SCES516E is a dual-bit noninverting bus transceiver that uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.65 V to 5.5 V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65 V to 5.5 V. This allows for universal low-voltage bidirectional dual-channel communication with data rates up to 420 Mbps.
The SN74LVC2T45 from Texas Instruments is a dual‑bit, dual‑supply bus transceiver that supports bidirectional voltage translation between 1.8 V, 2.5 V, 3.3 V and 5 V nodes. Each port can operate over a 1.65 V to 5.5 V supply range and features partial‑power‑down mode, high‑impedance isolation, and ESD protection.
The datasheet provides detailed electrical and switching characteristics, recommended operating conditions, mechanical package drawings, and ordering information for NanoStar™ and NanoFree™ package options. It also includes the standard TI warranty and important notice about product availability.
| Supply voltage range (VCCA/VCCB) | 1.65 V to 5.5 V |
|---|---|
| Maximum data rate (3.3‑V to 5‑V translation) | 420 Mbps |
