STMicroelectronics M74HC86RM13TR

Overview

M74HC86RM13TR from STMicroelectronics is a high-speed CMOS quad 2-input XOR gate in TSSOP-14 package, operating from 2V to 6V supply, with typical propagation delay of 12ns at 6V, symmetrical output drive (±4mA), and input noise immunity ≥28% VCC. It serves as a logic-level combinatorial function block in digital control, parity generation, and signal comparison circuits.

For engineers reviewing the M74HC86RM13TR datasheet, M74HC86RM13TR pinout, M74HC86RM13TR application, or M74HC86RM13TR equivalent, key selection factors include its rail-to-rail input voltage range (0–VCC), guaranteed 4mA output sink/source at 4.5V/6V, -55°C to +125°C operating temperature, and TSSOP-14 footprint compatibility with industry-standard PCB layouts.

Technical Context

The device implements four independent XOR logic functions using silicon gate C2MOS technology, with buffered inputs and outputs to ensure stable switching and high noise rejection. Each gate features identical AC timing behavior (tPLH ≅ tPHL) and matched output impedance for predictable signal integrity across all channels.

It supports wide-voltage operation (2–6V) without external level-shifting, and includes integrated ESD protection on all inputs. The design targets low-static-power systems, with ICC ≤ 1µA at 25°C and full functionality maintained over industrial and extended temperature ranges (-55°C to +125°C).

FAQ

Is M74HC86RM13TR pin-compatible with standard 74LS86?

Yes, it is functionally and pin-compatible with 74LS86 and other 74-series quad XOR gates. Its TSSOP-14 footprint matches the SOIC-14 pinout (14-pin dual-in-line spacing), and all input/output assignments align exactly-though voltage thresholds and drive strength differ due to CMOS vs. bipolar architecture.

What is the maximum capacitive load this device can drive reliably?

M74HC86RM13TR is characterized for CL = 50 pF in AC testing, and maintains specified tPLH/tPHL up to that load. For heavier loads (>100 pF), propagation delay increases nonlinearly; use series termination or buffer stages if driving transmission lines or multiple fan-outs exceeding 10 HC inputs.

Does this part support 3.3V-only systems?

Yes-it operates fully across 2V to 6V, including 3.3V nominal rails. At VCC = 3.3V, VOH ≥ 3.15V and VOL ≤ 0.33V under 4mA load, meeting 3.3V LVTTL and most 3.3V CMOS input thresholds without level shifting.

Can M74HC86RM13TR be used in analog phase-detection circuits?

Yes-its symmetrical XOR transfer characteristic enables linear phase-to-duty-cycle conversion near quadrature. When fed with two clean square waves, its output pulse width varies proportionally to phase difference, making it suitable for simple PLL phase detectors without external op-amps or multipliers.
