The 74VHCT574ATTR from STMicroelectronics is an advanced high-speed CMOS Octal D-Type Flip Flop. This 8-bit device is controlled by a clock input and an output enable input. On the positive transition of the clock, the Q outputs are set to logic states that were setup at the D inputs. When the OE input is low, the 8 outputs are in a normal logic state; when high, they are in a high impedance state.
Key electrical specifications include an operating voltage range of 4.5V to 5.5V and a maximum clock frequency of 130 MHz (180 MHz typical). It offers low power dissipation with a quiescent current of 4 µA maximum at 25°C. The device features symmetrical output impedance with |IOH|=|IOL|=8 mA minimum and a maximum propagation delay of 10.6ns at 5V and 50pF.
Designed for high-speed applications, the 74VHCT574ATTR is compatible with TTL outputs and offers improved latch-up immunity. It includes power-down protection on all inputs and outputs, allowing inputs to accept 0 to 7V without regard to the supply voltage, making it suitable for 5V to 3V interfacing. All inputs and outputs are equipped with protection circuits against static discharge, providing 2KV ESD immunity.
The flip-flop is housed in a 20-TSSOP package with a surface mount type. The operating temperature range is -55°C to 125°C.
