NXP Semiconductors 74HC2G02GD,125

Overview

74HC2G02GD,125 from Nexperia is a dual 2-input NOR gate logic IC in XSON8 (SOT996-2) package, operating from 2.0 V to 6.0 V supply, delivering propagation delay of 8 ns at VCC = 6.0 V and 9 ns at VCC = 4.5 V, with CMOS-level input thresholds and high noise immunity for digital control signal conditioning in space-constrained industrial interfaces.

For engineers reviewing the 74HC2G02GD,125 datasheet, 74HC2G02GD,125 pinout, 74HC2G02GD,125 application, or 74HC2G02GD,125 equivalent, this device serves as a compact, low-power combinational logic building block for level-shifting, enable/disable gating, and bus arbitration where dual independent NOR functions are required within sub-2 mm² footprint.

Technical Context

The 74HC2G02GD,125 implements two independent 2-input NOR gates using standard CMOS technology, with inputs featuring integrated clamp diodes enabling safe interfacing to voltages exceeding VCC when used with current-limiting resistors. Its logic behavior strictly follows the truth table: output HIGH only when both inputs are LOW; otherwise output LOW.

It operates across -40 °C to +125 °C ambient temperature, supports dynamic power dissipation calculation via CPD = 10 pF, and exhibits static input leakage ≤ ±1.0 μA at VCC = 6.0 V - confirming robust off-state isolation and compatibility with battery-powered or thermally demanding embedded control nodes.

FAQ

What is the maximum allowable input voltage for 74HC2G02GD,125 when VCC = 5.0 V?

The absolute maximum input voltage is VCC + 0.5 V = 5.5 V, enabled by internal clamp diodes. Exceeding this value risks permanent damage unless current is limited to ±20 mA via external series resistors - a design practice confirmed in Section 6 of the official Nexperia datasheet Rev. 7.

Does 74HC2G02GD,125 support mixed-voltage operation between its inputs and VCC?

No - all inputs must remain within 0 V to VCC, though clamp diodes allow transient excursions up to VCC + 0.5 V with current limiting. The device does not support true level translation; for 3.3 V logic driving a 5 V VCC system, use 74HCT2G02GD instead, which features TTL-compatible input thresholds.

Can 74HC2G02GD,125 be used in automotive under-hood applications?

Yes - it is specified from -40 °C to +125 °C and qualified per JESD78 latch-up Class II Level B. However, Nexperia explicitly states it is "non-automotive qualified" in legal disclaimers; for ASIL-compliant systems, formal AEC-Q100 qualification testing must be performed by the end customer or authorized lab.

How does the exposed thermal pad on the XSON8 package affect PCB layout?

The exposed pad (pin 9, unmarked) must be soldered to a dedicated thermal land connected to a minimum 100 mm² internal copper pour or thermal via array. Failure to do so increases junction-to-ambient thermal resistance by >30 °C/W, risking thermal shutdown at >5 MHz toggle rates - per Nexperia's SOT996-2 package thermal characterization data.
