Product details
Overview
74AHCT1G86SE-7 from Diodes Incorporated is a single 2-input positive exclusive-OR (XOR) gate in SOT353 package, operating at 4.5V–5.5V supply, delivering ±8 mA output drive at 5.0V, with propagation delay of 6.9 ns (max, CL=15 pF) and Schmitt-trigger inputs for noise-immune signal conditioning. It serves as a logic-level combinatorial function block in digital interface synchronization and data path parity generation.
For engineers reviewing the 74AHCT1G86SE-7 datasheet, 74AHCT1G86SE-7 pinout, 74AHCT1G86SE-7 application, or 74AHCT1G86SE-7 equivalent, this page delivers verified functional identity, validated pin roles, confirmed timing and drive specs, real-world use cases, and technically grounded alternative options - all derived from Diodes Incorporated's official DS35185 Rev. 1-2 documentation.
Technical Context
This device implements the Boolean function Y = A ⊕ B using CMOS technology with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max), enabling direct interfacing with legacy 5V TTL logic families. Its Schmitt-trigger inputs provide hysteresis (typ. 0.4 V), improving immunity to slow-rising/falling signals and reducing susceptibility to noise-induced glitches.
The gate features totem-pole output structure, supporting rail-to-rail switching (VOH ≥ 3.70 V, VOL ≤ 0.55 V at IOL/IOH = ±8 mA), and operates across –40°C to +125°C ambient temperature with low ICC (max 40 μA) and Ci (max 10 pF), making it suitable for low-power, high-noise-margin embedded control paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | 2-input XOR: Y = A ⊕ B - enables parity checking, signal comparison, and controlled inversion |
| Supply Voltage Range | 4.5 V to 5.5 V - ensures compatibility with standard 5V TTL and mixed-voltage system rails |
| Output Drive Strength | ±8 mA at 5.0 V - sufficient to drive one 74-series TTL input or multiple CMOS loads without buffering |
| Propagation Delay | 6.9 ns max (CL = 15 pF, VCC = 4.5 V) - supports >100 MHz toggle rates in short-path logic networks |
| Input Hysteresis | Typ. 0.4 V (Schmitt-trigger action) - rejects noise on slow edges, eliminating need for external RC filtering |
| ESD Robustness | HBM >2000 V, CDM >1000 V, MM >200 V - meets industrial handling requirements without additional protection circuitry |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive, industrial PLC, and extended-range consumer applications |
Pinout & Package
SOT353 (5-pin small outline transistor) package: ultra-compact surface-mount footprint (2.0 × 2.2 mm body, 0.65 mm pitch), lead-free and RoHS-compliant, optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Data Input | First XOR operand; accepts TTL-compatible logic levels with Schmitt-trigger threshold |
| B | Data Input | Second XOR operand; electrically identical to Pin A, fully interchangeable |
| GND | Ground Reference | Return path for all internal currents; must be low-impedance to ensure noise margin and timing stability |
| Y | Data Output | Inverted XOR result; push-pull totem-pole output capable of sourcing/sinking ±8 mA |
| VCC | Power Supply | Positive supply rail (4.5–5.5 V); decoupling capacitor required within 5 mm for stable switching |
Key Features
| Feature | Design Value |
|---|---|

| TTL-compatible input thresholds | VIH ≥ 2.0 V and VIL ≤ 0.8 V allow direct connection to legacy 5V microcontrollers and peripheral ICs |
| Low dynamic power consumption | Cpd = 15 pF at 1 MHz - reduces switching current and heat in battery-powered or thermally constrained systems |
| Industrial temperature range | –40°C to +125°C operation - eliminates derating concerns in fanless enclosures or automotive junction boxes |
| Green molding compound | Halogen-free (no Br, Sb), compliant with IPC-4101D/21 and JEDEC J-STD-020 - supports eco-design and export compliance |
Applications
| PCB-Level Signal Integrity Enhancement | Microcontroller GPIO Expansion Logic |
|---|---|
Use Scenario: Mitigating ground bounce and crosstalk on densely routed 5V digital boards with marginal edge rates. IC Role / Device Role / Timing Role: XOR gate used as a controlled inverter to equalize net delays and reduce simultaneous switching noise. Use Value: Schmitt-trigger inputs tolerate <20 ns/V slew rates; ±8 mA drive sustains signal integrity over 5 cm FR-4 traces at 20 MHz. | Use Scenario: Extending limited GPIO count on an ARM Cortex-M0 MCU by encoding two inputs into one status line. IC Role / Device Role / Timing Role: Combinatorial logic element generating parity or difference flags for interrupt-driven sensor monitoring. Use Value: Propagation delay ≤6.9 ns ensures sub-100 ns response time; low ICC (<40 μA) preserves sleep-mode battery life. |
| Legacy System Interface Translation | Hardware-Based Data Path Parity Generation |
Use Scenario: Interfacing modern 5V FPGA I/O banks with older TTL peripherals lacking level-shifting capability. IC Role / Device Role / Timing Role: Level-tolerant logic buffer performing XOR-based protocol handshake signal conditioning. Use Value: VIH/VIL thresholds match TTL specs; totem-pole output drives 10 LS-TTL loads directly without pull-ups. | Use Scenario: Real-time error detection in serial data streams from ADCs or memory controllers where software parity is too slow. IC Role / Device Role / Timing Role: Single-bit parity generator feeding dedicated error-checking hardware blocks. Use Value: Guaranteed tpd ≤9.0 ns at –40°C to +125°C enables deterministic 100 Mbps parity insertion in safety-critical subsystems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G86DBVR | Wider VCC range (1.65–5.5 V), lower ICC (max 10 μA), but no Schmitt-trigger inputs | Preferred for multi-voltage systems (e.g., 3.3V MCU + 5V sensors); unsuitable for slow/noisy inputs | Select when voltage flexibility outweighs noise immunity needs |
| 74AHC1G86GW,125 | Same SOT353 package, higher speed (tpd ≤ 5.5 ns @ 5V), but only rated to +85°C ambient | Optimized for high-speed consumer electronics; not qualified for under-hood or industrial thermal environments | Select when maximum toggle rate is critical and temperature range is limited to commercial grade |
Compared with SN74LVC1G86DBVR and 74AHC1G86GW,125, the 74AHCT1G86SE-7 uniquely combines TTL-compatible thresholds, Schmitt-trigger noise rejection, and full industrial temperature support - making it the only choice for robust 5V logic interfacing in harsh or legacy-constrained designs.

FAQ
Can 74AHCT1G86SE-7 operate reliably at 4.5V minimum supply?
Yes. The device is fully specified down to 4.5 V: VOH ≥ 3.70 V and VOL ≤ 0.55 V at ±8 mA load, with guaranteed tpd ≤ 9.0 ns across –40°C to +125°C. Its TTL-compatible input thresholds remain valid, ensuring interoperability with legacy 5V logic even at nominal rail minimum.
Is the SOT353 package compatible with standard reflow profiles?
Yes. The SOT353 package is qualified for lead-free reflow per JEDEC J-STD-020, with peak temperature up to 260°C. Its thermal resistance (θJA = 371°C/W) requires adherence to Diodes' recommended pad layout (AP02001) - including thermal vias and copper pour - to maintain junction temperature within –40°C to +150°C limits.
Does the Schmitt-trigger input eliminate need for external RC filters?
Yes - for typical board-level noise sources. With 0.4 V typical hysteresis, the input rejects transients <400 mV and tolerates rise/fall times up to 20 ns/V. This replaces discrete RC debounce circuits in switch interfaces and long-line receivers, reducing BOM count and PCB area without sacrificing timing predictability.
What is the maximum capacitive load this gate can drive while maintaining spec?
The device is characterized up to 50 pF (tpd ≤ 10.5 ns at VCC = 4.5 V). For loads >15 pF, propagation delay increases linearly with capacitance; at 50 pF, delay remains within datasheet limits. Driving >50 pF risks violating timing margins and may require local buffering or reduced clock frequency in synchronous designs.
