Nexperia USA Inc. HEF4073BT,652

Overview

HEF4073BT,652 from Nexperia is a triple 3-input CMOS AND gate IC in SO14 package, operating from 3.0 V to 15.0 V supply, with propagation delays as low as 7 ns (VDD = 15 V, CL = 50 pF), ±10 mA output drive capability, and specified for -40 °C to +85 °C industrial temperature range. It serves as a logic-level combinational gate in digital control, interface conditioning, and power sequencing circuits.

For engineers reviewing the HEF4073BT,652 datasheet, HEF4073BT,652 pinout, HEF4073BT,652 application, or HEF4073BT,652 equivalent, key selection criteria include supply voltage flexibility (3–15 V), input clamping diodes enabling overvoltage-tolerant interfacing, guaranteed noise immunity, and SO14 footprint compatibility with legacy 4000-series logic designs.

Technical Context

The HEF4073BT,652 implements three independent 3-input AND functions using standard CMOS process technology, with inputs featuring integrated clamp diodes to ground and VDD for robustness against transient overvoltage. Each gate exhibits symmetrical HIGH/LOW propagation delay characteristics dependent on supply voltage and load capacitance.

Its static behavior is defined across full temperature range: VIH ≥ 11.0 V at VDD = 15 V, VOL ≤ 0.05 V at |IOL| ≤ 1 μA, and II input leakage ≤ ±1.0 μA at 15 V and +85 °C - ensuring reliable logic level interpretation in mixed-voltage systems.

FAQ

Can HEF4073BT,652 operate at 3.3 V?

Yes - the device is fully specified from 3.0 V to 15.0 V. At VDD = 3.3 V, VIH is guaranteed ≥2.2 V and VOL ≤0.05 V (|IOL| < 1 μA), meeting standard 3.3 V logic thresholds. Propagation delay increases to ~45 ns (typical) at 3.3 V with 50 pF load, consistent with datasheet extrapolation formulas.

Does HEF4073BT,652 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 power consumption. The datasheet explicitly prohibits leaving inputs unconnected due to CMOS gate susceptibility to noise-induced shoot-through current, even with internal clamp diodes present.

What is the maximum capacitive load the outputs can drive reliably?

The outputs are characterized up to 50 pF per gate (Table 10). Driving >50 pF increases propagation delay nonlinearly and may cause output transition time degradation. For loads >50 pF, buffer stages or lower VDD operation (to reduce slew rate) are recommended to maintain timing integrity and signal fidelity.

Is HEF4073BT,652 automotive qualified?

No - the device is rated for industrial temperature range (-40 °C to +85 °C) and carries no AEC-Q100 qualification. Nexperia explicitly states in its legal disclaimers that non-automotive qualified products are unsuitable for safety-critical or life-support applications, including automotive ECUs or ADAS subsystems.
