Nexperia USA Inc. XC7SET125GV,125

Overview

XC7SET125GV,125 from Nexperia is a single-channel non-inverting 3-state bus buffer/line driver in SC-74A (SOT753) package, operating from 4.5 V to 5.5 V supply, with propagation delay ≤7.0 ns (CL = 15 pF), ±8 mA output drive, and -40 °C to +125 °C temperature range - used for bidirectional data bus isolation in industrial microcontroller I/O expansion.

For engineers reviewing the XC7SET125GV,125 datasheet, XC7SET125GV,125 pinout, XC7SET125GV,125 application, or XC7SET125GV,125 equivalent, key selection criteria include 3-state enable timing (ten ≤6.5 ns, tdis ≤11.0 ns), TTL-compatible input thresholds (VIH = 2.0 V min), low ICC (≤40 μA at 125 °C), and SOT753 footprint compatibility with space-constrained PCB layouts.

Technical Context

The XC7SET125GV,125 implements a CMOS-based non-inverting buffer with active-low 3-state control logic: OE HIGH forces Y into high-impedance OFF-state; OE LOW enables transparent A→Y signal pass-through. It uses Si-gate CMOS process for rail-to-rail output swing and symmetrical rise/fall characteristics.

Its functional behavior is defined by a two-input truth table (OE, A → Y), supporting bus sharing via tristate arbitration. Input clamping diodes and ESD protection (HBM >2000 V, CDM >1000 V) ensure robustness in noisy industrial environments without external protection components.

FAQ

What is the maximum recommended capacitive load for XC7SET125GV,125?

The datasheet specifies dynamic performance up to CL = 50 pF, with propagation delay ≤9.5 ns and disable time ≤11.0 ns at that load. Driving >50 pF may increase rise/fall times and delay variability beyond guaranteed limits, potentially violating setup/hold margins in synchronous systems. For heavier loads, consider adding series termination or selecting a higher-drive buffer.

Does XC7SET125GV,125 support mixed-voltage operation (e.g., 3.3 V input with 5 V supply)?

Yes - its TTL-compatible inputs accept VIH ≥2.0 V and VIL ≤0.8 V across VCC = 4.5–5.5 V, allowing direct connection to 3.3 V logic outputs without level shifters. However, output swing remains rail-to-rail (0 V to VCC), so downstream 3.3 V receivers require VIH ≤2.0 V compatibility or external clamping.

Is thermal pad connection required for XC7SET125GV,125 in SOT753 package?

No - the SOT753 (SC-74A) package has no exposed thermal pad. Thermal dissipation relies on copper pour under the leads and PCB trace width. The datasheet specifies Ptot = 250 mW with linear derating above 85 °C (3.8 mW/K), so keep ambient below 100 °C for continuous 5 V/8 mA operation without forced airflow.

Can OE be left floating during normal operation?

No - OE must be actively driven HIGH or LOW. Floating OE risks metastability, causing partial or intermittent output enablement and potential bus contention. Tie OE to VCC or GND via ≥10 kΩ resistor if permanently enabled/disabled; for dynamic control, route from a clean GPIO with slew-rate limiting if noise-prone.
