Working Principles

The SN74LVC652ADWR utilizes low-voltage CMOS technology to perform bidirectional voltage translation. It automatically detects the direction of data flow and adjusts the level translation accordingly. The device operates within a wide supply voltage range, allowing it to interface with different voltage domains commonly found in modern electronic systems.

When a logic signal is applied to the input pins, the SN74LVC652ADWR translates the voltage level to match the target voltage domain. The translated signal is then available at the corresponding output pins. The tri-state outputs enable multiple devices to share a common bus by allowing them to disconnect from the bus when not actively transmitting data.
