Nexperia USA Inc. 74HCT86D-Q100,118

Overview

74HCT86D-Q100,118 from Nexperia is an automotive-grade quad 2-input XOR gate IC with TTL-compatible inputs, operating from 4.5 V to 5.5 V, delivering propagation delay of 17–48 ns (VCC = 4.5 V), output drive capability of ±4.0 mA, and qualified per AEC-Q100 Grade 1 (−40 °C to +125 °C). It performs logic comparison and parity generation in vehicle body control modules.

For engineers reviewing the 74HCT86D-Q100,118 datasheet, 74HCT86D-Q100,118 pinout, 74HCT86D-Q100,118 application, or 74HCT86D-Q100,118 equivalent, key selection criteria include input voltage compatibility (TTL-level), automotive temperature range compliance, SO14 package mechanical fit, and XOR functional integrity under ESD stress (HBM >2000 V).

Technical Context

This device implements four independent CMOS-based exclusive-OR gates with input clamp diodes enabling safe interfacing to voltages exceeding VCC when used with current-limiting resistors. Each gate follows the truth table L/L→L, L/H→H, H/L→H, H/H→L.

It operates within two distinct logic families: 74HCT variant accepts TTL-level inputs (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 5 V), while maintaining CMOS output swing (VOH ≥ 3.98 V, VOL ≤ 0.26 V at IO = ±4.0 mA), ensuring interoperability with legacy 5 V TTL systems.

FAQ

What is the maximum clock frequency supported by 74HCT86D-Q100,118?

The 74HCT86D-Q100,118 is a combinational logic gate-not a clocked device-so it has no defined clock frequency. Its usable toggle rate depends on propagation delay and system-level timing margins; with tpd ≤ 48 ns, it reliably supports data rates up to ~10 MHz in cascaded or feedback-free paths under typical load conditions.

Can 74HCT86D-Q100,118 interface directly with 3.3 V microcontrollers?

No-its TTL-compatible inputs require VIH ≥ 2.0 V, which is met by 3.3 V logic, but its minimum VCC is 4.5 V. Operating below 4.5 V violates recommended conditions and risks unreliable VOH/VOL levels. A level-shifter or 5 V supply rail is required for interfacing.

Does this device support hot insertion or live insertion into powered systems?

No-74HCT86D-Q100,118 lacks hot-swap protection circuitry. Applying VCC after signal inputs may forward-bias internal clamp diodes, causing excessive current. Power sequencing must ensure VCC is stable before applying input signals.

How does the input clamp diode affect design of pull-up/pull-down networks?

The internal clamp diodes allow safe connection to voltages up to VCC + 0.5 V when series current-limiting resistors ≥ 1 kΩ are used. Pull-up resistors to 5 V are acceptable if VCC = 5 V, but pull-downs must reference GND-not a negative rail-as the lower clamp diode is tied to GND.
