Product details
Overview
SN74AUP1G125 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 features active-low output enable (OE), operates from 0.8 V to 3.6 V, delivers ≤4.6 ns propagation delay at 3.3 V, supports Ioff partial-power-down mode, and drives up to ±4 mA at 3 V - used in SSDs, tablets, and wireless peripherals.
For engineers reviewing the SN74AUP1G125 datasheet, SN74AUP1G125 pinout, SN74AUP1G125 application, or SN74AUP1G125 equivalent, key selection criteria include its ultra-low ICC (0.9 µA max), 3.6-V I/O tolerance, input-disable capability for floating inputs, and DSBGA-5 (YZT) package compatibility with space-constrained PCB layouts.
Technical Context
The SN74AUP1G125 implements a non-inverting buffer with active-low 3-state control: when OE is low, Y = A; when OE is high, Y enters high-impedance state. Its balanced CMOS push-pull output enables symmetrical sourcing/sinking (±4 mA at 3 V), while standard CMOS inputs support slow-transition immunity via built-in hysteresis.
It integrates Ioff circuitry that disables all I/O paths at VCC = 0 V, preventing back-current during power sequencing. Input-disable functionality allows A to float without affecting output state, and over-voltage tolerant inputs accept signals up to 4.6 V regardless of VCC setting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC 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 |
| tpd Max | 4.6 ns at 3.3 V, CL = 5 pF - supports signal integrity in sub-100-MHz digital buses |
| ICC Max | 0.9 µA at TA = –40°C to +85°C - extends battery life in always-on portable subsystems |
| Ioff Max | 0.6 µA at VCC = 0 V - ensures safe hot-insertion and partial power-down in multi-rail systems |
| IOH/IOL | –4 mA / +4 mA at VCC = 3 V - drives multiple CMOS loads or small LEDs without external buffering |
| Input Capacitance | 1.5 pF typical - minimizes loading on high-speed source signals and reduces crosstalk |
| ESD Rating | 2000 V HBM - meets industrial handling requirements without additional protection circuitry |
Pinout & Package
SN74AUP1G125YZTR uses a 5-pin DSBGA (Die Size Ball Grid Array) package measuring 0.89 mm × 1.39 mm, optimized for ultra-compact portable PCBs. The bottom-side ball layout matches YZP/YZT variants per TI's mechanical documentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Active-low output enable input | Drives Y into high-Z when high; must be pulled up to VCC during power-up/down to guarantee Hi-Z state |
| 2 (A) | Buffer input | Accepts 0.8–3.6 V logic; supports floating input via internal disable feature |
| 3 (GND) | Ground reference | Return path for all I/O and supply currents; requires low-inductance connection to PCB ground plane |
| 4 (Y) | 3-state non-inverting output | Delivers rail-to-rail CMOS levels; sinks/sources up to ±4 mA at 3 V |
| 5 (VCC) | Positive supply | Power source for internal logic; supplies Ioff protection and enables 3.6-V tolerant inputs |
Key Features
| Feature | Design Value |
|---|---|
| Low dynamic power | Cpd = 4 pF typical at 3.3 V - reduces switching noise and EMI in dense routing environments |
| Input hysteresis | Enables robust operation with slow-rising/falling signals (e.g., RC-filtered microcontroller GPIO) |
| 3.6-V I/O tolerance | Allows interfacing with 5-V legacy peripherals while powered from 1.8-V rails - no level shifter needed |
| NanoStar™ packaging | DSBGA-5 footprint (0.89 mm × 1.39 mm) saves >60% board area vs. SOT-23 - critical for wearables and hearing aids |
| Overshoot/undershoot control | <10% of VCC - eliminates need for series termination resistors on short traces |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G125DBVR | Wider VCC range (1.65–5.5 V); higher ICC (10 µA typ); no Ioff; 5.5-V tolerant I/O | Preferred where 5-V interface compatibility is required but partial-power-down is not needed | Select when system uses 5-V peripherals and does not require hot-swap safety |
| NC7SZ125M5X | Lower drive (±2.6 mA at 3.3 V); smaller SC70-5 package; no Ioff; 3.6-V tolerant I/O | Better suited for cost-sensitive, low-drive applications with minimal power sequencing constraints | Choose for budget-constrained designs where 4-mA drive and Ioff are non-critical |
Compared with SN74LVC1G125DBVR and NC7SZ125M5X, SN74AUP1G125YZTR uniquely combines ultra-low ICC (0.9 µA), Ioff-enabled safe power-down, and DSBGA-5 miniaturization - making it optimal for battery-powered devices requiring zero-standby leakage and space efficiency.

FAQ
What is the recommended pull-up resistor value for OE on SN74AUP1G125YZTR?
The OE pin must be tied to VCC through a pull-up resistor to ensure high-impedance state during power-up/down. TI specifies minimum resistance based on driver sink capability: for typical use, 10 kΩ to 100 kΩ is sufficient. Lower values improve noise immunity but increase static current; higher values reduce current but risk slower edge rates. Always verify against actual board-level noise and sequencing requirements in your SN74AUP1G125YZTR design.
Does SN74AUP1G125YZTR support mixed-voltage operation between 1.8-V and 3.3-V domains?
Yes. SN74AUP1G125YZTR accepts input voltages up to 4.6 V independent of VCC, enabling reliable level translation from 3.3-V or 5-V sources into 1.8-V systems. Its 3.6-V I/O tolerance and 0.8–3.6 V VCC range allow bidirectional interfacing without external level shifters - confirmed in TI's SCES595N datasheet Section 6.3 and 8.3.5.
Can SN74AUP1G125YZTR drive an LED directly?
Yes. SN74AUP1G125YZTR delivers ±4 mA output drive at 3 V, sufficient to illuminate low-current indicator LEDs (e.g., 2-mA green/red LEDs). For higher-brightness or multi-LED configurations, add a current-limiting resistor calculated using VOL and forward voltage. Do not exceed absolute maximum ratings: continuous output current is ±20 mA, but sustained >4 mA may require thermal validation in your SN74AUP1G125YZTR layout.
What is the significance of Ioff in SN74AUP1G125YZTR for system power management?
Ioff ensures all inputs and outputs enter high-impedance state when VCC = 0 V, limiting leakage to ≤0.6 µA. This prevents back-current from live buses into unpowered sections - critical for hot-plug, battery-backed subsystems, and multi-rail power sequencing. In SN74AUP1G125YZTR, Ioff enables safe partial-power-down without external isolation switches or diodes.
How does the input-disable feature of SN74AUP1G125YZTR improve system reliability?
The input-disable feature allows the A input to float without causing undefined output states or increased ICC. This eliminates need for external pull resistors on unused or tri-stated MCU GPIOs, reducing BOM cost and PCB space. In SN74AUP1G125YZTR, it also suppresses oscillation from unterminated traces - verified by TI's "Implications of Slow or Floating CMOS Inputs" application report SCBA004.
