A SN74AVC32T245GKER belongs to the logic - translators, level shifters category. This particular device is an Integrated Circuit (IC) that takes parallel electrical signals from one source and translates them into a different set of parallel electrical signals on the output while also having the capability to level-shift between different reference and logic voltages.

The SN74AVC32T245GKER is a high-performance, low-power, low-voltage, and configurable 32-bit translator with integrated 3-state capability, which operates from a single 1.8V to 3.3V VCC supply and features two independent and configurable voltage supply and logic reference voltage sources to support an extended range of reference and logic voltages. Specifically, this device also supports 3-state signals to enable interfacing with open-drain and 1-to-1 analog switch matrix systems.

The SN74AVC32T245GKER is part of a family of devices that has the same function but varies by bus or port width (32 parallel I/O, 8 parallel I/O, 8 serial I/O and 4 parallel I/O).

The SN74AVC32T245GKER, like other logic translators, level shifters, is used to translate, interface and level shift digital signals between different voltage levels and standards, such as TTL, LVCMOS, PCI Express and more. It is available in a space-saving small-footprint 8-pin VSSOP package, and is widely used in applications such as data communications, industrial Ethernet, software where low power, speed and flexibility are required.

The SN74AVC32T245GKER has a working principal that is as follows. Internally, the differential receiver receivers the input signals (VCC1, VCC2) and compares the two inputs for equivalence or for mismatching. If the two signals are equal, the bit translation can be enabled. If there is a difference between the two input signals, the SN74AVC32T245GKER will pull the translated single output of the differential receiver low, thus disabling the bit translation.

The SN74AVC32T245GKER also provides output levels shifting which is activated by a switch. This switch negates the “VCC1” pad which then allows the VCC2 voltage to set the ‘logic threshold’ voltage level on the output side of the translator (VCCO). This allows the device to shift from one logic voltage level to another.

The SN74AVC32T245GKER is a great device for applications requiring a high degree of speed and flexibility in signal translation processes for two different voltage levels. It is capable of level shifting signals from one level to another, making it ideal for applications such as PCI Express, Ethernet and many more.
