Product details
Overview
SN65EPT23DGKR from Texas Instruments is a dual 3.3 V differential LVPECL/LVDS-to-LVTTL/LVCMOS translator IC used for high-speed clock and data level conversion in backplane and timing-critical systems. It delivers 24 mA LVTTL outputs, supports >300 MHz switching frequency, features 2.0 ns typical propagation delay, and operates across –40°C to +85°C with VCC = 3.0–3.6 V.
For engineers reviewing the SN65EPT23DGKR datasheet, SN65EPT23DGKR pinout, SN65EPT23DGKR application, or SN65EPT23DGKR equivalent, this device serves as a drop-in-compatible replacement for MC100EPT23 in high-frequency signal integrity designs requiring precise differential-to-single-ended translation with built-in input biasing and temperature compensation.
Technical Context
The SN65EPT23DGKR integrates two independent differential input channels (D0/D0̅, D1/D1̅) accepting LVPECL, LVDS, or CML signals, each driving a dedicated LVTTL/LVCMOS output (Q0, Q1). Input common-mode range spans 1.2 V to 3.3 V, and internal 50 kΩ pull-up/pull-down resistors maintain valid logic states on floating inputs.
It employs a low-power design with supply current of 15–25 mA per output state, achieves 110 ps max output-to-output skew, and maintains <10 ps RMS random jitter at 300 MHz - enabling deterministic timing in synchronous backplane interfaces and clock distribution networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 3.0 V to 3.6 V - ensures compatibility with standard 3.3 V logic rails and tolerance to power supply ripple. |
| Max Switching Frequency | 300 MHz - guarantees functional operation for high-speed clock/data transmission in telecom and computing backplanes. |
| Propagation Delay | 1.1–1.9 ns - enables sub-2 ns timing budget allocation in critical path synchronization. |
| LVTTL Output Drive | 24 mA sink/source - meets LVTTL interface requirements while driving 500 Ω loads with VOH ≥2.4 V and VOL ≤0.5 V. |
| Input Voltage Swing | 150–1200 mV - supports full logic swing translation from low-amplitude LVDS up to robust LVPECL inputs. |
| Operating Temperature | –40°C to +85°C - qualified for industrial and extended-temperature embedded applications. |
| ESD Rating | HBM: 2 kV - provides baseline ESD robustness for handling and board assembly without special precautions beyond standard IC practices. |
Pinout & Package
VSSOP-8 (DGK) package: 3.0 mm × 3.0 mm body, 0.65 mm pitch, 1.1 mm max height, exposed thermal pad optional, RoHS-compliant NiPdAu lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (D0) | Differential LVPECL/LVDS Input (+) | Non-inverting input for first channel; internally biased to VCC/2 when open. |
| 2 (D0̅) | Differential LVPECL/LVDS Input (–) | Inverting input for first channel; complements D0 for noise-rejecting differential reception. |
| 3 (D1) | Differential LVPECL/LVDS Input (+) | Non-inverting input for second channel; identical biasing and AC characteristics as D0. |
| 4 (D1̅) | Differential LVPECL/LVDS Input (–) | Inverting input for second channel; matches D1 for matched pair routing. |
| 5 (GND) | Ground Reference | Primary return path for all internal circuitry and output drivers; must be low-impedance. |
| 6 (Q0) | LVTTL/LVCMOS Output | Single-ended output corresponding to D0/D0̅ pair; 24 mA drive strength, rail-to-rail swing. |
| 7 (Q1) | LVTTL/LVCMOS Output | Single-ended output corresponding to D1/D1̅ pair; electrically isolated from Q0 with <110 ps skew. |
| 8 (VCC) | Positive Supply | 3.3 V core and I/O supply; decoupling capacitor required within 1 cm for stable high-frequency operation. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel translation | Enables simultaneous clock and data path conversion without cross-talk or shared timing paths. |
| Built-in input biasing | 50 kΩ internal pull-up/pull-down resistors eliminate need for external termination on unused or floating inputs. |
| Temperature-compensated design | Maintains consistent propagation delay and output thresholds across –40°C to +85°C operating range. |
| Drop-in compatibility with MC100EPT23 | Same pinout, function, and performance envelope allows legacy design reuse without layout changes. |
| Low-skew outputs | 110 ps max Q0–Q1 skew ensures tight timing alignment for parallel data lanes or dual-clock domains. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential-to-single-ended translator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN65LVEP23DGKR | Supports wider VCC range (2.3–3.6 V), lower power (12 mA typical), but no internal input biasing resistors. | Preferred for battery-powered or ultra-low-power systems where external termination is acceptable. | Select SN65LVEP23DGKR only if supply voltage may dip below 3.0 V or if external biasing is already implemented. |
| MC100EPT23DG | Identical pinout and function, but obsolete status, limited availability, and no MSL-1 reflow rating. | Suitable only for legacy repair or small-batch replacement where TI part qualification is not required. | Prefer SN65EPT23DGKR for new designs due to active production status, guaranteed supply, and enhanced manufacturability. |
Compared with SN65LVEP23DGKR and MC100EPT23DG, the SN65EPT23DGKR offers optimal balance of industrial temperature support, integrated biasing, and active supply chain assurance - making it the recommended choice for volume production in timing-critical infrastructure.

FAQ
What is the maximum operating frequency supported by the SN65EPT23DGKR?
The SN65EPT23DGKR supports clock frequencies up to 300 MHz, as verified across its full operating temperature range (–40°C to +85°C) and VCC range (3.0 V to 3.6 V). This specification ensures functional correctness for high-speed backplane and data transmission applications, though DC output voltage levels (VOH/VOL) are guaranteed only at static conditions.
Does the SN65EPT23DGKR require external termination resistors on its differential inputs?
No, the SN65EPT23DGKR does not require external termination resistors on its D0/D0̅ or D1/D1̅ inputs because it includes internal 50 kΩ pull-up and pull-down resistors that bias floating inputs to valid logic states. This feature simplifies PCB layout and reduces component count in space-constrained designs.
Is the SN65EPT23DGKR pin-compatible with the MC100EPT23?
Yes, the SN65EPT23DGKR is explicitly designed as a drop-in compatible replacement for the MC100EPT23, sharing identical pinout, electrical specifications, and functional behavior. TI confirms this compatibility in the official datasheet, enabling seamless migration without PCB redesign.
What package type is used for the SN65EPT23DGKR, and what are its key mechanical dimensions?
The SN65EPT23DGKR uses the VSSOP-8 (DGK) package: 3.0 mm × 3.0 mm body size, 0.65 mm lead pitch, 1.1 mm maximum height, and RoHS-compliant NiPdAu lead finish. Its compact footprint supports high-density routing in space-constrained applications such as modular test equipment and industrial PLC modules.
Can the SN65EPT23DGKR operate with a 2.5 V supply voltage?
No, the SN65EPT23DGKR requires a minimum VCC of 3.0 V and is specified only for operation between 3.0 V and 3.6 V. Using 2.5 V violates the absolute minimum supply rating and will result in undefined output behavior, potential logic failure, and noncompliance with AC/DC specifications including propagation delay and output drive strength.
