MITSUBISHI M54995P/FP Bi-CMOS 8-BIT SERIAL-INPUT LATCHED DRIVER DESCRIPTION The M54995 is a semiconductor integrated circuit consisting of 8 stages of CMOS shift registers and latches with serial inputs and serial or parallel outputs. It is based on Bi-CMOS process technology, and has 8 bipolar drivers at the parallel outputs.

For parallel output. When the clock pulse changes from low to high, latch input (LATCH) is high and output enable input (EN) is low the serial input data at S-IN appears at output O1 and the other data already present is shifted sequentially to outputs O2 through O8. The parallel outputs are inverted. When the latch input is held low, the latch retains the stored data. When the EN input is high, outputs O1 through O8 all turn...
