M74HC299 Datasheet (ST Microelectronics) - 8-BIT PIPO SHIFT REGISTER

M74HC299, 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
