Product details
Overview
74ABT125PW,112 from Nexperia is a quad 3-state buffer/line driver with independent active-low output enable inputs (1OE–4OE), designed for bidirectional bus interface and signal isolation in TTL-compatible digital systems. It operates from 4.5 V to 5.5 V, delivers ±64 mA output drive (LOW/HIGH), supports partial power-down via IOFF circuitry, and is rated for -40 °C to +85 °C industrial temperature range.
For engineers reviewing the 74ABT125PW,112 datasheet, 74ABT125PW,112 pinout, 74ABT125PW,112 application, or 74ABT125PW,112 equivalent, key selection criteria include 3-state timing (tPZH ≤ 5.9 ns), IOFF-enabled hot-swap capability, BiCMOS-level drive strength, and TSSOP14 package compatibility with high-density PCB layouts.
Technical Context
The device implements four independent non-inverting buffers, each with dedicated active-low output enable control. Its BiCMOS process enables TTL-level input compatibility and rail-to-rail output swing while maintaining low propagation delay (tPLH/tPHL ≤ 4.6 ns at VCC = 5.0 V).
IOFF circuitry actively disables outputs during power-down, blocking backflow current when VCC = 0 V - critical for live insertion and system-level power sequencing. Input clamping and ESD protection (HBM > 2000 V, CDM > 1000 V) ensure robustness in noisy industrial environments.
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 resilience |
| Output drive (LOW) | +64 mA - drives heavy capacitive loads or multiple TTL inputs without external buffering |
| Output drive (HIGH) | -32 mA - sustains logic HIGH under significant fan-out or pull-down loading |
| Propagation delay | tPLH/tPHL ≤ 4.6 ns - enables sub-200 MHz bus operation with tight timing margins |
| IOFF leakage | ±100 μA at VCC = 0 V - prevents damaging back-current during hot-swap or partial power-down |
| Operating temperature | -40 °C to +85 °C - qualified for industrial-grade embedded control and communications equipment |
| ESD rating (HBM) | >2000 V - meets JEDEC JS-001 Class 2 for handling and board assembly robustness |
Pinout & Package
TSSOP14 plastic thin shrink small outline package (SOT402-1); 14-lead, 4.4 mm body width, 0.65 mm pitch; thermally enhanced for high-density routing and improved power dissipation vs. SO14.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | 1OE, 2OE, 3OE, 4OE | Active-low output enable - each independently controls one buffer's 3-state output |
| 2, 5, 9, 12 | 1A, 2A, 3A, 4A | Data inputs - TTL-compatible, no internal pull-ups, disabled during 3-state mode |
| 3, 6, 8, 11 | 1Y, 2Y, 3Y, 4Y | Buffered outputs - high-impedance (Z) when corresponding OE is HIGH |
| 7 | GND | Ground reference - common return for all I/O and supply paths |
| 14 | VCC | Positive supply - powers internal BiCMOS circuitry; requires local decoupling |
Key Features
| Feature | Design Value |
|---|---|
| BiCMOS high-speed architecture | Combines bipolar speed and CMOS low static power for <4.6 ns propagation delay with 64 mA drive |
| IOFF partial power-down | Prevents destructive back-current during VCC ramp-down or hot-swap - eliminates need for external isolation |
| Power-up 3-state | Outputs remain high-impedance until VCC stabilizes - avoids bus contention during power sequencing |
| Latch-up immunity | Exceeds 500 mA per JESD78B Class II - ensures reliability in electrically noisy industrial environments |
| Live insertion support | Validated for hot-plug applications due to IOFF + ESD + 3-state behavior - reduces system downtime |
Applications
| Industrial Bus Interface | Memory Address Buffering |
|---|---|
Use Scenario: Isolating microcontroller address/data buses from peripheral expansion slots in programmable logic controllers. IC Role / Device Role / Timing Role: Quad 3-state buffer providing direction-controlled signal isolation between CPU and add-on modules. Use Value: Enables dynamic bus sharing with tPZH ≤ 5.9 ns enable-to-output delay and IOFF protection during module insertion/removal. | Use Scenario: Driving high-capacitance memory address lines in FPGA-based data acquisition systems. IC Role / Device Role / Timing Role: Level-shifting and fan-out buffer for 16-bit address bus with TTL-compatible input thresholds. Use Value: Delivers +64 mA sink current to overcome trace capacitance and maintain setup/hold timing across 10+ DRAM chips. |
| Test Equipment Signal Routing | Digital I/O Expansion |
Use Scenario: Multiplexing digital stimulus signals across multiple DUT channels in automated test fixtures. IC Role / Device Role / Timing Role: Output-enable-gated signal distributor enabling channel-selective signal injection.

IC Role / Device Role / Timing Role: Bidirectional bus transceiver buffer supporting both input sampling and output driving modes. Use Value: TTL-compatible inputs accept direct sensor switch outputs; 3-state outputs prevent conflicts when multiple expanders share a common bus. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC125PW,118 | Lower VCC range (1.65–3.6 V); 24 mA drive; no IOFF; LVC logic family | Not suitable for 5 V TTL systems; lacks partial power-down protection | Select only for 3.3 V-only designs requiring lower power and smaller die size |
| SN74ABT125PW | Identical electrical specs and pinout; Texas Instruments branding; same SOT402-1 package | No functional difference; qualifies as second-source for supply chain diversification | Preferred when TI sourcing preference or dual-sourcing strategy applies |
Compared with 74ABT125PW,112, the 74LVC125PW,118 sacrifices 5 V compatibility and IOFF protection for lower voltage operation, while SN74ABT125PW offers identical performance with alternate supply chain assurance - making the Nexperia part optimal for legacy 5 V industrial bus integrity and hot-swap safety.

FAQ
What is the maximum allowable output current per pin for 74ABT125PW,112?
The device supports +64 mA sink current (IOL) and -32 mA source current (IOH) per output under recommended operating conditions (VCC = 4.5–5.5 V). These values are measured at VO = 0.55 V (LOW) and VO = 2.0 V (HIGH), respectively, and reflect guaranteed drive capability into standard TTL loads without exceeding thermal limits in the TSSOP14 package.
Does 74ABT125PW,112 support hot-plug or live insertion?
Yes - its integrated IOFF circuitry disables outputs and blocks backflow current when VCC = 0 V, and its power-up 3-state behavior ensures outputs remain high-impedance until supply stabilizes. Combined with latch-up immunity (>500 mA) and HBM ESD protection (>2000 V), it is explicitly qualified for live insertion in backplane and modular industrial systems per datasheet Section 1 and 2.
Can 74ABT125PW,112 interface directly with 3.3 V logic inputs?
No - its inputs require VIH ≥ 2.0 V and VIL ≤ 0.8 V at VCC = 5.0 V, but it does not guarantee recognition of 3.3 V logic HIGH levels when driven by 3.3 V sources. For mixed-voltage interfacing, level-shifting circuitry or a 3.3 V–tolerant buffer like 74LVC125 is required; this device is strictly optimized for 5 V TTL-compatible systems.
What is the thermal derating behavior of the TSSOP14 package?
The TSSOP14 (SOT402-1) package has a total power dissipation limit of 500 mW at Tamb = -40 °C to +85 °C, derating linearly at 7.3 mW/K above +81 °C. This means usable power drops to ~420 mW at +95 °C ambient, requiring careful thermal layout (e.g., copper pour under exposed pad if used) in high-density or elevated-temperature deployments.
