TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic  
TC74VCX164245FT  
16-Bit Dual Supply Bus Transceiver  
The TC74VCX164245FT is a dual supply, advanced high-speed  
CMOS 16-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 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.  
Weight: 0.25 g (typ.)  
All inputs are equipped with protection circuits against static discharge or transient excess voltage.  
Features (Note)  
Bidirectional interface between 3.3 V and 2.5 V, 3.3 V and 1.8 V, 2.5 V and 1.8 V  
High-speed: t = 4.6 ns (max) (V = 3.3 ± 0.3 V, V = 2.5 ± 0.2 V)

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.
