SN74ACT1284DBR Description

Short technical summary and product information.

The SN74ACT1284DBR from Texas Instruments is a 7-bit bus interface transceiver with 3-state outputs, specifically designed to meet IEEE 1284 electrical specifications.

 

This device supports asynchronous two-way communication between data buses. It operates within a supply voltage range of 4.5V to 5.5V, with inputs capable of accepting voltages up to 5.5V. The transceiver features 3-state outputs that can directly drive bus lines. Its flow-through architecture is optimized for PCB layout, and center-pin VCC and GND configurations help minimize high-speed switching noise.

 

The SN74ACT1284DBR is housed in a 20-SSOP package, suitable for surface mounting. It operates within a temperature range of 0°C to 70°C. The device also includes ESD protection exceeding JESD 22 standards.

 

This transceiver is ideal for applications requiring parallel peripheral interface communication, such as printer interfaces and other data transfer systems adhering to IEEE 1284 standards.
