SN74AXCH1T45DRY2

The SN74AXCH1T45DRY2 from Texas Instruments is a single-bit, non-inverting bus transceiver designed for dual-supply applications. It features individually configurable power-supply rails, allowing each port to operate with a power supply range from 0.65 V to 3.6 V. This device is suitable for voltage translation tasks, supporting data rates up to 500 Mbps when translating from 1.8 V to 3.3 V.

Key features include bus-hold on data inputs, which eliminates the need for external pull-up or pull-down resistors, and a glitch-free power supply sequencing capability. The transceiver also incorporates an isolation feature where all I/Os become high-impedance if either VCC input drops below 100 mV, and supports partial-power-down mode operation. Its latch-up performance exceeds 100 mA per JESD 78, Class II, and ESD protection exceeds JESD 22 standards.

Packaged in a 6-SON (1.45x1) or 6-UFDFN format, the SN74AXCH1T45DRY2 is designed for surface mount applications. It operates within a temperature range of -40°C to 125°C (TA). The device offers bidirectional channel type and tri-state, non-inverted output type, making it versatile for various interface and logic translation needs.
