Description

The BU4528B and BU4528BF are monostable multivibrators with trigger and reset functions that can be activated. Each chip has two built-in circuits.

Triggers BU4528BF can initiate both rising and falling in response to Input A and Input B. As the output monostable pulse width is determined by the time constant of the external resistance (Rx) and the capacitor (Cx), a wide range of output pulse widths can be set.

Setting the RESET input to "L" enables external asynchronous resetting and this RESET input can be utilized to reduce the time from the trigger disable input or the power on until the BU4528B and BU4528BF are ready for monostable operation.
