Product details
Overview
SN74LVC125AIPWREP from Texas Instruments is a quadruple bus buffer gate with 3-state outputs, designed for 1.65 V to 3.6 V operation in mixed-voltage digital systems. It provides four independent noninverting buffers, each controlled by its own output-enable (OE) input, supporting level translation between 3.3-V and 5-V logic domains in industrial control backplanes and FPGA I/O expansion interfaces.
For engineers reviewing the SN74LVC125AIPWREP datasheet, SN74LVC125AIPWREP pinout, SN74LVC125AIPWREP application, or SN74LVC125AIPWREP equivalent, this device is selected for low-voltage bus driving where fast propagation delay (4.8 ns at 3.3 V), high noise immunity (VOLP < 0.8 V), and robust ESD protection (2000-V HBM) are critical in space-constrained TSSOP-14 layouts.
Technical Context
This IC implements four identical noninverting buffer stages, each with active-low 3-state control via dedicated OE inputs. Each buffer operates independently, enabling selective bus isolation without affecting other channels - essential for bidirectional data bus arbitration in microcontroller peripheral expansion.
Its input tolerance up to 5.5 V allows direct interfacing with legacy 5-V logic while powered from 1.65–3.6 V supplies, eliminating external level shifters. The device meets JESD 17 latch-up immunity (>250 mA) and JEDEC extended temperature qualification (–40°C to 85°C) for industrial-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 3.6 V - supports single-supply operation across LVC logic families without voltage translation circuitry. |
| tpd (Max) | 4.8 ns at VCC = 3.3 V - enables high-speed data routing in 100-MHz+ synchronous buses. |
| IOL/IOH | ±24 mA at VCC = 3 V - drives 10+ LVC loads or standard TTL inputs without fanout limitation. |
| VIH/VIL | VIL ≤ 0.8 V, VIH ≥ 2.0 V at VCC = 3.3 V - ensures noise margins >0.7 V under worst-case conditions. |
| ESD Rating | 2000-V HBM - protects against handling damage during PCB assembly and field service. |
| Operating Temp | –40°C to +85°C - qualified per JEDEC extended-temperature standards for industrial environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC125APWRE | Same functionality and pinout; commercial temp range (–40°C to 85°C) but non-EP grade - lacks enhanced DMS support and extended qualification pedigree. | Not qualified for long-life industrial deployments requiring controlled baseline and enhanced change notification. | Select SN74LVC125AIPWREP when lifecycle continuity, DMS assurance, and JEDEC-qualified reliability are mandatory. |
| SN74LVCH125APWRE | Includes bus-hold circuitry on inputs; higher ICC (10 µA vs. 5 µA typical); same VCC range and pinout. | Bus-hold eliminates need for external pullups on unused inputs but increases static current in floating-node scenarios. | Choose SN74LVC125AIPWREP when minimal quiescent current and strict adherence to legacy LVC timing specs are required. |
Compared with SN74LVC125APWRE and SN74LVCH125APWRE, the SN74LVC125AIPWREP delivers guaranteed extended-temperature qualification, controlled manufacturing baseline, and enhanced product-change visibility - making it the preferred choice for mission-critical industrial and defense programs where supply chain resilience and long-term reliability outweigh minor cost differences.

FAQ
What is the maximum operating voltage for SN74LVC125AIPWREP?
The SN74LVC125AIPWREP supports a supply voltage range of 1.65 V to 3.6 V. Its absolute maximum rating is 6.5 V on VCC, but functional operation is only guaranteed within the recommended 1.65–3.6 V range. Exceeding 3.6 V may cause parametric degradation or reliability issues, and the device is not rated for continuous operation above that limit. Always refer to the Recommended Operating Conditions table in the official datasheet for design compliance.
Does SN74LVC125AIPWREP support 5-V input signals?
Yes, SN74LVC125AIPWREP accepts input voltages up to 5.5 V regardless of VCC level - a key feature enabling seamless interfacing with 5-V TTL or CMOS devices while powered from 1.8 V or 2.5 V supplies. This eliminates external level-shifting components in mixed-voltage systems. Input clamp current is specified at ±50 mA, and VI ratings remain valid across the full operating temperature range.
What is the purpose of the OE pins on SN74LVC125AIPWREP?
The SN74LVC125AIPWREP has four independent output-enable (OE) pins - pins 1, 4, 10, and 13 - each controlling one buffer stage. When an OE pin is driven high, its corresponding Y output enters high-impedance (3-state) mode, electrically disconnecting that channel from the bus. This allows dynamic bus sharing, prevents contention in multi-driver systems, and supports power-up safety when OE is pulled high via resistor to VCC.
How does SN74LVC125AIPWREP handle power sequencing during startup?
SN74LVC125AIPWREP requires OE to be tied to VCC through a pullup resistor to ensure outputs remain in high-impedance state during power-up or power-down. The minimum resistor value depends on the driver's current-sinking capability - typically 10 kΩ suffices for most applications. This prevents bus contention or undefined states before system controllers initialize, a critical requirement in industrial systems with asynchronous power rails.
Is SN74LVC125AIPWREP RoHS compliant and lead-free?
Yes, SN74LVC125AIPWREP is RoHS compliant and features a lead-free NIPDAU (nickel/palladium/gold) terminal finish. It carries MSL Level-1 rating (unlimited floor life at ≤30°C/60% RH) and is qualified per JEDEC J-STD-020. The device is packaged in tape-and-reel format (2000 units/reel) with full traceability and conforms to TI's enhanced product change notification policy for long-term industrial deployment.
