STMicroelectronics 74LVX86MTR

Overview

74LVX86MTR from STMicroelectronics is a low-voltage CMOS quad exclusive-OR gate with 5V-tolerant inputs, operating from 2V to 3.6V supply, delivering 5.8 ns typical propagation delay at 3.3V, ±4 mA symmetrical output drive, and 2 µA max quiescent current - used in level-shifting logic interfaces between 5V and 3.3V systems.

For engineers reviewing the 74LVX86MTR datasheet, 74LVX86MTR pinout, 74LVX86MTR application, or 74LVX86MTR equivalent, key selection criteria include 5V input tolerance, sub-10 ns AC performance at 3.3V, ESD-hardened I/O (2 kV), power-down input protection, and SO-14 pin compatibility with standard 74-series 86 logic.

Technical Context

This device implements four independent XOR gates using sub-micron C2MOS technology, enabling true CMOS low-power operation while maintaining high-speed switching. Its input structure accepts 0–7 V regardless of VCC, supporting hot-swap and mixed-voltage bus interfacing without external clamping.

The symmetrical output impedance (|IOH| = IOL ≥ 4 mA) and balanced tPLH/tPHL delays ensure minimal duty-cycle distortion in clock or data path applications. All inputs feature diode-based protection and latch-up immunity per JEDEC JESD78.

Key Specifications

Pinout & Package

74LVX86MTR is housed in a 14-pin SOIC (Small Outline Integrated Circuit) package, 3.9 mm body width, 1.27 mm lead pitch, tape-and-reel format (MTR suffix). Pin 7 is GND; Pin 14 is V_CC; all inputs tolerate 0–7 V independent of supply.

FAQ

Can 74LVX86MTR operate with V_CC = 2.0 V and still meet t_PD < 15 ns?

Yes. At V_CC = 2.0 V and CL = 15 pF, t_PLH/t_PHL is guaranteed ≤14.5 ns over −40°C to +85°C. The device remains fully functional across its entire 2.0–3.6 V operating range, with timing degradation bounded per AC Electrical Characteristics Table 8.

Does 74LVX86MTR require external pull-up or pull-down resistors on unused inputs?

No. Unused inputs may be left floating only if V_CC is powered and stable; however, STMicroelectronics recommends tying them to V_CC or GND to prevent noise-induced switching and minimize ICC. Floating inputs increase susceptibility to EMI and may cause unintended output transitions.

What is the maximum capacitive load CL that 74LVX86MTR can drive while maintaining t_PD ≤ 12.8 ns?

At V_CC = 3.3 V, the device guarantees t_PD ≤ 12.8 ns for CL = 50 pF (Table 8). Driving loads >50 pF increases propagation delay nonlinearly and may degrade edge rate; for >50 pF, verify timing margins with actual board parasitics and consider buffering.

Is 74LVX86MTR compatible with lead-free reflow profiles?

Yes. The SO-14 package (MTR) is RoHS-compliant and qualified for standard lead-free reflow per JEDEC J-STD-020. Peak temperature (260°C) and time above liquidus (60–150 s) are within specification; see STMicroelectronics package mechanical data document 0016019D for thermal profile guidance.
