TCA965 Window Discriminator DIP14 Original and similar items

The TCA965 (or TCA965B) is a bipolar window discriminator integrated circuit (IC), originally manufactured by Siemens Semiconductor Group (now part of Infineon Technologies). Key Features The TCA965 compares an input voltage to a defined voltage window, with digital outputs indicating if the voltage is below, within, or above this range. The window can be set by defining the lower and upper voltage edges or by using a center voltage and half window width. The IC includes adjustable hysteresis for its internal comparators, open-collector digital outputs capable of handling up to 50 mA, and operates on a supply voltage range of 4.5 V to 30 V. It can achieve switching frequencies up to 50 kHz as a Schmitt trigger and has Inhibit A and B inputs to control the outputs. Applications The TCA965 is suitable for applications such as tracking or compensating controllers in control engineering, selecting DC voltages within a tolerance in measurement engineering, power supply monitoring and over-voltage protection, and potentially hot-swap voltage control. Package It is available in packages including P-DIP-14 and P-DSO-14-1 (SMD). In summary, it is a versatile component for applications requiring precise monitoring of voltage within specific limits.
