74ALVC245MTC

74ALVC245MTC is a high performance and low voltage 3-state transceiver, belonging to the family of A-series logic Buffers, Drivers, Receivers, Transceivers (LVTTL). It features high speed operation, with a typical 3.2ns delay time, and provides data transmission between two separate buses in both directions. This is done so by using a "Tri-state" output, which means that the output of the buffer can be driven to a High Digital Logic (1) or a Low Digital Logic (0), or is effectively switched off, staying latched (Hi-Z). This makes it possible for more than one device to access the same communication data line at the same time.

The 74ALVC245MTC has two separate 8-bit input and output ports, the 8 pins each port is usually denominated with letters D to H. A further two selection pins are included, the select pins being Serial Data Direction (SDA) and Serial Clock Direction (SCL). When SDA signal is HIGH, then the data from the A-port is transmitted to the B-port, and when SDA signal is low, then the data from the B-port is transmitted to A-port.

The input buffer can support both TTL and CMOS logic levels, and when voltage levels of 2.0V or higher appear at its input, the output is directly driven to 3.3V, making the \'245MTC well-suited for today\'s slightly higher than normal logic levels. It consumes quite low power, only 0.15 mA at 3.3V, making it ideal for portable applications. When the input voltage goes below 0.8V, then the transceiver goes into high impedance and keeps the output buffered, so as to protect any device connected to the output port from possible damage.

The 74ALVC245MTC utilizes Schmitt trigger for noise filtering and for hysteresis improvement. This effect eliminates the bouncing of an input signal when transferring from a high to a low logic level. Diode protection is also provided in the inputs and outputs, so as to protect the device from possible damage due to external, electrostatic voltages.

The 74ALVC245MTC is used in many industrial and consumer electronics applications, such as in GSM cellular phones, for data transmission between two separate peripherals, and in video science projects. It can also be used in data multiplexing application and is ESD-protected in order to increase its robustness.

The 74ALVC245MTC is a versatile, low-power transceiver, suitable for applications where a fast, low voltage, bi-directional data transmission is required. Its unique features include selectable data direction, which makes it easy to switch between transmitting and receiving data, while also offering excellent noise filtering capabilities, as well as diode protection against electrostatic discharge.
