74LVC4245A Octal dual supply translating transceiver; 3-state Rev. 10 — 18 December 2012 Product data sheet 1. 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 3Vand5V supply environment. The device features an output enable input (pin OE) for easy cascading and a send/receive input (pin DIR) for direction control. Pin OE controls the outputs so that the buses are effectively isolated. In suspend mode, when V is zero, there will be no current flow from one supply to the CC(A) other supply. The A-outputs must be set 3-state and the voltage on the A-bus must be smaller than V (typical 0.7 V). diode V  V , except in suspend mode. CC(A) CC(B) 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 Vto3.6V CC(B) 5 V bus (V ): 1.5 Vto5.5V CC(A)  CMOS low-power consumption  Direct interface with TTL levels  Inputs accept voltages up to 5.5 V  High-impedance when V = 0 V CC(A)  Complies with JEDEC standard no. JESD8B/JESD36  ESD protection: HBM JESD22-A114F exceeds 2000V MM JESD22-A115-A exceeds 200V  Multiple package options  Specified from 40C to +85C and 40C to +125C
