NXP Semiconductors 74HC2G00GD,125

Overview

74HC2G00GD,125 from Nexperia is a dual 2-input NAND gate in XSON8 (SOT996-2) package, operating from 2.0 V to 6.0 V supply, delivering symmetrical output impedance, balanced propagation delays (7–25 ns), and CMOS-level input compatibility. It serves as a fundamental logic building block in digital control circuits, level-shifting interfaces, and enable/disable signal conditioning for microcontroller peripherals.

For engineers reviewing the 74HC2G00GD,125 datasheet, 74HC2G00GD,125 pinout, 74HC2G00GD,125 application, or 74HC2G00GD,125 equivalent, this device is selected for low-power, rail-to-rail compatible combinational logic where input clamping diodes support safe interfacing to voltages exceeding VCC, and guaranteed operation across -40 °C to +125 °C industrial temperature range.

Technical Context

This device implements two independent NAND gates with identical input/output electrical behavior per channel. Each gate features integrated input clamp diodes enabling current-limited overvoltage tolerance, and exhibits matched tPLH/tPHL propagation delays under varying VCC (2.0 V–6.0 V) and load conditions.

Static performance includes VIH ≥ 3.15 V (at VCC = 4.5 V), VOL ≤ 0.33 V (IO = 4.0 mA), and ICC ≤ 20 μA per input at VCC = 6.0 V. Dynamic characteristics specify CPD = 10 pF and transition times as low as 5 ns (VCC = 6.0 V), supporting reliable operation up to ~20 MHz toggle rates in typical loads.

FAQ

Can 74HC2G00GD,125 operate reliably at 2.0 V supply?

Yes. The device is fully specified down to 2.0 V supply, with guaranteed VIH ≥ 1.5 V and VOL ≤ 0.5 V at IO = 20 μA (per datasheet Table 7). Propagation delay increases to 95 ns typical at 2.0 V, making it suitable for low-power, low-speed control logic where energy efficiency outweighs speed requirements.

Does the XSON8 package include a thermal pad?

No. The SOT996-2 (XSON8) package has a non-electrical thermal pad on the bottom center, but it is not internally connected to any die node and must not be soldered to a copper pour unless explicitly designated as "exposed pad – no connection" in the layout guidelines. Thermal dissipation relies on PCB copper area under the body and side-pad conduction.

What is the maximum capacitive load this device can drive?

At VCC = 4.5 V and Tamb = 25 °C, the device maintains specified VOL ≤ 0.33 V with IO = 4.0 mA. Using standard 50 pF test load (Table 10), it achieves tt ≤ 19 ns. For reliable operation, keep total load (including trace + probe + input capacitance) below 75 pF to avoid excessive transition time degradation or output voltage droop beyond spec limits.

How does input clamping affect external resistor selection?

Clamp diodes conduct when input voltage exceeds VCC + 0.5 V or falls below GND − 0.5 V. To limit IIK to ±20 mA (absolute max), use series resistors ≥ |(V_source − V_CC)| / 20 mA for overvoltage cases, e.g., 220 Ω for 12 V source into 3.3 V VCC. Resistor value must also preserve VIH/VIL thresholds under normal operation.
