Octal Registered Transceiver with Parity and Flags
General Description
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 B
