Octal Registered Transceiver with Parity and Flags  
General Description  
Features  
The 74F552 octal transceiver contains two 8-bit registers  
for temporary storage of data flowing in either direction.  
Each register has its own clock pulse and clock enable  
input as well as a flag flip-flop that is set automatically as  
the register is loaded. The flag output will be reset when  
the output enable returns to HIGH after reading the output  
port. Each register has a separate output enable control for  
its 3-STATE buffer. The separate Clocks, Flags, and  
Enables provide considerable flexibility as I/O ports for  
demand-response data transfer. When data is transferred  
from the A Port to the B Port, a parity bit is generated. On  
the other hand, when data is transferred from the B Port to  
the A Port, the parity of input data on B0–B7 is checked.  
8-Bit bidirectional I/O Port with handshake
