Product details
Overview
SN65HVS880PWP from Texas Instruments is a 24-V, eight-channel digital-input serializer IC for industrial PLC and PC-based I/O modules. It features high-voltage field inputs (up to 30 V), SPI-compatible serial interface, adjustable input current limiting (0.2–5.2 mA), selectable debounce (0/1/3 ms), and integrated 5-V regulator (50 mA output). It interfaces between 24-V sensors and low-voltage controllers via external isolators in EN60947-5-2 and IEC61131-2 Type 1/2/3 compliant systems.
For engineers reviewing the SN65HVS880PWP datasheet, SN65HVS880PWP pinout, SN65HVS880PWP application, or SN65HVS880PWP equivalent, key selection criteria include field input voltage tolerance (30 V), channel count (8), debounce configurability, integrated 5-V supply for isolators, and thermal shutdown at 150°C - all critical for robust industrial digital input design.
Technical Context
The SN65HVS880PWP implements parallel-to-serial conversion using an 8-bit shift register with load (LD), clock (CLK), and clock-enable (CE) control. Input conditioning includes per-channel current limiting (set by RLIM), analog/digital debounce filtering, and hysteresis (1 V field input, 0.9 V internal).
It integrates a linear 5-V regulator (5VOP) with 115 mA current limit and ±2 mV/V line regulation, plus dual fault monitoring: supply voltage monitor (V24 trip at 15 V/18 V with 1–6 ms debounce) and on-die temperature sensor (trip at 150°C, shutdown at 170°C), both feeding a single active-low CHOK health indicator.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input channels | 8 independent high-voltage digital inputs (IP0–IP7), each configurable as current sink up to 5.2 mA |
| Field input voltage range | 0–30 V DC, compliant with IEC61131-2 Type 1/2/3 and EN60947-5-2 proximity switches |
| Debounce time | Selectable via DB0/DB1 pins: 0 ms (bypassed), 1 ms, or 3 ms - prevents false triggering from contact bounce |
| 5-V regulator output | 5.0 V ±5% at 50 mA load; supplies external digital isolators (e.g., ISO72xx) without external LDO |
| Operating temperature | –40°C to +85°C ambient, with overtemperature shutdown at 170°C junction and fault indication at 150°C |
| ESD protection | ±15 kV HBM on field inputs (IPx, V24), enabling direct connection to harsh industrial environments |
| Package | 28-pin HTSSOP (PWP) with PowerPAD™ for enhanced thermal dissipation (θJB = 15°C/W) |
Pinout & Package
SN65HVS880PWP uses a 28-pin HTSSOP (PWP) package with exposed thermal pad (PowerPAD™) for efficient heat transfer to PCB ground plane. Pin 1 is located at top-left corner of package, marked by dot or bevel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IP0–IP7 | Field input channels | High-voltage (0–30 V) current-sink inputs; each requires external series resistor (RIN ≈ 1.2 kΩ) for IEC61131-2 compliance |
| RE0–RE7 | LED return paths | Constant-current (≈3.15 mA) outputs for driving status LEDs; each connects to FGND to complete LED circuit |
| RLIM | Current limit reference | Connects external resistor (17–500 kΩ) to set input current limit: ILIM = 90 V / RLIM (e.g., 25 kΩ → 3.6 mA) |
| V24 | 24-V field supply input | Primary power source for input stage; monitored for undervoltage (15 V) and overvoltage (18 V) with debounced CHOK output |
| 5VOP | Regulated 5-V output | Supplies external isolators (e.g., ISO7241); requires 1 µF + 0.1 µF ceramic decoupling near pin |
| CHOK | Chip-okay indicator | Active-low open-drain output asserting low on supply fault (V24 < 15 V) or overtemperature (>150°C) |
| SIP/SOP | Serial data in/out | SPI-compatible interface: SIP accepts daisy-chained data from upstream device; SOP drives downstream device or controller |
| LD/CLK/CE | Shift register control | LD latches parallel inputs; CLK shifts data on rising edge; CE enables/disables clock propagation |
| DB0/DB1 | Debounce select | Logic inputs selecting debounce time: Open/Open = 3 ms, FGND/Open = 1 ms, Open/FGND = 0 ms (bypass) |
| FGND | Field ground reference | Isolated ground return for field-side circuitry; separate from logic ground to maintain galvanic isolation integrity |
Key Features
| Feature | Design Value |
|---|---|
| Eight-channel high-voltage serialization | Reduces wiring complexity and controller I/O count by consolidating eight 24-V sensor signals into one SPI stream |
| Configurable input current limiting | Enables precise power budgeting per channel via RLIM resistor; supports 0.2–5.2 mA range for diverse sensor types |
| Dual-fault health monitoring | Single CHOK pin reports combined status of supply voltage (V24) and junction temperature - simplifies system-level diagnostics |
| Cascadable architecture | Multiple SN65HVS880PWP devices chain via SIP→SOP, enabling scalable 16-, 24-, or 32-channel input modules without controller changes |
| Integrated 5-V regulator | Eliminates need for external LDO when powering TI's ISO72xx family isolators, reducing BOM count and board space |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital-input serializer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX14912 | 8-channel, 36-V tolerant, integrated 5-V LDO (100 mA), but no built-in debounce; requires external RC filters | Lacks programmable debounce and CHOK health indicator; suited for designs with tight voltage margins but simpler timing requirements | Choose MAX14912 when higher input voltage (36 V) and larger 5-V load current are needed, and debounce can be handled externally. |
| TPL7407L | 7-channel NPN Darlington array (not a serializer); no SPI interface, no 5-V regulator, no fault monitoring | Requires external microcontroller for serialization and diagnostics; limited to low-speed, non-isolated applications | Use TPL7407L only for cost-sensitive, non-isolated, low-channel-count applications where full digital input functionality is not required. |
Compared with MAX14912 and TPL7407L, the SN65HVS880PWP uniquely combines 8-channel serialization, programmable debounce, integrated 5-V supply, and dual-fault CHOK reporting in a single HTSSOP package - making it optimal for space-constrained, high-reliability industrial I/O modules requiring minimal external components.

FAQ
What is the maximum field input voltage supported by the SN65HVS880PWP?
The SN65HVS880PWP supports a maximum field input voltage of 30 V DC on IP0–IP7 and V24 pins, with absolute maximum rating of 35 V. It is designed for 24-V industrial systems and complies with IEC61131-2 Type 1/2/3 and EN60947-5-2 standards. Operation above 30 V risks exceeding recommended conditions and may impact reliability or lifetime.
How does the SN65HVS880PWP implement debounce, and can it be disabled?
The SN65HVS880PWP implements digital debounce via internal logic controlled by DB0 and DB1 pins. Setting DB0 = open and DB1 = FGND configures 0 ms debounce - effectively bypassing the filter. Valid configurations yield 0 ms, 1 ms, or 3 ms delays. This feature prevents false triggers from mechanical switch bounce or EMI-induced transients without requiring external RC networks.
What is the purpose of the RLIM pin on the SN65HVS880PWP, and how is it used?
The RLIM pin on the SN65HVS880PWP sets the per-channel input current limit using an external resistor: ILIM = 90 V / RLIM. For example, a 25 kΩ resistor yields ~3.6 mA. This allows precise adaptation to different sensor types (e.g., 2-wire vs 3-wire proximity switches) and ensures consistent power dissipation and noise immunity across all eight channels of the SN65HVS880PWP.
Does the SN65HVS880PWP provide galvanic isolation, and how is isolation implemented?
The SN65HVS880PWP itself does not provide galvanic isolation - it is a signal conditioner and serializer intended for use with external isolators (e.g., TI ISO7241). Its design separates field-side (IPx, V24, FGND) from logic-side (SIP, SOP, CLK) domains, enabling clean integration of optocouplers or capacitive isolators. The integrated 5VOP output directly powers such isolators, simplifying isolated power architecture for the SN65HVS880PWP-based system.
What fault conditions trigger the CHOK output on the SN65HVS880PWP?
The CHOK output on the SN65HVS880PWP goes low (active-low) when either the supply voltage (V24) drops below 15 V (with 1 ms debounce) or the junction temperature exceeds 150°C. Both conditions are OR'd internally; CHOK remains high only when both are within specification. At 170°C, the device enters thermal shutdown and CHOK becomes high-impedance, pulled low externally by an internal 100 kΩ resistor.
