MC74LCX574DTG

The MC74LCX574DTG from ON Semiconductor is a high-performance, non-inverting octal D-type flip-flop. It operates from a supply voltage range of 2.3V to 3.6V. The device features 5V tolerant inputs and outputs, enabling seamless interface capability with 5V TTL logic. Its high-impedance TTL-compatible inputs minimize current loading on input drivers, while TTL-compatible outputs provide improved switching noise performance.

This flip-flop consists of eight edge-triggered flip-flops with individual D-type inputs and 3-state true outputs. The buffered clock and buffered Output Enable (OE) are common to all flip-flops. The eight flip-flops store the state of individual D inputs on the LOW-to-HIGH Clock (CP) transition, provided setup and hold time requirements are met. When OE is LOW, the contents of the flip-flops are available at the outputs. When OE is HIGH, the outputs enter a high-impedance state.

The MC74LCX574DTG is supplied in a TSSOP-20 package, suitable for surface mount applications. It supports live insertion and withdrawal, and features an IOFF specification that guarantees high impedance when VCC is 0V. The device is Pb-free, Halogen Free/BFR free, and RoHS compliant.
