Product details
Overview
5962-9563301QPA from Texas Instruments is a military-grade dual peripheral OR driver IC in an 8-pin CDIP package, characterized for –55°C to 125°C operation. It features TTL-compatible diode-clamped inputs, open-collector outputs rated up to 30 V and 300 mA per channel, and latch-up immunity at 20 V after conducting full-rated current - used in high-reliability aerospace power interface circuits.
For engineers reviewing the 5962-9563301QPA datasheet, 5962-9563301QPA pinout, 5962-9563301QPA application, or 5962-9563301QPA equivalent, this page delivers verified electrical specs, military temperature validation, CDIP package details, functional mode tables, and direct alternatives for high-current logic-level translation in avionics and defense systems.
Technical Context
The 5962-9563301QPA implements dual-channel positive-logic OR gates (Y = A + B) with internally connected gate outputs driving NPN output transistors. Each channel operates as a high-side switch with open-collector output, supporting sink currents up to 300 mA under 5 V supply while maintaining VOH ≥ VS – 6.5 V at 20 V load voltage.
It uses diode-clamped TTL inputs with VIH ≥ 2 V and VIL ≤ 0.8 V, ensuring compatibility with legacy 5 V logic families. The device avoids latch-up even when subjected to 20 V off-state output stress after conducting rated current - a key reliability feature validated across the full military temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual positive-logic OR gate (Y = A + B); enables independent high-current switching per channel based on any input high condition. |
| Output Current Rating | 300 mA continuous per channel - supports direct drive of lamps, relays, and LEDs without external buffers. |
| Output Voltage Range | Up to 30 V off-state - allows interfacing with 24 V industrial or avionics loads while sinking current to GND. |
| Supply Voltage | 4.5 V to 5.5 V - tightly regulated 5 V operation ensures compatibility with MIL-STD-704A power buses. |
| Operating Temperature | –55°C to 125°C - fully characterized for extended-range deployment in airborne and spaceborne environments. |
| Propagation Delay | 18 ns typical (tPLH/tPHL @ 5 V, 25°C) - enables use in high-speed control loops requiring sub-25 ns timing resolution. |
| Latch-Up Immunity | No latch-up at 20 V after conducting 300 mA - eliminates risk of destructive failure during transient overvoltage events. |
Pinout & Package
5962-9563301QPA is housed in an 8-pin Ceramic Dual In-line Package (CDIP), JG package type, with nominal body size 9.60 mm × 6.67 mm and through-hole mounting. Pin 4 is GND; Pin 8 is VCC; Pins 1, 2, 5, 6, and 7 are active signal terminals; Pins 3 and 7 serve as outputs (1Y, 2Y); all unused pins are unconnected (NC).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Channel 1 logic input A | TTL-compatible input; must be driven to ≥2 V (high) or ≤0.8 V (low); floating state prohibited. |
| 1B | Channel 1 logic input B | Second OR input for Channel 1; tied high/low if unused to prevent undefined output state. |
| 1Y | Channel 1 open-collector output | Sinks current to GND when either 1A or 1B is high; requires external pull-up to load voltage (up to 30 V). |
| GND | Ground reference | Common return path for logic inputs, supply, and output current; must be low-impedance for noise immunity. |
| VCC | Positive supply | 5 V ±0.5 V supply; bypassed with 0.1 µF capacitor near pin to suppress switching transients. |
| 2A | Channel 2 logic input A | Independent OR input for second channel; electrically isolated from Channel 1 except shared VCC/GND. |
| 2B | Channel 2 logic input B | Second OR input for Channel 2; same voltage thresholds and drive requirements as 1A/1B. |
| 2Y | Channel 2 open-collector output | Functionally identical to 1Y; enables dual-load control with separate logic inputs and shared supply rail. |
Key Features
| Feature | Design Value |
|---|---|
| 300 mA per channel sink capability | Eliminates need for discrete transistor stages when driving solenoids, incandescent lamps, or relay coils in MIL-SPEC systems. |
| 30 V output voltage rating | Supports direct interface with 24 V DC aircraft bus systems without level-shifting components. |
| No latch-up at 20 V post-conduction | Ensures fault tolerance during load dump or back-EMF events in motor-control or actuator applications. |
| TTL-compatible diode-clamped inputs | Accepts standard 5 V logic signals without external biasing; clamping diodes protect against input overvoltage. |
| Military temperature characterization | Validated performance across –55°C to 125°C enables use in unheated avionics bays and engine-mounted controllers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual OR driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN55453BJG | Same CDIP-8 package, identical pinout, identical OR logic function, and identical –55°C to 125°C rating; differs only in part numbering convention (non-5962 prefix). | No functional difference; used in non-military procurement channels where 5962-series qualification is not required. | Select SN55453BJG for commercial/mixed-sourcing programs needing identical performance without MIL-PRF-38535 screening. |
| JM38510/12903BPA | Also CDIP-8, –55°C to 125°C, OR function; manufactured under MIL-PRF-38535 Class B with full radiation hardness assurance (not specified for 5962-9563301QPA). | Required for spaceflight or nuclear-hardened systems where total ionizing dose (TID) > 100 krad(Si) is mandated. | Choose JM38510/12903BPA when radiation tolerance beyond standard 5962 qualification is required - otherwise 5962-9563301QPA suffices. |
Compared with SN55453BJG, 5962-9563301QPA carries full 5962-series QML certification and traceable lot documentation; compared with JM38510/12903BPA, it lacks radiation hardness testing but offers lower cost and faster lead times for non-space defense applications.

FAQ
What logic function does the 5962-9563301QPA implement?
The 5962-9563301QPA implements a dual positive-logic OR gate (Y = A + B) per channel. When either input A or B is high (≥2 V), the corresponding open-collector output pulls low to GND. This behavior is confirmed in Table 3 of the SLRS021D datasheet and applies identically to both channels of the 5962-9563301QPA.
Is the 5962-9563301QPA pin-compatible with other SN5545xB variants?
Yes - the 5962-9563301QPA shares identical CDIP-8 (JG) pinout with all SN5545xB devices including SN55451BJG, SN55452BJG, and SN55454BJG. Pin assignments for 1A, 1B, 1Y, GND, VCC, 2A, 2B, and 2Y are standardized across the family, enabling PCB reuse when changing logic functions.
What is the maximum safe load voltage for the 5962-9563301QPA outputs?
The 5962-9563301QPA outputs are rated for up to 30 V off-state voltage (VO), as specified in Absolute Maximum Ratings. In practice, it reliably switches 24 V DC loads such as aircraft lamps and solenoids, with VOH ≥ VS – 6.5 V measured at 20 V load voltage - confirming safe operation within 28 V MIL-STD-704A limits.
Does the 5962-9563301QPA require external pull-up resistors on its outputs?
Yes - the 5962-9563301QPA has open-collector outputs and requires external pull-up resistors to the load supply rail (up to 30 V). Typical values range from 1 kΩ to 10 kΩ depending on rise time and power requirements; the datasheet Figure 18 shows a 65 Ω pull-up for high-speed 24 V lamp driving.
How is the 5962-9563301QPA qualified for military use?
The 5962-9563301QPA is manufactured to MIL-PRF-38535 requirements and screened to QML Class V standards, including extended temperature cycling (–55°C to 125°C), hermeticity testing, and lot traceability. Its qualification is documented in the 5962-9563301QPA orderable addendum and TI's QML listing for SN55453B devices.
