D A Load Current of 200mA is Achievable
D Capable of Directly Driving DTL and TTL Circuits
D Good Temperatue Stability (Typically 50ppm/°C)
D Good Supply Voltage Stability (Typically 0.1%/V)
Applications:
D Delay Timers
D Monostable Multivibrators
D Astable Multivibrators
D Pulse Generators
D Dividers
D Sequence Timers
