Product details
Overview
5962-9074901MRA from Texas Instruments is a military-grade octal buffer/driver with 3-state outputs, designed for bus line driving and memory address register buffering in high-reliability systems. It operates from 4.5 V to 5.5 V, features BiCMOS technology, supports –55°C to 125°C operation, and uses a CDIP-J 20-pin hermetic ceramic package.
For engineers reviewing the 5962-9074901MRA datasheet, 5962-9074901MRA pinout, 5962-9074901MRA application, or 5962-9074901MRA equivalent, this device delivers verified 3-state control via dual active-low OE inputs, data-flow-through pinout for PCB layout optimization, and robust DC/AC performance across extended temperature ranges.
Technical Context
The 5962-9074901MRA implements an 8-channel non-inverting buffer architecture with two independent 3-state enable inputs (OE1, OE2), each feeding a 2-input AND gate with active-low logic - ensuring all outputs enter high-impedance state if either OE is high. Its P-N-P input structure reduces DC loading on upstream drivers.
It uses state-of-the-art BiCMOS design to minimize ICCZ (quiescent supply current during 3-state), achieves tPLH/tPHL propagation delays of 1.7–6.3 ns at VCC = 4.5–5.5 V, and maintains output drive capability of 48 mA (SN54BCT541) under recommended operating conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 5.5 V - compatible with standard 5 V TTL/CMOS logic rails and ensures stable operation under voltage variation. |
| Operating Temperature | –55°C to +125°C - qualified per MIL-PRF-38535 for aerospace, defense, and harsh-environment embedded systems. |
| Output Drive (IOL) | 48 mA - sufficient to directly drive terminated bus lines or multiple TTL loads without external amplification. |
| Propagation Delay (tPHL) | Max 8.7 ns at VCC = 4.5 V, CL = 50 pF - enables reliable timing in high-speed address/data path buffering. |
| Input Clamp Current | –18 mA - protects inputs against transient overvoltage events up to –0.5 V, supporting robust system-level ESD resilience. |
| Quiescent Supply Current (ICCZ) | 7 mA max - low power consumption in 3-state mode reduces thermal load in dense backplane or memory module designs. |
| Package Type | CDIP-J (20-pin Ceramic Dual In-line Package) - hermetically sealed, leaded, through-hole mountable for legacy and high-reliability board assemblies. |
Pinout & Package
5962-9074901MRA is housed in a 20-pin CDIP-J package: ceramic dual in-line, 0.3-inch body width, through-hole mounting, hermetic seal, and gold-plated leads compliant with MIL-STD-883.

Key Features
| Feature | Design Value |
|---|---|
| Data-flow-through pinout | Inputs (A1–A8, OE1, OE2) on left side, outputs (Y1–Y8) on right side - simplifies PCB routing, minimizes crosstalk, and eliminates layer jumps in dense layouts. |
| Dual independent 3-state control | Separate OE1 and OE2 inputs allow partitioned bus management - e.g., Y1–Y4 for address, Y5–Y8 for data, each independently tri-stated. |
| P-N-P input structure | Reduces input DC loading by limiting IIH to 20 µA and IIL to –0.6 mA - preserves drive strength of upstream logic in cascaded memory interfaces. |
| BiCMOS process technology | Combines bipolar speed and CMOS low ICCZ - achieves 7 mA max ICCZ while maintaining sub-9 ns propagation delay at full temperature range. |
| MIL-PRF-38535 qualification | Fully tested per QML Class V requirements including screening, burn-in, and lot acceptance testing - certified for flight-critical and strategic systems. |

FAQ
What is the operating temperature range of the 5962-9074901MRA?
The 5962-9074901MRA is rated for –55°C to +125°C operation and fully qualified per MIL-PRF-38535 Class V, making it suitable for deployment in jet engines, space vehicles, and artillery systems where ambient extremes are routine. This range is validated across all electrical parameters including propagation delay, output drive, and ICCZ.
How does the dual OE architecture of the 5962-9074901MRA improve system design?
The 5962-9074901MRA features two independent active-low output enables (OE1, OE2), allowing selective tri-state control of Y1–Y4 and Y5–Y8 groups. This enables flexible bus partitioning - for example, holding memory address lines active while tri-stating data lines during DMA cycles - without requiring additional logic or timing overhead.
Is the 5962-9074901MRA pin-compatible with commercial SN74BCT541 variants?
Yes - the 5962-9074901MRA shares identical pinout, logic function, and DC/AC electrical behavior with SN74BCT541A and SN54BCT541 in CDIP-J packaging. However, only the 5962-9074901MRA carries full MIL-PRF-38535 documentation, screening, and traceability required for defense contracts.
What is the recommended power-up sequence for the 5962-9074901MRA?
To ensure outputs remain in high-impedance during power-up, OE1 and OE2 must be tied to VCC via pull-up resistors. TI specifies minimum resistor values based on driver sink capability; for most applications, 4.7 kΩ to VCC suffices. This prevents bus contention before system controller initialization completes.
Does the 5962-9074901MRA require external decoupling capacitors?
Yes - a 0.1 µF ceramic capacitor must be placed as close as possible to the VCC (pin 11) and GND (pin 10) pins of the 5962-9074901MRA. This mitigates high-frequency supply noise generated during output switching and ensures stable operation across the full –55°C to +125°C range.
