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
■Wide supply voltage range: 3.0V to 18V
■Separate reset available
■Quiescent current = 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 lowpower Schottky TTL load over the rated temperature range
