PI74LVC4245A
8-Bit Dual Supply Bus Transceiver
with 3-State Outputs

P-0.2 08/11/03
ADVANCE INFORMATION
DC Electrical Characteristics
(Over Supply Voltage and Operating Temperature Ranges, unless otherwise specified)
B-Port (3.3V)
Notes:
5. All typical values are measured at V
CCB
= 3.3V, T
A
= 25°C
6. For I/O ports, the parameter I
OZ
includes the input leakage current.
7. This is the increase in supply current for each input that is at one of the specified voltage levels, rather than 0V or the associated V
CC
.
