The DM74AS245WM is an octal bus transceiver logic signal adapter chip produced by Texas Instruments. It\'s an advanced CMOS device that operates from 5 volts and is ideally suited for mixed 5V and 3.3V operations. This device offers high output current capability and low power dissipation, making it perfect for high-speed peripheral data transfers.

The chip\'s main application field is bus buffer and signal adapter. The application fields include any kind of logic-level devices, such as logic signals and data buffer applications, or any digital system requiring signals to be adapted between two different voltage levels.

The DM74AS245WM works according to the single-ended input/ output transceiver logic signal adapter principle. The chip allows bi-directional, 8-bit data transfers between a 5 volt and a 3.3 volt environment such as Mobile and other Industry Standard Bus nodes. The chip features a buffer for each of the two different voltage logic systems, allowing unidirectional data transfers from one voltage level to the other. It also includes input and output enable (OE) pins, allowing data transfers to be stopped and started. The chip provides outputs that comply with the JEDEC standard for LVCMOS and LVTTL.

The chip features a non-inverting mode which allows for higher current outputs and higher speed applications. It also features a high-performance Schottky diode with a diode-protection circuit, so that data can be passed in either direction without any damage or disturbances to the signals. The DM74AS245WM also offers a low power sleep mode, ensuring that power dissipation and current draw are kept to a minimum when the chip is not in use.

The chip is available in a 14-pin narrow 300 mil DIP (Dual In-line Package). The package offers a high degree of protection from electrical interference and other environmental conditions. The power is provided by the VCC and GND pins, and the logic inputs are provided by the IN and OUT pins. The chip also features an enable pin, which allows the chip to be activated and deactivated depending on the desired application.

In summary, the DM74AS245WM is an advanced and versatile transceiver logic signal adapter chip, that is perfect for enabling bi-directional data transfers between two different voltage levels such as 5 volts and 3.3 volts. The chip is ideal for applications requiring high output current capabilities and low power dissipation. It is available in a 14-pin narrow 300 mil DIP package, which provides a high degree of protection from electrical interference and other environmental conditions.
