M54HC299 - 8-BIT PIPO SHIFT REGISTER
The M54/74HC299/323 are high speed CMOS 8BIT PIPO SHIFT REGISTERS (3-STATE) fabricated with silicon gate C2MOS technology.
They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power consumption.
These devices have four modes (HOLD, SHIFT LEFT, SHIFT RIGHT
