Product details
Overview
HCF4035M013TR from STMicroelectronics is a 4-stage CMOS parallel-in/parallel-out shift register with synchronous parallel entry, serial D/JK input on Stage 1, asynchronous true/complement output control, master-slave flip-flop architecture, and buffered I/O. It operates up to 12 MHz at VDD = 10 V, supports 5–20 V supply, and features ±100 nA max input leakage at 18 V.
For engineers reviewing the HCF4035M013TR datasheet, HCF4035M013TR pinout, HCF4035M013TR application, or HCF4035M013TR equivalent, key selection criteria include asynchronous output polarity control, JK-enabled serial sequencing, static CMOS operation across industrial temperature range (−55°C to +125°C), and DIP-16 package compatibility with legacy board layouts.
Technical Context
The device implements four master-slave D-type flip-flops with independent parallel load capability per stage, controlled by a single P/S (Parallel/Serial) input. Data transfers occur on positive clock edges in both modes.
Asynchronous T/C (True/Complement) control overrides output logic state independently of clock timing, while RESET clears all stages asynchronously. JK inputs on Stage 1 enable toggle or D-mode operation without external gating, supporting binary counters and sequence generators.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 20 V - Enables direct interface with 5 V, 10 V, and 15 V logic systems without level-shifting. |
| Max Clock Frequency | 12 MHz (typ.) at VDD = 10 V - Supports medium-speed serial data shifting and counter applications. |
| Input Leakage Current | ±100 nA max at VDD = 18 V, TA = 25°C - Ensures low power consumption and stable DC bias in battery-backed or high-impedance circuits. |
| Output Drive Strength | ±3.0 mA sink/source at VDD = 15 V - Sufficient to drive multiple CMOS loads or small LED indicators directly. |
| Propagation Delay | 75 ns (min) / 150 ns (max) at VDD = 15 V - Guarantees predictable timing margins in synchronous state machines. |
| Operating Temperature | −55°C to +125°C - Qualified for automotive under-hood, industrial motor control, and aerospace environments. |
Pinout & Package
Package: 16-pin plastic DIP (Dual In-line Package), 0.3-inch width, JEDEC MS-001 compliant. Pin pitch: 2.54 mm. Body dimensions: 20.0 × 6.2 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15, 14, 13 | Q1/Q1̅ to Q4/Q4̅ | True and complement outputs per stage - Enables dual-rail logic sampling or differential bus driving without external inverters. |
| 9, 10, 11, 12 | PI-1 to PI-4 | Parallel data inputs - Allows simultaneous loading of 4-bit words (e.g., BCD digits or control nibbles) on clock edge. |
| 4, 3 | J, K | Serial input logic for Stage 1 - Configurable as D-latch (J=K) or toggle flip-flop (J=K=1), reducing external logic in counters. |
| 6 | CLOCK | Positive-edge-triggered global clock - Synchronizes all register stages; critical for deterministic state transitions in finite-state machines. |
| 7 | P/S | Parallel/Serial mode select - High = parallel load; Low = serial shift (Stages 2–4 operate as D-chain). |
| 2 | T/C | Asynchronous true/complement control - Overrides output polarity instantly, enabling dynamic sign inversion or bus polarity reversal. |
| 5 | RESET | Asynchronous active-low reset - Clears all four stages to logic 0 regardless of clock or mode state. |
| 8 | VSS | Negative supply reference - Must be connected to system ground; defines all voltage thresholds. |
| 16 | VDD | Positive supply rail - Supplies internal logic and output drivers; supports wide-range operation up to 20 V. |
Key Features
| Feature | Design Value |
|---|---|
| Asynchronous T/C Output Control | Enables real-time polarity inversion of all four outputs without clock dependency-critical for dynamic bus signaling and test-mode toggling. |
| JK Input on First Stage | Supports both D-latch and toggle behavior in serial mode, eliminating external XOR gates in ring counters or Johnson counters. |
| Static CMOS Operation | Zero static current draw at steady state-ideal for low-power hold modes and energy-sensitive embedded systems. |
| Symmetric Output Drive | Matched rise/fall times (40–80 ns) and equal sourcing/sinking capability ensure clean signal integrity on shared buses. |
| 100% Quiescent Current Tested | Guarantees worst-case IDD ≤ 3000 µA at VDD = 20 V and TA = 125°C-supports thermal design validation in sealed enclosures. |
Applications

Use Value: Maintains mechanical and electrical compatibility with existing PCBs while improving noise margin and temperature range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 4-stage parallel-load shift register applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4035BE | Same pinout and logic function but lower max fCLK (6 MHz @ 10 V); wider propagation delay spread (250–500 ns). | Limited to lower-speed industrial timers and simple sequencers where timing margin is relaxed. | Prefer when cost sensitivity outweighs speed or temperature range requirements. |
| MC14035BDR2G | Identical AC/DC specs and pinout; same JEDEC B-series compliance; minor packaging variation (SOIC-16 only). | No DIP option available; requires rework for through-hole designs. | Select for new SOIC-based designs requiring second-source availability and RoHS compliance. |
Compared with CD4035BE and MC14035BDR2G, HCF4035M013TR offers superior speed (12 MHz vs. 6 MHz), extended temperature range (−55°C to +125°C vs. −40°C to +85°C), and guaranteed DIP-16 packaging-making it optimal for high-reliability, mixed-voltage, and legacy-compatible deployments.

FAQ
Can HCF4035M013TR operate reliably at 20 V supply?
Yes. The device is rated for VDD = 3 V to 20 V per JEDEC JESD13B, with quiescent current fully characterized up to 20 V (3000 µA max at 125°C). Absolute maximum rating is 22 V, but operation above 20 V voids parametric guarantees and risks long-term reliability.
What is the function of the T/C pin when held low?
When T/C is low, all four output pairs (Q1/Q1̅ to Q4/Q4̅) deliver complemented values-i.e., Q1 = NOT(Q1_reg), Q1̅ = Q1_reg, etc. This occurs asynchronously, meaning output polarity flips immediately without waiting for the next clock edge.
Does the HCF4035M013TR support mixed-voltage operation (e.g., 5 V inputs with 15 V VDD)?
Yes. Input voltage limits are specified as 0 V to VDD, so 5 V logic signals are fully compatible with 15 V VDD operation. VIH and VIL thresholds scale with VDD (e.g., VIH = 11 V min at VDD = 15 V), ensuring noise-immune switching across supply voltages.
How does the JK input differ from standard D-input shift registers?
The JK input on Stage 1 allows toggle (J=K=1) or set/reset (J=1/K=0 or J=0/K=1) behavior without external combinational logic. When J and K are tied together, it functions as a D input-providing flexibility for counters, dividers, and programmable sequence generators not possible with basic D-type registers.
