QUAD PRECISION HIGH SPEED MICROPOWER TIMER
ALD4501
GENERAL DESCRIPTION
The ALD4501 timer is a high performance QUAD monolithic timing circuit built with advanced silicon gate
CMOS technology.
It offers the benefits of high input impedance, thereby allowing smaller timing
capacitors and longer timing cycle; high speed with typical cycle time of 500ns; low power dissipation for battery operated environment; and reduced supply current spikes allowing smaller and lower cost decoupling
capacitors.
Each of the four timers can be independently operated in either the monostable, astable, or 50% duty cycle mode.
Each timer is capable of producing accurate time delays a...
