INTEGRATED CIRCUITS 74F552 Octal registered transceiver with parity and flags (3-State) Product specification IC15 Data Handbook 1991 Jan 02 Philips Semiconductors Philips Semiconductors Octal registered transceiver with parity and flags (3-State) Product specification 74F552 FEATURES 8-bit bidirectional I/O port with handshake Register status flag flip-flops Separate clock enable and output enable Parity generation and parity check B outputs and parity output sink 64mA DESCRIPTION The 74F522 Octal Registered Transceiver contains two 8-bit registers for temporary storage of data flowing in either direction. Each register has its own clock (CPR, CPS) and Clock Enable (CER, CES) inputs, 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 (OEAS, OEBR) for its 3-State buffer. The separate Clock...
