SN74HC574NSR Description

Short technical summary and product information.

The SN74HC574NSR from Texas Instruments is an octal edge-triggered D-type flip-flop designed for bus driving applications. It features 3-state noninverting outputs capable of driving bus lines directly or up to 15 LSTTL loads.

This device operates with a wide supply voltage range of 2 V to 6 V and has a maximum clock frequency of 40 MHz. The typical propagation delay is 31 ns at 6 V with a 50 pF load. It consumes low power, with a maximum ICC of 80 µA and a low input current of 1 µA.

The SN74HC574NSR is suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. It is available in a 20-SOIC surface mount package.

Key electrical characteristics include a ±6 mA output drive at 5 V and an input capacitance of 3 pF. The operating temperature range is -40°C to 85°C.
