The SN74ACT1284DW is a 7-bit bus interface transceiver manufactured by Texas Instruments. This device is designed for asynchronous two-way communication between data buses, supporting IEEE 1284 electrical specifications. It operates with a supply voltage ranging from 4.5V to 5.5V and offers a maximum data rate of 12 Mbps.
The transceiver features 3-state outputs that can directly drive bus lines. The direction of data transmission for bits 1 through 4 is controlled by the DIR input, while bits 5 through 7 always transmit in the A-to-B direction. The output drive is configurable via the high-drive (HD) control pin, allowing for either totem-pole or open-drain configurations.
Packaged in a 20-SOIC format, the SN74ACT1284DW is suitable for surface mount applications. Its flow-through architecture optimizes PCB layout, and center-pin VCC and GND configurations minimize high-speed switching noise. The device also includes ESD protection exceeding JESD 22 standards.
Key electrical characteristics include a maximum propagation delay of 20 ns at 5V and a maximum supply current of 1.5 mA. The operating temperature range is from 0°C to 70°C.
