Diodes Incorporated 74HC86T14-13

Overview

74HC86T14-13 from Diodes Incorporated is a quad 2-input XOR gate IC in TSSOP-14 package, operating from 2.0V to 6.0V supply, delivering 4mA output drive at 4.5V, with Schmitt-trigger inputs and CMOS-level power efficiency. It implements Boolean Y = A ⊕ B across four independent channels for digital logic decision paths in interface and control subsystems.

For engineers reviewing the 74HC86T14-13 datasheet, 74HC86T14-13 pinout, 74HC86T14-13 application, or 74HC86T14-13 equivalent, key selection criteria include input hysteresis margin, propagation delay consistency across V_CC range, output drive capability under load, and TSSOP-14 thermal and layout compatibility in space-constrained PCB designs.

Technical Context

This device implements four identical, electrically isolated XOR gates with push-pull outputs and Schmitt-trigger inputs-ensuring noise immunity on slow-rising or noisy signal lines. Each gate accepts two CMOS-compatible inputs and produces a single true-complement output per Boolean Y = A·B̅ + Ā·B.

It operates across industrial temperature (–40°C to +125°C) with propagation delays as low as 7ns (typ.) at 6.0V and CL = 50pF, and maintains VIH/VIL thresholds tightly specified across 2.0V–6.0V supply range-enabling interoperability with mixed-voltage logic domains.

Key Specifications

FAQ

What is the maximum clock frequency supported by the 74HC86T14-13?

The 74HC86T14-13 is a combinational logic device with no internal clock; its usable toggle rate depends on propagation delay and load. With t_PD ≤23ns (max @125°C, V_CC = 6.0V, C_L = 50pF), it reliably supports signal frequencies up to ~20MHz in typical PCB environments. Higher rates require careful layout and reduced capacitive loading.

Can unused inputs be left floating?

No. Unused inputs must be tied to V_CC or GND per Diodes' Recommended Operating Conditions. Floating inputs cause increased ICC, erratic output behavior, and potential latch-up due to undefined input voltage violating the Schmitt-trigger threshold window. A 10kΩ pull-up or pull-down resistor is acceptable for uncommitted pins.

Does the 74HC86T14-13 support mixed-voltage operation between inputs and V_CC?

No. All inputs must remain within 0V to V_CC, per Absolute Maximum Ratings. Applying 5V inputs to a 3.3V-powered device violates VI limits and risks damage. For mixed-voltage interfacing, use level-shifting buffers or select a dual-supply logic family like 74LVC.

Is the TSSOP-14 package RoHS and halogen-free?

Yes. The 74HC86T14-13 is fully RoHS 2 compliant (2011/65/EU) with no purposely added lead, and certified "Green" per Diodes' definition: Br < 900ppm, Cl < 900ppm (Br+Cl < 1500ppm), Sb < 1000ppm. Full compliance documentation is available via Diodes' website under part-specific environmental reports.
