Product details

Overview

74HCT86N,652 from NXP Semiconductors is a quad 2-input EXCLUSIVE-OR gate in a 14-lead DIP package, operating at 4.5 V to 5.5 V supply voltage with TTL-compatible input levels, 17 ns typical propagation delay at 4.5 V, and rated for −40 °C to +125 °C ambient temperature - used in digital logic arbitration, parity generation, and signal comparison circuits.

For engineers reviewing the 74HCT86N,652 datasheet, 74HCT86N,652 pinout, 74HCT86N,652 application, or 74HCT86N,652 equivalent, this page delivers verified electrical specs, validated DIP14 pin mapping, real-world use cases in industrial control and test equipment, and two confirmed alternative parts with documented functional and interface differences.

Technical Context

The 74HCT86N,652 implements four independent XOR gates using high-speed Si-gate CMOS technology compliant with JEDEC Std 7A and pin-compatible with LSTTL. Its TTL-level inputs (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 5.0 V) enable direct interfacing with legacy TTL outputs without level-shifting.

It features ESD protection exceeding 2000 V HBM and 200 V MM, operates across −40 °C to +125 °C, and delivers rail-to-rail CMOS output swing (VOH ≥ 3.7 V, VOL ≤ 0.4 V at IO = ±4 mA, VCC = 4.5 V), supporting robust noise immunity in mixed-signal environments.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Function	Quad 2-input EXCLUSIVE-OR (XOR); each gate outputs HIGH only when inputs differ.
Supply Voltage	4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL systems and stable operation under industrial rail tolerances.
Propagation Delay	17 ns typical (nA/nB to nY, VCC = 4.5 V, CL = 50 pF) - enables reliable timing in sub-60 MHz synchronous logic paths.
Input Compatibility	TTL-level inputs (VIH ≥ 2.0 V, VIL ≤ 0.8 V) - allows direct connection to 74LS/74F series without pull-ups or translators.
Operating Temperature	−40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLC I/O, and extended-range instrumentation.
Output Drive	±4.0 mA at VCC = 4.5 V (VOH ≥ 3.7 V, VOL ≤ 0.4 V) - sufficient to drive 10 LSTTL loads or multiple CMOS inputs.
ESD Protection	HBM > 2000 V, MM > 200 V - meets IEC 61000-4-2 pre-compliance for handling in non-ESD-controlled assembly areas.

Pinout & Package

DIP14 plastic dual in-line package (SOT27-1), 300 mil width, 2.54 mm lead pitch, through-hole mountable with 0.635 mm square leads and 5.08 mm row spacing.

Pin/Terminal	Circuit Role	Design Meaning
1, 4, 9, 12	1A–4A	First input per XOR gate; accepts TTL-level HIGH/LOW signals directly.
2, 5, 10, 13	1B–4B	Second input per XOR gate; electrically identical to A inputs, fully interchangeable.
3, 6, 8, 11	1Y–4Y	CMOS output per gate; rail-to-rail swing supports fan-out to downstream logic or analog comparators.
7	GND	Ground reference (0 V); must be low-impedance connection to minimize switching noise coupling.
14	VCC	Positive supply (4.5–5.5 V); requires local 100 nF ceramic decoupling within 10 mm of pin.

Key Features

Feature	Design Value
TTL-compatible inputs	Eliminates need for external level shifters when interfacing with 74LS, 74F, or microcontroller GPIOs configured as open-drain TTL drivers.
Rail-to-rail CMOS outputs	Ensures full logic swing (≥ 3.7 V HIGH, ≤ 0.4 V LOW at 4 mA load) for reliable noise margin against downstream Schmitt-trigger or ADC reference thresholds.
−40 °C to +125 °C operation	Validated performance across full industrial temperature range without derating - suitable for engine control units and power supply monitoring circuits.
JEDEC Std 7A compliance	Guarantees mechanical and electrical interoperability with legacy DIP-14 sockets and automated insertion equipment.
Low static current	ICC ≤ 40 µA at 125 °C - minimizes standby power in battery-backed diagnostic modules and always-on sensor interfaces.

Equivalent & Alternatives

The following parts are listed as comparable options for similar XOR gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC86APWR	3.3 V only supply (1.65–3.6 V); CMOS inputs; 3.5 ns typical tpd at 3.3 V.	Requires level translation for 5 V systems; superior speed and lower power in 3.3 V domains.	Select when migrating to modern low-voltage logic families and board-level voltage rails support 3.3 V operation.
74HC86N,652	CMOS inputs (VIH = 3.15 V min at VCC = 4.5 V); wider supply range (2.0–6.0 V); 14 ns tpd at 4.5 V.	Not TTL-compatible; unsuitable for direct connection to 74LS outputs without pull-ups.	Choose when system uses exclusively CMOS logic and requires broader supply flexibility or slightly faster propagation than 74HCT86N,652.

Compared with SN74LVC86APWR and 74HC86N,652, the 74HCT86N,652 uniquely bridges legacy 5 V TTL and modern CMOS systems without external components, offers guaranteed 125 °C operation, and maintains JEDEC 7A pinout compatibility - making it optimal for industrial retrofits and mixed-technology designs.

FAQ

What is the maximum supply voltage rating for the 74HCT86N,652?

The 74HCT86N,652 has an absolute maximum supply voltage (VCC) of +7.0 V, but its recommended operating range is strictly 4.5 V to 5.5 V. Operating above 5.5 V risks violating input/output voltage margins and may cause accelerated parametric drift or latent failure - always adhere to the 5.5 V upper limit specified in Table 5 of the NXP datasheet for reliable 74HCT86N,652 operation.

Does the 74HCT86N,652 support operation at −40 °C to +125 °C without derating?

Yes, the 74HCT86N,652 is fully characterized and guaranteed to meet all specifications - including propagation delay, output drive, and input thresholds - across the full −40 °C to +125 °C ambient temperature range. No thermal derating of supply voltage, frequency, or load is required, as confirmed in Table 5 (Recommended operating conditions) and Table 7 (Dynamic characteristics) of the NXP 74HCT86N,652 datasheet.

Can the 74HCT86N,652 directly interface with 74LS-series outputs?

Yes, the 74HCT86N,652 TTL-compatible inputs accept 74LS output voltages directly: VIH threshold is 2.0 V min and VIL is 0.8 V max at VCC = 5.0 V, matching LS-family VOH (2.7 V min) and VOL (0.5 V max). No pull-up resistors or level translators are needed - verified in Table 6 (Static characteristics) for the 74HCT86N,652 under −40 °C to +125 °C conditions.

What is the typical propagation delay of the 74HCT86N,652 at 5.0 V supply?

At VCC = 5.0 V with CL = 15 pF, the 74HCT86N,652 exhibits a typical propagation delay (tpd) of 14 ns (nA/nB to nY), as specified in Table 7 of the NXP datasheet. This value is measured under standard load conditions and represents the average delay across all four gates in the 74HCT86N,652 device.

Is the 74HCT86N,652 RoHS compliant and lead-free?

Yes, the 74HCT86N,652 is RoHS compliant and lead-free, consistent with NXP's product environmental compliance policy effective from 2006. The "N" suffix in the part number denotes a lead-free DIP package (SOT27-1), and full compliance documentation - including substance declarations and test reports - is available via NXP's official product page for 74HCT86N,652.
