Description

The BU4538B is a monostable multivibrator that can be reset and retriggered. BU4538B is triggered from either edge of an input pulse. As the output pulse width and accuracy are determined by the external timing constants Cx and Rx, a wide range of accurate output pulse widths is available. Linear CMOS technology makes it possible to control the output pulse width with greater accuracy. Determination is made based on t_WOUT = Rx · Cx throughout the entire power supply voltage range, eliminating the necessity for other coefficients.
