STMicroelectronics M54HC75
The M54HC75 is an high speed CMOS 4 BIT D TYPE LATCH fabricated with silicon gate C2MOS technology. It contains two groups of 2 bit latches controlled by an enable input (G1•2 or G3•4). These two latch groups can be used in different circuits.| Part No. | M54HC75 |

DESCRIPTION
Each latch has Q and Q outputs (1Q - 4Q and 1Q - 4Q). The data applied to the data input is transferred to the Q and Q outputs when the enable input is taken high and the outputs will follow the data input as long as the enable input is kept high. When the enable input is taken low, the information data applied to the data input is retained at the outputs. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
