NCA8T245 8-Bit Dual-Supply Bus Transceiver With
Configurable Voltage Translation and 3-State Outputs
Datasheet (EN) 1.1
NCA8T245 is an 8-bit buffer/driver with two separate power supply. The two power supply voltages range from 1.65V to 5.5V. The A port tracks VCCA and B port tracks VCCB, so it supports low-voltage bidirectional shift between any of the 1.8V, 2.5V, 3.3V and 5.5V. NCA8T245 is mainly used for asynchronous communication between two data buses. The device provides a directioncontrol (DIR) input for transmitting data bidirectionally. When DIR is logic high, it transmits data from A to B, and from B to A when DIR is logic low. The output-enable /OE tracks VCCA and is low active, When /OE is high, the outputs are in high-impedance state.
