TC74VHCV245FT/FK  
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic  
TC74VHCV245FT,TC74VHCV245FK  
Octal Schmitt Bus Transceiver  
The TC74VHCV245 is an advanced high speed CMOS OCTAL  
BUS TRANSCEIVER fabricated with silicon gate CMOS  
TC74VHCV245FT  
technology.  
It achieves the high speed operation similar to equivalent Bipolar  
Schottky TTL while maintaining the CMOS low power  
dissipation.  
It is intended for two-way asynchronous communication between  
data busses. The direction of data transmission is determined by  
the level of the DIR input.  
The enable input ( G ) can be used to disable the device so that the  
busses are effectively isolated.  
Input pin and bus terminal have hysteresis between the  
TC74VHCV245FK  
positive-going and negative-going thresholds. Thus the  
TC74VHCV245 is capable of squaring up transitions of slowly  
changing input signals and provides an improved noise immunity.  
Input protection and output circuit ensure that 0 to 5.5 V can be  
(Note)  
applied to the input and output  
pins without regard to the  
supply voltage. These structure prevents device destruction due to  
mismatched supply and input/output voltages such as battery  
back up, etc.  
Note: Output in off-state.

Available in TSSOP and VSSOP (US)  
Power-down protection provided on all inputs and outputs  
Pin and function compatible with the 74 series  
(74AC/VHC/HC/F/ALS/LS etc.) 245 type  
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 levels fixed by means of pull-up or pull-down  
resistors.
