SN74LVC16T245ZQLR Description

The SN74LVC16T245ZQLR from Texas Instruments is a high-performance, bidirectional voltage-level translation transceiver designed for mixed-voltage systems. Housed in a compact 56-ball BGA package, this 16-bit (2 x 8-bit) transceiver supports voltage translation between 1.65V and 5.5V, making it ideal for interfacing between low-voltage processors and higher-voltage peripherals. With a robust 32mA output drive capability (both high and low), it ensures reliable signal integrity in noisy environments. The device is ROHS3 compliant and features a surface-mount design, suitable for automated assembly processes. Although marked as obsolete, it remains a viable solution for legacy designs requiring stable, high-speed bidirectional communication.
