Applications
The SN74HC74PWR-P is used in digital systems for data latching, clock synchronization, and frequency division-by-two applications where two independent edge-triggered flip-flops are needed in a single IC. Its 2 V to 6 V supply range enables compatibility with both 3.3 V and 5 V logic families in consumer electronics, industrial control, and communication boards. It is also deployed in shift-register chains, pipeline registers, and handshake synchronizer circuits.

Frequently Asked Questions
Over what supply voltage range does the SN74HC74PWR-P operate?
The SN74HC74PWR-P operates from 2 V to 6 V, covering both 3.3 V and 5 V logic systems. This wide range makes it interoperable with modern low-voltage microcontrollers and legacy 5 V TTL-compatible logic without level-shifting circuitry in most common board designs.
How are the two flip-flop elements triggered, and do they share a clock or reset signal?
Each of the 2 flip-flop elements is triggered on the positive (rising) edge of its own independent clock input, and each has its own dedicated asynchronous set and reset pins. This independence allows two unrelated clock domains to coexist in the same 14-pin TSSOP package without cross-interference.
In which circuit roles is the SN74HC74PWR-P most commonly deployed?
The dual D flip-flop is commonly used as a divide-by-2 frequency divider by feeding the Q-bar output back to the D input, halving an input clock frequency. Other roles include 1-bit data latches in bus interfaces, synchronizer stages for metastability reduction, and pipeline registers where sub-20 ns propagation delay at 5 V is required.
How does the TSSOP package footprint compare to the SOIC option for board layout?
The 14-pin TSSOP package has a 4.40 mm body width versus the wider 3.90 mm or 7.50 mm body of 14-pin SOIC variants, reducing PCB land area by roughly 50%. For dense digital logic boards where multiple flip-flop or gate ICs are packed in proximity, the TSSOP form factor saves significant routing space at no penalty in the 2 V to 6 V operating range.
