Nexperia USA Inc. HEF4082BT,652

Overview

HEF4082BT,652 from Nexperia is a dual 4-input CMOS AND gate in SO14 package, operating from 3.0 V to 15.0 V supply, delivering symmetrical output drive (±4.2 mA at 15 V), propagation delay as low as 25 ns at 15 V/50 pF, and full industrial temperature range (-40 °C to +125 °C). It serves as a logic-level combinatorial gate in power management sequencing, sensor interface signal conditioning, and industrial control state decoding.

For engineers reviewing the HEF4082BT,652 datasheet, HEF4082BT,652 pinout, HEF4082BT,652 application, or HEF4082BT,652 equivalent, this page delivers verified pin functions, real-world timing behavior across voltage/temperature, static/dynamic electrical specs, and validated alternatives for logic-level compatibility in legacy 4000-series designs.

Technical Context

The HEF4082BT,652 implements two independent 4-input AND gates using standard CMOS process technology, with input clamp diodes enabling safe interfacing to voltages exceeding VDD when used with current-limiting resistors. Its symmetrical output structure ensures matched rise/fall times (tTLH/tTHL ≤ 40 ns at 15 V) and rail-to-rail VOH/VOL performance (VOH ≥ 14.95 V, VOL ≤ 0.05 V at 15 V).

It complies with JEDEC JESD13-B and supports ESD robustness per JS-001 Class 2 (>2000 V HBM) and JS-002 Class C3 (>1000 V CDM). Static operation allows zero static current draw at DC, while dynamic power scales predictably via PD = 16800 × fi + Σ(fo × CL) × VDD² at 15 V.

FAQ

What is the maximum allowable input voltage relative to VDD?

The HEF4082BT,652 features internal input clamp diodes that allow safe operation with input voltages up to VDD + 0.5 V or VSS − 0.5 V, provided an external current-limiting resistor is used. Absolute maximum input voltage is −0.5 V to VDD + 0.5 V, with clamping current limited to ±10 mA per pin.

Can HEF4082BT,652 operate reliably at 3.3 V supply?

Yes - the device is fully specified from 3.0 V to 15.0 V. At 3.3 V, VIH is 2.3 V min and VIL is 1.0 V max, providing adequate noise margin. Propagation delay increases to ~125 ns (typical) at 3.3 V/50 pF, consistent with datasheet Table 7 extrapolation formula.

Are pins 6 and 8 internally connected or truly unused?

Pins 6 and 8 are designated "n.c." (no connection) in the official Nexperia datasheet and functional diagram. They are not bonded internally and must remain unconnected on the PCB. No trace, pad, or solder mask opening is required for these pins.

How does thermal derating affect power dissipation above 100 °C?

For the SOT108-1 package, total power dissipation (Ptot) derates linearly at 10.1 mW/K above 100 °C. At 125 °C ambient, Ptot is reduced from 500 mW to 475 mW (500 − (25 × 10.1)), ensuring safe junction temperature operation within rated limits.
