74AVC1T45W6-7

The 74AVC1T45W6-7 from Diodes Incorporated is a single-bit, dual-supply translating transceiver designed for transmitting logic bits across different voltage domains. It features a wide supply voltage range from 1.2V to 3.6V for both VCCA and VCCB, enabling universal low-voltage translation.

The transceiver's direction is controlled by the DIR pin. When DIR is high, pin A is an input and pin B is an output. Conversely, when DIR is low, the roles are reversed. The tri-state output feature is active when either power supply voltage is zero, providing power-down electrical isolation.

This device operates within a temperature range of -40°C to 85°C and is available in a compact SOT-23-6 (SOT-26) surface-mount package. Key electrical characteristics include an output drive of ±12mA at 3.3V and low quiescent current. ESD protection exceeds JESD 22 standards, and it supports partial-power-down operation via its IOFF feature.

Applications for the 74AVC1T45W6-7 include voltage level translation in systems with different logic voltage requirements and power-down signal isolation. It is well-suited for use in mobile devices, PCs, networking equipment, and consumer electronics.
