74CBTLV3245 8-bit bus switch with output enable Rev. 3 11 November 2016 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 I . The I circuitry disables the output, preventing the damaging OFF OFF backflow current through the device when it is powered down. 2. Features and benefits Supply voltage range from 2.3 V to 3.6 V High noise immunity Complies with JEDEC standard: JESD8-5 (2.3 V to 2.7 V) JESD8-B/JESD36 (2.7 V to 3.6 V) ESD protection: HBM JESD22-A114F exceeds 2000 V MM JESD22-A115-A exceeds 200 V CDM AEC-Q100-011 revision B exceeds 1000 V 5 switch connection between two ports Rail to rail switching on data I/O ports CMOS low power consumption Latch-up performance exceeds 250 mA per JESD78B Class I level A I circuitry provides partial Power-down mode operation OFF Multiple package options Specified from 40 Cto+85 C and 40 Cto+125 C74CBTLV3245 Nexperia 8-bit bus switch with output enable 3.
