Overview
The 74CBTLV3245BQ-Q100115, produced by Nexperia USA Inc., is an 8-pole, single-throw bus switch. This device is designed to manage data flow in various electronic systems, featuring a single output enable input (OE) that controls eight switch channels. The switches are disabled when the OE input is HIGH, and the device includes Schmitt-trigger action at control inputs to enhance tolerance to slower input rise and fall times. This component is fully specified for partial power-down applications using IOFF circuitry, which prevents damaging backflow current when the device is powered down.
