74LVC4245A General Description
The 74LVC4245A is a high-performance, low-power, low-voltage, Si-gate CMOS device, superior to most advanced CMOS compatible TTL families.
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 and 5 V bus in a mixed 3/5 V supply environment.
The 74LVC4245A features an output enable (OE) input for easy cascading and a send/receive (DIR) input for direction control. (OE) controls the outputs so that the buses are effectively isolated.
In suspend mode, when VCCA is 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 (typ. 0.7 V). VCCA ³ VCCB (except in suspend mode).
