The SN74ACT245PW is an octal bus transceiver and bidirectional logic-level translator that is capable of transferring data between two buses that use different logical levels. It can handle both 3.3V and 5V systems to permit direct connections between systems with different power supplies.

Application Field

The SN74ACT245PW can be used in nearly any high speed logic application. It can help to prevent loading of the bus data lines when many devices are connected together and ensures a high performance data transfer rate between two drastically different logic levels. The SN74ACT245PW is an integral part of many circuits because of its capability to interface both 3.3V and 5V systems.

The SN74ACT245PW is often used in applications such as test systems, medical instruments, industrial controllers, communication equipment, automotive applications, and network systems that require a logic-level translator.

Working Principle

The SN74ACT245PW converts between two logic levels of different families using TTL, Schottky, and CMOS logic. It is capable of driving up to 24mA per output as well as receiving up to 30mA per input. The SN74ACT245PW receives data from the A-bus, translates the data to the B-bus, and outputs the translated data on the other side.

The SN74ACT245PW is designed for operation from either a 5V or 3V power supply. It features an active on-chip ESD protection and latch-up protection. The device also has input hysteresis to reduce noise susceptibility and to increase the noise-immunity of the device.

The SN74ACT245PW can transfer data at speeds of up to 13MHz. It has four inhibit control inputs that can be used to disable the A and B data paths independently of each other. The device has a low power consumption of approximately 5 mA and a power-down feature that reduces its power consumption even further.
