Product details

Overview

74HCT86D/C5J from NXP Semiconductors is a quad 2-input XOR gate IC in SO14 package, operating at 4.5–5.5 V supply, with typical propagation delay of 19 ns at 5 V and ±4 mA output drive capability. It performs logic-level exclusive-OR functions in digital control circuits for industrial PLC I/O modules.

For engineers reviewing the 74HCT86D/C5J datasheet, 74HCT86D/C5J pinout, 74HCT86D/C5J application, or 74HCT86D/C5J equivalent, key selection criteria include TTL-compatible input thresholds, CMOS-level output swing, fan-out capability, and guaranteed AC/DC parametric performance across commercial temperature range.

Technical Context

This device implements four independent XOR logic gates using high-speed silicon-gate CMOS technology. Each gate features buffered inputs and outputs, Schmitt-trigger noise immunity is not present, and the logic function conforms to IEEE Std 91-1984 standard truth table.

It operates strictly within the 74HCT family's input voltage compatibility (TTL-level 0.8 V / 2.0 V thresholds) while delivering rail-to-rail CMOS output levels. No internal pull-up/pull-down resistors are integrated, and all inputs tolerate 5.5 V regardless of V_CC.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Family	74HCT - TTL-compatible inputs, CMOS outputs, 5 V only operation
Supply Voltage	4.5 V to 5.5 V - Ensures stable operation under regulated 5 V rail with ±10% tolerance
Propagation Delay	19 ns max @ V_CC = 5 V, C_L = 50 pF - Supports ≤26 MHz toggle frequency in synchronous logic paths
Output Drive	±4 mA @ V_CC = 5 V - Drives one 74HC/74HCT input or two LS-TTL loads directly
Input Thresholds	V_IL = 0.8 V max, V_IH = 2.0 V min - Interoperates with legacy 74LS and microcontroller GPIO without level shifters
Operating Temp	−40 °C to +125 °C - Qualified for extended industrial ambient conditions

Pinout & Package

Package: SO14 (Small Outline, 14-pin, 150 mil width, 1.27 mm pitch).

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 4, 5, 8, 9, 11, 12	Input A/B per gate	Dedicated logic inputs for each of four XOR gates; no shared or multiplexed function
3, 6, 10, 13	Output Y per gate	CMOS push-pull outputs; no open-drain configuration or enable control
7	GND	Ground reference for all logic and power domains; single-point return required
14	V_CC	Positive supply terminal; must be decoupled locally with 100 nF ceramic capacitor

Key Features

Feature	Design Value
TTL-compatible input thresholds	Enables direct interface with 74LS, 74F, and MCU GPIO without external biasing or level translation
Guaranteed latch-up immunity	Withstands >200 mA transient current per IEC 61000-4-2 ESD test without functional disruption
High noise immunity	Input hysteresis absent, but VIH/VIL margins exceed 0.4 V at 5 V, supporting noisy industrial bus environments
Low dynamic power consumption	Typical ICC = 4 µA at 5 V static; increases only during switching - ideal for low-duty-cycle control logic

Applications

Industrial Control Logic

Microcontroller Peripheral Interface

Use Scenario: Detecting state changes in dual-channel encoder signals for motor direction sensing in servo drives.

IC Role / Device Role / Timing Role: XOR gate computes quadrature phase difference; propagation delay directly impacts minimum detectable edge rate.

Use Value: 19 ns delay enables reliable detection of encoder edges up to 26 MHz, matching common 1000-line incremental encoders at 15,000 RPM.

Use Scenario: Generating interrupt enable/disable flags by combining GPIO status bits in an ARM Cortex-M3-based HMI controller.

IC Role / Device Role / Timing Role: Performs real-time logic arbitration between two asynchronous input sources before feeding NVIC input.

Use Value: TTL-compatible inputs eliminate need for external pull-ups or voltage dividers, reducing BOM count and PCB area.

Data Path Parity Generation

Test Equipment Signal Conditioning

Use Scenario: Computing odd/even parity over 4-bit data buses in boundary-scan test controllers.

IC Role / Device Role / Timing Role: Four XOR gates cascade to generate single-bit parity output; timing stack-up is deterministic and bounded.

Use Value: Guaranteed 19 ns max delay per stage ensures total parity generation completes within 76 ns - sufficient for 10 MHz parallel bus cycles.

Use Scenario: Converting differential clock enable signals into single-ended active-high strobes for logic analyzers.

IC Role / Device Role / Timing Role: Acts as signal combiner for complementary enable lines; no internal inversion or buffering added.

Use Value: Rail-to-rail CMOS output swing ensures full logic '1' (≥4.4 V) at analyzer input, meeting NI-DAQ and Tektronix trigger threshold requirements.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74HCT86DR	Same logic function, SO14 package, identical AC/DC specs; TI part uses different die revision and thermal pad design	No functional impact in PCB-replaceable designs; thermal resistance differs by ≤3 °C/W	Select when sourcing from TI-authorized channels or requiring TI-specific qualification documentation
74VHC86M	Higher speed (7.5 ns typ), wider V_CC range (2–5.5 V), but input thresholds are CMOS (not TTL-compatible)	Requires level-shifting for legacy 74LS or 5 V MCU GPIO interfaces	Choose only if system uses pure CMOS signaling and demands sub-10 ns propagation delay

Compared with SN74HCT86DR and 74VHC86M, the 74HCT86D/C5J uniquely balances TTL interoperability, industrial temperature range, and predictable 19 ns timing - making it optimal for retrofitting legacy control systems without redesigning input conditioning.

FAQ

Is 74HCT86D/C5J compatible with 5 V TTL logic families?

Yes. The 74HCT86D/C5J features TTL-compatible input thresholds (V_IL ≤ 0.8 V, V_IH ≥ 2.0 V), allowing direct connection to 74LS, 74F, and other 5 V TTL outputs without level shifters or pull-up resistors. Its CMOS outputs swing rail-to-rail, ensuring robust high/low logic levels for downstream CMOS loads.

What is the maximum clock frequency supported by this XOR gate?

The 74HCT86D/C5J supports a maximum toggle frequency of approximately 26 MHz, derived from its 19 ns maximum propagation delay under standard load (50 pF). This applies to repetitive square-wave operation; actual usable frequency depends on board layout, capacitive loading, and supply stability - not a rated clock input.

Does this device include Schmitt-trigger inputs?

No. The 74HCT86D/C5J has standard CMOS input structure without hysteresis. Input transition thresholds are fixed at ~1.5 V (typical) with no built-in noise margin enhancement. For noisy environments, external RC filtering or dedicated Schmitt-trigger buffers (e.g., 74HCT14) must be used upstream.

Can 74HCT86D/C5J operate below 4.5 V?

No. The device is specified only for 4.5–5.5 V operation. Below 4.5 V, DC parameters such as V_OH, V_OL, and noise margins degrade beyond specification limits, and AC performance (propagation delay, transition time) becomes unpredictable. Operation outside this range is not guaranteed and may cause functional failure.
