SN74LVTH18646APM TI Bus Transceiver | 64-LQFP (10x10) | 3.3V, 18-Bit

Product Overview

The SN74LVTH18646APM is a high-performance 18-bit bus transceiver from Texas Instruments, designed for 3.3-V systems with 5-V tolerant I/Os. It features dual-supply voltage operation (VCC = 2.7 V to 3.6 V) and supports bidirectional data flow between two buses (A and B). The device is housed in a compact 64-pin LQFP (10x10 mm) package, making it ideal for space-constrained applications. It offers bus-hold circuitry on all data inputs, eliminating the need for external pull-up resistors and reducing power consumption.

Detailed Technical Specifications

Key Features
