MM74HCT574MTC

The MM74HCT574MTC from ON Semiconductor is an octal D-type flip-flop built with advanced silicon-gate CMOS technology. It offers inherent benefits of low power consumption and a wide power supply range while maintaining LS-TTL input and output characteristic compatibility. This device features 3-state outputs capable of driving 15 LS-TTL loads.

The flip-flop is positive edge-triggered, meaning data at the D inputs is transferred to the Q outputs on the positive-going transitions of the Clock (CK) input. The Output Control (OC) input, when high, places all outputs into a high impedance state. All inputs are protected against static discharge damage.

Key electrical specifications include a typical propagation delay of 17 ns, a maximum propagation delay of 30ns at 5V and 50pF, and a clock frequency of up to 33 MHz. It operates within a temperature range of -40°C to 85°C.

Packaged in a 20-TSSOP, the MM74HCT574MTC is suitable for surface mounting. Its design makes it an ideal plug-in replacement for LS-TTL devices, potentially reducing power consumption in existing designs and interfacing between TTL, NMOS, and standard CMOS components.
