Overview
SAA1029 UNIVERSAL INDUSTRIAL LOGIC AND INTERFACE CIRCUIT GENERAL DESCRIPTION The SAA1029 is a universal bipolar logic and interface IC with high noise immunity and operational stability for industrial control applications.
The most fundamental industrial control functions can be accomplished with only one SAA1029 IC.
MAIN ADVANTAGES • • • • • • • • • • Simple realization of the basic industrial control functions ( logic functions, timing functions, memory functions).
High dynamic and static noise immunity.
High operation stability.
Short-circut protection of inputs and outputs to both VEE and VCC.
Wide interruption results in a safe input LOW state.
LOCMOS (CMOS) compatible.
Ideal applicaion for control loop such as emergency push button.
Wide imput range from 0 to 31.
2 V.
Adjustable output voltage range from 0 to 30 V.
Wide supply voltage range from 14 to 31.
2 V.

net/ The IC comprises, (1) Gate 1 : 4-input AND gate with 1 inverted input, (2) Gate 2 : 3-input AND gate with 1 inverted input and ajustable propagation delay, (3) Gate 3 : 2-input AND gate with 1 inverted input.
The SAA1029 can be used as direct interface with LOCMOS (CMOS) ICs for realizing more complex functions.
Therefore, the output signal can be limited to the voltage level of the common output clamping pin Z.
The propagation delay of NAND gate 2 is adjustable from microsecondes to seconds by using an external capacitor at pin 7 (pin C).
This makes it possible to adapt the control frequency limits to the system, so the optimum dynamic noise immunity can be achieved.
All the static and dynamic circuit values ( including the output voltage) are independent of the supply voltage over a wide operating range.
This allows the use of a simple unstabilized power supply.
The output is held to the LOW state automatically during swithching on the power supply, so a special reset pulse can be omitted.
