LSI Computer Systems, Inc. Specialized ICs LS7082N1-S

The LS7082N1-S is a CMOS quadrature clock converter designed for applications involving optical or magnetic encoders. It supports mode selection for x1, x2, and x4 operation, with an output clock frequency of up to 16MHz. The device features an INDEX input and output for absolute position reference pulses, as well as UP/DOWN indicator outputs for direction sensing. This IC operates within a supply voltage range of +3V to +12V and is compatible with both TTL and CMOS logic levels. It includes on-chip filtering for inputs, ensuring reliable performance in noisy environments. The programmable output clock pulse width can be adjusted using an external resistor connected to the RBIAS pin. The LS7082N1-S is suitable for interfacing with standard Up/Down counters, making it a versatile choice for projects requiring precise position and direction sensing. Its operating temperature range is -20¬8C to +85¬8C, with a maximum supply voltage of 16V.
