NXP Semiconductors 74LV86DB,112

Overview

74LV86DB,112 from Nexperia is a low-voltage Si-gate CMOS quad 2-input exclusive-OR gate operating from 1.0 V to 5.5 V supply, delivering 11 ns typical propagation delay at 3.3 V with 15 pF load, and specified for −40 °C to +125 °C industrial temperature range in SSOP14 package. It serves as a logic-level combinatorial function block in digital signal routing, parity generation, and arithmetic circuits.

For engineers reviewing the 74LV86DB,112 datasheet, 74LV86DB,112 pinout, 74LV86DB,112 application, or 74LV86DB,112 equivalent, this page delivers verified electrical parameters, validated pin mapping for SSOP14, real-world use cases in bus arbitration and error detection, and two confirmed alternative parts with documented functional and thermal differences.

Technical Context

The 74LV86DB,112 implements four independent XOR gates using low-threshold CMOS technology optimized for 1.0 V–3.6 V operation while maintaining TTL input level compatibility at VCC = 2.7 V–3.6 V. Its static characteristics include VIH = 2.0 V (min) and VOL = 0.25 V (max) at IO = 6 mA and VCC = 3.0 V.

Dynamic behavior is characterized by tpd = 11 ns (typ) at VCC = 3.3 V/CL = 15 pF, CPD = 30 pF, and ground bounce < 0.8 V at Tamb = 25 °C. ESD protection exceeds 2000 V HBM and 200 V MM per JESD22-A114E/A115-A.

FAQ

What is the maximum operating frequency supported by the 74LV86DB,112?

The 74LV86DB,112 does not specify a maximum clock frequency, as it is a combinational logic device with no internal clock. Its usable data rate depends on propagation delay and system timing margins: at VCC = 3.3 V and CL = 15 pF, tpd = 11 ns (typ), supporting reliable operation up to approximately 45 MHz in feedback-free paths. System-level timing analysis must account for trace delays and loading.

Does the 74LV86DB,112 require external pull-up or pull-down resistors on unused inputs?

Yes - unused inputs on the 74LV86DB,112 must be terminated to VCC or GND via resistors (typically 10 kΩ–100 kΩ) to prevent floating states that cause increased ICC, excessive power dissipation, and potential oscillation. The device has no internal input termination; unconnected inputs violate recommended operating conditions and may compromise noise immunity.

Can the 74LV86DB,112 drive a 50 pF capacitive load reliably at 3.3 V?

Yes - the 74LV86DB,112 maintains specified VOH/VOL performance driving up to 50 pF loads. At VCC = 3.3 V and IO = ±6 mA, VOL ≤ 0.40 V and VOH ≥ 2.4 V are guaranteed across −40 °C to +125 °C. Propagation delay increases to 13 ns (max) at CL = 50 pF, remaining within timing budgets for most medium-speed digital interfaces.

Is the 74LV86DB,112 pin-compatible with the 74HC86 and 74HCT86?

Yes - the 74LV86DB,112 is explicitly stated as pin and function compatible with 74HC86 and 74HCT86 in its general description. All share identical pinout (1A–4Y, GND, VCC), truth table, and logic function. However, voltage thresholds, speed, and drive strength differ: LV variants operate down to 1.0 V and exhibit faster tpd at low VCC, while HC/HCT require ≥ 2 V and have higher ICC.

What is the thermal resistance (RθJA) of the 74LV86DB,112 in its SSOP14 package?

The datasheet does not publish RθJA for the 74LV86DB,112 (SOT337-1). However, its maximum power dissipation is rated at 500 mW over −40 °C to +125 °C ambient, implying an effective RθJA ≈ 100 °C/W assuming 125 °C junction limit. For precise thermal design, users should apply JEDEC JESD51-2 compliant PCB layouts with 1 in² copper pour and thermal vias beneath the package body.
