Diodes Incorporated 74LVC1G10DW-7

Overview

74LVC1G10DW-7 from Diodes Incorporated is a single 3-input positive NAND gate in SOT363 package, operating from 1.65V to 5.5V supply, with ±24mA output drive at 3.3V, 5.5V-tolerant inputs, and IOFF partial-power-down protection. It performs the Boolean function Y = A·B·C and is used for voltage level shifting and signal isolation in mixed-voltage logic interfaces.

For engineers reviewing the 74LVC1G10DW-7 datasheet, 74LVC1G10DW-7 pinout, 74LVC1G10DW-7 application, or 74LVC1G10DW-7 equivalent, key selection criteria include input voltage tolerance, IOFF-enabled power-down behavior, propagation delay (≤3.8ns at 3.3V/15pF), output drive strength, and SOT363 thermal resistance (371°C/W).

Technical Context

This device implements a standard CMOS 3-input NAND gate with push-pull output stage and fully specified IOFF circuitry that disables outputs during power-down to prevent backflow current. Its input structure accepts voltages up to 5.5V regardless of VCC, enabling interoperability across 1.8V, 2.5V, 3.3V, and 5V domains.

Propagation delay is characterized across VCC (1.8V–5.5V) and temperature (–40°C to +125°C) with CL = 15pF and 30/50pF loads. Input capacitance is 3.5pF typical, and power dissipation capacitance is 19pF at 3.3V, supporting low-noise, low-power digital interfacing.

FAQ

Can 74LVC1G10DW-7 be used with 1.8V inputs while powered from 3.3V?

Yes. The device accepts input voltages from 0V to 5.5V regardless of VCC level. At VCC = 3.3V, a 1.8V input is recognized as logic HIGH because VIH(min) is 0.65×VCC = 2.145V - however, 1.8V falls below this threshold and will be interpreted as LOW. For reliable 1.8V HIGH detection, VCC must be ≤2.77V (since 0.65×2.77 ≈ 1.8V). Confirm logic thresholds using the Recommended Operating Conditions table.

What is the maximum capacitive load the output can drive while maintaining specified tpd?

The propagation delay is characterized up to CL = 50pF at VCC = 3.3V, with tpd ≤6.0ns (TA = –40°C to +125°C). Driving loads beyond 50pF increases delay nonlinearly and may cause marginal timing in high-speed paths. For loads >50pF, add series termination or buffer; the 24mA drive strength supports moderate RC time constants but does not guarantee signal integrity above 50pF without layout optimization.

Does the IOFF feature activate automatically when VCC drops below a threshold?

Yes. IOFF activates when VCC is below approximately 0.8V (per functional testing in Diodes datasheet DS35121), placing the output in high-impedance state regardless of input states. This occurs passively via internal circuitry - no external control signal is needed. Output leakage remains ≤±10μA, ensuring safe isolation during brown-out or staged power sequencing.

Is thermal derating required for continuous operation at 125°C ambient?

Yes. With θJA = 371°C/W in SOT363, power dissipation must be limited to ≤(125°C − 25°C)/371°C/W ≈ 270mW to maintain TJ ≤150°C. At 3.3V and 24mA output, worst-case dynamic power is ~79mW (P = V×I), well within limit. However, sustained static current or high-frequency switching increases junction temperature - use PCB copper pour under exposed pad and verify thermal performance in final layout.
