Nexperia USA Inc. HEF4082BT,653

Overview

HEF4082BT,653 from Nexperia is a dual 4-input CMOS AND gate in SO14 package, operating from 3.0 V to 15.0 V supply, with symmetrical output drive (±4.2 mA at 15 V), propagation delay as low as 25 ns (15 V, CL = 50 pF), and specified for -40 °C to +125 °C industrial temperature range. It enables logic-level translation and signal gating in mixed-voltage digital control subsystems.

For engineers reviewing the HEF4082BT,653 datasheet, HEF4082BT,653 pinout, HEF4082BT,653 application, or HEF4082BT,653 equivalent, this device supports high-noise-immunity combinational logic in power management sequencers, industrial PLC I/O modules, and legacy 4000-series system upgrades requiring dual independent 4-input AND functions.

Technical Context

The HEF4082BT,653 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. Each gate outputs a single HIGH only when all four inputs are HIGH, per truth table L/H/X logic states.

It features fully static operation, JEDEC JESD13-B compliance, and ESD protection rated to 2000 V HBM and 1000 V CDM. The device delivers standardized symmetrical output characteristics across its full 3–15 V supply range and operates reliably under continuous ambient temperatures up to +125 °C.

FAQ

Can HEF4082BT,653 operate at 3.3 V?

Yes - the device is fully specified down to 3.0 V supply voltage. At 3.3 V, VIH is 2.3 V min and VOL is 0.05 V max (IOL = 1.1 mA), supporting reliable interfacing with 3.3 V microcontrollers and FPGAs. Propagation delay increases to approximately 125 ns (CL = 50 pF), which remains adequate for most control logic applications.

Are pins 6 and 8 internally connected?

No - pins 6 and 8 are explicitly designated as "n.c." (not connected) in the official Nexperia datasheet. They are unconnected to any internal circuitry and must remain electrically floating. Tying them to VDD or VSS is unnecessary and may risk unintended coupling; best practice is to leave them unconnected on the PCB.

Does HEF4082BT,653 support mixed-voltage inputs (e.g., 5 V inputs with 3 V supply)?

No - inputs must remain within VSS −0.5 V to VDD +0.5 V. With VDD = 3 V, a 5 V input exceeds the absolute maximum VI limit (+3.5 V) and risks damage. However, the built-in input clamp diodes allow safe 5 V inputs *if* a series current-limiting resistor is used to restrict IIK to ≤ ±10 mA, as confirmed in Table 4 of the datasheet.

What is the maximum capacitive load the outputs can drive?

The outputs are characterized up to 50 pF (per Table 7), but the device can drive larger loads with increased propagation delay. For example, at 15 V and CL = 100 pF, tpd rises to ~55 ns (extrapolated from tpd = 17 + 0.16 × CL). Total power dissipation must also be checked: dynamic power scales with Σ(fo × CL) × VDD², so sustained high-frequency driving of >100 pF loads may exceed the 500 mW package limit.
