SN74LVC574ADBR Description

Short technical summary and product information.

The SN74LVC574ADBR from Texas Instruments is an octal edge-triggered D-type flip-flop designed for 1.65V to 3.6V VCC operation. This device features 3-state outputs suitable for driving capacitive or low-impedance loads, making it ideal for buffer registers, I/O ports, and bidirectional bus drivers.

 

Key electrical characteristics include a maximum clock frequency of 150 MHz and a maximum propagation delay of 6.8 ns at 3.3V and 50pF. The flip-flop supports mixed-mode signal operation, allowing 5V input/output voltage with a 3.3V VCC, and includes partial power-down support via Ioff circuitry. ESD protection exceeds 2000V (HBM), and latch-up performance is greater than 250 mA per JESD 17.

 

This component is specified for operation from -40°C to 125°C (TA). It is available in a 20-SSOP package, designed for surface mounting. The outputs are tri-state and non-inverted.
