What are the key features of CD74HC175EE4?
- 4 independent D-type flip-flops with positive-edge clock trigger and asynchronous active-low clear for synchronous data registration in digital systems
- 20 MHz maximum toggle frequency at 5 V supply enables reliable data latching in medium-speed bus interface and pipeline register applications
- HC CMOS family with 2 V to 6 V supply range and 50 pF load drive, directly interoperable with 3.3 V and 5 V logic without level translators
What is CD74HC175EE4 used for?
The CD74HC175EE4 is commonly used in bus interface registers, pipeline data latches, and state machine feedback paths in digital control boards and FPGA companion circuits. Its four independent flip-flops with shared clock and clear allow 4-bit data words to be registered on a single clock edge, simplifying synchronous handshake logic in parallel bus designs. The 16-pin PDIP package is well suited for prototyping and educational platforms where through-hole mounting on breadboards or DIP sockets is preferred.

Frequently Asked Questions
What is the maximum operating frequency of the CD74HC175EE4, and what clock edge triggers the flip-flops?
The CD74HC175EE4 is rated for a maximum toggle frequency of 20 MHz at a 5 V supply with a 50 pF load, and all four flip-flops capture their D inputs on the rising (positive) edge of the shared clock signal, making them suitable for synchronous data registration in medium-speed digital pipelines.
How does the asynchronous clear function on the CD74HC175EE4 work in a system reset context?
Asserting the active-low asynchronous clear pin drives all four Q outputs to logic 0 immediately, independent of the clock, allowing the CD74HC175EE4 to be reset during system power-on via a supervisor RC circuit or a microcontroller GPIO without waiting for a clock edge, which is critical for deterministic state initialization.
Can the CD74HC175EE4 operate in a 3.3 V logic system alongside 5 V peripherals?
Yes, the HC CMOS family accepts supply voltages from 2 V to 6 V, so the CD74HC175EE4 can run at 3.3 V where its VIH threshold is approximately 2.31 V (70% of VCC), which is compatible with 3.3 V CMOS outputs; for mixed 3.3 V/5 V boards, a level translator is recommended on the 5 V output side to prevent exceeding the 3.3 V input clamping limit.
What data bus widths can be handled by combining multiple CD74HC175EE4 devices?
Each CD74HC175EE4 registers 4 bits; connecting two devices to a shared clock and clear line creates an 8-bit parallel register, and four devices create a 16-bit register, with the only external wiring being the common CLK and CLR signals, making it straightforward to scale from 4-bit to 16-bit synchronous data capture in bus interface designs.
Is the CD74HC175EE4 in PDIP a drop-in replacement for the 74LS175 in legacy through-hole designs?
The CD74HC175EE4 is pin-compatible with the 74LS175 in a 16-pin DIP footprint, and its HC CMOS inputs accept 74LS-level logic outputs (VOH ≥ 2.7 V), so it can replace 74LS175 on existing PCBs and reduce quiescent supply current from roughly 24 mA (LS) to under 1 µA (HC), extending battery life in portable legacy equipment.
