SN74LV161284,pdf(19-BIT BUS IN

The SN74LV161284 is designed for 4.5-V to 5.5-V V_CC operation. This device provides asynchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements.

This device has eight bidirectional bits; data can flow in the A-to-B direction when DIR is high, and in the B-to-A direction when DIR is low. This device also has five drivers, which drive the cable side, and four receivers. The SN74LV161284 has one receiver dedicated to the HOST LOGIC line and a driver to drive the PERI LOGIC line.

The output drive mode is determined by the high-drive (HD) control pin. When HD is high, the B, Y, and PERI LOGIC OUT outputs are in a totem-pole configuration, and in an open-drain configuration when HD is low.
