Product details
Overview
PCA82C250T/YM,115 from NXP Semiconductors is a high-speed CAN transceiver IC that serves as the physical layer interface between a CAN protocol controller (e.g., SJA1000, P8xC592) and the differential CAN bus. It delivers differential transmit and receive capability, supports up to 1 MBd data rate, operates from 4.5 V to 5.5 V, and features thermal protection, short-circuit immunity to battery/ground, and ±8 V to +18 V bus voltage tolerance - enabling robust use in automotive powertrain and body control modules.
For engineers reviewing the PCA82C250T/YM,115 datasheet, PCA82C250T/YM,115 pinout, PCA82C250T/YM,115 application, or PCA82C250T/YM,115 equivalent, this page provides verified technical context, SO8 package mapping, slope-control mode configuration, ISO 11898 compliance confirmation, and validated alternative transceivers for automotive CAN network design.
Technical Context
The PCA82C250T/YM,115 implements a fully differential transmitter with programmable slew rate via Rs pin (Pin 8), enabling High-speed, Slope-control, or Standby modes. Its receiver features wide common-mode range (−8 V to +18 V on CANH/CANL) and 150 mV hysteresis for EMI resilience in noisy automotive environments.
Thermal protection activates at ~160 °C junction temperature, reducing transmitter current without disabling receiver operation. Bus fault tolerance includes transient protection per ISO 7637-2 pulses 1, 2, 3a, and 3b, and ESD robustness of ±2 kV HBM.
Key Specifications

| Supply Voltage | 4.5 V to 5.5 V - compatible with standard automotive 5 V rail and tolerant of load-dump transients. |
| Standby Current | ≤170 µA - minimizes quiescent power in sleep-mode vehicle networks. |
| Differential Output Voltage | 1.5 V to 3.0 V - ensures reliable dominant/recessive state detection across ≥110 nodes. |
| Ambient Temperature Range | −40 °C to +125 °C - qualified for under-hood and chassis-mounted automotive applications. |
| Common-Mode Input Range | −8 V to +18 V - maintains functionality during battery disconnect, jump-start, or alternator load dump. |
| Propagation Delay | ≤50 ns - supports timing-critical CAN FD pre-qualification and legacy high-speed CAN timing budgets. |
Pinout & Package
PCA82C250T/YM,115 is housed in an SO8 plastic small outline package (SOT96-1), 3.9 mm body width, 1.27 mm lead pitch, with gull-wing leads suitable for reflow soldering per J-STD-020C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TXD (Pin 1) | Transmit Data Input | CMOS-level input from CAN controller; drives bus dominant/recessive states. |
| GND (Pin 2) | Ground Reference | Primary return path for supply, bus, and logic circuits; must be low-impedance in vehicle harness layout. |
| VCC (Pin 3) | Power Supply | 5 V nominal supply; decoupling capacitor (100 nF) required per datasheet Figure 9. |
| RXD (Pin 4) | Receive Data Output | CMOS-level output to controller; active-low dominant indication with 3 µs wake-up latency in Standby mode. |
| Vref (Pin 5) | Reference Voltage Output | 0.5 × VCC (±10%) - used for external comparator bias or bus termination monitoring. |
| CANL (Pin 6) | CAN Low Bus Line | Differential bus terminal; withstands −8 V to +18 V; requires 124 Ω termination at network ends. |
| CANH (Pin 7) | CAN High Bus Line | Differential bus terminal; complements CANL; same voltage rating and transient immunity. |
| Rs (Pin 8) | Slope/Standby Control | Configures operation mode: grounded = High-speed; 47 kΩ to GND = Slope-control; >0.75×VCC = Standby. |
Key Features
| Feature | Design Value |
|---|---|
| ISO 11898-2 Compliance | Fully compliant physical layer implementation - ensures interoperability with all standard high-speed CAN nodes. |
| Three-Mode Rs Control | Selectable High-speed (fast edge), Slope-control (RFI reduction), or Standby (170 µA) via single external resistor or logic level. |
| Bus Fault Protection | Withstands −150 V to +100 V transients (ISO 7637-2) and short-circuit to battery/ground without latch-up or damage. |
| Differential Receiver Immunity | 150 mV hysteresis and >20 kΩ differential input resistance - rejects common-mode noise in 12 V/24 V vehicle electrical systems. |
| Thermal Foldback | Reduces transmitter current above ~160 °C junction temperature - prevents thermal runaway during sustained bus shorts. |
Applications
| Engine Control Unit (ECU) | Anti-lock Braking System (ABS) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CAN transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TJA1042T/3/1 | Lower standby current (≤30 µA), integrated wake-up filter, no Vref output, higher ESD rating (±6 kV contact). | Better suited for ultra-low-power gateway modules requiring selective wake-up; lacks Vref for external monitoring. | Choose TJA1042T/3/1 when optimizing for sleep-mode current or enhanced ESD robustness; verify Vref dependency in existing designs. |
| MCP2551-I/P | 5 V only (no 4.5 V min), no Standby mode, higher propagation delay (≤120 ns), no thermal foldback. | Legacy industrial CAN networks where cost and simplicity outweigh automotive-grade fault tolerance. | Select MCP2551-I/P for non-automotive 5 V systems with relaxed timing and thermal requirements; avoid in ASIL-relevant domains. |
Compared with PCA82C250T/YM,115, TJA1042T/3/1 reduces standby power by 82% but removes Vref functionality, while MCP2551-I/P sacrifices thermal protection and bus fault margin for lower BOM cost in non-automotive settings.

FAQ
What is the maximum bus data rate supported by the PCA82C250T/YM,115?
The PCA82C250T/YM,115 supports a maximum bus data rate of 1 MBd in High-speed mode, as confirmed in Table 1 (Quick reference data) and functional description section. This rate is achievable with proper termination (124 Ω), controlled slew rate, and shielded cabling - making PCA82C250T/YM,115 suitable for demanding automotive applications such as engine control and ABS.
How does the Rs pin (Pin 8) configure operating modes in the PCA82C250T/YM,115?
The Rs pin on PCA82C250T/YM,115 selects three distinct modes: grounding Rs enables High-speed mode; connecting a resistor (e.g., 47 kΩ) to ground enables Slope-control mode for RFI reduction; applying >0.75×VCC places PCA82C250T/YM,115 into Standby mode (≤170 µA). These configurations are defined in Table 5 and validated in functional description Section 8.
Is the PCA82C250T/YM,115 qualified for automotive under-hood applications?
Yes, the PCA82C250T/YM,115 is qualified for automotive use with an ambient temperature range of −40 °C to +125 °C and thermal protection activating at ~160 °C junction temperature. Its bus pins tolerate −8 V to +18 V and survive ISO 7637-2 transients - meeting requirements for under-hood placement in ECUs and transmission control units per NXP's automotive qualification statement.
Does the PCA82C250T/YM,115 include built-in protection against bus short-circuits?
Yes, the PCA82C250T/YM,115 includes short-circuit protection to battery and ground on both CANH and CANL outputs, as stated in Features and Benefits and detailed in Section 8. Transmitter current limiting and thermal foldback prevent destruction during sustained shorts - a critical feature validated in automotive fault injection testing.
What is the purpose of the Vref pin (Pin 5) on the PCA82C250T/YM,115?
The Vref pin on PCA82C250T/YM,115 outputs a stable 0.5×VCC reference voltage (±10%), usable for external bus monitoring circuits, termination voltage sensing, or comparator biasing. Its specification - 0.45VCC to 0.55VCC at ±50 µA load - is documented in Table 8 (Characteristics) and supports diagnostic functions in safety-critical CAN networks.
