The CD14538BE logic device is classified as a multivibrator. Multivibrators are two-state devices that are capable of rapidly transitioning between those two states in response to an external stimuli. They are often used for signal conditioning, timekeeping, and other timing related applications.

The CD14538BE is a dual-monostable circuit with many features, including built-in Schmidt trigger circuits, low-power gate-drive circuit, and the ability to generate asymmetrical output pulses. It features active-low logic inputs, meaning that it will respond to logic low input signals.

The CD14538BE works by using two external capacitors (C1 and C2) and two external resistors (R1 and R2). An external voltage source is applied to the circuit, and its magnitudes is adjusted accordingly. When a low-level active signal (logic low) is applied to the device’s trigger input, the circuitry creates a voltage pulse that is recorded on C1, and another voltage pulse that is recorded on C2. These two voltage pulses create two distinct output states in the device, which can be used to perform timing operations. In addition, the circuit can generate asymmetrical output pulses when certain conditions are met.

The CD14538BE’s main application fields include timer circuits, pulse modulators, motor control, sequential timers, and frequency dividers. In addition, the device is frequently used in digital systems as an enable-checking element or as a data selector. Furthermore, the CD14538BE has been successfully used for automatic frequency control in specific radio applications, such as for FM radio stations.

Overall, the CD14538BE is an effective logic device for those looking for a low-power and compact circuit for performing timing and signal conditioning operations in a number of applications. Its active-low logic inputs, built-in Schmidt trigger circuits, and the ability to generate asymmetrical output pulses make it an ideal solution for a wide range of applications.
