The SN74AVC4T774RSVR, developed by Texas Instruments, is a 4-bit bidirectional voltage-level translator designed for high-speed, low-power signal translation in mixed-voltage digital systems. It enables seamless communication between interfaces operating at different voltage levels (1.2V to 3.6V) and supports independent power supplies (VCCA/VCCB) for flexible system integration. Encased in a compact 16-pin UQFN (2.6x1.8 mm) package, this device is ideal for space-constrained applications requiring robust signal integrity and efficient power management.

Key Features

• Dual-Supply Operation: Supports voltage translation between 1.2V to 3.6V domains, accommodating low-voltage (1.2V–1.5V) and standard (2.5V–3.3V) interfaces.
• High-Speed Performance: Achieves data rates up to 380 Mbps with a propagation delay of 2.4 ns, ensuring efficient high-speed data transfer.
• 4-Channel Bidirectional Control: Four independent channels with configurable direction control (DIR) and output enable (OE) for flexible asynchronous communication.
• Low-Power Efficiency: Operates at minimal supply current (40 µA) and features Ioff partial-power-down mode to reduce standby power consumption.
• Overvoltage Tolerance: Inputs withstand up to 4.6V, ensuring compatibility with legacy systems.
• Enhanced Reliability: Includes ESD protection (±8 kV HBM) and operates across a wide temperature range (-40°C to +85°C).
• RoHS Compliance: Meets environmental standards for global applications.

Application Areas

The SN74AVC4T774RSVR is widely used in:

• Consumer Electronics: Smartphones, tablets, and wearables for interfacing low-voltage processors with peripheral devices.
