CD4528BM/CD4528BC Dual Monostable Multivibrator General Description Features The CD4528B is a dual monostable multivibrator. Each device is retriggerable and resettable. Triggering can occur from either the rising or falling edge of an input pulse, resulting in an output pulse over a wide range of widths. Pulse duration and accuracy are determined by external timing components Rx and Cx. Y Y Y Y Y Y Wide supply voltage range 3.0V to 18V Separate reset available Quiescent current e 5.0 nA/package (typ.) at 5.0 VDC Diode protection on all inputs Triggerable from leading or trailing edge pulse Capable of driving two low-power TTL loads or one low-power Schottky TTL load over the rated temperature range Connection Diagrams Dual-In-Line Package TL/F/5998 – 2 Top View Order Number CD4528B TL/F/5998 – 1 Truth Table Inputs Clear L X X H H C1995 National Semiconductor Corporation A Outputs B X H X L v u H TL/F/5998 X X L Q L L L É É Q H H H ß ß H e High Level L e Low Level u v e Transition from Low to High e Transition from High to Low É e One High Level Pulse ß e One Low Level Pulse X e Irrelevant RRD-B30M105/Printed in U.
