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.
Weight: 0.03 g (typ.)
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.
