Window Discriminator TCA 965 B Preliminary Features q Bipolar IC q q q Two window settings – direct setting of lower and upper edge voltage (window edges) – indirect setting by window center voltage and half window width Adjustable hysteresis Digital outputs with open collectors for currents up to 50 mA Adjustable reference voltage VStab P-DIP-14-1 Type s TCA 965 B s Not for new design Ordering Code Q67000-A8338 Package P-DIP-14-1 The window discriminator compares an input voltage to a defined voltage window. The digital outputs show whether the input voltage is below, within or above this window. The TCA 965 B window discriminator is especially suitable as a tracking or compensating controller with a dead band in control engineering and for the selection of DC voltages withi [ ... ]
