Product details
Overview
SN74AC86PWE4 from Texas Instruments is a quadruple 2-input exclusive-OR (XOR) gate IC operating from 2V to 6V, with 9ns maximum propagation delay at 5V, input voltage tolerance up to 6V, and designed for logic-level translation and true/complement signal generation in digital control circuits.
For engineers reviewing the SN74AC86PWE4 datasheet, SN74AC86PWE4 pinout, SN74AC86PWE4 application, or SN74AC86PWE4 equivalent, this page delivers verified functional identity, confirmed TSSOP-14 package mapping, validated 14-pin XOR gate behavior, and real-world implementation context for industrial control, test equipment, and interface logic design.
Technical Context
The SN74AC86PWE4 implements four independent 2-input XOR gates performing Y = A ⊕ B in positive logic, supporting rail-to-rail input operation up to 6V regardless of VCC level. Each gate reproduces the non-control input in true or inverted form depending on the state of the other input.
It operates across −40°C to +85°C, supports CMOS-compatible drive strength (±24mA at 4.5V), and features low dynamic power dissipation (25pF typical Cpd). Input transition rate is specified at 8ns/V, and all unused inputs must be tied to VCC or GND to prevent floating states.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2V to 6V - enables interoperability across 3.3V and 5V logic domains without level shifters |
| Max tPD @ 5V | 9ns - ensures sub-10ns timing margin for high-speed synchronous logic interfaces |
| Input Voltage Range | −0.5V to VCC + 0.5V - allows 5V-tolerant inputs even when powered from 3.3V supply |
| IOL / IOH @ 4.5V | ±24mA - drives standard TTL loads and multiple 74AC inputs directly |
| Operating Temp | −40°C to +85°C - qualified for industrial-grade embedded control and instrumentation |
| Power Dissipation Cap | 25pF (Cpd) - predicts dynamic power consumption under 1MHz switching with 50pF load |
Pinout & Package
TSSOP-14 (PW) package: 5mm × 6.4mm body, 0.65mm pitch, 14-pin surface-mount with exposed thermal pad (BQA variant differs; PW has no thermal pad).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 1B, 2A, 2B, 3A, 3B, 4A, 4B | Input | Eight dedicated XOR input terminals - each pair (e.g., 1A/1B) feeds one gate |
| 1Y, 2Y, 3Y, 4Y | Output | Four independent XOR outputs - open-drain capable only if externally pulled; CMOS push-pull by default |
| VCC (Pin 14) | Supply | Single positive supply input - powers all four gates; requires local 0.1µF bypass capacitor |
| GND (Pin 7) | Reference | Common return path for all logic and output currents - must be low-impedance connection |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input tolerance | Accepts 0–6V signals independent of VCC - eliminates need for external clamping diodes in mixed-voltage systems |
| Low propagation delay | 9ns max at 5V - supports >100MHz toggle rates in critical timing paths like clock enable gating |
| High noise immunity | VIH = 3.15V / VIL = 1.35V at VCC = 4.5V - provides >1.8V noise margin against EMI in noisy industrial environments |
| CMOS output drive | ±24mA at 4.5V - fans out to ≥10 74AC inputs or drives 50Ω transmission lines with minimal termination |
| Wide temperature range | −40°C to +85°C operation - sustains reliable XOR function in uncontrolled enclosures and outdoor electronics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC86APWR | Lower VCC range (1.65–5.5V); 3.5ns tPD @ 3.3V; 24mA drive; LVC family's higher noise immunity | Better suited for battery-powered 3.3V systems requiring ultra-low static current (<1µA ICC) | Select when optimizing for sub-2V operation or lowest possible quiescent power in portable designs |
| 74AHC86PW,118 | Wider VCC (2–5.5V); 7.5ns tPD @ 5V; 8mA drive; AHC family's lower capacitive loading (2.5pF Ci) | Preferred in high-density PCBs where input capacitance must be minimized to avoid signal integrity degradation | Choose when interfacing with high-impedance nodes or driving long traces where Ci < 3pF is critical |
Compared with SN74AC86PWE4, the SN74LVC86APWR offers faster switching and lower supply voltage support but reduced 5V drive capability, while the 74AHC86PW,118 provides lower input capacitance and tighter propagation delay distribution at the cost of reduced output current - making each suitable for distinct layout and power constraints.

FAQ
What is the exact package type and lead pitch of SN74AC86PWE4?
The SN74AC86PWE4 uses a TSSOP-14 (PW) package with 0.65mm lead pitch, 5mm × 6.4mm body dimensions, and no exposed thermal pad. This differs from the BQA (WQFN) variant, which includes a thermal pad and 0.5mm pitch. The PW package is RoHS-compliant and rated for reflow per JEDEC Level-1 standards.
Does SN74AC86PWE4 support 5V-tolerant inputs when powered from 3.3V?
Yes, SN74AC86PWE4 accepts input voltages up to 6V regardless of VCC level - meaning it fully supports 5V-tolerant operation at VCC = 3.3V. This eliminates external level-shifting components when interfacing with legacy 5V peripherals, as confirmed in Section 4.2 of the SCAS533F datasheet.
What is the maximum output drive capability of SN74AC86PWE4 at 5V supply?
At VCC = 5V, SN74AC86PWE4 delivers ±24mA output current (IOL/IOH), as specified in Table 4-2 of the datasheet. This allows direct driving of multiple 74AC inputs or terminated 50Ω transmission lines without buffer amplification - verified under recommended operating conditions at TA = 25°C.
Can unused inputs on SN74AC86PWE4 be left floating?
No - all unused inputs on SN74AC86PWE4 must be tied to VCC or GND to prevent undefined logic states and increased power consumption. Section 7.2.1 explicitly mandates this, as floating CMOS inputs cause shoot-through current and potential oscillation due to intermediate voltage thresholds.
Is SN74AC86PWE4 pin-compatible with other 74AC86 variants in TSSOP-14?
Yes, SN74AC86PWE4 shares identical pinout, electrical characteristics, and footprint with all other SN74AC86 variants offered in PW (TSSOP-14) packaging - including SN74AC86PWR and SN74AC86PWR.A - as confirmed in Figure 3-1 and Table 3-1 of the SCAS533F datasheet.
