STMicroelectronics 74LVQ08MTR

Overview

74LVQ08MTR from STMicroelectronics is a low-voltage CMOS quad 2-input AND gate optimized for 3.3 V digital logic systems, featuring 5.6 ns typical propagation delay at V_CC = 3.3 V, ±12 mA symmetrical output drive, and 2 V to 3.6 V operating voltage range. It delivers low-noise operation (V_OLP = 0.3 V typ.), 75 Ω transmission line driving capability, and 2 kV ESD immunity-ideal for PCI bus interfacing and noise-sensitive embedded control logic.

For engineers reviewing the 74LVQ08MTR datasheet, 74LVQ08MTR pinout, 74LVQ08MTR application, or 74LVQ08MTR equivalent, key selection criteria include propagation delay matching, 3.3 V rail compatibility, symmetrical I_OH/I_OL drive strength, transmission-line termination support, and SOP-14 package fit in space-constrained PCB layouts.

Technical Context

The 74LVQ08MTR implements four independent AND gates using sub-micron C2MOS technology with buffered outputs, enabling high noise immunity and stable switching across industrial temperature ranges (–55 °C to +125 °C). Its input structure guarantees TTL-compatible thresholds and supports 1.2 V data retention during brown-out conditions.

Dynamic performance is characterized under controlled 50 pF load and 3 ns input edge rates, with balanced t_PLH ≅ t_PHL propagation delays and <1.0 ns output-to-output skew at 3.3 V. Input rise/fall time tolerance is specified up to 10 ns/V, supporting robust timing margin in mixed-signal environments.

FAQ

Is 74LVQ08MTR compatible with 5 V TTL inputs?

Yes-its input thresholds (V_IL ≤ 0.8 V, V_IH ≥ 2.0 V) are TTL-compatible, allowing direct connection to 5 V logic outputs. However, V_CC must remain within 2.0–3.6 V; applying 5 V to V_CC will damage the device. External clamping or level-shifting is required only if 5 V appears on inputs exceeding V_CC + 0.5 V.

What is the maximum recommended output load capacitance?

The AC specifications-including 5.6 ns typical propagation delay-are characterized at C_L = 50 pF. Operation beyond 75 pF increases t_PD nonlinearly and may cause excessive overshoot; for loads >50 pF, derate timing margins by ≥30% and verify stability with actual board parasitics using IBIS simulation.

Does 74LVQ08MTR support hot insertion?

No-74LVQ08MTR lacks explicit hot-swap circuitry such as power-up sequencing control or I_ON current limiting. While its absolute maximum ratings allow brief V_CC ramp-up, uncontrolled hot insertion risks latch-up due to supply-rail transients; use dedicated hot-swap controllers or sequenced power supplies in live-backplane applications.

Can unused gates be left floating?

No-unused inputs must be tied to V_CC or GND via ≤10 kΩ resistors. Floating CMOS inputs cause increased ICC, unpredictable logic states, and potential oscillation due to noise coupling, which degrades noise immunity and may violate the 2 µA quiescent current specification.
