Nexperia USA Inc. HEF4082BT-Q100J

Overview

HEF4082BT-Q100 from Nexperia is a dual 4-input AND 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, propagation delay as low as 25 ns at 15 V/50 pF, and CMOS-level static power dissipation. It serves as a logic combiner in automotive body control modules for multi-sensor enable gating.

For engineers reviewing the HEF4082BT-Q100 datasheet, HEF4082BT-Q100 pinout, HEF4082BT-Q100 application, or HEF4082BT-Q100 equivalent, key selection criteria include automotive-grade temperature margin, input clamping diode support for overvoltage-tolerant interfacing, symmetrical output drive (±4.2 mA at 15 V), and SO14 package compatibility with legacy 4000-series PCB footprints.

Technical Context

This device implements two independent 4-input AND functions using standard CMOS process technology, with fully static operation and no minimum clock or refresh requirement. Each gate features clamp diodes on all inputs, enabling safe interface to signals exceeding VDD when used with current-limiting resistors.

Logic behavior follows standard Boolean AND truth table: output is HIGH only when all four inputs are HIGH; otherwise LOW. Output characteristics are standardized and symmetrical-VOH ≥ 14.95 V and VOL ≤ 0.05 V at VDD = 15 V, supporting robust noise immunity in electrically noisy automotive environments.

FAQ

Is HEF4082BT-Q100 pin-compatible with CD4082BE?

Yes - HEF4082BT-Q100 uses the same SO14 (SOT108-1) footprint and identical pin configuration as CD4082BE, including VDD on pin 14, VSS on pin 7, and dual 4-input AND outputs on pins 1 and 13. No PCB redesign is needed for drop-in replacement in existing layouts.

Can HEF4082BT-Q100 interface directly with 24 V sensor signals?

Yes - its inputs include integrated clamp diodes to VDD and VSS, allowing safe interface to 24 V signals when used with appropriate current-limiting resistors (e.g., 10 kΩ), eliminating need for external level-shifting circuitry in body electronics applications.

What is the maximum output capacitive load supported at 125 °C?

At Tamb = +125 °C and VDD = 15 V, the device supports up to 50 pF load capacitance while maintaining tpd ≤ 45 ns and tTHL/tTLH ≤ 40 ns, per Table 7. Exceeding 50 pF increases propagation delay nonlinearly and may violate timing margins in high-speed gating paths.

Does HEF4082BT-Q100 require external pull-up or pull-down resistors on unused inputs?

No - unused inputs must be tied to VDD or VSS to prevent floating states and increased supply current; internal input leakage is ≤ ±1.0 μA at 15 V, so no external resistors are needed beyond the mandatory VDD/VSS connection for defined logic levels.
