CD74HC4538E (74HC4538) multivibrator

Description:

The CD74HC4538E IC includes two monostable multivibrator circuits, each with a trigger input (A and B), an output (Q), and timing components (R and C) to set the pulse width. Monostable multivibrators, also known as one-shots, generate a single output pulse of a specified duration in response to an input trigger. This IC is designed for high-speed operation and low power consumption, making it suitable for precise timing applications.
