Product details
Overview
JM38510/12905BPA from Texas Instruments is a military-grade dual peripheral NOR driver IC designed for high-current, high-speed switching in TTL-based systems. It delivers 300 mA per channel, supports up to 30 V output voltage, operates across –55°C to 125°C, and features open-collector outputs with diode-clamped TTL-compatible inputs - used in ruggedized lamp, LED, and line driving applications.
For engineers reviewing the JM38510/12905BPA datasheet, JM38510/12905BPA pinout, JM38510/12905BPA application, or JM38510/12905BPA equivalent, key selection criteria include its military temperature range, guaranteed latch-up immunity at 20 V after 300 mA conduction, dual-channel NOR logic function, and CDIP-8 package compatibility with legacy aerospace and defense PCB layouts.
Technical Context
The JM38510/12905BPA implements two independent NOR gates whose outputs drive NPN transistor switches with open-collector configuration. Each channel accepts TTL-level inputs (VIH ≥ 2 V, VIL ≤ 0.8 V) and sinks up to 300 mA continuously while maintaining VOL ≤ 0.8 V at that load under military temperature extremes.
Its internal architecture includes input diode clamping for transient protection and base-emitter resistors optimized for fast turn-off (tPHL ≤ 35 ns typical at 200 mA). The device avoids latch-up even when subjected to 20 V off-state output stress - a critical reliability feature for high-voltage peripheral interfacing in avionics and ground vehicle control systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual NOR gate with integrated NPN output transistors - enables active-low drive of lamps, relays, or LEDs without external inversion. |
| Output Current | 300 mA continuous per channel - sufficient to directly drive incandescent lamps, solenoids, or multiple parallel LEDs. |
| Output Voltage Range | Up to 30 V off-state - allows direct interface with 24 V industrial buses or automotive battery-supplied loads. |
| Operating Temperature | –55°C to +125°C - qualified for MIL-PRF-38535 Class B applications in harsh-environment platforms. |
| Propagation Delay | tPLH/tPHL ≤ 35 ns typical at 200 mA - supports high-speed digital control of peripherals without timing bottlenecks. |
| Input Compatibility | TTL-diode-clamped inputs - eliminates need for external pull-ups or level shifters when driven by standard 5 V logic. |
| Supply Voltage | VCC = 4.5 V to 5.5 V - tightly regulated 5 V rail required; bypass capacitor mandatory per layout guidelines. |
Pinout & Package
Package: 8-pin Ceramic Dual In-line Package (CDIP), body size 9.60 mm × 6.67 mm, hermetically sealed for high-reliability military use.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Channel 1 NOR Input A | Active-high TTL input; must be tied to GND or VCC if unused to prevent floating logic state. |
| 1B | Channel 1 NOR Input B | Active-high TTL input; both 1A and 1B must be low for 1Y to activate (pull low). |
| 1Y | Channel 1 Open-Collector Output | Sinks current to GND when enabled; requires external pull-up to load supply (e.g., 24 V). |
| GND | Ground Reference | Common return path for logic and output currents; must be low-inductance connection in high-speed layouts. |
| VCC | Positive Supply | 5 V ±0.5 V logic supply; bypassed with 0.1 µF ceramic capacitor near pin per TI layout guidance. |
| 2A | Channel 2 NOR Input A | Independent second NOR input; electrically isolated from Channel 1 except shared VCC/GND. |
| 2B | Channel 2 NOR Input B | Second NOR input; identical electrical behavior to 1A/1B. |
| 2Y | Channel 2 Open-Collector Output | Functionally identical to 1Y; enables dual-load control from single 5 V logic source. |
Key Features
| Feature | Design Value |
|---|---|
| No latch-up at 20 V | Guaranteed immunity to destructive latch-up when 20 V is applied to outputs during off-state - essential for fault-tolerant 24 V system design. |
| High-speed switching | 35 ns max propagation delay enables real-time control of fast-acting solenoids or PWM-driven lamps without added timing margin. |
| Open-collector flexibility | Allows output pull-up to any voltage ≤30 V - supports mixed-voltage systems where logic is 5 V but loads are 12 V or 24 V. |
| TTL-compatible inputs | Diode-clamped inputs accept standard 5 V TTL logic levels without external biasing - reduces BOM count and board space. |
| Military temperature range | Validated operation from –55°C to +125°C - meets MIL-STD-883 requirements for deployment in airborne, space, and armored vehicle electronics. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN55454BJG | Same die, identical electrical specs, CDIP-8 package - differs only in MIL-PRF-38535 screening level and marking format. | No functional difference; SN55454BJG is commercial-military hybrid screened, while JM38510/12905BPA is full Class B qualified. | Select JM38510/12905BPA when full MIL-PRF-38535 Class B conformance (including burn-in and lot acceptance testing) is contractually required. |

FAQ
What logic function does the JM38510/12905BPA implement?
The JM38510/12905BPA implements two independent NOR gates, each driving an open-collector NPN output transistor. When both inputs (e.g., 1A and 1B) are low, the corresponding output (1Y) pulls low to sink current; all other input combinations leave the output in high-impedance state. This behavior is confirmed in Table 4 of the SLRS021D datasheet and applies identically to JM38510/12905BPA as a member of the SN5545xB family.
Is the JM38510/12905BPA pin-compatible with commercial SN7545xB devices?
No - while JM38510/12905BPA shares identical pinout and logic function with SN75454B, it is packaged in CDIP-8 (JG) and rated for –55°C to +125°C, whereas SN75454B is offered in SOIC, PDIP, or SO packages with 0°C to +70°C rating. Physical pin compatibility exists only with other JG-package variants like SN55454BJG or 7704902PA.
What is the maximum continuous output current per channel for JM38510/12905BPA?
The JM38510/12905BPA is characterized for 300 mA continuous collector current per channel under recommended operating conditions. This value is specified in Section 7.1 (Absolute Maximum Ratings) and validated across the full –55°C to +125°C temperature range, with derating applied above +25°C ambient per dissipation ratings in Section 7.6.
Does JM38510/12905BPA require external pull-up resistors on its outputs?
Yes - the JM38510/12905BPA features open-collector outputs (1Y and 2Y), which can only sink current. An external pull-up resistor (or active pull-up circuit) referenced to the load supply voltage (up to 30 V) is mandatory to establish a defined high state. Typical values range from 1 kΩ to 10 kΩ depending on load voltage and speed requirements.
How is latch-up immunity verified for JM38510/12905BPA?
Latch-up immunity is verified per MIL-STD-883 Method 3014, applying 20 V to the output pins while conducting 300 mA, with no destructive latch-up observed. This test is performed during qualification and is guaranteed for the full military temperature range - a key differentiator from commercial drivers and explicitly documented in the "Features" section of the SLRS021D datasheet for JM38510/12905BPA.
