Overview
The 74LVC162244ADGG:11, produced by Nexperia, is a high-performance 16-bit buffer/line driver. This device is designed with 30 Ω series termination resistors and features 3-state outputs, making it versatile for various applications. It can be configured as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. The device includes four output enables (1OE, 2OE, 3OE, and 4OE), each controlling four of the 3-state outputs. This allows for flexible control over the output states, with a HIGH on nOE causing the outputs to assume a high-impedance OFF-state. The 74LVC162244ADGG:11 is also capable of operating in mixed 3.3 V and 5 V environments, thanks to its 5 V tolerant input/output feature.
