CD4528BC Dual Monostable Multivibrator
General Description
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.
Features
s Wide supply voltage range: s Separate reset available s Quiescent current = 5.0 nA/package (typ.) at 5.0 VDC s Diode protection on all inputs s Triggerable from leading or trailing edge pulse s Capable of driving two low-power TTL loads or one lowpower Schottky TTL load over the rated temperature range 3.0V to 18V

Note 1: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. Except for “Operating Temperature Range”, they are not meant to imply that the devices should be operated at these limits. The table of “Electrical Characteristics” provides conditions for actual device operation. Note 2: VSS = 0V unless otherwise specified.
