Nexperia USA Inc. 74LVCU04ADB,112

Overview

74LVCU04ADB,112 from Nexperia is a hex unbuffered inverter IC operating from 1.2 V to 3.6 V supply, with 5.5 V-tolerant inputs enabling level translation between 3.3 V and 5 V logic domains. It delivers six independent CMOS inverters in a 14-lead SSOP package (SOT337-1), specified for -40 °C to +125 °C operation and used in crystal oscillator circuits, linear amplifiers, and astable multivibrators.

For engineers reviewing the 74LVCU04ADB,112 datasheet, 74LVCU04ADB,112 pinout, 74LVCU04ADB,112 application, or 74LVCU04ADB,112 equivalent, key selection criteria include input voltage tolerance (up to 5.5 V), propagation delay (as low as 2.0 ns at 3.3 V), output drive capability (±24 mA), thermal performance in SSOP packaging, and JEDEC-compliant interface standards (JESD8-7A/5A/C).

Technical Context

The 74LVCU04ADB,112 implements six independent unbuffered CMOS inverter stages without internal buffering, resulting in symmetrical rise/fall times and low propagation skew (<1.5 ns). Its input structure accepts voltages up to 5.5 V regardless of VCC, enabling direct interfacing with legacy 5 V TTL outputs while powered from 1.65–3.6 V supplies.

It supports mixed-voltage system design via rail-to-rail input compatibility and complies with JEDEC standards JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V). The device exhibits low dynamic power dissipation (CPD = 8.4 pF at 3.3 V) and operates across industrial and extended temperature ranges (-40 °C to +125 °C).

FAQ

Can 74LVCU04ADB,112 operate with a 1.2 V supply?

Yes. The device is fully specified down to 1.2 V supply voltage per its recommended operating conditions. At this voltage, propagation delay increases to 6.0 ns (typical), VIH rises to 1.08 V, and VOL remains ≤0.12 V at -100 μA load-enabling ultra-low-power operation in battery-powered sensor nodes and wearables.

Is the SSOP package (SOT337-1) thermally adequate for continuous 125 °C operation?

Yes. The SOT337-1 package has a junction-to-ambient thermal resistance (RθJA) of 120 K/W (typical), and with a maximum total power dissipation of 500 mW, the junction temperature remains within safe limits at 125 °C ambient when power dissipation stays below 200 mW-achievable in most oscillator and logic translation use cases.

Does 74LVCU04ADB,112 require external pull-up resistors on inputs?

No. The inputs have no internal pull-up or pull-down resistors and exhibit ≤±0.1 μA leakage current. External biasing is required only when driving from high-impedance sources or implementing linear amplifier configurations; for digital use, inputs must be actively driven to defined logic levels to prevent floating states and excessive ICC.

How does the unbuffered architecture affect oscillator phase noise?

The unbuffered design minimizes internal propagation asymmetry and reduces jitter accumulation across the inverter chain. Measured phase noise in Pierce oscillator configurations is typically -110 dBc/Hz at 10 kHz offset (at 10 MHz), outperforming buffered equivalents by 8–10 dB due to absence of internal stage delays and reduced internal node capacitance.
