Product details
Overview
SN65HVS883 from Texas Instruments is an eight-channel, 24-V digital-input serializer for industrial PLC and PC-based I/O modules. It accepts field inputs up to 34 V, provides selectable debounce (0–3 ms), adjustable input current limiting (0.2–5.2 mA), 15-kV HBM ESD protection on field lines, and delivers a regulated 5-V output for external isolators. It serves as the front-end interface between 24-V sensors and low-voltage microcontrollers in isolated digital input systems.
For engineers reviewing the SN65HVS883 datasheet, SN65HVS883 pinout, SN65HVS883 application, or SN65HVS883 equivalent, this page delivers verified technical context, real-world timing and threshold specifications, validated SPI-compatible serial interface behavior, confirmed HTSSOP-28 package mapping, and precise alternative part guidance for industrial automation design.
Technical Context
The SN65HVS883 operates in two synchronized functional modes: Load Mode (LD low) latches parallel field input states IP0–IP7 into an internal 8-bit shift register, while Shift Mode (LD high, CE low) serially clocks data out via SOP on CLK rising/falling edges. Its analog input stage uses a precision current mirror (n = 72) with external RLIM resistor to set per-channel current limit (e.g., 3.6 mA at RLIM = 25 kΩ).
Input validation follows IEC61131-2 Type 1/2/3 thresholds: field-side ON detection at ≥9.4 V (with RIN = 1.2 kΩ), OFF release at ≤8.4 V, providing 1 V hysteresis. The integrated 5-V linear regulator supplies up to 50 mA to external isolators (e.g., ISO72xx), with CHOK monitoring V24 supply status-asserting low after 1 ms if V24 drops below 15 V and returning high after 6 ms when V24 exceeds 18 V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital-input serializer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN65HVS882 | Same 8-channel architecture but fixed 1-ms debounce; no DB0/DB1 pins; lacks CHOK output | Lower-cost option where configurable debounce and supply monitoring are unnecessary | Choose SN65HVS882 only if system design does not require adjustable filtering or V24 status feedback |
| MAX14912 | 8-channel industrial digital input with integrated 10-bit ADC, diagnostics, and 48 V tolerance; SPI interface but no LED drivers | Supports analog-level monitoring and fault reporting beyond binary state capture | Prefer MAX14912 when diagnostic visibility (e.g., open-wire detection, overvoltage flag) is required alongside digital input |
Compared with SN65HVS882 and MAX14912, the SN65HVS883 uniquely balances configurability (debounce, current limit), integrated status signaling (CHOK, REx), and seamless daisy-chaining-making it optimal for cost-sensitive, high-channel-count PLC modules needing field-proven IEC61131-2 compliance without added diagnostics overhead.

FAQ
What is the maximum field input voltage supported by the SN65HVS883?
The SN65HVS883 supports field input voltages up to 34 V on IP0–IP7 pins. This rating is validated per absolute maximum ratings and enables direct interfacing with standard 24-V industrial sensors, including IEC61131-2 Type 1/2/3 switches and EN60947-5-2 proximity devices. Operation above 34 V risks permanent damage, and the device incorporates internal clamping to sustain 15-kV HBM ESD events on these pins.
How do I configure the input current limit for SN65HVS883?
You configure the SN65HVS883 input current limit by connecting an external resistor to the RLIM pin. The relationship is IIP-LIM = 90 V / RLIM; for example, a 25 kΩ resistor sets the limit to 3.6 mA. TI specifies RLIM between 17 kΩ and 500 kΩ, supporting limits from 0.2 mA to 5.2 mA. The resistor must be placed close to the RLIM pin with minimal trace length to ensure accuracy and stability.
Does SN65HVS883 support daisy-chaining, and how many devices can be cascaded?
Yes, the SN65HVS883 supports daisy-chaining via its SIP and SOP pins: connect SOP of one device to SIP of the next. Each SN65HVS883 contributes 8 bits, so N devices yield 8×N serial bits. Timing analysis shows that maximum CLK frequency may decrease with chain length due to cumulative setup/hold margin degradation; TI validates reliable operation for ≥4 devices at reduced clock rates (e.g., 20 MHz for 8-device chains).
What is the function of the CHOK pin on SN65HVS883?
The CHOK (Chip Okay) pin on SN65HVS883 is an open-drain output indicating valid V24 supply voltage. It asserts low if V24 drops below 15 V (with 1-ms debounce) and returns high after 6 ms once V24 exceeds 18 V. This signal enables system-level power supervision without external comparators. CHOK is active during normal operation and ceases only if V24 falls below 10 V, at which point the device shuts down.
Can SN65HVS883 drive LEDs directly, and what current does it provide?
Yes, SN65HVS883 drives LEDs directly through its RE0–RE7 pins, each delivering a constant 3-mA sink current (typical) when configured with RLIM = 25 kΩ. These outputs are designed for status indication and eliminate external current-limiting resistors. Total LED current must remain within the device's thermal limits-TI specifies 2.8–3.5 mA per REx pin under nominal conditions, with derating above 70°C ambient.
