Working Principle

The 74ABT646APW,112 is a 16-bit bidirectional logic buffer driver, receiver, transceiver and receiver device designed for low-voltage logic applications. The device features two data flows, both carrying eight bits of data, each having separate data inputs and outputs. Each data flow can be independently enabled and disabled as desired. The device has two modes of operation: repeater mode, in which it acts as a simple bus repeater, and bus driver mode, in which it acts as an extended bus driver, allowing higher fan-outs and data throughput. In either mode, the device will isolate the data flow in the positive, or downstream, direction and repeat it in the negative, or upstream direction.The device provides a data bus with programmable pull-up and pull-down resistors, as well as multiple levels of threshold voltage and hysteresis. The device will also pride off-chip protection diodes and integrated resistors, enabling the device to interface with non-CMOS components.
