74VHC245  
Octal Bidirectional Transceiver with 3-STATE Outputs  
General Description  
Features  
The VHC245 is an advanced high speed CMOS octal bus  
transceiver fabricated with silicon gate CMOS technology.  
It achieves high speed operation similar to equivalent Bipo-  
lar 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  
device so that the busses are effectively isolated. All inputs  
are equipped with protection circuits against static dis-  
charge.  
High Speed: tPD 4.0 ns (typ) at VCC 5V  
High Noise Immunity: VNIH VNIL 28% VCC (Min)  
Power Down Protection is provided on all inputs  
Low Noise: VOLP 0.9V (typ)  
Low Power Dissipation:
