NXP Semiconductors HEC4001BT,112

Overview

HEC4001BT,112 from Nexperia is a quad 2-input NOR gate IC operating across 3.0 V to 15.0 V supply, delivering symmetrical CMOS output drive with propagation delays as low as 20 ns at 15 V and 50 pF load, specified for -40 °C to +125 °C ambient operation, and used in digital logic interfacing, level translation, and control signal conditioning in industrial PLCs and power management sequencers.

For engineers reviewing the HEC4001BT,112 datasheet, HEC4001BT,112 pinout, HEC4001BT,112 application, or HEC4001BT,112 equivalent, key selection criteria include supply voltage range compatibility (3–15 V), guaranteed operation at +125 °C, SO14 package footprint, input clamping diode support for overvoltage-tolerant interfacing, and static logic-level performance with VIH/VIL thresholds defined per VDD.

Technical Context

The HEC4001BT,112 implements four independent 2-input NOR gates using standard CMOS process technology, each with fully static operation and no minimum clock or refresh requirement. Inputs feature integrated clamp diodes enabling safe interface to signals exceeding VDD when used with current-limiting resistors.

It complies with JEDEC JESD13-B and supports three parametric voltage grades (5 V, 10 V, 15 V), with output characteristics standardized for predictable fan-out and noise margin. ESD protection meets HBM >2000 V and CDM >1000 V per ANSI/ESDA/JEDEC JS-001 and JS-002.

FAQ

What is the maximum supply voltage rating for HEC4001BT,112?

The absolute maximum supply voltage (VDD) for HEC4001BT,112 is +18 V, but the recommended operating range is 3.0 V to 15.0 V per datasheet Table 4 and Table 5. Operation above 15 V voids parametric guarantees and risks accelerated aging; sustained use at 18 V is limited to transient conditions only.

Does HEC4001BT,112 support operation at +125 °C ambient temperature?

Yes, HEC4001BT,112 is fully specified and tested for operation from -40 °C to +125 °C ambient temperature, with all static and dynamic parameters guaranteed across this full range per Table 5 and Table 9. No derating is required for supply current or propagation delay at maximum temperature.

Are input clamp diodes present on all four gates of HEC4001BT,112?

Yes, all eight inputs (1A, 1B, 2A, 2B, 3A, 3B, 4A, 4B) of HEC4001BT,112 include integrated clamp diodes to both VSS and VDD, enabling safe interface to signals exceeding VDD when used with appropriate current-limiting resistors - a key feature confirmed in Section 1 and Table 2 of the datasheet.

What is the typical propagation delay of HEC4001BT,112 at 5 V supply?

At VDD = 5 V and CL = 50 pF, the typical HIGH-to-LOW (tPHL) and LOW-to-HIGH (tPLH) propagation delays for HEC4001BT,112 are 60 ns and 50 ns respectively, per Table 7. These values scale linearly with load capacitance using the formula tPHL = 33 + 0.55 × CL (ns).

Is HEC4001BT,112 pin-compatible with other SO14 quad NOR gate ICs?

HEC4001BT,112 uses the industry-standard SO14 pinout defined in SOT108-1: VSS on pin 7, VDD on pin 14, and gate inputs/outputs arranged as shown in Figure 1 and Table 2. It matches the pin configuration of CD4001B and HEF4001B variants, but differs from 74-series logic (e.g., 74HC02) which places VDD on pin 14 and VSS on pin 7 but assigns different signal functions to pins 1–6 and 8–13.
