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 SAA1029IC. Figure 1 shows the lo gic
configuration.
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 adjustable 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 claming pin Z.
The propagation delay of NAND gate 2 is adjustable from microseconds by using an external
capacitor at 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.
Features
• 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 V
EE
and V
CC.
• Wide interruption results in a safe input LOW state.
• LOCMOS (CMOS) compatible.
