Product details
Overview
5962R0052402VGA from Texas Instruments (formerly National Semiconductor) is a radiation-hardened voltage comparator in an 8-lead TO-99 metal can package, designed for space and high-reliability military systems. It delivers ±3 mV input offset voltage, 200 nA max input bias current, 300 ns collector-output response time, and operates across −55°C to +125°C with supply voltages from ±15 V or single 5 V. It drives TTL/DTL/RTL loads and switches up to 50 V at 50 mA in satellite power sequencing and fault-detection circuits.
For engineers reviewing the 5962R0052402VGA datasheet, 5962R0052402VGA pinout, 5962R0052402VGA application, or 5962R0052402VGA equivalent, key selection criteria include ELDRS-free radiation tolerance (100 krad(Si)), strobe capability, ground-isolated inputs/outputs, wire-ORable open-collector output, and compatibility with legacy LM106/LM710 layouts.
Technical Context
The 5962R0052402VGA implements a bipolar transistor-based differential input stage with active load and Darlington output, enabling wide common-mode input range (±30 V) and rail-to-rail output swing capability. Its strobe pin (Pin 6) allows synchronous enable/disable of comparison, critical for time-gated sensing in pulsed radar and telemetry systems.
Unlike standard comparators, it supports three-terminal load referencing-output can drive loads tied to ground, positive supply, or negative supply-enabling direct interface with relays, lamps, and MOSFET gates without level-shifting circuitry. Offset nulling via Pins 5 and 6 provides precise threshold calibration under thermal stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ±3.0 mV max (ensures accurate threshold detection within 3 mV over full temperature range) |
| Input Bias Current | 100 nA max (minimizes loading on high-impedance sensor sources like radiation monitors) |
| Response Time | 300 ns (supports fast edge detection in pulse-width modulated power control loops) |
| Radiation Tolerance | 100 krad(Si), ELDRS-free (qualified for long-duration low-dose-rate missions such as geostationary satellites) |
| Supply Voltage Range | Single 5 V or dual ±15 V (enables interoperability with both digital logic rails and analog op-amp supplies) |
| Output Drive Capability | 50 V / 50 mA (directly switches solenoids, LED arrays, and discrete power FETs without external drivers) |
| Operating Temperature | −55°C to +125°C (meets MIL-STD-883 Group A testing requirements for extreme-environment avionics) |
Pinout & Package
Package: 8-lead hermetic TO-99 metal can (NS Package Number H08C), case-connected to Pin 4 for EMI shielding and thermal conduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (−) | Differential input node referenced to system ground or floating supply; accepts ±30 V common-mode range |
| 2 | Non-Inverting Input (+) | Differential input node with identical voltage range and leakage specs as Pin 1 |
| 3 | Ground / Reference | Reference terminal for internal biasing; may be isolated from system ground per application need |
| 4 | Case / Shield | Internally connected to metal can; must be tied to chassis ground for EMI suppression and thermal dissipation |
| 5 | Offset Null (Balance) | Adjustment terminal for trimming input offset voltage using external potentiometer |
| 6 | Strobe / Balance | Enables/disables comparator action; when pulled low, forces output high-impedance state |
| 7 | Collector Output | Open-collector NPN output capable of sinking 50 mA; requires external pull-up for logic-level interfacing |
| 8 | Positive Supply (V+) | Primary positive rail connection; supports up to +30 V absolute maximum rating |
Key Features
| Feature | Design Value |
|---|---|
| ELDRS-free radiation hardening | Validated to 100 krad(Si) with no enhanced low-dose-rate sensitivity-certified for deep-space missions |
| Strobe-enabled comparison | Pin 6 allows synchronous gating of comparator function, eliminating false triggers during transient events |
| Wire-ORable open-collector output | Multiple 5962R0052402VGA outputs can share a single pull-up resistor for priority-encoded fault-bus signaling |
| Ground-isolated I/O | Inputs and output operate independently of system ground reference-enables floating-sensor interfaces |
| Legacy LM106/LM710 pin compatibility | Direct drop-in replacement in existing designs without PCB revision or layout changes |

FAQ
What is the radiation hardness specification for 5962R0052402VGA?
The 5962R0052402VGA is qualified to 100 krad(Si) total ionizing dose with ELDRS-free performance, verified per MIL-STD-883 Method 1019 Condition D. This means it exhibits no enhanced low-dose-rate sensitivity and maintains full functionality after prolonged exposure in geosynchronous orbit environments. All electrical parameters-including input offset voltage and response time-remain within datasheet limits post-irradiation.
Can 5962R0052402VGA replace LM106 or LM710 in existing designs?
Yes, the 5962R0052402VGA uses the same 8-pin TO-99 pinout as the LM106 and LM710, making it a direct physical and functional replacement. No PCB modifications are needed. However, designers should verify that strobe (Pin 6) and balance (Pin 5) connections match legacy usage, as unused pins must be shorted or terminated per application notes to prevent oscillation.
What is the maximum load voltage the 5962R0052402VGA output can switch?
The 5962R0052402VGA collector output supports up to 50 V above the negative supply rail, with absolute maximum rating of +30 V on V+ and −30 V on V−. When driving inductive loads like relays, a flyback diode must be placed across the load to clamp inductive kickback and protect the output transistor from breakdown.
Does 5962R0052402VGA support single-supply operation?
Yes, the 5962R0052402VGA operates from a single 5 V supply, with inputs functional down to 0 V and output compatible with TTL/DTL logic families. In single-supply mode, the non-inverting input (Pin 2) serves as the reference threshold, while the inverting input (Pin 1) receives the monitored signal-enabling simple zero-crossing or overvoltage detection without level-shifting circuitry.
How is the strobe function implemented on 5962R0052402VGA?
The strobe function is controlled by Pin 6 (Balance/Strobe). When Pin 6 is pulled low (≤0.8 V), the comparator output enters high-impedance state regardless of input conditions-effectively disabling comparison. When Pin 6 is open or pulled high (≥2.0 V), normal comparator operation resumes. This enables synchronized sampling in time-critical measurement systems such as pulsed radar receivers.
