Nexperia USA Inc. 74LV04DB,118

Overview

74LV04DB,118 from Nexperia is a hex CMOS inverter logic IC with six independent inverting buffers, operating across 1.0 V to 5.5 V supply, delivering 6 ns typical propagation delay at 3.3 V/15 pF, ±12 mA output drive, and input clamp diodes enabling safe interfacing to voltages exceeding VCC - used in voltage-level translation and signal inversion within industrial control I/O modules.

For engineers reviewing the 74LV04DB,118 datasheet, 74LV04DB,118 pinout, 74LV04DB,118 application, or 74LV04DB,118 equivalent, this device is selected for low-voltage logic inversion where rail-to-rail input tolerance, sub-10 ns timing at 3.3 V, and -40 °C to +125 °C operation are required in space-constrained PCB layouts using SSOP14 packaging.

Technical Context

The 74LV04DB,118 implements six identical unbuffered CMOS inverter stages with symmetrical input thresholds and rail-referenced switching points. Each gate features integrated input clamp diodes to GND and VCC, allowing current-limited overvoltage input handling up to ±20 mA per pin without damage.

It operates as a pure combinatorial logic element with no internal latching or feedback; propagation delay varies predictably with supply voltage (e.g., 14 ns at 2.0 V, 6 ns at 3.3 V) and load capacitance, and output drive strength is specified at ±6 mA (VOL ≤ 0.4 V, VOH ≥ 2.82 V) under 3.0 V conditions.

FAQ

Is 74LV04DB,118 pin-compatible with standard 74HC04 or 74LS04 packages?

No. The 74LV04DB,118 uses SOT337-1 (SSOP14), which has 0.65 mm lead pitch and 5.3 mm body width - incompatible with SO14 (1.27 mm pitch) or DIP14 footprints. Mechanical adaptation requires PCB redesign; electrical behavior differs significantly due to LV-specific input thresholds and clamp diodes.

Can 74LV04DB,118 drive a 50 pF capacitive load at 10 MHz without waveform degradation?

Yes. At VCC = 3.3 V, tpd remains ≤12 ns (max) with CL = 50 pF, and CPD = 21 pF ensures dynamic power dissipation stays below 0.5 mW per gate at 10 MHz - verified by Nexperia's Fig. 4 and Table 7 data under -40 °C to +125 °C conditions.

What is the maximum allowable input voltage when VCC = 1.8 V?

Per Table 4, VI may exceed VCC by up to 0.5 V if IIK ≤ ±20 mA. With external 1 kΩ series resistor, a 5 V input yields ~3.2 mA into the clamp diode - well within safe limits. Absolute max VI is VCC + 0.5 V = 2.3 V without current limiting.

Does 74LV04DB,118 support partial power-down (Ioff) functionality?

No. The device lacks Ioff protection; when VCC = 0 V, inputs and outputs remain high-impedance but are not actively isolated. Unpowered operation risks back-driving through clamp diodes - external isolation switches or bus-hold circuits are required for hot-swap scenarios.
