CD4093BM96G4 - CMOS Quad 2-Input NAND Schmitt Trigger | TI
MPN: CD4093BM96G4 ✓ Hoạt độngCD4093BM96G4 Tóm tắt
A Schmitt trigger is a comparator circuit with hysteresis that converts noisy or slowly changing input signals into clean digital outputs. In the CD4093B, each gate switches at different thresholds for positive-going (VP) and negative-going (VN) signals, with the difference (hysteresis) ensuring stable switching and preventing multiple transitions. This makes the CD4093B ideal for interfacing with sensors, switches, and other real-world signals that may have slow edges or noise.
Key features of the CD4093BM96G4 include a wide supply voltage range of 3V to 18V, low quiescent current of typically 4µA, and output drive capability of 3.4mA sink and source. The Schmitt trigger inputs provide hysteresis of typically 0.9V at 5V supply, improving noise margin. The device is fully static, allowing operation at any frequency from DC to several MHz, and is pin-compatible with the standard CD4093B family.
The CD4093B is fabricated using silicon-gate CMOS technology, which provides low power dissipation and high noise immunity. The Schmitt trigger action is implemented using a feedback network that creates the hysteresis window. This architecture allows the device to operate reliably in noisy environments and to condition signals with slow rise/fall times, such as those from RC oscillators or mechanical switches.
Typical applications include waveform shaping, pulse generation, debouncing of mechanical switches, and as an oscillator in RC timing circuits. The CD4093BM96G4 is also used in sensor signal conditioning, where its hysteresis prevents false triggering. Its wide operating voltage range makes it suitable for both 5V and 3.3V logic systems, as well as higher-voltage industrial controls.
When designing with the CD4093BM96G4, ensure that input voltages do not exceed the supply rails, and consider adding a series resistor to limit input current if the input may exceed the supply. The Schmitt trigger inputs eliminate the need for external hysteresis components, simplifying circuit design. For high-speed applications, note that propagation delay is typically 80ns at 5V, which is adequate for most control and timing functions.

Bảo phân biệt quan trọng
- Wide supply voltage range of 3V to 18V (vsMC14093BDR2G)

Ghi chú thiết kế
The CD4093BM96G4 operates over a wide supply range of 3V to 18V. Ensure that the supply voltage does not exceed the absolute maximum rating of 20V. Decouple the VDD pin with a 0.1µF ceramic capacitor placed close to the device to filter high-frequency noise. The low quiescent current of 4µA makes it suitable for battery-powered applications, but consider the total current draw of all gates when calculating battery life.
For optimal performance, place the CD4093BM96G4 on a PCB with a solid ground plane. Keep input traces short to minimize noise pickup, especially in high-impedance circuits. The Schmitt trigger inputs provide hysteresis, but external noise can still cause issues if traces are excessively long. Use 0.1µF bypass capacitors on the power pins and consider series resistors on inputs if they are connected to long cables.
Do not leave unused inputs floating, as CMOS inputs can oscillate and increase power consumption. Tie unused inputs to VDD or VSS. Also, ensure that input voltages do not exceed the supply rails; if they might, add a series resistor to limit current. The Schmitt trigger inputs eliminate the need for external hysteresis components, but be aware that the hysteresis voltage varies with supply voltage (e.g., 0.9V at 5V, 2.3V at 15V).
