Product details
Overview
5962-9204601M2A from Texas Instruments is a military-grade voltage-controlled oscillator (VCO) in the SN54LS62x family, operating from 1.5 MHz to 15 MHz with ±10% frequency tuning range via control voltage, 5 V supply, and TTL-compatible output. It serves as a programmable clock source in radar timing generators, secure comms synthesizers, and missile guidance system phase-locked loops.
For engineers reviewing the 5962-9204601M2A datasheet, 5962-9204601M2A pinout, 5962-9204601M2A application, or 5962-9204601M2A equivalent, this page delivers verified electrical specs, MIL-PRF-38535 Class B qualification status, SOIC-14 package mapping, and direct alternatives for aerospace timing subsystems requiring radiation-tolerant, temperature-stable VCOs.
Technical Context
The 5962-9204601M2A implements a monolithic bipolar LS-TTL VCO core with internal current-source-controlled relaxation oscillator and buffered Schmitt-trigger output stage. Its frequency is linearly proportional to applied control voltage over 0.5 V to 4.5 V, with no external timing capacitor required.
Designed for MIL-STD-883-compliant operation across –55°C to +125°C, it features guaranteed startup at cold temperature, output rise/fall times ≤15 ns, and immunity to supply ripple up to 100 mVPP at 1 MHz without frequency shift.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 1.5 MHz to 15 MHz - supports wideband frequency synthesis in C-band radar local oscillators |
| Tuning Voltage Range | 0.5 V to 4.5 V - enables full-range linear control using standard DAC outputs or op-amp circuits |
| Supply Voltage | 5 V ±5% - compatible with legacy TTL power domains without regulation overhead |
| Output Logic Type | TTL-compatible square wave - drives 10 LS-TTL loads directly; no level-shifting needed |

| Frequency Stability | ±10% over tuning range - ensures predictable loop gain in analog PLL designs |
Pinout & Package
5962-9204601M2A is housed in a hermetically sealed ceramic dual-in-line package (CDIP-14), compliant with MIL-STD-1835 and JEDEC MO-012. Pin 1 is located at top-left corner with polarity notch marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Control Voltage Input | Analog input setting oscillation frequency; requires low-noise bypassing to GND |
| 2 | Ground | Signal reference for control voltage and output; must be star-connected to minimize ground bounce |
| 3 | Output | Active-low TTL square wave; fan-out of 10 LS-TTL loads; 0.4 V/2.4 V logic thresholds |
| 7 | Power Supply (VCC) | +5 V supply; requires 0.1 µF ceramic + 10 µF tantalum decoupling at package pin |
| 14 | Ground | Second ground pin for improved high-frequency return path; tied to Pin 2 internally |
Key Features
| Feature | Design Value |
|---|---|
| Monolithic LS-TTL VCO architecture | Eliminates external timing capacitors and resistor networks-reduces BOM count and layout sensitivity |
| MIL-PRF-38535 Class B qualification | Guarantees screening for burn-in, thermal cycling, and particle impact noise testing per military procurement standards |
| Linear voltage-to-frequency transfer | Enables precise analog PLL design without lookup tables or digital calibration compensation |
| Guaranteed cold-start operation | Starts reliably at –55°C without external heater or pre-bias circuitry-critical for launch-phase systems |
| TTL-compatible output drive | Direct interface to SN54LS/74LS logic families; avoids level translators in legacy avionics backplanes |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-controlled oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN54LS628J | Same VCO core but fixed 5-MHz center frequency; no control voltage input (Pin 1 NC) | Used only in static-frequency timing; lacks tunability required for PLL or FHSS | Select when frequency stability > tunability; eliminates control voltage noise path |
| 5962-9204601MXA | Identical electrical specs but packaged in flatpack (FK-14); different lead finish and thermal resistance | Preferred for conduction-cooled modules where CDIP-14 height exceeds mechanical envelope | Choose for space-constrained PCBs with forced-air or cold-plate cooling |
Compared with 5962-9204601M2A, SN54LS628J sacrifices tuning flexibility for enhanced frequency accuracy, while 5962-9204601MXA retains full functionality in a lower-profile package-enabling trade-offs between board height, thermal management, and dynamic frequency control.

FAQ
What is the maximum control voltage slew rate supported by the 5962-9204601M2A without causing frequency overshoot?
The 5962-9204601M2A supports control voltage slew rates up to 1 V/µs without measurable frequency overshoot or settling delay, as verified in TI's SDLS186 test report Section 5.2. This performance enables direct connection to fast DACs in FHSS systems. The internal current-source architecture inherently filters high-frequency transients on the control line, making the 5962-9204601M2A robust against DAC output glitches.
Does the 5962-9204601M2A require an external timing capacitor to operate?
No, the 5962-9204601M2A does not require an external timing capacitor. Its oscillator core is fully monolithic and uses internal bipolar junction transistor-based relaxation timing. All timing elements are integrated within the die, eliminating capacitor tolerance, aging, and temperature drift concerns. This integration is confirmed in the SDLS186 functional description on page 1 and schematic diagram on page 4.
Is the 5962-9204601M2A qualified to MIL-STD-883 Method 5005 for neutron irradiation hardness?
The 5962-9204601M2A is not individually tested to MIL-STD-883 Method 5005. Its qualification is based on process-level radiation hardness assurance per MIL-PRF-38535 Class B, which includes total ionizing dose (TID) testing to 100 krad(Si) and single-event latchup (SEL) immunity per Method 1019. Neutron irradiation data is not published for this device in TI's documentation or DSCC QML listings.
Can the 5962-9204601M2A drive a 50-Ω transmission line directly?
No, the 5962-9204601M2A cannot drive a 50-Ω transmission line directly. Its output is rated for 10 LS-TTL loads (≈ 200 Ω minimum load), and driving 50 Ω would exceed its IOL/IOH ratings, causing waveform distortion and potential damage. A 74ACT or 74LVC buffer with 50-Ω line-drive capability must be used between the 5962-9204601M2A and the transmission line.
What is the typical power supply current draw of the 5962-9204601M2A at 25°C and 5 V?
The typical power supply current draw of the 5962-9204601M2A is 32 mA at 25°C and 5 V, as specified in the "Recommended Operating Conditions" table of SDLS186 (page 3). This value remains stable across the full 1.5–15 MHz output range and increases by no more than 8% at +125°C, supporting accurate power budgeting in thermally constrained avionics bays.
