74VHC245 74VHCT245  
Octal Bidirectional Transceiver with 3-STATE Outputs  
General Description  
Features  
n High Speed:  
The VHC/VHCT245 is an advanced high speed CMOS octal  
bus transceiver fabricated with silicon gate CMOS technol-  
ogy. It achieves high speed operation similar to equivalent  
Bipolar Schottky TTL while maintaining the CMOS low power  
dissipation. The VHC245 is intended for bidirectional asyn-  
chronous communication between data busses. The direc-  
tion of data transmission is determined by the level of the  
T/R input. The enable input can be used to disable the de-  
vice so that the busses are effectively isolated. All inputs are  
equipped with protection circuits against static discharge.
