72V70800TFG

Introduction

The 72V70800TFG is a logic and signal switchable multiplexer and decoder from Texas Instruments. It is designed to operate in the 1.8V to 5.5V voltage range and can operate over a wide temperature range of -40°C to 85°C. The 72V70800TFG is available in a 24-pin TSSOP package and is based on a 15-bit binary tree architecture that provides high decode rates, bandwidth and low gate count.

Application Field

The 72V70800TFG has sound uses in various applications. It is primarily used to decode serial communication commands and translates it to an easy to read binary format which can then be interpreted. It is also used to switch logic signals in a digital system. The 72V70800TFG is suitable for applications such as memory mapping, system clock distribution and data packet routing.

Working Principle

The 72V70800TFG features a 15-bit architecture which can decode 64Mb/sec signals. Each 15-bit transistor switch is connected to one of the 15 parallel logic inputs. When the logic input is present, the corresponding transistor switch is turned on, connecting the logic input to its associated multiplexer output.

The other inputs of the 72V70800TFG are a single enable input, an asynchronous clear and a decoded address bus. The enable input controls the transistor switches and when enabled, it allows the chip to process the address bus.

The address bus provides the multiplexer with the location of the data to be outputted. The logic inputs of the chip are scanned and the first logic input to receive a valid address is outputted by the multiplexer to the associated output. The output of the 72V70800TFG can be connected to another device to continue the operation of the system.

Conclusion

The 72V70800TFG is a logic switchable multiplexer and decoder from Texas Instruments. It is based on a 15-bit architecture that allows it to process 64Mb/sec signals. It is mainly used for decoding serial communication commands and can also be used for logic switching of signals. With its wide temperature range, it is suitable for various applications including memory mapping, system clock distribution, and data packet routing.
