SN74ALS638AN Description

Short technical summary and product information.

The SN74ALS638AN is an octal (8-bit) bus transceiver from Texas Instruments featuring inverting outputs. It operates from a 4.5V to 5.5V supply voltage and is designed for bidirectional asynchronous communication between two data buses. The device offers both open-collector and push-pull output configurations, with output current capabilities of 24mA and 15mA.

 

This transceiver is part of the Advanced Low-Power Schottky (ALS) logic family, providing a balance of speed and power efficiency. It is suitable for bus-oriented systems where inverting signal transmission is required. The device includes a single enable input for direction control.

 

The SN74ALS638AN is housed in a 20-pin DIP (0.300", 7.62mm) package with through-hole mounting, making it compatible with traditional PCB assembly processes. The operating temperature range is 0°C to 70°C, suitable for commercial applications.
