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 and oscillations

in both monostable and astable operation. It 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 200KΩ each)

that set the threshold and trigger levels at two-thirds and one-third

respectively of V

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. All

four timers share the same control and reset pins so that timing functions

are synchronized.

FEATURES

• High speed operation -- 2MHz typical oscillation at 5V

• Each discharge output sinking current: 40mA at 5V

• Guaranteed low operating supply voltage of 2 to 12V

• Each timer is functionally equivalent to NE555 with greatly expanded

• High speed, low power, monolithic CMOS technology

• Low supply current: 150µA typical

• Extremely low trigger, threshold and reset currents: 10pA typical

• Operates in both monostable and astable modes

• Fixed 50% duty cycle or adjustable duty cycle

• CMOS, NMOS and TTL compatible input/output

• Low supply current spikes
