SN74ALVTHR16245LR TI Bus Transceiver | 48-SSOP | 2.3V-3.6V, 32mA

Product Overview

The SN74ALVTHR16245LR is a 16-bit bus transceiver from Texas Instruments, designed for asynchronous bidirectional communication between data buses. It operates with a supply voltage range of 2.3V to 3.6V, making it suitable for low-voltage applications. The device features dual supply pins (VCCA and VCCB) for voltage-level translation, allowing seamless interfacing between different voltage domains. Housed in a 48-pin SSOP package, it provides high drive capability of ±32mA at the A port and ±12mA at the B port. The SN74ALVTHR16245LR is part of the ALVTH family, offering advanced low-voltage CMOS technology with high speed and low power consumption.
