74AC245TTR Description

Short technical summary and product information.

The 74AC245TTR from STMicroelectronics is an advanced high-speed CMOS octal bus transceiver. It is designed for two-way asynchronous communication between data buses, with the direction of data transmission controlled by the DIR input. The enable input (G) can disable the device, effectively isolating the buses.

 

This transceiver features a wide operating voltage range of 2V to 6V and supports output currents of 24mA. It operates across a temperature range of -55°C to 125°C. The device is fabricated using sub-micron silicon gate and double-layer metal wiring technology, offering improved latch-up immunity and ESD protection.

 

The 74AC245TTR is supplied in a 20-TSSOP surface-mount package. Its symmetrical output impedance and balanced propagation delays make it suitable for high-speed applications. All floating bus terminals during HIGH-Z state must be held HIGH or LOW.
