Product details
Overview
DS26LV32AW-QML from Texas Instruments is a radiation-hardened, high-speed quad differential line receiver compliant with TIA/EIA-422-B and ITU-T V.11 standards. It operates from 3.0V to 3.6V, supports −55°C to +125°C temperature range, delivers ±200mV differential input sensitivity over −0.5V to +5.5V common-mode range, and features TRI-STATE enables for active-high/active-low control in space-grade RS-422 data links.
For engineers reviewing the DS26LV32AW-QML datasheet, DS26LV32AW-QML pinout, DS26LV32AW-QML application, or DS26LV32AW-QML equivalent, key selection criteria include its QML-qualified CFP-16 package, failsafe open-input behavior, TTL/LVCMOS-compatible outputs, low 30 mW typical power consumption, and guaranteed operation across extended military temperature extremes.
Technical Context
The DS26LV32AW-QML implements four independent CMOS receivers with fully differential inputs and single-ended TTL/LVCMOS-compatible outputs. Its receiver architecture supports interoperability with legacy 5V RS-422 networks while operating at 3.3V supply, enabled by extended common-mode range (−0.5V to +5.5V) and ±200mV minimum detectable differential voltage.
TRI-STATE enable logic is shared across all four channels and supports both EN (active-high) and EN̅ (active-low) inputs. The device includes failsafe biasing that forces RO outputs high when inputs are open, and meets MIL-STD-883 Class B screening per Group A test plan including static/dynamic/functional testing at −55°C, +25°C, and +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - Enables direct integration into 3.3V space avionics buses without level-shifting. |
| Differential Input Sensitivity | ±200mV - Guarantees reliable signal detection under low-amplitude noise-prone RS-422 conditions. |
| Common-Mode Range | −0.5V to +5.5V - Supports interoperability with 5V transmitters and ground-shifted systems. |
| Propagation Delay | 6.0–45ns - Ensures sub-50ns timing margin for high-speed serial links up to ~20 Mbps. |
| Operating Temperature | −55°C to +125°C - Qualified for use in satellite payload electronics and launch vehicle control systems. |
| Power Dissipation | 30 mW typical - Reduces thermal load in sealed, conduction-cooled spacecraft modules. |
| Input Resistance | 5.0 kΩ - Matches standard RS-422 termination impedance for minimal signal reflection. |
Pinout & Package
DS26LV32AW-QML is housed in a hermetically sealed Ceramic Flatpack (CFP) package designated NAD0016A, with 16 leads and lead finish specified as "Call TI" per TI packaging addendum. This QML-qualified package meets MIL-PRF-38535 requirements for space-level reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 7 | Differential Input A−, B−, C−, D− | Inverting inputs for each of four receiver channels; accept differential signals within −0.5V to +5.5V common-mode range. |
| 2, 4, 6, 8 | Differential Input A+, B+, C+, D+ | Non-inverting inputs for each channel; paired with corresponding inverting inputs for full-duplex RS-422 reception. |
| 9, 11, 13, 15 | Receiver Output ROA, ROB, ROC, ROD | TTL/LVCMOS-compatible outputs; drive high when inputs are open (failsafe). |
| 10, 12 | EN, EN̅ | Shared active-high and active-low enable controls; simultaneously disable all four outputs into high-impedance state. |
| 14 | VCC | Positive supply rail (3.0V–3.6V); decoupling required per MIL-STD-1547 for EMI suppression. |
| 16 | GND | Signal reference plane; must be connected to system ground with low-inductance path per space PCB layout rules. |
Key Features
| Feature | Design Value |
|---|---|
| Failsafe open-input detection | RO outputs default high when inputs are unconnected - prevents undefined logic states in unterminated or faulted RS-422 lines. |
| QML-38535 Class B qualification | Screened per MIL-STD-883 Group A test plan across −55°C/+25°C/+125°C - certified for flight-critical subsystems. |
| Interoperability with 5V RS-422 | Operates at 3.3V supply while accepting 5V transmitter outputs via extended common-mode range - eliminates need for external level shifters. |
| Low skew performance | ≤6.0ns channel-to-channel skew (tSK2) - maintains timing alignment across multi-channel telemetry receivers. |
| TRI-STATE dual-enable interface | Shared EN/EN̅ pins allow flexible system-level control using either active-high or active-low logic families without glue logic. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad differential receiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS26C32AT | 5V-only supply (4.75–5.25V); identical pinout and functional behavior but lacks extended common-mode range and QML qualification. | Restricted to non-radiation environments; unsuitable for spaceflight due to absence of MIL-STD-883 screening and lower voltage tolerance. | Select DS26C32AT only for terrestrial industrial RS-422 systems where radiation hardness and wide common-mode range are unnecessary. |
| SN65LVD16 | 3.3V supply, 16-pin SOIC package; no QML qualification; common-mode range limited to −1V to +3.4V; no failsafe open-input feature. | Designed for commercial telecom infrastructure; not rated for extended temperature or radiation exposure; requires external bias resistors for open-input handling. | Choose SN65LVD16 for cost-sensitive ground-based equipment where hermetic packaging and space qualification are not required. |
Compared with DS26C32AT and SN65LVD16, DS26LV32AW-QML uniquely combines QML-38535 Class B qualification, −55°C to +125°C operation, failsafe open-input behavior, and −0.5V to +5.5V common-mode support-making it the sole option qualified for flight-critical RS-422 receiver roles in radiation-intensive environments.

FAQ
What is the qualified temperature range for DS26LV32AW-QML?
The DS26LV32AW-QML is fully qualified for operation from −55°C to +125°C per MIL-STD-883 Group A testing across all subgroups. This range is verified through static, dynamic, functional, and switching tests at each extreme temperature point, ensuring reliability in orbital thermal cycling and launch-phase environmental stress. DS26LV32AW-QML maintains specified propagation delay, input sensitivity, and output drive strength across this full range.
Does DS26LV32AW-QML support failsafe operation when inputs are open?
Yes, DS26LV32AW-QML includes an integrated failsafe feature that forces all receiver outputs (ROA–ROD) high when differential inputs are left unconnected or unterminated. This behavior is inherent to the internal bias network and does not require external resistors. DS26LV32AW-QML guarantees this function across its entire operating temperature and supply voltage range, preventing undefined logic states in faulted or unpowered RS-422 links.
Is DS26LV32AW-QML pin-compatible with DS26C32AT?
Yes, DS26LV32AW-QML is pin-compatible with DS26C32AT in the CFP-16 (NAD) package, sharing identical pin assignments for inputs, outputs, enables, VCC, and GND. However, DS26LV32AW-QML operates at 3.0–3.6V and adds extended common-mode range and QML qualification-while DS26C32AT requires 5V and lacks radiation hardening. Electrical substitution requires voltage domain verification.
What package type and marking does DS26LV32AW-QML use?
DS26LV32AW-QML uses the NAD0016A Ceramic Flatpack (CFP) package with 16 leads and is marked "DS26LV32AW-QML Q" on the top surface. Per TI's packaging addendum, it ships in tubes of 19 units and carries QML-38535 Class B qualification. The package is hermetically sealed and rated for space-level reliability with no moisture sensitivity level (MSL) rating due to its ceramic construction.
What are the enable logic configurations supported by DS26LV32AW-QML?
DS26LV32AW-QML provides dual-enable inputs: EN (pin 10) is active-high and EN̅ (pin 12) is active-low. Both control all four receiver outputs simultaneously. Driving EN high (≥2.0V) or EN̅ low (≤0.8V) activates the outputs; driving EN low or EN̅ high places all RO outputs in high-impedance TRI-STATE. This dual-enable architecture allows seamless integration with either positive- or negative-logic control systems without additional inverters.
