Overview
74CBTLV3245 8-bit bus switch with output enable Rev.
5 — 7 May 2020 Product data sheet 1.
General description The 74CBTLV3245 is an 8-pole, single-throw bus switch.
The device features a single output enable input (OE) that controls eight switch channels.
The switches are disabled when OE is HIGH.
Schmitt-trigger action at control inputs makes the circuit tolerant of slower input rise and fall times.
This device is fully specified for partial power-down applications using IOFF.
The IOFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down.
