High Performance Silicon Gate CMOS

Transcription

1 SEMIONUTOR TENI T igh Performance Silicon Gate MOS The M74 is identical in pinout to the S. The device inputs are compatible with standard MOS outputs, with pull up resistors, they are compatible with STT outputs. This static shift register features parallel load, serial load (shift right), hold, and reset modes of operation. These modes are tabulated in the Function Table, and further explanation can be found in the Pin escription section.
