NXP Semiconductors HEF4070BP,652

Overview

HEF4070BP,652 from Nexperia is a quad 2-input CMOS EXCLUSIVE-OR gate in SO14 (SOT108-1) package, rated for -40 °C to +85 °C operation, with 5 V/10 V/15 V parametric support and input clamp diodes enabling overvoltage-tolerant interfacing. It delivers symmetrical output drive, high noise immunity, and JEDEC JESD13-B compliance for logic-level comparison and parity generation in industrial control and data integrity circuits.

For engineers reviewing the HEF4070BP,652 datasheet, HEF4070BP,652 pinout, HEF4070BP,652 application, or HEF4070BP,652 equivalent, key selection criteria include supply voltage flexibility (3–15 V), propagation delay down to 25 ns at 15 V, static power dissipation under 4 μA at 15 V, and ESD robustness (HBM >2000 V, CDM >1000 V).

Technical Context

The HEF4070BP,652 implements four independent XOR gates using standard CMOS logic architecture with fully static operation and symmetrical VOH/VOL characteristics. Each gate accepts two digital inputs and produces one true-output based on exclusive-OR truth table behavior (L/L→L, L/H→H, H/L→H, H/H→L).

Input clamp diodes allow safe interface to signals exceeding VDD when used with current-limiting resistors. The device operates across three supply rails (5 V, 10 V, 15 V) with guaranteed VIH/VIL thresholds and output drive capability up to ±3.6 mA at 15 V, supporting mixed-voltage system integration.

FAQ

What is the maximum supply voltage rating for HEF4070BP,652?

The HEF4070BP,652 has an absolute maximum supply voltage (VDD) of +18 V, but its recommended operating range is 3 V to 15 V. Operation at 15 V is fully characterized across temperature and load conditions, while 18 V is a stress limit beyond which permanent damage may occur. Always observe the 15 V upper bound for functional reliability in the HEF4070BP,652.

Does HEF4070BP,652 support direct interfacing with 12 V signals?

Yes - the HEF4070BP,652 integrates input clamp diodes that allow safe connection to voltages up to VDD + 0.5 V. When powered at 5 V or higher, a series current-limiting resistor (e.g., 10 kΩ) enables direct interface with 12 V control signals without external protection, as confirmed in the Functional Description and Limiting Values sections of the HEF4070BP,652 datasheet.

Is HEF4070BP,652 pin-compatible with 74HC86D?

No - although both are quad 2-input XOR gates in SO14 packages, the HEF4070BP,652 and 74HC86D have identical pinouts (1A–4Y, VSS, VDD), but differ critically in electrical behavior: HEF4070BP,652 supports 3–15 V operation with clamp diodes, while 74HC86D is rated only for 2–6 V and lacks clamps. Direct substitution is unsafe above 6 V; verify supply and signal levels before interchanging the HEF4070BP,652 and 74HC86D.

What is the typical propagation delay of HEF4070BP,652 at 5 V?

At VDD = 5 V and CL = 50 pF, the HEF4070BP,652 exhibits typical propagation delays of 75 ns (tPLH) and 85 ns (tPHL), with maximum values of 150 ns and 175 ns respectively. These values are measured from input transition (10%–90%) to output transition (50% level), per the Dynamic Characteristics section of the HEF4070BP,652 datasheet.

Does HEF4070BP,652 require external pull-up or pull-down resistors on unused inputs?

Yes - unused inputs of the HEF4070BP,652 must be terminated to either VDD or VSS to prevent floating nodes, which can cause increased supply current, erratic switching, or localized heating. CMOS inputs have high impedance; leaving them unconnected risks metastability and EMI susceptibility. This requirement applies uniformly across all four XOR gates in the HEF4070BP,652.
