HD74HCT245  
Octal Bus Transceivers (with 3-state outputs)  
REJ03D0665–0200  
(Previous ADE-205-554)  
Rev.2.00  
Mar 30, 2006  
Description  
This device has an active low enable input G and a direction control input (DIR). When DIR is high, data flows from  
the A inputs to the B outputs. When DIR is low, data flows from the B inputs to the A outputs. The HD74HCT245  
transfers true data from one bus to the other.  
This device does not have schmitt trigger inputs.

2. Waveform– A is for an output with internal conditions such that the  
output is low except when disabled by the output control.  
3. Waveform– B is for an output with internal conditions such that the  
output is high except when disabled by the output control.  
4. The output are measured one at a time with one transition per measurement.
