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 Vand 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 isolate d .
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 ex ce ed s 200 V
Multiple package options
Specified from 40 C to +85 C and 40 C to +125 C

5.1 Pinning
5.2 Pin description
(1) This is not a supply pin. The substrate is attached to this
pad using conductive die attach material. There is no
electrical or mechanical requirement to solder this pad.
However, if it is soldered, the solder land should remain
floating or be connected to GND.
