74CBTLV3245-Q100 8-bit bus switch with output enable Rev. 4 7 May 2020 Product data sheet 1. General description The 74CBTLV3245-Q100 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 OFF OFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down. This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications. 2. Features and benefits Automotive product qualification in accordance with AEC-Q100 (Grade 1) Specified from -40 C to +85 C and from -40 C to +125 C 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: MIL-STD-883, method 3015 exceeds 2000 V HBM JESD22-A114F exceeds 2000 V MM JESD22-A115-A exceeds 200 V (C = 200 pF, R = 0 ) 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 DHVQFN package with Side-Wettable Flanks enabling Automatic Optical Inspection (AOI) of solder joints 3.
