STMicroelectronics 74LVQ04TTR

Overview

74LVQ04TTR from STMicroelectronics is a low-voltage CMOS hex inverter with 6 independent inverting buffers, operating from 2.0 V to 3.6 V supply, delivering 4.5 ns typical propagation delay at 3.3 V, 12 mA symmetrical output drive, and 2 kV ESD immunity-used in 3.3 V logic interfacing, PCI bus signal conditioning, and noise-sensitive digital subsystems.

For engineers reviewing the 74LVQ04TTR datasheet, 74LVQ04TTR pinout, 74LVQ04TTR application, or 74LVQ04TTR equivalent, key selection criteria include transmission-line driving capability (75 Ω), balanced tPLH/tPHL skew (<1.0 ns), low dynamic noise (VOLP = 0.3 V typ.), and guaranteed PCI-level drive (24 mA) under industrial temperature range (–55 °C to +125 °C).

Technical Context

The device implements three-stage buffered CMOS inverter architecture with internal clamping diodes and double-layer metal wiring C2MOS process, enabling high noise immunity and stable rail-to-rail switching across its 2–3.6 V operating range. Input thresholds are specified at VIH = 2.0 V min and VIL = 0.8 V max over full temperature range.

Output stages provide symmetrical sourcing/sinking (|IOH| = IOL ≥ 12 mA at VCC = 3.0 V), support incident-wave switching on 75 Ω transmission lines, and maintain <1.0 ns output-to-output skew under AC load conditions (CL = 50 pF, RL = 500 Ω).

FAQ

Is 74LVQ04TTR pin-compatible with standard 74-series hex inverters?

Yes, it is pin- and function-compatible with 74LS04 and 74HC04 in TSSOP-14 packages. All six inverter inputs (pins 1,3,5,9,11,13) and outputs (2,4,6,8,10,12) map identically, with GND on pin 7 and VCC on pin 14. No PCB redesign is needed for drop-in replacement in 3.3 V systems.

Does 74LVQ04TTR support 5 V-tolerant inputs?

No. Its absolute maximum input voltage is VCC + 0.5 V, and recommended operating VI is 0–VCC. With VCC = 3.3 V, inputs must stay within 0–3.3 V. It is not 5 V tolerant; interfacing with 5 V logic requires level-shifting circuitry or a different device family.

What is the significance of the "Q" in 74LVQ04?

The "Q" denotes STMicroelectronics' proprietary enhanced performance grade: improved latch-up immunity, tighter AC timing specs (e.g., skew ≤1.0 ns), and guaranteed 75 Ω transmission-line driving capability-differentiating it from baseline 74LV04 devices which lack these industrial-grade assurances.

Can 74LVQ04TTR operate reliably at 2.0 V supply?

Yes. It is fully specified down to 2.0 V VCC across –55 °C to +125 °C, with VIH = 2.0 V min and VIL = 0.8 V max guaranteed. At 2.0 V, tPD increases to 11.0 ns (max), and output drive reduces to ≥6 mA, but all logic functions and DC specs remain valid per Table 5.
