ZSCT1555N8中文资料PRECISION SINGLE CELL TIMER数据手册Diodes规格书

描述 Description

DEVICE DESCRIPTION
These devices are precision timing circuits for generation of accurate time delays or oscillation. Advanced circuit design means that these devices can operate from a single battery cell with the minimum of quiescent current.
In monostable mode time delays are controlled by a single resistor and capacitor network. In astable mode the frequency and duty cycle can be accurately and independently controlled with two external resistors and one capacitor.
The threshold and trigger levels are normally set as a proportion of VCC by internal resistors. These levels can be programmed by the use of the control input pin.FEATURES
• 0.9V supply operating voltage guaranteed
• Pin connections comparable with 555 series timers
• Very low quiescent current 74 µA
• SO8 and DIL8 packages
• Operating temperature range compatible with battery technologiesAPPLICATIONS
• Portable and battery powered equipment
• Low voltage and low power systems
