs can drive while maintaining specified timing?
The datasheet specifies dynamic characteristics with 50 pF load (Table 8). While outputs can drive heavier loads, propagation delay increases linearly with capacitance; for loads >100 pF, measured tPLH/tPHL exceeds 5 ns. Use series termination or buffer stages for >150 pF routing to maintain timing integrity.
Is 74ABT04DB,112 qualified for automotive applications?
No. It is rated for industrial temperature range (-40 °C to +85 °C) and carries no AEC-Q100 qualification. Nexperia explicitly states non-automotive qualification in legal disclaimers; use only in non-safety-critical industrial, computing, or consumer equipment unless independently validated per automotive requirements.
