Applications Mixed Mode Dual Supply Interface Solution
LVX4245 is designed to solve 3V5V interfacing issues
when CMOS devices cannot tolerate IO levels above their
applied VCC If an IO pin of 3V ICs is driven by 5V ICs the
P-Channel transistor in 3V ICs will conduct causing current
flow from IO bus to the 3V power supply The resulting high
current flow can cause destruction of 3V ICs through latch-
up effects To prevent this problem a current limiting resis-
tor is used typically under direct connection of 3V ICs and
5V ICs but it causes speed degradation
In a better solution the LVX4245 configures two different
output levels to handle the dual supply interface issues The
‘‘A’’ port is a dedicated 5V port to interface 5V ICs The ‘‘B’’
port is a dedicated port to interface 3V ICs
Figure 1 shows
how LVX4245 fits into a system with 3V subsystem and 5V
subsystem
This device is also configured as an 8-bit 245 transceiver
giving the designer TRI-STATE capabilities and the ability to
select either bidirectional or unidirectional modes Since the
center 20 pins are also pin compatible to 74 series 245 as
shown in
Figure 2 the designer could use this device in
either a 3V system or a 5V system without any further work
to re-layout the board
