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 3 V and 5 V 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 VCC(A) 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 (typical 0.7 V).  
VCC(A) VCC(B), except in suspend mode.  
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  
Direct interface with TTL levels  
Inputs accept voltages up to 5.5 V  
High-impedance when VCC(A) = 0 V  
Complies with JEDEC standard no. JESD8B/JESD36  
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
