General description
●The 74LVC4245A is an octal dual supply translating transceiver featuring non-inverting 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 (pinOE) for easy cascading and a send/receive input (pin DIR) for direction control. PinOE controls the outputs so that the buses are effectively isolated.
●In suspend mode, when VCCAis zero, there will be no current flow from one supply to the
●other supply. The A-outputs must be set 3-state and the voltage on the A-bus must be smaller than Vdiode(typical 0.7 V). VCCA≥VCCB, except in suspend mode.
●Features
●5 V tolerant inputs/outputs, for interfacing with 5 V logic
●Wide supply voltage range:
● 3 V port (VCCB): 1.5 V to 3.6 V
● 5 V port (VCCA): 1.5 V to 5.5 V
●CMOS low-power consumption
●Direct interface with TTL levels
●Inputs accept voltages up to 5.5 V
●High-impedance when VCC= 0 V
●Complies with JEDEC standard no. JESD8B/JESD36
