The Siemens TCA965B is a window discriminator that compares an input voltage to a defined voltage window, providing digital outputs to indicate if the input is below, within, or above the window. This device is particularly suitable for tracking or compensating controllers with a dead band in control engineering, and for selecting DC voltages within a specific tolerance in measurement engineering.
Key features include two window settings, which can be set directly by defining the lower and upper edge voltages or indirectly by specifying the window center voltage and half window width. It also offers adjustable hysteresis and digital outputs with open collectors capable of handling currents up to 50 mA. The device has an adjustable reference voltage (VStab).
When used as a Schmitt trigger, the TCA965B can achieve switching frequencies up to a typical value of 50 kHz. The component is housed in a PG-DIP-14-1 package and is suitable for through-hole mounting.
The TCA965B is RoHS3 compliant and has an MSL rating of 1. It is noted as 'Not for new design'.
