Product details
Overview
XC7WH126DP,125 from Nexperia is a dual non-inverting 3-state buffer/line driver in TSSOP8 (SOT505-2) package, designed for bidirectional bus interfacing and signal isolation in high-speed digital systems. It operates across -40 °C to +125 °C, supports 2.0–5.5 V supply, delivers ≤7.0 ns propagation delay at 3.3 V/15 pF, and features CMOS-compatible inputs with symmetrical output impedance.
For engineers reviewing the XC7WH126DP,125 datasheet, XC7WH126DP,125 pinout, XC7WH126DP,125 application, or XC7WH126DP,125 equivalent, key selection criteria include 3-state enable timing (≤9.5 ns disable time), rail-to-rail input voltage tolerance (−0.5 V to VCC+0.5 V), low ICC (≤40 μA), and industrial temperature range compliance.
Technical Context
The XC7WH126DP implements two independent non-inverting buffers, each with active-HIGH output enable (1OE, 2OE) controlling high-impedance OFF-state on corresponding outputs (1Y, 2Y). Inputs (1A, 2A) accept standard CMOS logic levels, and outputs drive capacitive loads up to 50 pF with matched rise/fall times.
Its architecture enables bus-hold-free signal routing in mixed-voltage systems: VCC defines logic thresholds (VIH = 3.85 V min at VCC = 5.5 V; VIL = 1.65 V max), while static current draw remains below 10 μA over full temperature range, supporting low-power standby modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VCC) | 2.0–5.5 V - Enables interoperability with 2.5 V, 3.3 V, and 5 V logic families without level shifters. |
| Propagation Delay (tpd) | ≤7.0 ns @ 3.3 V/15 pF - Supports >100 MHz data rates in point-to-point or lightly loaded bus applications. |
| Enable/Disable Time (ten/tdis) | ≤9.5 ns @ 3.3 V/50 pF - Ensures clean bus arbitration with minimal contention window during state transitions. |
| Output Drive Strength | ±8 mA @ VCC = 4.5 V - Sufficient to drive 50 Ω transmission lines or multiple CMOS inputs (fan-out ≥20). |
| Input Leakage Current | ≤2.0 μA @ −40 °C to +125 °C - Guarantees stable enable/disable control under extended thermal stress without pull-up/down burden. |
| ESD Robustness | HBM >2000 V, CDM >1000 V - Meets IEC 61000-4-2 Level 3 requirements for board-level handling and system integration. |
Pinout & Package
TSSOP8 package (SOT505-2): plastic thin shrink small outline, 8-pin, 3 mm body width, 0.65 mm pitch, lead length 0.5 mm, rated for −40 °C to +125 °C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7 (1OE, 2OE) | Active-HIGH output enable | Drives respective output (1Y or 2Y) into high-Z when LOW; requires no external pull-down for default disabled state. |
| 2, 5 (1A, 2A) | Data input | CMOS-compatible input accepting VI from GND to VCC; 1.5 pF typical input capacitance minimizes loading on driving source. |
| 3, 6 (2Y, 1Y) | Data output | Non-inverting buffered output with symmetrical VOH/VOL and matched tPLH/tPHL for glitch-free signal replication. |
| 4 | GND | Signal and power reference plane; decoupling capacitor must be placed adjacent to Pin 4 and Pin 8 for noise suppression. |
| 8 | VCC | Primary supply rail; supports bypassing with 100 nF ceramic capacitor directly between Pins 4 and 8 to maintain switching stability. |
Key Features
| Feature | Design Value |
|---|---|
| Symmetrical output impedance | Enables matched rise/fall times (tr/tf ≤3 ns) and reduces signal distortion on mismatched PCB traces. |
| Balanced propagation delays | Ensures <100 ps skew between channels, critical for parallel data bus integrity and clock distribution buffering. |
| High noise immunity | VIH/VIL margins exceed 30% of VCC across full temperature range, rejecting EMI-induced false triggering in noisy industrial environments. |
| Low power dissipation | ICC ≤40 μA at VCC = 5.5 V enables use in always-on subsystems without thermal derating concerns. |

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 |
|---|---|---|---|
| SN74LVC2G126DCUR | Same TSSOP8 footprint but lower VCC range (1.65–5.5 V); tpd = 3.7 ns @ 3.3 V/50 pF (faster), ICC = 10 μA (lower). | Optimized for battery-powered portable test gear requiring ultra-low quiescent current and sub-4 ns timing. | Select when operating below 2.0 V or needing tighter timing budgets; verify 1.65 V VIH compatibility with driving source. |
| 74AUP2G126GM,132 | VCC = 0.8–3.6 V only; tpd = 10.3 ns @ 3.0 V/50 pF (slower); ICC = 0.5 μA (ultra-low); −40 °C to +125 °C rated. | Targeted at energy-harvesting sensor nodes where sub-μA standby dominates design priority over speed. | Choose for sub-1 V logic domains or extreme low-power sleep modes; not suitable for 5 V systems or >50 MHz operation. |
Compared with SN74LVC2G126DCUR, XC7WH126DP,125 offers higher VCC tolerance (up to 5.5 V) and better noise margin at 5 V operation, while 74AUP2G126GM,132 trades speed for nanoampere-level ICC-making XC7WH126DP,125 the balanced choice for industrial 3.3/5 V mixed-signal interfaces.

FAQ
What is the maximum recommended load capacitance for reliable operation?
The datasheet specifies dynamic performance up to 50 pF load capacitance, with propagation delay increasing linearly beyond that value. At CL = 50 pF and VCC = 3.3 V, tpd remains ≤7.0 ns and tdis ≤9.5 ns-ensuring timing closure in most PCB interconnect scenarios. Exceeding 50 pF may require layout optimization or local termination.
Does XC7WH126DP,125 support mixed-voltage operation between input and output sides?
No-it is a single-supply device with all I/O referenced to the same VCC rail. Input voltage range is −0.5 V to VCC + 0.5 V, and output swing is rail-to-rail within VCC/GND. For true level translation, a dedicated dual-supply translator like NXH0108UK is required.
How does the 3-state enable timing affect bus arbitration in multi-driver systems?
With ten ≤9.5 ns and tdis ≤9.5 ns at 3.3 V/50 pF, the device ensures rapid transition between driven and high-Z states-minimizing bus contention windows to under 20 ns. This allows deterministic arbitration in systems with ≤50 ns clock periods, such as 20 MHz SPI or legacy parallel address/data buses.
Is thermal derating required for continuous operation at +125 °C ambient?
Yes-the TSSOP8 package (SOT505-2) derates total power dissipation linearly at 4.6 mW/K above +96 °C. At +125 °C, Ptot drops to ~120 mW. With typical ICC ≤40 μA and IO ≤8 mA, power dissipation stays well below this limit-no external heatsinking is needed for standard logic-level loading.
