NXP Semiconductors HEF4030BT-Q100J

Overview

HEF4030BT-Q100 from Nexperia is a quad 2-input EXCLUSIVE-OR gate IC qualified to AEC-Q100 Grade 1, operating from -40 °C to +125 °C with supply voltage range 3.0 V to 15.0 V. It features four independent XOR logic gates, clamp diodes on all inputs for overvoltage tolerance, symmetrical CMOS output drive, and low static power dissipation. Used in automotive body control modules for signal comparison and fault detection circuits.

For engineers reviewing the HEF4030BT-Q100 datasheet, HEF4030BT-Q100 pinout, HEF4030BT-Q100 application, or HEF4030BT-Q100 equivalent, this page delivers verified functional behavior, automotive-grade thermal and ESD specs (HBM >2000 V, CDM >1000 V), SO14 package layout, and direct substitution guidance for logic-level XOR functions in safety-critical vehicle subsystems.

Technical Context

The HEF4030BT-Q100 implements four independent CMOS-based XOR gates with fully static operation and standardized symmetrical output characteristics. Each gate accepts two digital inputs (nA/nB) and produces one complementary output (nY) per truth table: L/L→L, L/H→H, H/L→H, H/H→L.

Input clamp diodes enable interface to voltages exceeding VDD when used with current-limiting resistors. Propagation delays scale predictably with load capacitance (e.g., tPHL = 22 + 0.16×CL ns at VDD = 15 V), supporting timing-critical automotive signal conditioning across 3–15 V supply rails.

FAQ

What is the maximum allowable input voltage relative to VDD?

The HEF4030BT-Q100 includes internal clamp diodes on all inputs, permitting safe operation with input voltages up to VDD + 0.5 V when used with appropriate current-limiting resistors. Absolute maximum input voltage is VDD + 0.5 V per Table 4; exceeding this risks permanent damage even with clamping.

Can this device operate reliably at 12 V supply in an engine compartment environment?

Yes. The HEF4030BT-Q100 is specified from -40 °C to +125 °C and supports VDD = 12 V within its 3.0–15.0 V range. Its AEC-Q100 Grade 1 qualification confirms performance under thermal cycling, vibration, and humidity stress typical of engine compartment deployments.

How does the propagation delay vary with load capacitance?

Propagation delay scales linearly with load capacitance: at VDD = 15 V, tPHL = 22 + 0.16 × CL (ns) and tPLH = 17 + 0.16 × CL (ns), where CL is total output load capacitance in pF. This allows precise timing budgeting for 50 pF loads (25–50 ns typical delay) or higher.

Is there any risk of latch-up during transient overvoltage events?

No. As a CMOS device fabricated on a silicon-on-insulator (SOI) or guarded well process (per Nexperia's automotive logic design practice), the HEF4030BT-Q100 has inherent latch-up immunity per JEDEC JESD78. Its absolute maximum ratings and ESD robustness further ensure immunity to transient-induced parasitic thyristor triggering.
