74AVC8T245数据手册集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF

描述 Description

The 74AVC8T245 is an 8-bit, dual-supply bus transceiver with configurable voltage translation. The An and Bn are 8-bit input-output ports, DIR is the direction control input. OE is an output enable input and VCCA and VCCB are dual supply pins. The supply voltage pins accept any voltage from 0.8V and 3.6V. This makes the device suitable for low voltage bidirectional translation voltage nodes of 0.8V, 1.2V, 1.5V, 1.8V, 2.5V and 3.3V. An, OE and DIR pins are referenced to VCCA and Bn pins are referenced to VCCB.
The direction control (DIR) input determines the direction of the data flow. The DIR (active-high) enables data from An ports to Bn ports. The DIR (active-low) enables data from Bn ports to An ports. The output enable (OE) input, when high, disables both An and Bn ports, so the buses are effectively isolated.
