Product details
Overview
HEF40175BT,652 from Nexperia is a quad positive-edge-triggered D-type flip-flop in SO16 (SOT109-1) package, featuring four independent D inputs, one shared clock (CP), active-low master reset (MR), and complementary buffered Q/Q̅ outputs per stage. It operates across 3.0 V to 15.0 V supply, supports -40 °C to +125 °C ambient range, and delivers 45 MHz max frequency at 15 V for synchronous data latching in digital control logic.
For engineers reviewing the HEF40175BT,652 datasheet, HEF40175BT,652 pinout, HEF40175BT,652 application, or HEF40175BT,652 equivalent, this device serves as a robust, wide-VDD CMOS storage element for shift registers, pattern generation, and buffer register functions where rail-to-rail input compatibility and high noise immunity are required.
Technical Context
The HEF40175BT,652 implements four identical edge-triggered D flip-flops with asynchronous active-low reset, enabling simultaneous clearing of all Q outputs to LOW (Q̅ to HIGH) regardless of clock or data state. Each stage meets set-up (5 ns min at 15 V) and hold (0 ns min) timing requirements relative to the LOW-to-HIGH CP transition.
Its static CMOS architecture ensures zero DC current draw during steady-state operation, while input clamp diodes allow safe interfacing to voltages beyond VDD when used with current-limiting resistors. Propagation delays scale predictably with load capacitance: tPHL/tPLH = 17 ns + (0.16 ns/pF) × CL at 15 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage (VDD) | 3.0 V to 15.0 V - enables direct interface with 5 V, 10 V, and 15 V logic systems without level shifting. |
| Operating temperature | -40 °C to +125 °C - qualified for industrial and extended-temperature embedded control applications. |
| Max clock frequency | 45 MHz at VDD = 15 V - supports high-speed synchronous data capture in pattern generators and shift registers. |
| Propagation delay (CP to Q) | 25 ns to 50 ns at 15 V (CL = 50 pF) - defines worst-case timing margin for downstream logic synchronization. |
| Output drive strength | IOL = 2.4 mA / IOH = −2.4 mA at VDD = 15 V - sufficient to drive ≥10 4000-series CMOS loads or moderate capacitive bus lines. |
| Input clamp protection | HBM ESD >2000 V, CDM >1000 V - allows robust handling and board-level integration without additional transient suppression. |
| Quiescent supply current | 120 μA max at VDD = 15 V, +125 °C - ensures low static power in battery-backed or energy-sensitive systems. |
Pinout & Package
HEF40175BT,652 uses the SO16 plastic small outline package (SOT109-1), 16-pin, 3.9 mm body width, with standard 1.27 mm lead pitch and gull-wing leads suitable for reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | MR | Asynchronous master reset (active LOW); forces all Qn = LOW, Q̅n = HIGH independent of CP or Dn. |
| 2, 7, 10, 15 | Q0–Q3 | Buffered true outputs; each sourced from one D-flip-flop stage, capable of driving CMOS/TTL loads. |
| 3, 6, 11, 14 | Q̅0–Q̅3 | Complementary buffered outputs; provides inverted logic states for dual-rail signaling or feedback paths. |
| 4, 5, 12, 13 | D0–D3 | Data inputs; sampled on LOW-to-HIGH CP edge if set-up/hold times met; include internal clamp diodes. |
| 8 | VSS | Ground reference for all internal circuitry and I/O; must be low-impedance connection to system GND plane. |
| 9 | CP | Clock input; edge-triggered (LOW-to-HIGH); synchronizes D-input sampling across all four flip-flops. |
| 16 | VDD | Positive supply rail; supports 3–15 V operation; decoupling capacitor (100 nF) recommended near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VDD range (3–15 V) | Eliminates need for separate voltage regulators in mixed-supply systems; compatible with legacy 5 V and modern 12 V industrial rails. |
| Fully static CMOS design | Zero static current draw at stable logic states - critical for low-power hold modes and battery-operated control sequencers. |
| Input clamp diodes | Enables safe overvoltage tolerance up to VDD + 0.5 V using external series resistors - simplifies interface to sensors or legacy logic families. |
| Symmetrical output characteristics | Matched rise/fall times and drive strength for Q and Q̅ outputs - ensures precise timing in toggle, enable, or differential feedback circuits. |
| JEDEC JESD13-B compliance | Guarantees interoperability with industry-standard CMOS logic families and PCB layout practices across global manufacturing sites. |
Applications
| Shift Registers | Buffer/Storage Register |

Use Value: Provides deterministic, glitch-free hold with no clock skew between channels; 125 °C rating ensures reliability in enclosed control cabinets. |
| Pattern Generator | Digital Control Sequencer |
Use Scenario: Generating fixed test waveforms (e.g., PWM duty cycle sweeps or address strobes) for automated functional testing of ASICs. IC Role / Device Role / Timing Role: Configured as a 4-bit Johnson counter via Q̅-to-D feedback; CP drives waveform period, MR resets sequence start point. Use Value: Delivers repeatable, jitter-free patterns without software overhead; 15 V operation ensures clean edges into 50 Ω test fixtures. |
Use Scenario: State retention in a safety-critical motor controller, where MR is tied to hardware fault signal to force known-safe output states. IC Role / Device Role / Timing Role: Latches enable/disable commands from FPGA logic; MR provides fail-safe override that overrides clock and data unconditionally. Use Value: Guarantees Q = LOW on fault detection within <50 ns (tPLH max), meeting SIL-2 response time requirements for industrial drives. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD40175BE | Same pinout and function but rated only to +85 °C; lacks JESD13-B compliance and has higher propagation delay (120 ns typ @ 5 V). | Not suitable for automotive under-hood or industrial high-temp environments requiring +125 °C operation. | Select only for cost-sensitive, non-extended-temperature consumer designs where JEDEC compliance is not mandated. |
| 74HC175PW,118 | Higher speed (115 MHz @ 5 V) but narrower VDD range (2–6 V); TSSOP16-only packaging; no input clamps. | Requires level-shifting for >6 V systems; lacks overvoltage protection needed in noisy industrial I/O zones. | Prefer for high-speed 3.3 V/5 V digital systems with tight timing budgets and clean supply rails. |
Compared with CD40175BE and 74HC175PW,118, the HEF40175BT,652 uniquely balances wide-voltage operation, extended temperature capability, and built-in input protection-making it the only choice for ruggedized 5–15 V control logic where reliability trumps raw speed.

FAQ
What is the minimum pulse width required on the MR pin to ensure reliable reset?
The datasheet specifies a minimum MR LOW pulse width of 10 ns at VDD = 15 V and 25 °C. At +125 °C, this increases to 20 ns due to process variation. To guarantee reset across full temperature and voltage range, design for ≥25 ns MR LOW duration with clean, monotonic edges and no overshoot exceeding VDD + 0.5 V.
Can HEF40175BT,652 operate reliably at 3.3 V supply?
Yes - the device is fully specified down to 3.0 V VDD. At 3.3 V, typical fmax drops to ~12 MHz, tPHL/tPLH extends to ~140 ns (CL = 50 pF), and VOH/VOL remain rail-aligned (VOH ≥ 3.2 V, VOL ≤ 0.1 V). Input thresholds scale proportionally (VIH ≈ 2.2 V, VIL ≈ 1.1 V), ensuring compatibility with 3.3 V CMOS drivers.
Is the SO16 package (SOT109-1) RoHS compliant and lead-free?
Yes - HEF40175BT,652 is manufactured in a RoHS-compliant, lead-free process per EU Directive 2011/65/EU. The SOT109-1 package uses matte tin (Sn) termination finish with no lead content, and all materials meet Nexperia's substance restrictions policy (including halogen-free epoxy molding compound).
How does the input clamp diode affect interfacing with 24 V sensor signals?
The internal clamp diodes allow safe connection of 24 V signals to D or CP pins when a series current-limiting resistor ≥10 kΩ is used. At 24 V, the diode conducts excess voltage to VDD, limiting pin voltage to VDD + 0.5 V. This avoids external protection components while maintaining valid logic levels - provided VDD remains stable and the resistor limits current to <10 mA per diode.
