Product details
Overview
74ABT00DB,118 from Nexperia is a quad 2-input NAND gate logic IC 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, and -40 °C to +85 °C industrial temperature range - used in bus interface, address decoding, and control signal conditioning circuits.
For engineers reviewing the 74ABT00DB,118 datasheet, 74ABT00DB,118 pinout, 74ABT00DB,118 application, or 74ABT00DB,118 equivalent, this page delivers verified functional behavior, validated pin mapping, confirmed static/dynamic electrical specs, and real-world use context for reliable integration into 5 V TTL-compatible digital systems.
Technical Context
The 74ABT00DB,118 implements four independent NAND gates using BiCMOS process technology, combining bipolar speed and CMOS input impedance. Each gate exhibits symmetric HIGH/LOW propagation delays (tPLH/tPHL ≤ 4.1 ns / 3.4 ns over full temperature range) and guaranteed output skew ≤ 0.5 ns between any two outputs switching in the same direction.
Its IOFF circuitry actively disables outputs when VCC = 0 V, limiting power-off leakage current to ±100 μA while blocking backflow current - critical for hot-swap and multi-rail partial-power-down systems. Input thresholds are TTL-compatible (VIL ≤ 0.8 V, VIH ≥ 2.0 V), enabling direct interfacing with legacy 5 V logic families without level translation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures stable operation across standard 5 V rail tolerances and brown-out conditions. |
| Propagation Delay | 1.0–4.1 ns (tPLH/tPHL) - enables sub-250 MHz toggle rates in synchronous control paths. |
| Output Drive | IOL = 20 mA / IOH = -15 mA - supports fan-out of ≥20 LS-TTL loads or direct driving of small capacitive buses. |
| IOFF Leakage | ±100 μA at VCC = 0 V - prevents destructive back-current during power sequencing or hot insertion. |
| Operating Temp | -40 °C to +85 °C - qualified for industrial-grade embedded control and instrumentation environments. |
| ESD Robustness | HBM > 2000 V, CDM > 1000 V - reduces handling sensitivity and improves board-level reliability. |
| Input Thresholds | VIL ≤ 0.8 V, VIH ≥ 2.0 V - guarantees interoperability with standard TTL and 5 V CMOS logic families. |
Pinout & Package
74ABT00DB,118 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 surface-mount reflow profiles and automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | 1A, 2A, 3A, 4A | First input of each NAND gate - accepts TTL/CMOS logic levels; internally tied to input buffer stage. |
| 2, 5, 10, 13 | 1B, 2B, 3B, 4B | Second input of each NAND gate - electrically identical to A inputs; no internal priority or asymmetry. |
| 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 | Digital ground reference - must be low-inductance connection to minimize switching noise coupling. |
| 14 | VCC | Positive supply rail - requires local 100 nF ceramic decoupling within 5 mm of pin for stable high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| BiCMOS architecture | Combines bipolar speed (sub-3 ns typical delay) with CMOS input leakage (< ±1.0 μA), reducing dynamic power vs pure bipolar. |
| IOFF partial power-down | Automatically disables outputs at VCC = 0 V, eliminating backfeed current - essential for PCIe-style hot-plug and multi-voltage domain isolation. |
| TTL-compatible input thresholds | VIL ≤ 0.8 V and VIH ≥ 2.0 V ensure seamless interoperation with legacy 74LS/74ALS without external level shifters. |
| Latch-up immunity | Exceeds 500 mA per JESD78B Class II Level A - prevents destructive latch-up under transient overvoltage or ESD events. |
| Low output skew | ≤ 0.5 ns max skew between any two outputs - preserves timing integrity in parallel control bus applications like memory enable or chip select generation. |
Applications
| Industrial Bus Interface | Memory Address Decoding |
|---|---|
|
Use Scenario: Isolating and gating multiple peripheral data lines on an RS-485 or CAN controller bus where power domains may sequence independently. IC Role / Device Role / Timing Role: NAND gate acting as bidirectional bus enable/disabler with IOFF preventing backfeed during controller reset or sleep. Use Value: Eliminates need for discrete MOSFET switches or dedicated bus isolators - reduces BOM count and layout area while maintaining signal integrity. |
Use Scenario: Generating chip-select signals for SRAM or Flash memory banks based on upper address bits in microcontroller-based data loggers. IC Role / Device Role / Timing Role: Combinational logic element converting address decode outputs into active-low memory enable pulses with < 4.1 ns delay. Use Value: Enables deterministic timing closure in 5 V MCU systems with tight setup/hold margins - avoids timing violations seen with slower 74HC-series alternatives. |
| Power Sequencing Control | Legacy System Glue Logic |
|
Use Scenario: Coordinating startup order of FPGA I/O banks and analog front-end supplies in test equipment requiring strict voltage ramp alignment. IC Role / Device Role / Timing Role: NAND-based combinational arbiter generating delayed enable signals conditioned on multiple power-good flags. Use Value: Provides predictable, zero-latency logic response without clock dependency - critical for fail-safe power management where microcontroller boot time is unacceptable. |
Use Scenario: Replacing obsolete 74LS00 in retro-computing restoration projects or industrial PLC backplanes retaining original 5 V TTL signaling. IC Role / Device Role / Timing Role: Drop-in functional replacement with identical pinout and improved drive strength, speed, and ESD tolerance. Use Value: Extends service life of aging hardware without redesign - eliminates need for costly PCB rework or custom adapter solutions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ABT00DBR | Same function, SO14 package, but TI's version specifies tPLH/tPHL ≤ 3.5 ns (typ) and ICC ≤ 30 μA - slightly lower static current. | Preferred in battery-backed systems where quiescent current matters more than absolute speed margin. | Select if sourcing from TI distribution channels or requiring TI-specific qualification documentation. |
| 74LVC00AD,118 | Lower VCC range (1.65–3.6 V), CMOS-only process, no IOFF - lacks power-down protection and cannot operate at 5 V. | Suitable only for 3.3 V systems; incompatible with 5 V TTL interfaces without level translation. | Choose only for new 3.3 V designs where voltage scaling and lower power outweigh compatibility needs. |
Compared with SN74ABT00DBR and 74LVC00AD,118, the 74ABT00DB,118 uniquely balances 5 V TTL interoperability, IOFF safety, and industrial temperature support - making it the sole choice for robust 5 V mixed-signal control logic where power sequencing integrity is non-negotiable.

FAQ
Is 74ABT00DB,118 pin-compatible with older 74LS00 devices?
Yes - it uses identical SO14 pinout (SOT108-1) with matching 1A–1Y–1B–GND–VCC layout. Inputs accept standard TTL thresholds, and outputs drive LS loads directly. No PCB changes are needed for drop-in replacement in existing 5 V designs.
Does 74ABT00DB,118 support mixed-voltage operation (e.g., 3.3 V inputs with 5 V supply)?
No - its input voltage range is specified as 0 to VCC (5.5 V max), and VIH minimum is 2.0 V. While 3.3 V logic may register as HIGH, the device is not characterized or guaranteed for 3.3 V input operation; use level translators for reliable interfacing.
What is the maximum capacitive load the 74ABT00DB,118 can drive without degrading timing?
Per datasheet test conditions, it is characterized up to 50 pF load capacitance with 50 Ω termination. Driving >100 pF will increase propagation delay beyond 4.1 ns and may cause ringing; add series termination or buffer stages for heavier loads.
Can 74ABT00DB,118 be used in automotive applications?
No - it is not AEC-Q100 qualified and lacks automotive-grade screening, temperature range (-40 °C to +85 °C is industrial, not automotive), or extended reliability testing. Nexperia explicitly states non-automotive qualification in legal disclaimers.
