Texas Instruments Logic - Logic - Translators, Level Shifters - SN74LVC2T45YZPR SN74LVC2T45YZPR

The SN74LVC2T45YZPR is a dual-bit dual-supply bus transceiver designed for configurable voltage translation between various logic levels, specifically supporting 1.8V, 2.5V, 3.3V, and 5V. It operates with supply voltages ranging from 1.65V to 5.5V for both the A and B ports, allowing for flexible integration in mixed-voltage environments. The device features a low power consumption of 4 OºA maximum I_CC and can drive outputs with up to ±24 mA at 3.3V. This transceiver supports data rates of up to 420 Mbps for 3.3V to 5V translation, with lower rates for other voltage levels. It includes a V_CC isolation feature that places both ports in a high-impedance state if either V_CC input is grounded, enhancing safety during operation. The SN74LVC2T45YZPR is suitable for asynchronous communication between data buses and is fully specified for partial-power-down applications, preventing backflow current when powered down. It is available in a compact 8-pin package, making it suitable for space-constrained designs.
