Nexperia USA Inc. 74HC2G02DP,125

Overview

74HC2G02DP,125 from Nexperia is a dual 2-input NOR gate logic IC in TSSOP8 (SOT505-2) package, operating from 2.0 V to 6.0 V supply, delivering propagation delay as low as 8 ns at VCC = 6.0 V and CL = 15 pF, with CMOS-level input compatibility and -40 °C to +125 °C temperature range - used in digital control signal conditioning and bus arbitration circuits.

For engineers reviewing the 74HC2G02DP,125 datasheet, 74HC2G02DP,125 pinout, 74HC2G02DP,125 application, or 74HC2G02DP,125 equivalent, this device supports high-noise-immunity combinational logic in space-constrained industrial controllers, sensor interface modules, and power management sequencers where dual independent NOR functions are required.

Technical Context

The 74HC2G02DP 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. Each gate exhibits symmetrical propagation delays (tPLH ≈ tPHL) and transition times (tTLH ≈ tTHL), verified across full voltage and temperature ranges.

It operates within JEDEC-compliant supply conditions (2.0–6.0 V for HC variant), supports TTL-compatible input thresholds only in the HCT version (not applicable here), and maintains static input leakage ≤ ±1.0 μA and output drive capability of ±4.0 mA at VCC = 4.5 V - confirming robustness in mixed-voltage system interconnects.

FAQ

Is the 74HC2G02DP,125 compatible with 3.3 V microcontroller GPIOs?

Yes - its 2.0 V to 6.0 V supply range and CMOS input thresholds allow direct connection to 3.3 V logic. At VCC = 3.3 V, VIH is typically 2.3 V and VIL is 1.1 V, providing >0.8 V noise margin against standard 3.3 V CMOS levels. Output VOH/VOL remain rail-to-rail compliant, ensuring reliable drive into 3.3 V inputs without level shifters.

Does the 74HC2G02DP,125 require external pull-up or pull-down resistors on unused inputs?

No - unused inputs must be tied to VCC or GND to prevent floating states, but external resistors are unnecessary. The internal input structure has no weak pull-ups; leaving an input unconnected risks oscillation and increased ICC. Direct connection to VCC or GND ensures defined logic state and minimal power consumption, consistent with standard HC-series practice.

Can the 74HC2G02DP,125 drive a 50 pF load at 10 MHz without signal degradation?

Yes - with CPD = 10 pF and typical tpd = 9 ns at VCC = 4.5 V, CL = 15 pF, the device maintains clean edges into 50 pF loads. Measured tt (transition time) is ≤19 ns at VCC = 4.5 V, ensuring <10 % overshoot and monotonic edges even at 10 MHz toggle rates, provided proper PCB layout (short traces, ground plane, local decoupling) is followed.

What is the maximum junction temperature for continuous operation in the TSSOP8 package?

The absolute maximum junction temperature is +150 °C, but continuous operation is limited by thermal resistance. For SOT505-2, RθJA = 125 K/W (typical). At 250 mW max power and Tamb = +125 °C, TJ ≈ 156 °C - exceeding rating. Derating begins at +96 °C ambient (4.6 mW/K), so sustained 250 mW operation requires Tamb ≤ +80 °C or forced cooling to maintain TJ ≤ +150 °C.
