onsemi NLX2G02AMX1TCG

Overview

NLX2G02AMX1TCG from onsemi is a dual 2-input CMOS NOR gate in an ultra-small UDFN8 (1.45 × 1.0 mm) package, designed for high-speed logic interfacing in space-constrained applications. It operates from 1.65 V to 5.5 V, delivers 2.5 ns typical propagation delay at 5.0 V, supports 24 mA balanced output drive, and features overvoltage-tolerant (OVT) inputs up to 7.0 V - enabling robust level-shifting in mixed-voltage systems such as portable IoT sensor hubs.

For engineers reviewing the NLX2G02AMX1TCG datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage flexibility (1.65–5.5 V), OVT input tolerance, ultra-compact UDFN8 footprint, and guaranteed 24 mA output drive capability across industrial temperature range (−55 °C to +125 °C).

Technical Context

The NLX2G02AMX1TCG implements two independent CMOS NOR gates with fully buffered outputs and symmetrical rise/fall characteristics. Its input structure incorporates overvoltage protection diodes rated for continuous 7.0 V input regardless of V_CC, eliminating external clamping in level-shifted interfaces.

Propagation delays are balanced between t_PLH and t_PHL, and AC performance is specified under defined load conditions (R_L = 1 MΩ, C_L = 15 pF). Input leakage remains ≤1.0 µA across −55 °C to +125 °C, supporting low-power always-on subsystems.

FAQ

What is the maximum input voltage rating for NLX2G02AMX1TCG, and does it depend on V_CC?

The NLX2G02AMX1TCG supports a maximum DC input voltage of 7.0 V on all inputs (A1, B1, A2, B2), independent of the applied V_CC. This overvoltage tolerance is enabled by internal protection circuitry and is explicitly validated across the full operating temperature range (−55 °C to +125 °C), allowing direct connection to 5 V or 7 V signal sources even when V_CC is as low as 1.65 V.

Is NLX2G02AMX1TCG pin-compatible with other dual NOR gate variants in the NLX2G02 family?

Yes, NLX2G02AMX1TCG shares identical pinout and electrical behavior with other NLX2G02 variants (e.g., NLX2G02DMUTCG, NLX2G02EMUTCG), differing only in package dimensions (1.45 × 1.0 mm vs. 1.6 × 1.0 mm vs. 1.95 × 1.0 mm) and pitch (0.35 mm vs. 0.4 mm vs. 0.5 mm). All variants use the same UDFN8 pin assignment: Pin 1 = A1, Pin 2 = B1, Pin 3 = Y2, Pin 4 = GND, Pin 5 = A2, Pin 6 = B2, Pin 7 = Y1, Pin 8 = V_CC.

Can NLX2G02AMX1TCG drive standard TTL loads directly?

Yes, NLX2G02AMX1TCG can directly drive standard TTL loads due to its ±24 mA output drive capability and VOH/VOL specifications meeting TTL thresholds across its full V_CC range (1.65–5.5 V). At V_CC = 5.0 V, VOL ≤ 0.42 V at I_OL = 24 mA and VOH ≥ 4.0 V at I_OH = −24 mA - satisfying TTL input requirements without additional buffering.

Does NLX2G02AMX1TCG require external pull-up or pull-down resistors on unused inputs?

Yes, per the datasheet's Recommended Operating Conditions (Note 6), all unused inputs on NLX2G02AMX1TCG must be tied to a valid logic level - either V_CC or GND - using appropriate series resistance if needed for ESD or noise immunity. Leaving inputs floating may cause increased ICC, erratic output behavior, or latch-up risk, especially under temperature extremes.

What is the thermal resistance (θ_JA) specification for NLX2G02AMX1TCG in its UDFN8 (1.45 × 1.0 mm) package?

The NLX2G02AMX1TCG datasheet does not specify θ_JA for the UDFN8 1.45 × 1.0 mm (Case 517BZ) variant. Thermal resistance is marked "N/A" in the Maximum Ratings table. For thermal design, users should rely on the device's low power dissipation (ICC ≤ 10 µA at 25 °C) and ensure adequate copper pour and via stitching beneath the exposed pad (if present) - though this specific variant has no thermal pad per the 517BZ outline.
