Nexperia USA Inc. XC7SH125GF,132

Overview

XC7SH125GF,132 from Nexperia is a single-channel non-inverting 3-state bus buffer/line driver in SOT891 package, operating from 2.0 V to 5.5 V supply, with propagation delay as low as 3.4 ns (VCC = 5.0 V, 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 XC7SH125GF,132 datasheet, XC7SH125GF,132 pinout, XC7SH125GF,132 application, or XC7SH125GF,132 equivalent, this page delivers verified functional behavior, validated pin mapping for SOT891, real-world timing constraints under load, and direct substitution guidance against industry-standard alternatives.

Technical Context

The XC7SH125GF,132 implements a CMOS-based non-inverting buffer with active-low 3-state control via OE input; its output enters high-impedance state when OE is HIGH, enabling bus sharing without contention. It supports rail-to-rail input logic levels compatible with both 3.3 V and 5 V systems.

Dynamic performance is defined by three key timing parameters: tpd (A→Y propagation delay), ten (OE→Y enable time), and tdis (OE→Y disable time), all specified across VCC = 3.0–5.5 V and CL = 15/50 pF loads, with guaranteed max values up to 11.5 ns at 125 °C ambient.

FAQ

What is the function of the OE pin on XC7SH125GF,132?

The OE (output enable) pin is an active-HIGH control input that places the Y output in high-impedance (OFF) state when driven HIGH. When OE is LOW, the device operates as a non-inverting buffer passing signal from A to Y. No internal pull-up or pull-down is integrated - external biasing is required for defined startup state.

Does XC7SH125GF,132 support mixed-voltage operation between 3.3 V and 5 V domains?

Yes - the device accepts input voltages up to VCC (max 5.5 V) and maintains valid VIH/VIL thresholds across 2.0–5.5 V supply range. With VCC = 5.0 V, VIH = 3.85 V and VIL = 1.65 V provide >0.7 V noise margin, enabling direct connection to both 3.3 V and 5 V logic without level shifters.

Is XC7SH125GF,132 qualified for automotive applications?

No - XC7SH125GF,132 is not AEC-Q100 qualified and carries no automotive qualification statement in its official Nexperia documentation. It is rated for industrial use (-40 °C to +125 °C), but lacks automotive-specific stress testing, failure rate reporting, or PPAP documentation required for vehicle systems.

How does thermal derating apply to XC7SH125GF,132 in SOT891 package?

For SOT891, total power dissipation (Ptot) is rated 250 mW at Tamb ≤ 74 °C and derates linearly at 3.3 mW/K above that temperature. At 125 °C ambient, maximum allowable Ptot drops to 83 mW - requiring careful layout with thermal vias to the inner ground plane to maintain junction temperature below 150 °C.
