| CD4528BC Dual Monostable Multivibrator October 1987 Revised August 2000 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 Ordering Code: Order Number CD4528BCM CD4528BCN Package Number M16A N16E Package Description 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150 Narrow 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Devices also available in Tape and Reel. Specify by appending the suffix letter "X" to the ordering code.

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.
