NLV14538BDTR2G

Overview

The NLV14538BDTR2G is a dual precision retriggerable and resettable monostable multivibrator manufactured by onsemi. It operates within a supply voltage range of 3.0 Vdc to 18 Vdc and supports an output pulse width range from 10 nanoseconds to 10 seconds, determined by external timing components RX and CX. The device features latched trigger inputs and separate latched reset inputs, allowing triggering from either the positive edge (A input) or negative-going edge (B input). It is housed in a TSSOP-16 package and is qualified under AEC-Q100 standards.
