TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic  
TC74LCX164245FT  
16-Bit Dual Supply Bus Transceiver  
The TC74LCX164245FT is a dual supply, advanced high-speed  
CMOS 16-bit dual supply voltage interface bus transceiver  
fabricated with silicon gate CMOS technology.  
Designed for use as an interface between a 5-V bus and a 3.3-V  
or 2.5-V bus in mixed 5-V/3.3-V or 2.5-V supply systems, it achieves  
high-speed operation while maintaining the CMOS low power  
dissipation.  
It is intended for 2 way asynchronous communication between  
data busses. 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. The B-port  
interfaces with the 5-V bus, the A-port with the 3.3-V or 2.5-V bus.  
Weight: 0.25 g (typ.)  
All inputs are equipped with protection circuits against static discharge or transient excess voltage.  
Features (Note)  
Bidirectional interface between 5-V and 3.3-V or 2.5-V buses  
High-speed: t = 5.8 ns (max)

Power-down protection provided on all inputs and outputs  
Allows A port and V to float simultaneously when OE is “H”.

Latch-up performance: 500 mA  
Package: TSSOP  
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 fixed by means of pull-up or pull-down resistors.
