74LVC4245A Octal dual supply translating transceiver 3-state Rev. 13 27 August 2021 Product data sheet 1. General description The 74LVC4245A is an octal dual supply translating transceiver featuring 3-state bus compatible outputs in both send and receive directions. It is designed to interface between a 3 V and 5 V bus in a mixed 3 V and 5 V supply environment. The device features an output enable input (OE) and a send/receive input (DIR) for direction control. A HIGH on OE causes the outputs to assume a high-impedance OFF-state, effectively isolating the buses. In suspend mode, when either supply is zero, there is no current path between supplies. V V , except in suspend mode. CCA CCB Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times. 2. Features and benefits 5 V tolerant inputs/outputs, for interfacing with 5 V logic Wide supply voltage range: 3 V bus (V ): 1.5 V to 3.6 V CC(B) 5 V bus (V ): 1.5 V to 5.5 V CC(A) CMOS low-power consumption TTL interface capability at 3.3 V Overvoltage tolerant control inputs to 5.5 V High-impedance when V = 0 V CC(A) Complies with JEDEC standard no. JESD8B/JESD36 Latch-up performance meets requirements of JESD78 Class 1 ESD protection: HBM JESD22-A114F exceeds 2000 V MM JESD22-A115-A exceeds 200 V Multiple package options Specified from -40 C to +85 C and -40 C to +125 C 3.
