SN74HCS86QPWRQ1 - Quad 2-Input XOR Gate, AEC-Q100 | TI
MPN: SN74HCS86QPWRQ1 ✓ פעילSN74HCS86QPWRQ1 סקירה
An XOR gate is a fundamental digital logic primitive in the combinational logic family of gates and inverters: its output is HIGH only when an odd number of inputs is HIGH, making it essential for adders, parity generation and checking, pseudo-random sequence generation, and signal comparison. The SN74HCS86-Q1 belongs to the HCS (HC with Schmitt) CMOS logic family, a modern low-power derivative of the classic 74HC high-speed CMOS series.
The key feature distinguishing this device is its Schmitt-trigger inputs, which tolerate slow or noisy input edges that would cause oscillation in standard CMOS gates. The wide 2 V to 6 V operating range supports legacy 5 V systems as well as 3.3 V and lower-voltage rails. The device offers very low static power consumption typical of CMOS logic, and automotive-grade robustness with HBM ESD Level 2 and CDM ESD classification Level C6 per the TI datasheet (Rev. C).
Because all four XOR gates are independent in a single package, the device consolidates parity trees, phase comparators, and code-comparison functions efficiently on board. Balanced drive capability and standardized TTL/CMOS-compatible thresholds at 5 V ease interfacing with microcontrollers and FPGAs.
Typical applications include automotive body and powertrain modules, gate drivers for isolated communication schemes, parity checkers in serial links, frequency doublers, and XOR-based CRC generation in industrial systems.
Design tip: keep unused inputs tied to VCC or GND (unused XOR gates may have inputs grounded) to prevent floating-node oscillation and excess current draw, and provide local 100 nF decoupling per TI logic application guidance.

יישומים טיפוסיים
SN74HCS86QPWRQ1 מתאים עבור 6 יישוםs: Automotive Body Electronics, Parity Generation and Checking, Gate Drive Interlock Logic, Frequency Doublers and Phase Comparison, Pseudo-Random Sequence and CRC Generation, Signal Comparison and Address Decoding.
Automotive Body Electronics
The SN74HCS86QPWRQ1 is AEC-Q100 grade-1 qualified for -40C to +125C, making it well suited to body-control modules, lighting logic, and door-zone ECUs. Its Schmitt-trigger inputs reject noise on switch matrix and harness-routed signals, where long wiring picks up transients. Used for command XOR-ing and safety interlock checks, its 2 V to 6 V range tolerates battery-system supply sag, reducing risk of logic errors during crank conditions.
מומלץ
Parity Generation and Checking
XOR gates are the canonical element for parity trees: cascading four XOR gates checks or generates even parity over serial and parallel buses. The SN74HCS86QPWRQ1 provides four independent gates per package, allowing a 4-to-16-input parity tree with a few ICs. Schmitt-trigger inputs keep the tree stable when data lines arrive with slow or ringing edges, a common condition in industrial cable runs, improving error-detection reliability over plain HC86 alternatives.
מומלץ
Gate Drive Interlock Logic
In motor drives and power converters, XOR gates combine PWM and enable signals to implement shoot-through interlocks and dead-time validation. The SN74HCS86QPWRQ1 grades-1 temperature rating suits underhood environments, and Schmitt inputs prevent oscillation from the ringing edges common on gate-drive PCBs. At 2 V to 6 V it interfaces directly with 3.3 V or 5 V MCU ports, feeding isolated gate-driver inputs with deterministic, glitch-free logic states.
מומלץ
Frequency Doublers and Phase Comparison
XOR of a clock with its delayed copy produces a frequency-doubled output; the propagation path is typically an RC or gate delay. The SN74HCS86QPWRQ1 fits this role because Schmitt inputs provide a clean, deterministic threshold, minimizing jitter contribution from slow clock edges. Its low-power CMOS process limits added supply noise, and its -40C to +125C range keeps delay variations within automotive expectations across temperature excursions.
מומלץ
Pseudo-Random Sequence and CRC Generation
Linear feedback shift registers use XOR taps to generate pseudo-random sequences and CRC checksums in automotive and industrial communication links. The SN74HCS86QPWRQ1 supplies the tap XORs; four gates per package let a compact LFSR fit in one or two devices. Wide 2 V to 6 V operation matches 3.3 V and 5 V logic families, and Schmitt inputs stabilize feedback signals on longer PCB traces, supporting reliable code generation at system level.
מומלץ
Signal Comparison and Address Decoding
XOR-based comparators detect inequality between two bit vectors: any XOR output HIGH indicates a mismatch, useful in address decoding, jumper-based configuration, and tamper detection. The SN74HCS86QPWRQ1 grade-1 automotive qualification suits ECUs that validate configuration straps. Schmitt-trigger inputs tolerate slow strap voltage settling during power-up from RC networks, ensuring glitch-free comparison results where standard CMOS inputs could oscillate through the threshold region.

הערות תכנון
Tie all unused inputs to VCC or GND; for unused XOR gates, ground both inputs to hold the output LOW. Floating CMOS Schmitt inputs can still pick up noise and inject switching current into the supply. Never leave any input pin open, even momentarily during bench testing, and avoid routing inputs across switching power traces.
Place a 100 nF ceramic decoupling capacitor within 5 mm of the VCC pin, plus bulk capacitance per board guidance. Keep XOR outputs away from Schmitt inputs to prevent ground-bounce coupling; use a solid ground plane. The TSSOP-14 (PW) thermal pad requirements are minimal since CMOS logic dissipates little static power, but switching at high frequency with heavy loads increases dynamic dissipation.
The Schmitt-trigger inputs tolerate slow edges, but do not intentionally rely on hysteresis for signals with sub-nanosecond ringing near thresholds. For 5 V systems interfacing TTL sources, verify VIH/VOH margins in the datasheet at the applicable VCC; at 3.3 V operation, switching speed derates - confirm timing budget at the design corner temperatures of -40C and +125C.
