The SY100E457JC-TR is a high-speed octal bus transceiver, part of the E Series of signal switches, multiplexers, and decoders. It is a fully-integrated device that uses a 25-bit serial-in/parallel-out (SIPO) shift register and octal 3-state bus transceivers to provide a reliable interface between a microprocessor and main memory.

The SY100E457JC-TR provides an ideal interface for high-speed systems requiring simultaneous transfers of data from multiple data sources. It can be used in applications such as memory buffers, network infrastructure, and high-speed input/output peripherals. The SY100E457JC-TR supports data transmission speeds of up to 30 Mbps, and is available in a 20-pin dual-in-line package

The SY100E457JC-TR operates using a 3-state clocked-sequential logic arrangement. The high-impedance input pins, I/O[7:0], are connected to the data bus, and the output pins, O/I[7:0], are connected to the address bus. The data-in register and the data-out register are both clocked simultaneously. When the data-in pin is asserted, the corresponding bit of the data-in register is clocked into the register, and when the data-out pin is asserted, the corresponding bit of the data-out register can be clocked out. The device\'s clock input, CK, is used to clock the data-in transfer and the data-out transfer separately.

The SY100E457JC-TR features two modes of operation. In 1-of-N mode, the device can transfer data from a single source to multiple destinations, while in N-of-N mode, the device can transfer data between multiple sources and multiple destinations. This versatility allows the SY100E457JC-TR to be used in a wide variety of applications.

In addition to its high-speed operation, the SY100E457JC-TR also features control inputs that can be used to control the operation of the device. The chip enable input, CE, controls the output enable pins, OE, and the chip enable output, /CE, is used to control the input levels of the I/O pins. These features allow the SY100E457JC-TR to be used in applications requiring specific control functions, such as memory buffers, input/output peripherals, and data buses.

The SY100E457JC-TR is a versatile and high-performance solution for many different types of applications, including memory buffers, network infrastructure, and input/output peripherals. With its high-speed operation, versatile modes of operation, and control input capability, the SY100E457JC-TR is a reliable solution for many types of data-handling needs.
