Overview
The 74LVC16244ADGG is a 16-bit buffer/line driver produced by NXP USA Inc. (now known as Nexperia). This device is designed to operate in a wide range of supply voltages from 1.2 V to 3.6 V, making it versatile for various applications. It features 3-state outputs and 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, allowing for flexible control over the output states.
The 74LVC16244ADGG is also 5 V input/output tolerant, enabling it to interface with 5 V logic devices, and it supports mixed-mode signal operation. This makes it suitable for use in mixed 3.3 V and 5 V environments. Additionally, the device includes Schmitt-trigger action at all inputs, which enhances its tolerance to slower input rise and fall times.
