DESCRIPTION
The AIC1532 is a 32 bit serial to parallel converter IC with 32 high voltage push-pull outputs and TTL com-
patible input signals.The outputs are designed can drive capacitive and resistive loads. An internal protection
function monitors the logic supply voltage (VDD) and disables all output transistors of the high voltage push-
pull outputs if an undervoltage condition is detected.
The IC contains a 32 bit shift register with a clock (CLK) and a data (DATA) input. The data output (OUT)
allows cascading of several ICs. The 32 bit data will be latched with the Latch Enable Signal (LE) in a 32 bit
latch. Three dedicated logic input signals (HI, LO, Z) allow setting of all high voltage outputs instantaneously
to high, low, or high-impedance without changing the setting of the 32 bit shift register and latch.

Page 11: Over-Current Detection
1 nF OVER-CURRENT DETECTION AIC1532 includes an over-current detection circuit of the voltage supply of the high voltage push-pull out- puts. The signal of the over-current detection can delayed or noise filtered by an external R-C combination. AIC1532 provides an over-current measuring output (OCM) and an over-current input (OCI) signal. By activa- tion of the over-current input (OCI) a flip-flop will be set, switching the high voltage push-pull outputs to the low state. - Page 12 (DGND). AIC1532 includes an interval power supply for the high voltage push-pull driver, requiring an external sta- bilization capacitor connected to pin (VD). To ensure reliable operation, pin (VD) must not be connected to any external loads.
