Detailed description
HEF4093BT IC
The HEF4093BT is a quad, two-input NAND logic gate with Schmitt-trigger inputs. This advanced CMOS 4000-series component is designed to provide maximum operational stability in circuits with slow-rising input signals or in high-noise environments. Thanks to its unique switching characteristics, the HEF4093BT forms the foundation for electronic projects that require precise digital signal processing and the elimination of contact bounce or pulse noise.
Key Features and Specifications of HEF4093BT
The HEF4093BT IC is distinguished by a very wide supply voltage range and high noise immunity, typical for CMOS technology. The Schmitt-trigger inputs allow for seamless conversion of slow (analog) signals into clean digital (square) signals.
The main technical parameters of the HEF4093BT are:
- Logic Function: Quad 2-input NAND gate.
- Supply Voltage (Vdd): Wide range from 3V to 15V (according to 4000B series standards).
- Input Type: Schmitt-trigger, providing voltage hysteresis for improved noise filtering.
- Output Current: Capable of driving low-current loads while maintaining full logic levels.
- Propagation Delay: Optimized for stability, typically ~60ns at 10V supply.
- Package: SO-14 (SOT108-1), designed for automated surface-mount (SMD) assembly.
These specific parameters make the HEF4093BT highly durable and ensure reproducible results in serial production of professional devices.
Typical Applications of HEF4093BT
Thanks to its ability to shape signals and operate over a wide voltage range, the HEF4093BT gate is used in many specialized circuits where standard logic gates might fail. The most common applications include:
- Pulse shaping circuits and RC waveform generators (oscillators),
- Contact debounce systems for buttons and mechanical switches,
- Input interfaces for slow-rising or noisy signal lines,
- Delay circuits and monostable/astable timing circuits,
- Industrial automation systems requiring high electromagnetic noise immunity.
The HEF4093BT available from Micros ensures stable logic operation even under challenging power conditions. Proper implementation of this IC allows for significant simplification of the signal path without compromising data processing quality.
