SN74AS645N Description

Short technical summary and product information.

The SN74AS645N from Texas Instruments is an octal bus transceiver designed for asynchronous two-way communication between data buses. It supports data transmission from the A bus to the B bus or vice versa, controlled by the direction-control (DIR) input. The output-enable (OE) input allows for disabling the device, effectively isolating the buses.

 

This transceiver operates within a voltage range of 4.5V to 5.5V and is characterized for operation from 0°C to 70°C. It features 3-state outputs and a non-inverting logic type. The device is housed in a 20-pin Dual In-line Package (DIP) with a through-hole mounting type.

 

Key specifications include 8 bits per element and a single element configuration. The current ratings are 15mA and 64mA. This component is suitable for applications requiring bidirectional data transfer and bus isolation.
