Product details
Overview
SN74AUP1G125YFPR from Texas Instruments is a single low-power bus buffer gate with 3-state output, designed for signal isolation and level translation in portable electronics. It operates across 0.8 V to 3.6 V supply, delivers ≤4.6 ns propagation delay at 3.3 V, supports Ioff partial-power-down mode, and features 3.6-V I/O tolerance - enabling use in mixed-voltage SSD, tablet, and wireless peripheral interfaces.
For engineers reviewing the SN74AUP1G125YFPR datasheet, SN74AUP1G125YFPR pinout, SN74AUP1G125YFPR application, or SN74AUP1G125YFPR equivalent, key selection criteria include its ultra-low ICC (0.9 µA max), 1.5 pF input capacitance, active-low OE control, DSBGA-6 package footprint (0.76 mm × 1.16 mm), and compatibility with battery-powered systems requiring high noise immunity and floating-input resilience.
Technical Context
The SN74AUP1G125YFPR implements a non-inverting buffer (Y = A) with active-low 3-state enable (OE). Its balanced CMOS push-pull output drives ±4 mA at 3 V while maintaining rail-to-rail VOH/VOL performance under load. The device uses standard CMOS inputs with hysteresis-enhanced noise immunity and includes clamp diodes for ESD protection.
Ioff functionality ensures all I/O pins enter high-impedance state when VCC = 0 V, preventing back-current during power sequencing. Input-disable capability allows A and OE to float without causing undefined logic states - critical for hot-plug and sleep-mode operation in portable audio docks and SSD controllers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 0.8 V to 3.6 V - enables direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters |
| Max Propagation Delay | 4.6 ns at 3.3 V, CL = 5 pF - supports signal integrity up to ~100 MHz in short-trace applications |
| Static Current (ICC) | 0.9 µA maximum at TA = 85°C - extends battery life in always-on sensor or standby circuits |
| Input Capacitance (CI) | 1.5 pF typical - minimizes loading on high-impedance source nodes like MCU GPIOs or crystal oscillator outputs |
| Ioff Leakage | 0.6 µA maximum at TA = 85°C - ensures safe isolation during partial power-down in multi-rail systems |
| Output Drive | ±4 mA at 3 V - sufficient to drive multiple CMOS loads or low-current LEDs without external buffers |
| I/O Tolerance | 3.6-V tolerant inputs - allows interfacing with 5-V legacy peripherals while powered from 3.3 V or lower |
Pinout & Package
SN74AUP1G125YFPR is packaged in a 6-pin DSBGA (Die Size Ball Grid Array) with 0.4-mm pitch, body size 0.76 mm × 1.16 mm, and bottom-side ball layout. This ultra-compact package targets space-constrained portable designs including wireless headsets and SSD modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Input | Non-inverting data input; accepts 0.8–3.6 V logic levels; supports floating condition via input-disable feature |
| OE | Input (active low) | Output-enable control; must be pulled high via resistor during power-up/down to guarantee Hi-Z state |
| Y | Output | 3-state buffered output; drives high/low when OE = L; enters Hi-Z when OE = H |
| VCC | Power supply | Primary supply pin; powers internal logic and output stage; range 0.8–3.6 V |
| GND | Ground | Reference return path for all signals and supply current |
| N.C. | No connection | Unused ball; left unconnected per TI specification; no internal bond or circuitry |
Key Features
| Feature | Design Value |
|---|---|
| Low dynamic power (Cpd = 4 pF) | Reduces switching noise and heat generation in high-frequency data paths such as SSD command buses |
| Input hysteresis | Improves noise margin against slow-rising signals from mechanical switches or long PCB traces in PDA interfaces |
| Low overshoot/undershoot (<10% VCC) | Maintains signal integrity on compact layouts without added termination resistors in tablet display timing lines |
| 3.6-V I/O tolerant inputs | Enables voltage-level translation from 5-V sensors or legacy controllers into 1.8-V or 2.5-V SoC domains |
| Ioff partial-power-down support | Prevents backfeeding between powered-down and active subsystems in modular telecom AC/DC supplies |
Applications

IC Role / Device Role / Timing Role: Low-jitter, low-capacitance buffer isolating processor GPIOs from panel-side EMI-sensitive traces. Use Value: 1.5 pF CI and <10% VCC overshoot minimize signal distortion; DSBGA-6 footprint saves board area near narrow bezel edges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G125YZPR | Wider VCC range (1.65–5.5 V); higher ICC (10 µA typ); no Ioff; 5-pin DSBGA | Supports 5-V legacy systems but lacks partial-power-down safety for multi-rail SSDs | Choose when interfacing with 5-V peripherals and Ioff is not required |
| NC7SZ125P5X | Smaller SC-70-5 package; 1.65–5.5 V operation; Cpd = 5.5 pF; no Ioff; 3.6-V tolerant inputs | Better for cost-sensitive consumer audio docks where space is less constrained than in SSDs | Choose for legacy 3.3-V-only designs needing lowest BOM cost and wide temp range (−40°C to +85°C) |
Compared with SN74AUP1G125YFPR, SN74LVC1G125YZPR offers higher voltage flexibility but sacrifices Ioff protection and ultra-low ICC, while NC7SZ125P5X trades DSBGA miniaturization and Ioff for broader voltage support and higher dynamic power - making SN74AUP1G125YFPR optimal for battery-critical, space-constrained, multi-rail portable systems.

FAQ
What is the function of the OE pin on the SN74AUP1G125YFPR?
The OE (output enable) pin on the SN74AUP1G125YFPR is an active-low control input that places the Y output in high-impedance (Hi-Z) state when driven high. When OE is low, the device performs a non-inverting buffer function (Y = A). To ensure reliable Hi-Z during power-up/down, TI specifies tying OE to VCC via a pullup resistor - minimum value determined by driver sink capability. This behavior is confirmed in the Function Table and Pin Functions section of the SCES595N datasheet.
Does the SN74AUP1G125YFPR support partial power-down operation?
Yes, the SN74AUP1G125YFPR supports partial power-down via its Ioff feature. When VCC = 0 V, both input and output pins enter a high-impedance state with leakage limited to 0.6 µA max at 85°C. This prevents current backflow from live buses into the unpowered device - a critical requirement in multi-rail systems like telecom AC/DC supplies and SSDs with independent power domains. Ioff is explicitly specified in Section 6.5 and 6.6 of the datasheet.
What package type is used for the SN74AUP1G125YFPR?
The SN74AUP1G125YFPR uses a 6-pin DSBGA (Die Size Ball Grid Array) package with nominal dimensions of 0.76 mm × 1.16 mm and 0.4-mm ball pitch. This ultra-compact, bottom-terminal package is optimized for space-constrained portable applications including wireless headsets and client SSD modules. Pin configuration and mechanical drawings are documented in the "Pin Configuration and Functions" section (page 3) of the SCES595N datasheet.
Can the SN74AUP1G125YFPR interface with 5-V logic signals?
The SN74AUP1G125YFPR supports 3.6-V tolerant inputs - meaning it can safely accept input voltages up to 3.6 V regardless of VCC level (0.8–3.6 V), but it does not support direct 5-V input signals. Applying >3.6 V violates Absolute Maximum Ratings and risks permanent damage. For 5-V to lower-voltage translation, a dedicated level shifter or a 5-V tolerant alternative like SN74LVC1G125 is required. This limit is defined in Section 6.1 (Absolute Maximum Ratings) of the datasheet.
What is the maximum operating temperature range for the SN74AUP1G125YFPR?
The SN74AUP1G125YFPR is rated for operation across –40°C to +85°C ambient temperature, as specified in Section 6.3 (Recommended Operating Conditions) of the SCES595N datasheet. All electrical characteristics - including VOH, VOL, ICC, and tpd - are guaranteed across this full industrial temperature range. Thermal metrics (RθJA, RθJB) are also provided for each package variant, confirming thermal viability in sealed portable enclosures.
