Nexperia USA Inc. 74LVC1G240GM,115

Overview

74LVC1G240GM,115 from Nexperia is a single-channel inverting buffer/line driver with 3-state output and output enable (OE) control, operating from 1.65 V to 5.5 V supply, delivering ±24 mA drive at 3.0 V, and rated for -40 °C to +125 °C. It features Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, and 5.5 V-tolerant inputs-enabling level translation between 3.3 V and 5 V systems in industrial I/O expansion and sensor interface circuits.

For engineers reviewing the 74LVC1G240GM,115 datasheet, 74LVC1G240GM,115 pinout, 74LVC1G240GM,115 application, or 74LVC1G240GM,115 equivalent, key selection criteria include 3-state timing (enable/disable delays ≤ 7 ns), IOFF-enabled safe power sequencing, input overvoltage tolerance, rail-to-rail output swing, and XSON6 package thermal performance in space-constrained PCB layouts.

Technical Context

This device implements a single inverting logic gate with active-low output enable, where OE HIGH forces Y into high-impedance state-enabling bus sharing and dynamic load isolation. Its Schmitt-trigger inputs accept slow-rising signals (≤10 ns/V transition rate) without oscillation, and IOFF circuitry actively disables outputs during VCC = 0 V, blocking backflow current.

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 mixed-voltage logic families. Static parameters-including VIH/VIL thresholds, VOL/VOH levels, and leakage currents-are fully characterized across -40 °C to +125 °C.

FAQ

Can the 74LVC1G240GM,115 operate with VCC = 1.65 V while accepting 5 V inputs?

Yes. The device features overvoltage-tolerant inputs rated to 5.5 V independent of VCC, allowing safe operation at minimum supply (1.65 V) while interfacing with 5 V upstream logic. This is enabled by internal clamping diodes and verified per JESD8-7 compliance.

What is the maximum capacitive load this device can drive while maintaining specified timing?

At VCC = 3.0 V and Tamb = +125 °C, the device maintains tpd ≤ 4.6 ns and tdis ≤ 7.0 ns up to 50 pF load capacitance, as confirmed in Table 8. For loads exceeding 50 pF, propagation delay increases linearly-designers should verify timing margins using the CPD = 25 pF value for dynamic power estimation.

Does the n.c. pin on the SOT886 package require any PCB layout treatment?

Pin 5 is internally unconnected and must not be soldered to ground or power. It may be left floating or tied to GND only if required by mechanical stability or thermal relief rules-but no electrical function is associated with it, and grounding does not affect IOFF or ESD performance.

How does the IOFF feature behave during power sequencing in a multi-rail system?

When VCC drops to 0 V, IOFF circuitry activates automatically, limiting output leakage to ±2 μA even if Y is pulled to 5.5 V externally. This prevents reverse current flow into the powered-down IC, protecting both the 74LVC1G240GM,115 and upstream drivers during asymmetric power-up/down sequences.
