The M74HC534B1R is an 8-bit wide flip-flop, designed by STMicroelectronics. It is part of the SCT family of devices, which are designed for use in areas that require high performance, low power, medium-speed requirements. The SCT family includes buffered, unbuffered, and edge-triggered types of flip-flops.

The M74HC534B1R is an 8-bit wide edge-triggered flip-flop, with two flip-flops interconnected in an 8-bit array. Each flip-flop can be driven by a single clock signal. It is an ideal choice for applications where synchronization of serial data streams is a must. This device enables high speed, low power operation, while consuming a very low quiescent current.

The M74HC534B1R is also known as a level-sensitive scan-lock (LSSD) latch, and it uses a single common clock to maintain synchronization between the two data streams. This type of latch is often used in areas where a large number of serial data lines must be synchronized, or in areas where high speed, low power operation is desired.

The application fields for the M74HC534B1R include high-speed digital logic, low-power data exchange, and fast serial data transfer. It is also ideal for time-sensitive logic designs, as it can be synchronized to maintain accurate data streams. This device has a maximum operating temperature of 105°C and is available in both surface-mount and thru-hole packages.

The working principle of the M74HC534B1R is based on two 8-bit latches connected in an array. A single clock signal is used to control the transfer of data between the two latches. The data is sampled on the rising edge of the clock, and is transferred on the falling edge. The flip-flops are dual-edge triggered, meaning they are triggered by a high-to-low transition as well as a low-to-high transition. The clock signal is shown in the timing diagrams.

On the positive edge of the clock signal, the latches synchronize the data and the data is latched into the flip-flops, which are then stored for the next rising edge of the clock. The latches contain a D-type flip-flop, with data , clock , and reset inputs and a Q output. When the reset signal is asserted, the data will be reset and will be stored until the next rising edge of the clock signal. The voltage levels of the data and clock signals must be specified as TTL, CMOS, or LVTTL.

The M74HC534B1R is an ideal device for applications that need high speed, low power operation, and synchronization of multiple serial data streams. Its 8-bit wide edge-triggered array makes it ideal for applications that use multiple data streams and need to ensure that they are synchronized. It is available in surface-mount and thru-hole packages and operates at an extended temperature range.
