Product details
Overview
XC7SH125GV,125 from Nexperia is a single-channel non-inverting 3-state bus buffer/line driver in SC-74A (SOT753) package, operating from 2.0 V to 5.5 V supply, with propagation delay as low as 3.4 ns at 5 V/15 pF, ±8 mA output drive, and guaranteed operation from –40 °C to +125 °C - used for bidirectional data bus isolation in industrial microcontroller peripheral interfaces.
For engineers reviewing the XC7SH125GV,125 datasheet, XC7SH125GV,125 pinout, XC7SH125GV,125 application, or XC7SH125GV,125 equivalent, this page delivers verified functional behavior, thermal derating curves, static/dynamic electrical specs across temperature, ESD robustness (HBM >2000 V), and real-world use cases in bus arbitration and level-shifting I/O expansion.
Technical Context
The XC7SH125GV,125 implements a CMOS-based non-inverting buffer with active-low 3-state control: OE = LOW enables Y = A; OE = HIGH forces Y into high-impedance state. It uses Si-gate CMOS technology with symmetrical output impedance and balanced tPLH/tPHL delays.
Its input accepts standard CMOS voltage levels (VIH ≥ 3.85 V @ VCC = 5.5 V; VIL ≤ 1.65 V), supports rail-to-rail output swing (VOH ≥ 3.94 V @ IO = –8 mA, VCC = 4.5 V; VOL ≤ 0.36 V @ IO = 8 mA), and maintains stable performance under fast edge rates (Δt/ΔV down to 20 ns/V at 5 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VCC) | 2.0 V to 5.5 V - supports dual-rail systems and legacy 3.3 V / modern 5 V logic domains. |
| Propagation Delay (tpd) | 3.4 ns typical @ VCC = 5.0 V, CL = 15 pF - enables sub-100 MHz bus timing margins in compact PCB layouts. |
| Output Drive Strength | ±8 mA @ VCC = 4.5 V - sufficient to drive 15–50 pF loads across multiple CMOS inputs without signal degradation. |
| 3-State Enable/Disable Time | ten = 3.6 ns, tdis = 4.1 ns typical @ VCC = 5.0 V, CL = 15 pF - ensures clean bus turnaround during multi-master arbitration. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood industrial control units and motor drive interface modules. |
| ESD Robustness | HBM >2000 V, CDM >1000 V - eliminates need for external protection in board-level ESD zones. |
| Input Capacitance (CI) | 1.5 pF typical - minimizes capacitive loading on upstream drivers and preserves signal integrity in high-speed routing. |
Pinout & Package
XC7SH125GV,125 is housed in SC-74A (SOT753) plastic surface-mounted package: 5-terminal, 1.25 mm body width, 0.65 mm lead pitch, 1.3 mm × 2.2 mm footprint, 0.95 mm height - optimized for space-constrained industrial PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OE (Output Enable) | Active-HIGH enable control: HIGH → Y = high-Z; LOW → Y = A - enables shared-bus contention management. |
| 2 | A (Data Input) | CMOS-compatible input accepting 0–VCC logic levels - directly interfaces with MCU GPIO or FPGA I/O banks. |
| 3 | GND | Signal reference and return path for all internal logic - must be low-inductance connection to minimize ground bounce. |
| 4 | Y (Data Output) | Non-inverting buffered output with 3-state capability - drives downstream logic or bus traces with controlled edge rates. |
| 5 | VCC | Positive supply rail - requires local 100 nF ceramic decoupling within 3 mm of pin for stable high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| Symmetrical output impedance | Enables matched rise/fall times (tPLH ≈ tPHL), reducing jitter and EMI in clock-synchronous bus transfers. |
| Balanced propagation delays | tpd variation < 1.5 ns across –40 °C to +125 °C - ensures deterministic timing in real-time control loops. |
| Low power dissipation | ICC ≤ 1.0 μA typical @ VCC = 5.5 V - extends battery life in always-on sensor interface nodes. |
| High noise immunity | VIH/VIL margins > 0.7 V @ VCC = 3.3 V - rejects coupled transients in noisy motor-drive or power-conversion environments. |
| Multiple package options | SOT753 (SC-74A) offers proven manufacturability and rework compatibility vs. TSSOP5/XSON6 alternatives. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G125DBVR | TI part in SOT-23-5; identical function but higher ICC (10 μA max) and wider VCC range (1.65–5.5 V); no CDM spec published. | Preferred where 1.65 V logic compatibility is required; less suitable for ultra-low-power metering nodes due to higher quiescent current. | Select when interfacing with 1.8 V FPGAs or low-VCC ASICs; verify CDM robustness separately if handling-sensitive environments apply. |
| 74LVC1G125GW,125 | Nexperia's TSSOP5 variant (SOT353-1); same electrical specs but 20 % larger footprint and 0.65 mm pitch - easier rework but higher board cost. | Better suited for prototyping or low-volume repair where hand-soldering reliability is prioritized over density. | Choose for NPI builds or field-serviceable designs; avoid in high-density industrial controllers where SC-74A saves 30 % area. |
Compared with SN74LVC1G125DBVR and 74LVC1G125GW,125, the XC7SH125GV,125 delivers lowest system-level cost in high-volume industrial designs via smaller SC-74A footprint, lowest ICC (1.0 μA), and documented CDM >1000 V - critical for automated assembly lines with charged-device risk.

FAQ
What is the maximum recommended load capacitance for reliable 100 MHz operation?
The XC7SH125GV,125 supports up to 50 pF load capacitance with guaranteed timing (tpd ≤ 7.5 ns @ VCC = 5.0 V). For 100 MHz toggle rates, total node capacitance-including PCB trace, via, and downstream input-must remain ≤45 pF to maintain <10 % duty-cycle distortion and meet setup/hold margins.
Can OE be left floating in circuit design?
No. OE must be actively driven HIGH or LOW; floating OE risks metastability and partial turn-on of output FETs, causing shoot-through current and unpredictable bus states. A 10 kΩ pull-down resistor to GND is recommended for default-disabled operation.
Does XC7SH125GV,125 support mixed-voltage operation (e.g., 3.3 V input driving 5 V output)?
No. The device is not level-translating: VIH/VIL thresholds scale with VCC, and Y cannot exceed VCC. To interface 3.3 V logic with 5 V buses, use dedicated level translators like NXSLV1T240 or add external resistive dividers with appropriate timing analysis.
How does thermal derating affect power dissipation at 125 °C ambient?
For the SC-74A (SOT753) package, Ptot derates linearly at 3.8 mW/K above +85 °C. At +125 °C ambient, maximum allowable power drops to 250 mW − (40 K × 3.8 mW/K) = 98 mW - limiting continuous output current to ~6.5 mA at 5 V to stay within safe junction temperature.
