Product details
Overview
5962-9093901MRA from Texas Instruments is a military-grade octal noninverting buffer/line driver with 3-state outputs, designed for memory address and bus driving in high-reliability systems. It operates from 4.5 V to 5.5 V, features BiCMOS architecture, integrates 33-Ω series output resistors, supports −55°C to +125°C operation, and delivers ±12 mA output drive capability.
For engineers reviewing the 5962-9093901MRA datasheet, 5962-9093901MRA pinout, 5962-9093901MRA application, or 5962-9093901MRA equivalent, this device is evaluated for use in radiation-tolerant avionics, secure communications backplanes, and hardened industrial control I/O expansion where bus isolation, low ICCZ quiescent current, and MIL-PRF-38535 compliance are required.
Technical Context
The 5962-9093901MRA implements two independent 4-bit noninverting buffer sections, each with dedicated active-low output-enable (OE) control. Its BiCMOS design combines bipolar input stages for TTL-compatible thresholds (VIH = 2 V, VIL = 0.8 V) and CMOS output stages with integrated 33-Ω series termination to suppress transmission-line ringing without external components.
Each output transitions between low-impedance drive (±12 mA) and high-impedance state under OE control, enabling bidirectional bus arbitration. Propagation delays are tightly specified (tPLH/tPHL ≤ 6.3 ns at 5 V), and power supply current is minimized in both active (ICCL ≤ 76 mA) and 3-state (ICCZ ≤ 8 mA) modes per device.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures compatibility with legacy 5-V TTL and military logic rails. |
| Operating Temperature | −55°C to +125°C - Qualified per MIL-PRF-38535 for extended environmental survivability. |
| Output Drive | ±12 mA - Sufficient to directly drive terminated 50-Ω transmission lines or standard TTL loads. |
| Output Series Resistor | 33 Ω - Integrated on-die termination eliminates need for external resistors and reduces PCB footprint. |
| Propagation Delay | ≤ 6.3 ns (tPLH, VCC = 5 V) - Enables reliable operation in high-speed address/data multiplexing up to ~80 MHz. |
| Quiescent Current (3-State) | ≤ 8 mA (ICCZ) - Reduces system-level standby power in large-scale bus architectures. |
| Input Thresholds | VIH = 2.0 V, VIL = 0.8 V - Guarantees robust noise margin against TTL-level signal sources. |
Pinout & Package
5962-9093901MRA is housed in a 20-pin Ceramic Dual-In-Line Package (CDIP-J), hermetically sealed for moisture resistance and thermal stability in harsh environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 6, 8, 11, 13, 15, 17 | A1–A4, Y1–Y4 (Group 1) | First 4-bit noninverting buffer path: A inputs → Y outputs when 1OE is low. |
| 3, 5, 7, 9, 12, 14, 16, 18, 19 | A1–A4, Y1–Y4 (Group 2) | Second 4-bit noninverting buffer path: A inputs → Y outputs when 2OE is low. |
| 10 | GND | Power ground reference for all internal circuitry and output drivers. |
| 20 | VCC | Positive supply rail (4.5–5.5 V); must be decoupled locally for noise immunity. |
| 19, 2 | 1OE, 2OE | Active-low enable controls for respective 4-bit groups; tie to VCC via pullup for power-up high-Z safety. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal noninverting 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54BCT2240J | Identical electrical specs and CDIP-J package; same MIL-PRF-38535 Class V qualification level. | No functional difference; identical use cases and reliability profile. | Select when sourcing through TI's legacy military distribution channel with matching lot trace requirements. |

FAQ
What is the absolute maximum supply voltage rating for the 5962-9093901MRA?
The 5962-9093901MRA has an absolute maximum supply voltage (VCC) rating of −0.5 V to 7 V. Operation beyond the recommended 4.5 V to 5.5 V range may cause permanent damage or parametric shift. This rating ensures survivability during transient overvoltage events common in vehicle and aircraft power systems, but sustained operation above 5.5 V is not permitted for 5962-9093901MRA.
Does the 5962-9093901MRA require external pull-up resistors on its OE pins?
Yes-the 5962-9093901MRA OE pins are active-low and must be pulled up to VCC during power-up to ensure outputs remain in high-impedance state until firmware asserts control. TI specifies a minimum pull-up resistor value based on the driver's current-sinking capability; typical values range from 4.7 kΩ to 10 kΩ. This requirement applies identically to both 1OE and 2OE pins on the 5962-9093901MRA.
How does the integrated 33-Ω series resistor in the 5962-9093901MRA improve signal integrity?
The integrated 33-Ω series resistor in the 5962-9093901MRA dampens signal reflections on unterminated or lightly loaded transmission lines, reducing overshoot and undershoot without requiring discrete components. This feature directly lowers PCB component count and layout complexity while maintaining clean edges on memory address or data bus traces up to 15 cm in length-critical for deterministic timing in the 5962-9093901MRA's target applications.
Is the 5962-9093901MRA pin-compatible with commercial-grade SN74BCT2240 variants?
No-the 5962-9093901MRA uses the CDIP-J package with 20 leads arranged per MIL-STD-883, while commercial SN74BCT2240 variants (e.g., SN74BCT2240N, SN74BCT2240DW) use different footprints (PDIP-N, SOIC-DW). Although logic function and pin functions match, physical layout, thermal characteristics, and qualification level differ. Substitution requires board redesign; the 5962-9093901MRA is not a drop-in replacement for SN74BCT2240N.
What is the maximum output current specification for the 5962-9093901MRA in the low state?
The 5962-9093901MRA is rated for a maximum low-state output current (IOL) of 12 mA per pin under recommended operating conditions (VCC = 4.5 V, TA = 25°C). This value is confirmed across the full −55°C to +125°C range per MIL-PRF-38535 testing. Exceeding 12 mA risks violating VOL specifications and may degrade long-term reliability of the 5962-9093901MRA output stage.
