Product details
Overview
74AUP2G125GT/S500115 from NXP Semiconductors is a dual non-inverting 3-state buffer/line driver in XSON8 package (SOT833-1), operating from 0.8 V to 3.6 V supply, with Schmitt-trigger inputs, IOFF partial power-down support, and −40 °C to +125 °C temperature range-used for level-shifting and bus isolation in ultra-low-power portable and IoT interfaces.
For engineers reviewing the 74AUP2G125GT/S500115 datasheet, 74AUP2G125GT/S500115 pinout, 74AUP2G125GT/S500115 application, or 74AUP2G125GT/S500115 equivalent, this page delivers verified pin functions, real-world timing values at multiple VCC/load conditions, IOFF leakage specs, Schmitt-trigger noise immunity thresholds, and direct alternatives for low-voltage bus buffering designs.
Technical Context
This device implements two independent non-inverting buffers, each with active-low 3-state output enable (nOE). Each channel features Schmitt-trigger input hysteresis across the full 0.8 V–3.6 V VCC range, enabling robust operation with slow-rising signals and high noise immunity.
The IOFF circuitry actively disables outputs during power-down (VCC = 0 V), limiting backflow current to ±0.75 µA, while input-disable functionality allows safe floating of data inputs when nOE is HIGH-critical for hot-swap and multi-drop bus architectures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 0.8 V to 3.6 V - supports single-supply operation across battery-powered, 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains |
| Propagation delay (tpd) | 1.4 ns (min) to 4.4 ns (max) at VCC = 3.0–3.6 V, CL = 5 pF - enables sub-5 ns signal routing in compact timing-critical paths |
| IOFF leakage current | ±0.75 µA max at VCC = 0 V - prevents damaging backflow during partial power-down in mixed-voltage systems |
| Input hysteresis | Integrated Schmitt-trigger action - ensures clean switching with slow edges and rejects noise up to 30 % of VCC |
| Static supply current (ICC) | 1.4 µA max at −40 °C to +125 °C - sustains ultra-low quiescent power in always-on sensor nodes |
| ESD protection | HBM > 5000 V, MM > 200 V, CDM > 1000 V - meets industrial handling requirements without external protection |
| Operating temperature | −40 °C to +125 °C - qualified for under-hood automotive, industrial control, and extended-range embedded applications |
Pinout & Package
XSON8 plastic extremely thin small outline package (SOT833-1); no leads; 8 terminals; body dimensions 1.0 mm × 1.95 mm × 0.5 mm; thermal pad optional; pin 1 index in lower-left corner below marking code "p25".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1Y (Buffer 1 output) | Non-inverting buffered output; high-impedance when 1OE = HIGH |
| 2 | 2OE (Buffer 2 output enable) | Active-LOW enable for second buffer; disables 2Y and disables 2A input when HIGH |
| 3 | VCC | Positive supply rail; powers both buffers and internal logic; decoupling required within 2 mm |
| 4 | 2A (Buffer 2 input) | Data input for second buffer; Schmitt-triggered; accepts up to 3.6 V regardless of VCC |
| 5 | 2Y (Buffer 2 output) | Non-inverting buffered output; high-impedance when 2OE = HIGH |
| 6 | 1A (Buffer 1 input) | Data input for first buffer; Schmitt-triggered; tolerant to slow edges and noise |
| 7 | 1OE (Buffer 1 output enable) | Active-LOW enable for first buffer; disables 1Y and disables 1A input when HIGH |
| 8 | GND | Ground reference; must be connected to system ground plane with low-inductance path |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (0.8 V–3.6 V) | Enables interoperability between legacy 1.2 V logic and modern 3.3 V I/O without level shifters |
| Input-disable on nOE HIGH | Prevents unintended input loading and reduces dynamic power when buffers are disabled |
| IOFF partial power-down | Blocks current flow through powered-down device, protecting downstream circuits during brown-out |
| Schmitt-trigger inputs | Guarantees monotonic switching with rise/fall times up to 200 ns/V - eliminates contact bounce or EMI-induced glitches |
| Ultra-low ICC (1.4 µA max) | Reduces battery drain in always-on wearable and sensor edge devices over multi-year deployments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AUP2G125DCUR | VSSOP8 package (2.3 mm width); higher thermal resistance; same electrical specs and pinout mapping | Better suited for prototyping or manual soldering; less space-constrained layouts | Select when board layout allows 2.3 mm body width and hand-soldering is required |
| 74LVC2G125GW,125 | No Schmitt-trigger inputs; IOFF not specified; higher ICC (10 µA typical); same XSON8 footprint | Limited noise immunity on slow signals; unsuitable for partial power-down systems | Choose only if Schmitt input and IOFF are not required and cost is primary constraint |
Compared with SN74AUP2G125DCUR and 74LVC2G125GW,125, the 74AUP2G125GT/S500115 uniquely combines ultra-low ICC (<1.4 µA), guaranteed Schmitt-trigger hysteresis, and IOFF compliance in the smallest XSON8 variant (1.0 × 1.95 mm), making it optimal for miniaturized, battery-sensitive, and thermally constrained designs.

FAQ
What is the maximum allowable supply voltage for the 74AUP2G125GT/S500115?
The absolute maximum supply voltage (VCC) for the 74AUP2G125GT/S500115 is +4.6 V, but the recommended operating range is strictly 0.8 V to 3.6 V. Exceeding 3.6 V may cause parametric degradation or reliability issues, even if within absolute maximum ratings. All timing, drive strength, and leakage specifications are guaranteed only within the 0.8 V–3.6 V range per the official NXP datasheet Rev. 10.
Does the 74AUP2G125GT/S500115 support true bidirectional signal routing?
No, the 74AUP2G125GT/S500115 is a unidirectional non-inverting buffer - it does not support automatic direction sensing or data flow reversal. Each channel (1A→1Y and 2A→2Y) operates strictly in one direction. Bidirectional operation requires external control logic or a dedicated transceiver like the 74AUP2G80 or 74LVC2T45, which the 74AUP2G125GT/S500115 does not provide.
How does the input-disable feature function in the 74AUP2G125GT/S500115?
When either 1OE or 2OE is driven HIGH, the corresponding input (1A or 2A) is internally disconnected from the buffer core, allowing that input to float without drawing leakage current or affecting adjacent signals. This is confirmed in Section 1 and Table 4 of the datasheet, where "X" denotes "don't care" for nA when nOE = H - meaning the input is electrically isolated, not just ignored.
Can the 74AUP2G125GT/S500115 be used with 5 V-tolerant inputs?
Yes - the 74AUP2G125GT/S500115 inputs accept voltages up to 3.6 V regardless of VCC level, as explicitly stated in Section 2 ("Inputs accept voltages up to 3.6 V"). However, it is not 5 V-tolerant: applying >3.6 V risks damage or undefined behavior. For true 5 V-tolerant interfacing, a different device such as the 74LVC2G125 or level-shifter IC is required.
What is the typical propagation delay of the 74AUP2G125GT/S500115 at 1.8 V and 15 pF load?
At VCC = 1.65 V to 1.95 V and CL = 15 pF, the typical propagation delay (tpd) of the 74AUP2G125GT/S500115 is 4.3 ns (25 °C) and up to 8.8 ns at +125 °C, per Table 8. This value applies to both tPLH and tPHL transitions and reflects actual measured performance-not worst-case max - enabling accurate timing margin analysis in 1.8 V systems.
