74LVC4245A Octal dual supply translating transceiver; 3-state Rev. 12 -- 12 April 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-impedence OFF-state, effectively isolating the buses. In suspend mode, when either supply is zero, there is no current path between supplies. VCCA VCCB, except in suspend mode. 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 (VCC(B)): 1.5 V to 3.6 V * 5 V bus (VCC(A)): 1.5 V to 5.5 V CMOS low-power consumption TTL interface capability at 3.3 V Overvoltage tolerant control inputs to 5.5 V High-impedance when VCC(A) = 0 V Complies with JEDEC standard no.
