The 74LV574 is a low-voltage Si-gate CMOS device and is pin and function compatible with 74HC/HCT574. The 74LV574 is an octal D-type flip–flop featuring separate D-type inputs for each flip-flop and non-inverting 3-state outputs for bus oriented applications.
The Philips 74LV574 is a low-voltage Si-gate CMOS device designed as an octal D-type flip-flop. It features separate D-type inputs for each of the eight flip-flops and non-inverting 3-state outputs, making it suitable for bus-oriented applications where multiple devices share common lines.
The device operates with a wide voltage range from 1.0V to 5.5V and is optimized for low-voltage applications between 1.0V and 3.6V. It includes a common clock (CP) input and an output enable (OE) input shared by all flip-flops, allowing for synchronized data storage and controlled bus driving capabilities.
| Operating Voltage Range | 1.0 to 5.5V |
|---|---|
| Low Voltage Optimization | 1.0 to 3.6V |
| Propagation Delay (Typical) | < 2.5 ns |
| Input Capacitance | 3.5 pF |
The typical output ground bounce (Vo_p) is less than 0.8V at Voc = 3.3V.
The device features a common 3-State output enable input and has an output capability of a bus driver.
