ORDERING INFORMATION (“L” suffix denotes lead-free (RoHS))
GENERAL DESCRIPTION
The ALD1502/ALD2502 timers are high performance single/dual mono-
lithic timing circuits built with advanced silicon gate CMOS technology.
They offer the benefits of high input impedance, thereby allowing
smaller timing capacitors and a longer timing cycle; high speed, with
typical cycle time of 400ns; low power dissipation for battery operated
environment; reduced supply current spikes, allowing smaller and
lower cost decoupling capacitors.
Each timer is capable of producing accurate time delays and oscilla-
tions in both monostable and astable operation, and operates in the
one-shot (monostable) mode or 50% duty cycle free running oscillation
mode with a single resistor and one capacitor. The inputs and outputs
are fully compatible with CMOS, NMOS or TTL logic.
There are three matched internal resistors (approximately 200K
each) that set the threshold and trigger levels at two-thirds and one-third
respectively of V+. These levels can be adjusted by using the control
terminal. When the trigger input is below the trigger level, the output is
in the high state and sourcing 2mA. When the threshold input is above
the threshold level at the same time the trigger input is above the trigger
level, the internal flip-flop is reset, the output goes to the low state and
sinks up to 10mA. The reset input overrides all other inputs and when
it is active (reset voltage less than 1V), the output is in the low state.
FEATURES
High speed operation -- 2.5MHz typical oscillation at 5V
High discharge sinking current of 80mA at 5V
Guaranteed low operating supply voltage of 2V to 12V

Low supply current: 50A typical for ALD1502
and100A typical for ALD2502
Extremely low trigger, threshold and reset currents: 10pA typical
Operates in both monostable and astable modes
