Nexperia USA Inc. 74LVC1G125GM,132

Overview

74LVC1G125GM,132 from Nexperia is a single 3-state bus buffer/line driver with Schmitt-trigger inputs, designed for level translation between 1.65 V–5.5 V logic domains. It provides ±24 mA output drive at 3.0 V, supports partial power-down via IOFF, and operates from –40 °C to +125 °C in the XSON6 (SOT886) package. It enables reliable signal routing in mixed-voltage I/O interfaces of industrial microcontroller peripherals.

For engineers reviewing the 74LVC1G125GM,132 datasheet, 74LVC1G125GM,132 pinout, 74LVC1G125GM,132 application, or 74LVC1G125GM,132 equivalent, key selection criteria include its 3-state control timing (tdis ≤ 6 ns at 3.3 V), overvoltage-tolerant 5.5 V inputs, IOFF-enabled backflow prevention during power sequencing, and thermal performance in 1.0 × 1.45 × 0.5 mm XSON6 packaging.

Technical Context

This device implements a non-inverting 3-state buffer with active-low output enable (OE). Its Schmitt-trigger inputs accept slow-rising signals and tolerate noise up to 0.4 V hysteresis (typical), while the IOFF circuit disables outputs and blocks current flow when VCC = 0 V - critical for hot-swap and multi-rail power sequencing.

It complies with JEDEC standards JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), JESD8C (2.7–3.6 V), and JESD36 (4.5–5.5 V), ensuring interoperability across legacy and modern logic families including TTL and LVTTL. Propagation delay ranges from 0.5 ns (VCC = 4.5–5.5 V) to 10.5 ns (VCC = 1.65–1.95 V) over temperature.

FAQ

What is the maximum allowable input voltage when VCC = 1.65 V?

The 74LVC1G125GM,132 accepts input voltages up to 5.5 V regardless of VCC level, as confirmed in Table 5 (Limiting Values) and Section 1. General description. This overvoltage tolerance enables safe interfacing with 5 V sources while operating from 1.65 V, eliminating external clamping components in mixed-voltage designs.

Does this device support hot-swap operation?

Yes - the integrated IOFF circuit actively disables outputs and blocks backflow current when VCC = 0 V, as specified in Section 1 and Table 7 (Static Characteristics). This feature meets hot-swap requirements in modular systems where boards may be inserted or removed while other rails remain powered.

How does the Schmitt-trigger input improve noise immunity?

The Schmitt-trigger action provides ~0.4 V typical hysteresis between VIH and VIL thresholds, rejecting noise spikes and slow-rising edges that could cause metastability or double-clocking. This is especially valuable in long-trace industrial wiring or electrically noisy environments like motor drives or power supplies.

Can the n.c. pin on the XSON6 package be grounded?

No - the n.c. (pin 5) is internally unconnected and must remain floating per Nexperia's layout guidance in Section 6.1. Grounding it may induce parasitic coupling or violate package thermal characteristics; the recommended practice is to leave it unconnected or cover with solder mask only.
