TC74VCX164245FT
16-Bit Dual Supply Bus Transceiver
The TC74VCX164245FT is a dual supply, advanced high-speed
CMOS 16-bit 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 3.3-V or 2.5-V bus
and a 2.5-V or 1.8-V bus in mixed 3.3-V or 2.5-V/2.5-V or 1.8-V
supply systems.
The B-port interfaces with the 3.3-V or 2.5-V bus, the A-port with
the 2.5-V or 1.8-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.

• 3.6-V tolerant function and power-down protection provided on all inputs and outputs
Note: Do not apply a signal to any bus pins when it is in the output mode. Damage may result.
All floating (high impedance) bus pins must have their input level fixed by means of pull-up or pull-down
resistors.
