74CBTLV3244 8-bit bus switch with 4-bit output enables Rev. 3 8 November 2016 Product data sheet 1. General description The 74CBTLV3244 is a dual 4-pole, single-throw bus switch. The device features two output enable inputs (nOE) that each control four switch channels. The switches are disabled when the associated nOE input 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, OFF OFF preventing the damaging 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 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 C74CBTLV3244 Nexperia 8-bit bus switch with 4-bit output enables 3.
