STMicroelectronics 74LVQ86MTR

Overview

74LVQ86MTR from STMicroelectronics is a low-voltage CMOS quad exclusive-OR gate operating from 2.0 V to 3.6 V, delivering symmetrical output drive (±12 mA), 5.5 ns typical propagation delay at 3.3 V, and 75 Ω transmission line driving capability-used in noise-sensitive 3.3 V logic interfacing, bus arbitration, and parity generation circuits.

For engineers reviewing the 74LVQ86MTR datasheet, 74LVQ86MTR pinout, 74LVQ86MTR application, or 74LVQ86MTR equivalent, key selection criteria include guaranteed PCI bus levels at 24 mA, balanced tPLH/tPHL delays, 2 µA max quiescent current, ESD immunity up to 2 kV, and SO-14 tape-and-reel packaging for automated assembly.

Technical Context

The device implements four independent XOR logic functions using sub-micron C2MOS technology with double-layer metal interconnect, enabling low-noise switching and latch-up immunity. Input thresholds are fixed at VIH = 2.0 V and VIL = 0.8 V over full VCC range (2–3.6 V), ensuring TTL-compatible interfacing.

Dynamic performance is characterized under CL = 50 pF and RL = 500 Ω, with output skew ≤1.0 ns across all gates and VOLP = 0.3 V typical at 3.3 V-critical for minimizing ground bounce in high-speed digital systems.

FAQ

Is 74LVQ86MTR compatible with 5 V TTL inputs?

Yes-its VIH threshold is guaranteed at 2.0 V minimum over 2–3.6 V VCC, and inputs tolerate up to VCC + 0.5 V. When driven by 5 V TTL outputs, an external pull-up to VCC or series resistor may be needed to limit input current, but direct interface is functional with proper VCC biasing.

What is the maximum output current per pin under continuous DC conditions?

The absolute maximum DC output current per pin is ±50 mA, per Absolute Maximum Ratings Table 4. However, for guaranteed operation across temperature, the datasheet specifies ±12 mA minimum at VCC = 3.0 V and ±24 mA for PCI-compliant transient drive-continuous use above ±12 mA requires thermal derating verification.

Does 74LVQ86MTR support hot insertion?

No-hot insertion is not characterized or guaranteed. The device lacks bus-hold or powered-off protection circuitry. Inputs are protected against ESD (2 kV HBM), but applying signals while VCC is unpowered risks latch-up or damage due to forward-biased input diodes.

Can 74LVQ86MTR operate at 1.8 V?

No-it is not specified or guaranteed below 2.0 V. The recommended operating range starts at 2.0 V, and truth table functionality is only assured from 1.2 V (data retention) up to 3.6 V. At 1.8 V, propagation delay increases significantly and output drive degrades beyond specification limits.
