Logic translators and level shifters are essential to connect devices from different logic families which run on different power supplies. 74LVC8T245BQ,118 is one of them. It is an octal bidirectional transceiver with push-pull output and 5.2V tolerant inputs.

This translates low voltage (LVTTL) to high voltage (LVHSTL) and vice versa. Signal levels beyond the supply voltage can be transfer to the other side without the need of an external power supply.

It integrates an 8-bit buffers with three-state outputs on one side and an 8-bit transceivers with active low output enable and receiver input-enable control on the other side. Outputs can be directly connected to 5V systems.

It applies to applications in a variety of logic voltage domains, e.g. 2.5V, 3.3V, 5V level signals in power supplies application such as low voltage load switch, open-drain output buffer, bipolar input buffer, and latency matching.

74LVC8T245BQ,118 features include low power dissipation, high noise immunity, baterry backup capability, bus hold on high-impedance inputs, 3.3V compatible logic, and multiple supply voltage support.

It operates on a wide range of supply voltage between 0~7V and its high-impedance input and output enable allows signals to float without pulling current when not in use. When pins are disabled, the chips do not consume power which makes it ideal for low power applications.

It is also be used in PC interfaces and telecommunications, system clocks and terminators, integrated circuit tester and troubleshooting, LED lighting system, control panelized systems, and industrial control.

It also works with low voltage logic families such as LCMX, LCMX2K and AOI devices. It is configured for a digital data conversion from one logic family to another and a level shifting from one supply voltage to another.

The working principle of the 74LVC8T245BQ,118 lies in transceiver logic where bidirectional data is transmitted over a pair of differential lines. This transceiver always has an active driver on one side and a receiver on the other side. When the enable signal on the receiver is active, the data is read from the receiver and when it is inactive, the input from the receiver is left in its floating state, allowing the signal to be sent from the driver.

The transceiver normally needs to change levels to the opposite logic family when sending data over a long distance, unless the logic family on both sides is the same. This is where the 74LVC8T245BQ,118 transceiver of the LVC logic family can come to the rescue.

The 74LVC8T245BQ,118 helps translates levels from one logic family to another and levels from one voltage domain to another. It supports 5V, 3V and 2.5V logic and hence is the perfect device when it comes to level shifting and logic family conversion.
