M74HC77 Datasheet (ST Microelectronics)

M74HC77, 4-BIT D-TYPE LATCH

The M54/74HC77 is a high speed CMOS 4-BIT DTYPE LATCH fabricated in silicon gate C2MOS technology.

It has the same high speed performance of LSTTL combined with true CMOS low power consumption.

It contains two groups of 2-bit latches controlled by an enable input (G1 * 2 or G3 * 4).
