KA556
KA556 is Dual Timer manufactured by Fairchild Semiconductor.
Features - - - - - - - Replaces Two KA555 Timers Operates in Both Astable And Monostable Modes High Output Current TTL patible Timing From Microsecond To Hours Adjustable Duty Cycle Temperature Stability Of 0.005% Per °C Description The KA556 series dual monolithic timing circuits are a highly stable controller capable of producing accurate time delays or oscillation. The KA556 is a dual KA555. Timing is provided an external resistor and capacitor for each timing function. The two timers operate independently of each other, sharing only VCC and ground. The circuits may be triggered and reset on falling waveforms. The output structures may sink or source 200m A. 14-DIP 14-SOP Applications - - - - - - - - - - Precision Timing Pulse Shaping Pulse Width Modulation Frequency Division Traffic Light Control Sequential Timing Pulse Generator Time Delay Generator Touch Tone Encoder Tone Burst Generator Internal Block Diagram Rev. 1.0.0 ©2001 Fairchild Semiconductor Corporation Absolute Maximum Ratings (TA = 25°C) Parameter Supply Voltage Lead Temperature (soldering 10sec) Power Dissipation Operating Temperature Range KA556 Storage Temperature Range Symbol VCC TLEAD PD TOPR TSTG Value 16 300 600 0 ~ + 70 - 65 ~ + 150 Unit V °C m W °C °C Electrical Characteristics (TA = 25°C, VCC = 5 ~ 15V, unless otherwise specified) Parameter Supply Voltage Supply Current - 1(two timers) (low state) Timing Error - 2(monostable) Initial Accuracy Drift with Temperature Drift with Supply Voltage Control Voltage Threshold Voltage Threshold Current- 3 Trigger Voltage Trigger Current Reset Voltage- 5 Reset Current Symbol VCC ICC ACCUR ∆t/∆T ∆t/∆VCC VC VTH ITH VTR ITR VRST IRST VCC = 15V VCC = 5V VTR = 0V VCC = 15V ISINK = 10m A ISINK = 50m A ISINK = 100m A ISINK = 200m A VCC = 5V ISINK = 8m A ISINK = 5m A VCC = 15V ISOURCE = 200m A ISOURCE = 100m A VCC = 5V ISOURCE = 100m A Rise Time of Output Fall Time of Output Discharge Leakage Current Matching Characteristics- 4 Initial Accuracy...
