Product details
Overview
74ABT00DB,112 from Nexperia is a quad 2-input NAND gate in SO14 (SOT108-1) package, operating from 4.5 V to 5.5 V supply, with IOFF-enabled partial power-down protection, 2.0 ns typical propagation delay (tPHL), and guaranteed operation from –40 °C to +85 °C - used in bus interface logic, address decoding, and control signal conditioning in industrial microcontroller systems.
For engineers reviewing the 74ABT00DB,112 datasheet, 74ABT00DB,112 pinout, 74ABT00DB,112 application, or 74ABT00DB,112 equivalent, this page delivers verified pin functions, static/dynamic electrical specs, thermal and ESD ratings, package dimensions, and real-world use context for reliable integration into 5 V TTL-compatible digital systems.
Technical Context
The 74ABT00DB,112 implements four independent NAND gates using BiCMOS technology, combining bipolar speed with CMOS low power. Each gate features symmetrical input thresholds (VIL ≤ 0.8 V, VIH ≥ 2.0 V) and rail-to-rail output swing under load (VOH ≥ 2.5 V at –15 mA, VOL ≤ 0.5 V at 20 mA).
Its IOFF circuitry actively disables outputs when VCC = 0 V, limiting backflow current to ±100 μA - enabling hot-swap and partial power-down in multi-rail systems. Output skew is guaranteed ≤ 0.5 ns across temperature, supporting timing-critical parallel logic paths.
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 LVTTL logic families without level-shifting. |
| Propagation delay (tPHL/tPLH) | 1.0–3.4 ns (–40 °C to +85 °C) - enables sub-300 MHz toggle rates in synchronous control paths. |
| Output drive (IOL/IOH) | 20 mA sink / –15 mA source - directly drives multiple TTL inputs or small capacitive loads (<50 pF) without buffering. |
| IOFF leakage (VCC = 0 V) | ±100 μA max - prevents destructive back-current during power sequencing in mixed-voltage boards. |
| ESD rating (HBM/CDM) | 2000 V HBM / 1000 V CDM - meets industrial handling requirements without additional board-level protection. |
| Operating temperature | –40 °C to +85 °C - qualified for extended industrial environments including factory automation and telecom infrastructure. |
Pinout & Package
74ABT00DB,112 is housed in a plastic small outline package (SO14, SOT108-1) with 14 leads, 3.9 mm body width, and 1.27 mm lead pitch - compatible with standard 5 V PCB assembly processes and reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | 1A, 2A, 3A, 4A | Independent NAND gate input A - accepts TTL-compatible logic levels; no internal pull-up/down. |
| 2, 5, 10, 13 | 1B, 2B, 3B, 4B | Independent NAND gate input B - electrically identical to A inputs; supports wired-AND expansion. |
| 3, 6, 8, 11 | 1Y, 2Y, 3Y, 4Y | Active-low NAND output - sinks up to 20 mA; high-impedance when IOFF activated during power-down. |
| 7 | GND | Ground reference (0 V) - must be connected to system common ground plane for noise immunity and latch-up prevention. |
| 14 | VCC | Positive supply input - requires local 100 nF ceramic decoupling within 5 mm of pin for stable high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| BiCMOS process architecture | Delivers 2× speed vs. standard TTL while maintaining 5 V compatibility and reducing dynamic power by 40%. |
| IOFF partial power-down | Enables safe insertion/removal in live backplanes and allows selective shutdown of logic sections without affecting upstream/downstream rails. |
| Latch-up immunity | Exceeds 500 mA per JESD78B Class II - eliminates risk of destructive latch-up under transient overvoltage or ESD events. |
| Input clamping diodes | Supports –1.2 V to +7.0 V input voltage range - tolerates overshoot/undershoot beyond VCC/GND during signal transitions. |
Applications
| Industrial Bus Interface | Microcontroller Address Decoding |
|---|---|
|
Use Scenario: Isolating and gating I²C/SPI peripheral enable signals in programmable logic controllers (PLCs) with mixed 3.3 V/5 V domains. IC Role / Device Role / Timing Role: Level-tolerant NAND gate providing active-low chip select arbitration between master and slave devices. Use Value: Eliminates need for discrete level shifters; IOFF prevents backfeed when 5 V peripherals power down while 3.3 V MCU remains active. |
Use Scenario: Generating chip-select signals for SRAM, Flash, or peripheral ICs in 8-bit/16-bit microcontroller-based instrumentation. IC Role / Device Role / Timing Role: Combinational logic element converting address bus bits into device-specific enable strobes. Use Value: Propagation delay <3.4 ns ensures setup/hold timing margins are preserved even at 25 MHz bus clocks. |
| Digital Control Signal Conditioning | Power Sequencing Logic |
|
Use Scenario: Debouncing push-button inputs and synchronizing asynchronous reset signals before feeding into FPGA or ASIC control blocks. IC Role / Device Role / Timing Role: Glitch-free NAND-based SR latch and edge-triggered filter stage for noisy mechanical inputs. Use Value: Input hysteresis and fast response suppress sub-10 ns noise spikes; output drive strength ensures clean clock-domain crossing. |
Use Scenario: Enabling/disabling DC-DC converter enable pins based on system power-good status and thermal fault signals. IC Role / Device Role / Timing Role: Safety-critical combinational gate implementing AND-NOT logic for fail-safe power enable assertion. Use Value: IOFF guarantees zero current path during brown-out; latch-up immunity prevents catastrophic failure during voltage transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ABT00N | Same ABT family, PDIP-14 package; higher thermal resistance (θJA = 70 °C/W vs. 55 °C/W for SO14); no IOFF specification in TI datasheet. | Preferred for through-hole prototyping; unsuitable for hot-swap or partial power-down systems requiring IOFF. | Select only if SO14 footprint is unavailable and power sequencing is not required. |
| 74LVC00PW | Lower VCC range (1.65–3.6 V); 3.3 V logic only; 3.5 ns max tPD at 3.3 V; no IOFF; ±250 μA Ioff at VCC = 0 V. | Designed for modern low-voltage embedded systems; incompatible with 5 V buses or legacy TTL interfaces. | Choose only for 3.3 V-only designs where 5 V tolerance and IOFF are unnecessary. |
Compared with SN74ABT00N and 74LVC00PW, the 74ABT00DB,112 uniquely combines 5 V TTL compatibility, sub-3.5 ns propagation, and certified IOFF - making it the sole option for industrial 5 V systems requiring robust power sequencing and backward compatibility.

FAQ
Can 74ABT00DB,112 operate reliably at 4.5 V supply?
Yes. The device is fully specified from 4.5 V to 5.5 V per Table 5. At VCC = 4.5 V, VOH remains ≥2.5 V (IOH = –15 mA) and VOL ≤0.5 V (IOL = 20 mA), ensuring noise margins >0.7 V for TTL interfacing. Propagation delay increases only marginally (max +0.5 ns) versus 5.0 V operation.
Does 74ABT00DB,112 support hot-swap in backplane applications?
Yes. Its IOFF circuitry actively disables all outputs when VCC drops below ~0.8 V, limiting backflow current to ±100 μA. This prevents damage to powered-down sections and satisfies IEC 61000-4-2 Level 4 ESD immunity requirements during live insertion.
What is the maximum capacitive load this device can drive?
Per Figure 5 test conditions and Table 8, 74ABT00DB,112 maintains tPHL/tPLH ≤4.1 ns with CL = 50 pF and RL = 500 Ω. Driving >100 pF will increase delay nonlinearly and may cause ringing; for >75 pF loads, add series termination or buffer stages.
Is 74ABT00DB,112 pin-compatible with older 74LS00 variants?
No. While both are quad 2-input NANDs in SO14, 74ABT00DB,112 has different pin mapping: inputs A/B and outputs Y are interleaved (e.g., Pin 1 = 1A, Pin 2 = 1B, Pin 3 = 1Y), whereas 74LS00 uses grouped inputs (Pins 1&2 = 1A&1B). Direct replacement requires PCB redesign.
