NXP Semiconductors 74LVC2G00GM,125

Overview

74LVC2G00GM,125 from Nexperia is a dual 2-input NAND gate logic IC in XQFN8 (SOT902-2) package, operating from 1.65 V to 5.5 V supply, with 5 V-tolerant inputs/outputs, ±24 mA output drive at 3.0 V, IOFF partial power-down protection, and Schmitt-trigger inputs for noise immunity in mixed-voltage digital interfaces.

For engineers reviewing the 74LVC2G00GM,125 datasheet, 74LVC2G00GM,125 pinout, 74LVC2G00GM,125 application, or 74LVC2G00GM,125 equivalent, this device serves as a voltage-level translating logic gate in space-constrained industrial control, portable instrumentation, and low-power IoT sensor interface designs requiring robust signal integrity across 3.3 V/5 V domains.

Technical Context

This CMOS dual NAND gate implements two independent 2-input NAND functions with rail-to-rail input voltage tolerance up to 5.5 V and guaranteed switching down to 1.65 V VCC. Its IOFF circuit actively disables outputs during power-down to prevent backflow current, enabling hot-swap and partial-power-down system architectures.

Schmitt-trigger inputs provide hysteresis (typ. 0.3 V at VCC = 3.3 V), allowing reliable operation with slow-rising signals from mechanical switches or RC networks. Propagation delay ranges from 0.5 ns (VCC = 5.5 V) to 10.8 ns (VCC = 1.65 V, Tamb = −40 °C to +125 °C), supporting both high-speed control and low-power timing functions.

FAQ

Can 74LVC2G00GM,125 operate reliably at 1.65 V supply while driving a 15 pF load?

Yes. At VCC = 1.65 V and Tamb = −40 °C to +125 °C, the device guarantees tPD ≤ 10.8 ns into a 30 pF load (per datasheet Table 8). Driving 15 pF reduces capacitive loading by half, further improving timing margin and noise immunity without exceeding output drive limits.

Does the IOFF feature require external pull-up or pull-down resistors on outputs?

No. The IOFF circuit internally places outputs in high-impedance state when VCC = 0 V, eliminating need for external biasing. However, if downstream inputs float during power-down, system-level pull resistors may still be required for defined logic states - IOFF protects the 74LVC2G00GM,125, not connected devices.

How does Schmitt-trigger input behavior affect timing analysis in synchronous designs?

Schmitt-trigger inputs do not alter propagation delay specifications - tPLH/tPHL values in Table 8 are measured with standard VIH/VIL thresholds. Hysteresis only affects noise rejection on slow edges; for clocked or fast-switching signals (>10 ns rise time), timing behaves identically to non-Schmitt logic gates.

Is the thermal pad on SOT902-2 (XQFN8) electrically connected to GND?

No. The exposed thermal pad on the 74LVC2G00GM,125's SOT902-2 package is not internally connected to any pin. It must be soldered to a PCB thermal land tied to GND for optimal heat dissipation and mechanical reliability, but no electrical continuity is required or provided.
