3 Description
The SN74LVC8T245-Q1 is an eight bit non-inverting bus transceiver with configurable dual power supply rails that enables bidirectional voltage level translation. The SN74LVC8T245-Q1 is optimized to operate with VCCA and VCCB set at 1.65 V to 5.5 V. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.65 V to 5.5 V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65 V to 5.5 V. This allows for universal low-voltage bidirectional translation between any of the 1.8-V, 2.5-V, 3.3-V, and 5.5-V voltage nodes.
The SN74LVC8T245-Q1 is designed for asynchronous communication between two data buses. The logic levels ...
