2 Dual Supply Bus Transceiver
The TC7MPN3245FTG is an advanced high-speed CMOS 8-bit
dual supply voltage interface bus transceiver, fabricated with silicon
gate CMOS technology.
It is also designed with over-voltage tolerant inputs and outputs up
to 3.6 V.
Designed for use as an interface between a 1.2-V, 1.5-V, 1.8-V, or
2.5-V bus and a 1.8-V, 2.5-V or 3.6-V bus in mixed 1.2-V, 1.5-V,
1.8-V or 2.5-V/1.8-V, 2.5-V or 3.6-V supply systems.
The A-port interfaces with the 1.2-V, 1.5-V, 1.8-V or 2.5-V bus, the
B-port with the 1.8-V, 2.5-V, 3.3-V bus.
The direction of data transmission is determined by the level of the
DIR input. The enable input (
OE
) can be used to disable the device
so that the buses are effectively isolated.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.
Features
Bidirectional interface between 1.2-V and 1.8-V, 1.2-V and 2.5-V, 1.2-V and 3.3-V, 1.5-V and 2.5-V, 1.5-V and 3.3-V,
1.8-V and 2.5-V, 1.8-V and 3.3-V or 2.5-V and 3.3-V buses.

Suitable for battery-driven applications such as PDAs and cellular phones.
Floating A-bus and B-bus are permitted. (when
OE
=
“H”)
3.6-V tolerant function and power-down protection provided on all inputs and outputs.
Note 1: Do not apply a signal to any bus pin when it is in the output mode. Damage may result.
Note 2: RA or RMA flux is recommended when mounting the VQON package.
