Product details
Overview
MC10H141P from ON Semiconductor is a four-bit universal shift register in PDIP-16 package, operating at ≥250 MHz shift frequency with 1.0–2.1 ns propagation delay, −5.2 V VEE supply, and MECL 10K compatibility. It performs parallel entry, shift-left, shift-right, and hold functions without external gating, used in high-speed digital test equipment and ECL-based serial data interfaces.
For engineers reviewing the MC10H141P datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, truth-table–driven mode mapping, thermal-rated AC performance, and direct substitution guidance for legacy MECL timing-critical systems.
Technical Context
The MC10H141P implements four edge-triggered D-type flip-flops with a 1-of-4 decoder controlling S1/S2-selectable modes: parallel load (S1=L, S2=L), shift right (S1=H, S2=L), shift left (S1=L, S2=H), and hold (S1=H, S2=H). All outputs switch on the positive clock edge with guaranteed setup/hold times of 1.5/1.0 ns.
It operates exclusively with negative power supply (VEE = −5.2 V ±5%), requires 50 Ω termination to −2.0 V, and maintains noise margin ≥150 mV across 0°C to +75°C. Input voltage thresholds (VIH/VIL) and output swing (VOH/VOL) are voltage-compensated to sustain signal integrity under varying load and temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Shift Frequency | 250 MHz minimum - enables serial data rates up to 250 Mbps in synchronous link designs. |
| Propagation Delay (tpd) | 1.0–2.1 ns - ensures sub-2 ns timing budget for cascaded register stages in pipeline logic. |
| Power Dissipation | 425 mW typical - fixed quiescent draw independent of clock frequency, simplifying thermal design. |
| Supply Voltage | VEE = −5.2 V ±5% - requires single negative rail; no VCC2 dependency beyond pin 16 biasing. |
| Noise Margin | ≥150 mV over full temp/voltage range - guarantees robust operation in noisy backplane or mixed-signal environments. |
| Input Current (IinH) | 255–510 µA max - defines gate drive loading for upstream MECL drivers and fanout capability. |
| Operating Temp | 0°C to +75°C - validated for commercial-grade instrumentation and telecom line-card applications. |
Pinout & Package
MC10H141P uses a 16-pin plastic dual-in-line package (PDIP-16, Case 648-08), lead-free and RoHS compliant. Pin 1 is VCC1, pin 8 is VEE, pin 16 is VCC2; all power pins require local decoupling per MECL layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VCC1) | Positive supply reference | Bias for internal logic gates; tied to system ground or +0.5 V in standard MECL configurations. |
| 2 (Q2) | Output | Second-stage parallel output; active low true logic level referenced to VEE. |
| 3 (Q3) | Output | Third-stage parallel output; synchronized to rising edge of clock input C. |
| 4 (C) | Clock input | Positive-edge-triggered master clock; requires clean, fast-rising waveform (tr ≤ 2.4 ns). |
| 5 (DR) | Serial data in (right) | Feeds LSB during shift-right mode; must meet VIH/VIL thresholds before clock edge. |
| 6 (D3) | Parallel data input (MSB) | Loads bit 3 during parallel-entry mode; sampled on next clock edge when S1=S2=L. |
| 7 (S2), 9 (S1) | Mode select inputs | Binary-coded control: S1/S2 define functional mode per truth table; both referenced to VEE. |
| 8 (VEE) | Negative supply rail | Main −5.2 V return; requires low-inductance path to minimize ground bounce in high-speed switching. |
| 10 (Q1), 11 (Q0) | Outputs | Q1 = bit 1, Q0 = bit 0; provide full 4-bit parallel output bus aligned to clock edge. |
| 12 (DL), 13 (D0–D2) | Data inputs | DL = serial left-shift input; D0–D2 = parallel bits 0–2; all subject to same input current limits. |
| 14 (D1), 15 (D2) | Parallel data inputs | Complete 4-bit parallel load path; no external latching required due to integrated register architecture. |
| 16 (VCC2) | Secondary supply reference | Used for output stage biasing; typically tied to same node as VCC1 in standard configurations. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar universal shift register applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC10H141FNR2G | Same die, PLLC-20 surface-mount package; 20-pin leadless chip carrier instead of PDIP-16. | Required for automated SMT assembly; lacks through-hole mounting and hand-solderability. | Select MC10H141FNR2G for volume production PCBs where reflow compatibility and board space are critical. |
| SN74AS857N | TTL-compatible 4-bit universal shift register; 35 MHz max shift frequency, +5 V supply, higher power (1.2 W). | Not electrically compatible: different logic family, voltage levels, and timing - requires level-shifting and redesign. | Choose SN74AS857N only if migrating fully to TTL logic domains and accepting 7× lower speed and 3× higher power. |
Compared with MC10H141FNR2G, the MC10H141P offers identical core functionality but enables prototyping and low-volume repair via through-hole mounting; versus SN74AS857N, it delivers 7× higher speed and ECL noise immunity at the cost of negative supply requirement and legacy process constraints.

FAQ
What logic family does the MC10H141P belong to, and is it compatible with older MECL parts?
The MC10H141P is a MECL 10H™ device and is a functional and pinout duplication of the standard MECL 10K™ part. It maintains full DC and AC compatibility with 10K-series components while delivering 100% improvement in propagation delay and maximum operating frequency. No PCB changes are needed when upgrading from 10K to MC10H141P in existing designs.
What are the power supply requirements for the MC10H141P?
The MC10H141P requires a single negative supply: VEE = −5.2 V ±5%, with VCC1 and VCC2 referenced to ground (typically 0 V). It draws approximately 102–112 mA supply current across temperature, resulting in ~425 mW typical power dissipation. Termination resistors must be connected to −2.0 V for proper output operation.
Does the MC10H141P support all four universal shift register modes without external logic?
Yes, the MC10H141P supports parallel entry, shift left, shift right, and hold modes solely through its S1 and S2 select inputs - no external gating or additional logic is required. The truth table in the official datasheet defines exact input conditions for each mode, and all transitions occur on the positive edge of the clock input C.
What is the guaranteed minimum shift frequency and propagation delay for the MC10H141P?
The MC10H141P guarantees a minimum shift frequency of 250 MHz and a propagation delay (tpd) ranging from 1.0 ns (typical at 25°C) to 2.1 ns (max at 75°C). These values are measured under specified conditions: 50 Ω termination to −2.0 V, transverse airflow >500 lfpm, and thermal equilibrium established.
Is the MC10H141P RoHS compliant and lead-free?
Yes, the MC10H141P is Pb-Free, halogen-free, and fully RoHS compliant, as confirmed in the official ON Semiconductor datasheet revision 9 (August 2016). The "G" suffix in ordering codes (e.g., MC10H141PG) explicitly denotes lead-free packaging, and the device meets JEDEC J-STD-609 Category 1 requirements.
