NXP Semiconductors HEC4001BT,118

Overview

HEC4001BT,118 from Nexperia is a quad 2-input NOR gate logic IC operating across 3.0 V to 15.0 V supply, featuring CMOS low power dissipation, high noise immunity, and fully static operation. It delivers symmetrical output drive with VOH ≥ 4.95 V and VOL ≤ 0.05 V at VDD = 5 V, and supports industrial temperature range from −40 °C to +125 °C in SO14 package - used in digital control logic, reset generation, and enable/disable sequencing in embedded instrumentation.

For engineers reviewing the HEC4001BT,118 datasheet, HEC4001BT,118 pinout, HEC4001BT,118 application, or HEC4001BT,118 equivalent, key selection criteria include supply voltage flexibility (3–15 V), guaranteed operation up to +125 °C, input clamping diodes enabling overvoltage-tolerant interfacing, and JEDEC JESD13-B compliance for standardized logic behavior.

Technical Context

The HEC4001BT,118 implements four independent 2-input NOR gates using complementary metal-oxide semiconductor (CMOS) technology, ensuring zero static current draw and rail-to-rail output swing. Each gate exhibits identical input threshold symmetry and output sourcing/sinking capability, with VIH = 3.5 V and VIL = 1.5 V minimum at VDD = 5 V.

Its functional architecture includes integrated input clamp diodes referenced to VSS and VDD, allowing safe interface to signals exceeding supply rails when used with current-limiting resistors. Propagation delays scale predictably with load capacitance: tPHL/tPLH = 20–40 ns typical at VDD = 15 V and CL = 50 pF.

Key Specifications

FAQ

What is the maximum supply voltage rating for HEC4001BT,118?

The absolute maximum supply voltage (VDD) for HEC4001BT,118 is +18 V, though recommended operation is limited to 3.0 V to 15.0 V per datasheet Section 8. Exceeding 15.0 V continuously may compromise long-term reliability despite surviving short-term transients.

Does HEC4001BT,118 support operation at +125 °C ambient temperature?

Yes, HEC4001BT,118 is fully specified and tested for operation from −40 °C to +125 °C ambient temperature, as confirmed in Table 1 (Ordering Information) and Section 8 (Recommended Operating Conditions) of the Nexperia datasheet Rev. 12.

Are the inputs of HEC4001BT,118 protected against overvoltage conditions?

Yes, HEC4001BT,118 features integrated clamp diodes on all inputs (1A–4B), allowing safe interface to voltages up to VDD + 0.5 V or VSS − 0.5 V when used with appropriate current-limiting resistors - a key feature detailed in Section 1 and Table 4.

What is the typical propagation delay of HEC4001BT,118 at 15 V supply?

At VDD = 15 V and CL = 50 pF, the typical HIGH-to-LOW (tPHL) and LOW-to-HIGH (tPLH) propagation delays for HEC4001BT,118 are 20 ns and 20 ns respectively, per Table 7's extrapolation formula "12 + 0.16 × CL" and the "Typ" column values.

Is HEC4001BT,118 pin-compatible with other quad NOR gate ICs like CD4001BE?

Yes, HEC4001BT,118 shares identical SO14 pinout and logic function with CD4001BE, as verified by matching pin descriptions in Section 5.2 and functional diagrams in Figures 1–2 of both datasheets - enabling drop-in replacement where voltage and temperature requirements align.
