ADVANCED LINEAR ALD4501 DEVICES, INC. QUAD PRECISION HIGH SPEED MICROPOWER TIMER GENERAL DESCRIPTION APPLICATIONS. The ALD4501 timer is a high performance QUAD monolithic timing High speed one-shot (monostable) circuit built with advanced silicon gate CMOS technology. It offers the pulse generation benefits of high input impedance, thereby allowing smaller timing Precision timing capacitors and longer timing cycle high speed with typical cycle time of Sequential timing 500ns low power dissipation for battery operated environment and Long delay timer reduced supply current spikes allowing smaller and lower cost decoupling Pulse width and pulse position capacitors. Each of the four timers can be independently operated in modulation either the monostable, astable, or 50% duty cycle mode. Missing pulse detector Frequency divider Each timer is capable of producing accurate time delays and oscillations Synchronized timer 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. PIN CONFIGURATION There are three matched internal resistors (approximately 200K each) that set the threshold and trigger levels at two-thirds and one-third RST 1 20 V+ + 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 DSC 2 19 OUT 1 1 in the high state and sourcing 2mA. When the threshold input is above TRIG 3 18 THRES 1 1 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 DSC 4 17 OUT 2 2 sinks up to 10mA. The reset input overrides all other inputs and when TRIG 5 16 THRES it is active (reset voltage less than 1V), the output is in the low state. All 2 2 four timers share the same control and reset pins so that timing functions DSC 6 15 OUT 3 3 are synchronized.
