Nexperia USA Inc. 74HC86DB,118

Overview

74HC86DB,118 from Nexperia is a quad 2-input EXCLUSIVE-OR gate in SSOP14 (SOT337-1) package, operating from 2.0 V to 6.0 V supply, delivering propagation delay of 14 ns (typ.) at VCC = 4.5 V and CL = 50 pF, with CMOS-level inputs and ±25 mA output drive capability - used in digital logic arbitration, parity generation, and data path control in industrial microcontroller interfaces.

For engineers reviewing the 74HC86DB,118 datasheet, 74HC86DB,118 pinout, 74HC86DB,118 application, or 74HC86DB,118 equivalent, key selection criteria include input voltage compatibility (CMOS), temperature range (-40 °C to +125 °C), SO14/TSSOP14/SSOP14 package mapping, and dynamic power dissipation (CPD = 30 pF).

Technical Context

This device implements four independent XOR logic functions per package, each with symmetrical HIGH/LOW input thresholds referenced to VCC (VIH = 0.7×VCC, VIL = 0.3×VCC), enabling robust noise immunity in mixed-signal environments. Input clamp diodes allow safe interfacing to voltages exceeding VCC when current-limiting resistors are used.

It supports rail-to-rail output swing with VOH ≥ 4.4 V and VOL ≤ 0.26 V at VCC = 4.5 V and IO = ±4.0 mA, and exhibits latch-up immunity >100 mA per JESD78 Class II Level B - confirming suitability for reflow-soldered industrial PCBs requiring long-term reliability.

FAQ

What is the maximum clock frequency supported by 74HC86DB,118?

The device does not operate as a clocked sequential circuit but as combinational logic. Its usable toggle rate is limited by propagation delay: at VCC = 4.5 V and CL = 50 pF, tPD = 14 ns (typ.), supporting reliable operation up to ~35 MHz in feedback configurations. For guaranteed timing, use worst-case 36 ns (max) at -40 °C to +85 °C to derive maximum frequency.

Can 74HC86DB,118 interface directly with 3.3 V microcontrollers?

Yes - with VCC = 3.3 V, VIH(min) = 2.31 V and VIL(max) = 0.99 V per datasheet Table 6, fully compatible with standard 3.3 V CMOS I/O. Output VOH(min) = 3.15 V and VOL(max) = 0.26 V ensure noise margins >0.8 V, satisfying 3.3 V logic thresholds without level shifting.

Is 74HC86DB,118 pin-compatible with 74HCT86DB,118?

No - although both share identical pinout and package (SSOP14), 74HCT86DB,118 uses TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), whereas 74HC86DB,118 requires CMOS thresholds (VIH = 3.15 V min). Swapping them may cause logic misreads in mixed-voltage systems.

Does 74HC86DB,118 require external pull-up or pull-down resistors on unused inputs?

Yes - unused inputs must be terminated to VCC or GND to prevent floating nodes that cause increased ICC, oscillation, or EMI. The internal input leakage is ±0.1 μA (max), insufficient to guarantee stable logic levels; 10 kΩ resistors are recommended for noise immunity and power optimization.
