PRODUCTION DATA - MaY 3, 2011

E910.01

The actual method of establishing that an output is open is by interrogating the state of the data output SO. When

an output OUTx is selected by means of a HIGH level on the SI pin (output OUTx disabled) a LOW level appears on

the SO pin. Thus the open condition of the output is indicated. This function is the inverse of the short circuit con-

dition above.

Over temperature Protection: If the chip temperature exceeds the protection threshold of typically 165°C all out-

put drivers are disabled and the data stored in the latches are retained. When the temperature drops below the

protection threshold of typically 140°C the previously stored condition is restored providing no new data have

been loaded into the shift register by SI during this protection condition otherwise the stored data is overridden.

This is also the case, when a RESET signal is received or when a falling edge on CE causes the shift register to be

read. (see Figure 11)

The actual method of establishing that the device is in thermal protection shut down is by interrogating the state

of the data output SO. When an output OUTx is selected by means of a LOW level on the SI pin (output OUTx ena-

bled) a HIGH level appears on the SO pin for all outputs. Thus the thermal shutdown condition is indicated. It is

highly unlikely that a short circuit condition can occur in all outputs simultaneously.

Test Modes:

If a voltage of greater than 3V and lower than 8V is applied to the TEST input, the device will switch into the Test

Mode 1. In this mode the counter chain following the internal RC oscillator is shortened. The oscillator signal

(divided by 2) appears on the output SO.

Test mode 2: If the voltage at the TEST input is greater than 16V additionally the over temperature protection

circuit is set between +25°C and +85°C.
