Product Summary

The TCA965B compares an input voltage to a defined voltage window. The digital outputs show whether the input voltage is below, within or above the TCA965B. The TCA965B 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 within a certain tolerance of the required setpoint value in measurement engineering.

Parametrics

TCA965B absolute maximum ratings: (1) Supply voltage (pin 11) Vs: 30V; (2) Difference in input voltage between pins 6, 7, 8 VI: 15V; (3) Input voltage (pins 6, 7, 8, 9) VI: 30V; (4) Output current (pins 2, 3, 13, 14) IQ: 50mA; (5) Output voltage (pins 2, 3, 13, 14) independent of Vs, VQ: 30V; (6) Junction temperature Tj: 150°C; (7) Storage temperature Tstg: -55 to 125°C.

Features

TCA965B features: (1) Two window settings: Cdirect setting of lower and upper edge voltage (window edges) , Cindirect setting by window center voltage and half window width ; (2) Adjustable hysteresis; (3) Digital outputs with open collectors for currents up to 50mA; (4) Adjustable reference voltage VStab.
