description
This 8-bit (octal) noninverting bus transceiver
uses two separate power-supply rails. The A port,
V
CCA
, is dedicated to accept a 5-V supply level,
and the configurable B port, which is designed to
track V
CCB
,
accepts voltages from 3 V to 5 V. This
allows for translation from a 3.3-V to a 5-V
environment and vice versa.
The SN74LVCC4245A is designed for asynchronous communication between data buses. The device
transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the
direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so the buses are
effectively isolated.
The SN74LVCC4245A is characterized for operation from –40
°
C to 85
°
C.
