74AVC8T245DGVRE4 is an 18/24-bit bidirectional translator, which is designed for asynchronous signaling rates up to 153.6 kbps and synchronization rates up to 622.08 Mbps in LVDS applications. It is part of a family of low voltage differential signaling (LVDS) products and Trans-Lators. It is commonly used in a variety of applications.

The 74AVC8T245DGVRE4 falls into the category of logic translators, level shifters, which are devices that allow communication between two logic families within the same device. It supports two logic families: LVDS and AVCC. The device is non-inverting and translates LVDS input signals to AVCC output levels and AVCC inputs signals to LVDS output levels. It also provides four control input pins for input signal control such as host selection, output enable, and tristate control.

The 74AVC8T245DGVRE4 can be used in a variety of applications, such as:

• Ethernet and LVDS switches
• Industrial and military applications providing galvanic isolation between the two systems
• PCI Express bridges
• Mixed-signal systems interfacing between LVDS and AVCC signaling

The 74AVC8T245DGVRE4 has many features that make it desirable for applications such as low power consumption, low latency, low standby current, and hot insertion capability.

The 74AVC8T245DGVRE4 can operate from a single 3.3V power supply and dissipates very little power. The device can connect two logic families with an operating voltage range of 1.71V to 4.25V for the LVDS side. It supports LVDS, clock and data and DDC input/output signals with a data-rate of up to 153.6 Mbps. The device has a enable pin and a tristate pin to enable/disable the LVDS outputs and can connect to any voltage level.

The 74AVC8T245DGVRE4 offers low power consumption compared to other similar devices and features a maximum of 10.6 mA current consumption at full speed. The device is also hot insertion capable, allowing it to be plugged in to an active system without causing disruption. It has a LVTTL-compatible hold time of 25ns and a corresponding tSK(o)D of 25ns. This feature allows use in extremely high-speed applications.

The working principle of the 74AVC8T245DGVRE4 is straightforward. It provides data-level translations between the two logic families: LVDS and AVCC. The device provides a low-power solution for data-level translation where the input and output levels remain unchanged. The device is also hot insertion capable, allowing for it to be plug-in to active circuits without disruption. The device has a maximum data-rate of 153.6 Mbps and can be used in Ethernet, LVDS switches, and industrial and military applications requiring galvanic isolation.
