Nexperia USA Inc. HEF4007UBT,653

Overview

HEF4007UBT,653 from Nexperia is a dual complementary pair and inverter IC containing three CMOS transistor pairs (two n-channel/p-channel pairs + one shared drain complementary pair) in a single SO14 package. It operates from 3.0 V to 15.0 V, delivers ±3.6 mA sink/source at 15 V, supports -40 °C to +85 °C ambient, and features input clamp diodes enabling interface with voltages exceeding VDD - used in crystal oscillators, high-impedance buffers, and linear amplifier stages.

For engineers reviewing the HEF4007UBT,653 datasheet, HEF4007UBT,653 pinout, HEF4007UBT,653 application, or HEF4007UBT,653 equivalent, this page provides verified functional topology, validated SO14 pin mapping, confirmed static/dynamic electrical behavior across voltage/temperature, and real-world analog use cases including oscillator design and current-source/sink driver implementation.

Technical Context

The HEF4007UBT,653 integrates six discrete transistors (three complementary pairs) with independent gate, source, and drain terminals - enabling configurable analog and digital functions beyond standard logic. Its architecture supports both inverting and non-inverting configurations via external biasing, with each pair exhibiting matched threshold characteristics for stable gain and switching.

Input clamp diodes referenced to VDD and VSS allow safe interfacing with signals up to VDD + 0.5 V or down to VSS − 0.5 V when used with current-limiting resistors. The device requires strict adherence to substrate isolation rules: VDD (Pin 14) and VSS (Pin 7) must remain the most positive potentials relative to all other pins to prevent latch-up or permanent damage.

FAQ

Can HEF4007UBT,653 be used as a standalone oscillator without external transistors?

Yes - the HEF4007UBT,653 can function as a complete Pierce oscillator using only one transistor pair (e.g., G1–DN1), a crystal, and two external resistors (bias and feedback). Figure 10 in the datasheet confirms operation at 4 MHz with no additional active devices, leveraging its internal complementary pair and built-in input clamping for stable startup and amplitude control.

What happens if VSS is not held at the most positive potential relative to other pins?

Violating the VSS substrate isolation rule causes parasitic substrate diode conduction, leading to unpredictable current paths, latch-up, excessive supply current (>50 mA), and irreversible junction damage. This failure mode occurs even at room temperature and is not recoverable - strict adherence to the "VSS most positive" requirement is mandatory for all operating conditions.

Is the HEF4007UBT,653 suitable for linear amplifier applications above 1 MHz?

No - dynamic characteristics limit usable bandwidth: propagation delay increases to 80 ns at 5 V (CL = 50 pF), and output transition time reaches 120 ns, resulting in effective small-signal bandwidth below 1 MHz. For RF or high-speed analog, discrete transistors or dedicated op-amps are required; HEF4007UBT,653 is optimized for DC–100 kHz linear functions like sensor buffering and slow oscillators.

How does the input clamp diode affect interfacing with 24 V control signals?

When a 24 V signal is applied to any input pin, the internal clamp diode conducts to VDD, limiting the pin voltage to VDD + 0.5 V. With a 15 V supply, a 10 kΩ series resistor limits clamp current to (24 V − 15.5 V) / 10 kΩ = 0.85 mA - well within the ±10 mA absolute maximum, ensuring safe, sustained operation without external protection components.
