SN74LVC2T45DCUT TI Dual-Bit Voltage-Level Translator | 8-VSSOP | 1.65V-5.5V

Product Overview

The SN74LVC2T45DCUT from Texas Instruments is a dual-bit, non-inverting voltage-level translator designed for bidirectional voltage translation between two independent power-supply rails. It operates over a wide voltage range from 1.65V to 5.5V on both VCCA and VCCB, making it suitable for multi-voltage systems. The device features a direction control pin (DIR) that determines the data flow direction, enabling seamless communication between different voltage domains. Housed in a compact 8-VSSOP package, it is ideal for space-constrained applications.

Detailed Technical Specifications

Key Features

• Bidirectional voltage translation with direction control (DIR)
• Wide supply voltage range: 1.65V to 5.5V on both ports
• High data rate: up to 420 Mbps at 5V
• Low propagation delay: typical 3.5 ns at 3.3V
• High output drive: ±24 mA at 3.3V
• Power-off protection: Ioff circuitry disables outputs when VCC=0V
• ESD protection exceeds JESD 22 (2000V HBM, 1000V CDM)
• Small 8-VSSOP package saves board space
