仕様・特性

Revised April 2002 CD4538BC Dual Precision Monostable General Description Features The CD4538BC is a dual, precision monostable multivibrator with independent trigger and reset controls. The device is retriggerable and resettable, and the control inputs are internally latched. Two trigger inputs are provided to allow either rising or falling edge triggering. The reset inputs are active LOW and prevent triggering while active. Precise control of output pulse-width has been achieved using linear CMOS techniques. The pulse duration and accuracy are determined by external components RX and CX. The device does not allow the timing capacitor to discharge through the timing pin on power-down condition. For this reason, no external protection resistor is required in series with the timing pin. Input protection from static discharge is provided on all pins. s Wide supply voltage range: 3.0V to 15V s High noise immunity: 0.45 VCC (typ.) s Low power TTL compatibility: Fan out of 2 driving 74L or 1 driving 74LS s New formula: PWOUT = RC (PW in seconds, R in Ohms, C in Farads) s ±1.0% pulse-width variation from part to part (typ.) s Wide pulse-width range: 1 µs to ∞ s Separate latched reset inputs s Symmetrical output sink and source capability s Low standby current: 5 nA (typ.) @ 5 VDC s Pin compatible to CD4528BC Ordering Code: Order Number Package Number Package Description CD4538BCM M16A 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow CD4538BCWM M16B 16-Lead Small Outline Intergrated Circuit (SOIC), JEDEC MS-013, 0.300" Wide CD4538BCN N16E 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide Devices also available in Tape and Reel.
