ADVANCED LINEAR ALD7555/ALD7556 DEVICES, INC. SINGLE/DUAL CMOS ANALOG RC TIMER GENERAL DESCRIPTION BENEFITS Saves battery power The ALD7555/ALD7556 timers are high performance single/dual mono- Eliminates additional buffer lithic analog RC timing circuits. They offer significantly upgraded perfor- Smaller, lower cost capacitor mance in speed, leakage currents, supply current, stability, temperature voltage stability, and discharge output drive when compared to SE555/ Extended range of time constants NE555,ICL7555, TLC555, and ICM7555. APPLICATIONS The ALD7555/ALD7556 offer the benefits of high input impedance, thereby High speed one-shot (monostable) allowing smaller timing capacitors and a longer timing cycle high speed Precision sequential timing low power dissipation for battery operated environment reduced supply Long delay timer current spikes, allowing smaller and lower cost decoupling capacitors. Pulse width and pulse position modulation Missing pulse detector Each timer is capable of producing accurate time delays and oscillations in both monostable and astable operation, and operates in the one-shot Frequency divider (monostable) mode or 50% duty cycle free running oscillation mode with a Synchronized timer single resistor R and one capacitor C. The inputs and outputs are fully compatible with CMOS, NMOS or TTL logic. PIN CONFIGURATION There are three matched internal resistors (approximately 200K each) ALD7555 that set the threshold and trigger levels at two-thirds and one-third respec- + tively of V . These levels can be adjusted by using the control terminal. GND 1 8 V+ When the trigger input is below the trigger level, the output is in the high TRIG 2 7 DISC state and sourcing 2mA. When the threshold input is above the threshold OUT 3 6 THRES level at the same time the trigger input is above the trigger level, the internal RST 4 5 CONT 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 SAL, PAL, DA PACKAGES than 1V), the output is in the low state. The discarge output has been signifcantly enhanced to eliminate the need for a separate external driver.
