onsemi NLV74HC86ADTR2G

Overview

NLV74HC86ADTR2G from onsemi is a quad 2-input exclusive-OR (XOR) gate in TSSOP-14 package, operating across 2.0–6.0 V supply, delivering propagation delay as low as 17 ns at 6.0 V, output drive capability of 10 LSTTL loads, and input leakage current ≤±1.0 µA - used in digital logic arbitration, parity generation, and signal-level XOR mixing in industrial control interfaces.

For engineers reviewing the NLV74HC86ADTR2G datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage range compatibility (2.0–6.0 V), guaranteed propagation delay across temperature (−55°C to +125°C), CMOS/TTL input compatibility with pullup resistors, and Pb-free TSSOP-14 packaging for high-density PCB layouts.

Technical Context

The NLV74HC86ADTR2G implements four independent XOR gates using high-performance silicon-gate CMOS technology, with each gate realizing Y = A ⊕ B = AB̅ + ĀB logic. It features rail-to-rail input voltage tolerance (0 to V_CC) and output swing within 0.1 V of rails under light load.

All inputs tolerate standard CMOS outputs natively and LSTTL outputs when externally pulled up; outputs directly interface to CMOS, NMOS, and TTL loads without level-shifting. The device meets JEDEC Std No. 7A and supports −55°C to +125°C operation with AEC-Q100 qualification for automotive-grade reliability.

FAQ

What logic family does NLV74HC86ADTR2G belong to, and how does it differ from standard 74HC86?

NLV74HC86ADTR2G is part of onsemi's NLV (Non-Legacy Vehicle) series - a variant of the 74HC logic family with enhanced automotive qualification (AEC-Q100 Grade 1), extended temperature range (−55°C to +125°C), and tighter process controls for zero-defect manufacturing. Unlike generic 74HC86, NLV74HC86ADTR2G undergoes additional stress screening and lot traceability per PPAP requirements, making it suitable for safety-critical automotive ECUs where standard HC parts are insufficient.

Can NLV74HC86ADTR2G interface directly with 3.3 V microcontrollers without level shifters?

Yes, NLV74HC86ADTR2G supports 2.0–6.0 V operation and has CMOS-compatible inputs that recognize 3.3 V logic high (VIH ≥ 2.1 V at VCC = 3.3 V) and low (VIL ≤ 0.9 V). Its outputs swing rail-to-rail, delivering ≥3.1 V high and ≤0.26 V low at 3.3 V supply - fully compatible with 3.3 V MCU GPIOs without external level translation.

What is the maximum clock frequency supported by NLV74HC86ADTR2G when used in toggle mode?

NLV74HC86ADTR2G is a combinational logic device with no internal clock; its usable toggle rate depends on propagation delay and system setup/hold timing. With t_PD = 17 ns (max at 6.0 V), the theoretical maximum toggle frequency is ~29 MHz in ideal conditions. In practice, with board trace capacitance and load, sustained reliable operation is verified up to 20 MHz in 50 pF-loaded configurations per onsemi AC characterization.

Does NLV74HC86ADTR2G require external pull-up resistors for TTL input compatibility?

Yes - when interfacing with LSTTL outputs (e.g., 74LSxx), NLV74HC86ADTR2G inputs require external pull-up resistors (typically 10 kΩ to V_CC) to ensure VIH exceeds 2.0 V minimum. Its native CMOS inputs do not source current, so passive pull-ups establish valid high-level recognition; no pull-ups are needed for standard CMOS or 74HCT-series drivers.

Is NLV74HC86ADTR2G pin-compatible with the obsolete 74LS86?

Yes, NLV74HC86ADTR2G is explicitly designed as a pinout-compatible replacement for 74LS86 (TTL quad XOR), sharing identical TSSOP-14 pin assignments and logic function. However, unlike LS86, it operates at lower power, supports wider voltage range, and provides higher noise immunity - enabling direct substitution in legacy designs with improved thermal and electrical margins.
