  • Latch-based serial port output buffer
    Patent number: 7449924
    Abstract: An integrated circuit (22) having a serial interface (25) with improved access times is disclosed. The serial interface (25) includes a serial output port arranged as a shift register of flip-flop stages (321 through 32n) and a last output latch stage (320). The last output latch stage (320) includes an integral output buffer (33), and as such is constructed differently from the other output flip-flops (321 through 32n), which include master and slave latches. No external output buffer is then required; this last output latch stage (320) directly drives the output terminal and the external serial data line (SDATA).
