Product details
Overview
5962-9685101QRA from Texas Instruments is a military-grade octal buffer/driver with 3-state inverted 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, delivers ±8 mA output drive, supports –55°C to +125°C operation, and features dual active-low 3-state enable inputs (OE1, OE2) for channel-group control.
For engineers reviewing the 5962-9685101QRA datasheet, 5962-9685101QRA pinout, 5962-9685101QRA application, or 5962-9685101QRA equivalent, key selection criteria include its CDIP-J20 package, MIL-PRF-38535 qualification, TTL-compatible inputs, latch-up immunity (>250 mA), and guaranteed propagation delay ≤7.5 ns (CL = 15 pF).
Technical Context
This device implements eight independent inverting buffer channels, each with dual-input AND-gated 3-state control (OE1 and OE2). Outputs enter high-impedance state when either OE input is high, enabling flexible bus arbitration across two logical groups.
It uses AHCT logic family silicon, ensuring TTL-voltage compatibility (VIH = 2 V min, VIL = 0.8 V max) while maintaining CMOS power efficiency. Absolute maximum ratings include VCC up to 7 V and VI/VO range of –0.5 V to VCC + 0.5 V, supporting robust interface margining.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures stable operation across industrial and military power rails with 10% tolerance. |
| Output Drive | ±8 mA - Sufficient to drive standard TTL loads or 50-pF transmission lines without external buffering. |
| Propagation Delay | ≤7.5 ns at CL = 15 pF - Enables reliable timing in 100-MHz bus environments with margin. |
| Operating Temperature | –55°C to +125°C - Qualified for extended-range military and aerospace applications per MIL-PRF-38535. |
| Input Compatibility | TTL-level (VIH ≥ 2 V, VIL ≤ 0.8 V) - Directly interfaces legacy TTL logic without level-shifting circuitry. |
| ESD Protection | 2000-V HBM, 200-V MM, 1000-V CDM - Meets JESD22 requirements for handling and board assembly robustness. |
| Latch-Up Immunity | >250 mA per JESD17 - Prevents destructive latch-up during transient overvoltage events in harsh environments. |
Pinout & Package
5962-9685101QRA is housed in a 20-pin Ceramic Dual In-line Package (CDIP) with J outline per JEDEC MO-001AB, 0.300-inch wide body, and through-hole mounting. Pin 1 is located at top-left corner with notch or dot marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8 | A1–A8 Inputs | Inverting data inputs; each controls corresponding Y output polarity and state when enabled. |
| 9 | GND | Ground reference for all internal circuitry and output drivers; must be low-impedance connection. |
| 10 | VCC | Positive supply rail (4.5–5.5 V); decoupling capacitor required within 1 cm for noise suppression. |
| 11, 19 | OE1, OE2 | Active-low 3-state enables; either high forces associated Y outputs into high-Z; both low enable inversion. |
| 12, 13, 14, 15, 16, 17, 18, 20 | Y1–Y8 Outputs | Inverted buffered outputs; high-impedance when OE1 or OE2 is high; otherwise Y = NOT(A). |
Key Features
| Feature | Design Value |
|---|---|
| TTL-Compatible Inputs | Accepts standard TTL logic thresholds (VIH ≥ 2 V, VIL ≤ 0.8 V), eliminating need for level translators in mixed-logic systems. |
| Dual 3-State Control | Independent OE1/OE2 pins allow partitioning of the eight outputs into two controllable groups for selective bus isolation. |
| MIL-PRF-38535 Qualified | Fully screened to Class Q or V per MIL-PRF-38535, including radiation hardness assurance and lot traceability for defense programs. |
| High Noise Immunity | Guaranteed 0.4 V noise margin at VCC = 4.5 V, reducing susceptibility to ground bounce and crosstalk in dense PCB layouts. |
| Bus-Friendly Layout | Inputs on one side (pins 1–8), outputs on opposite side (pins 12–20), simplifying layer routing and minimizing signal crossing on PCBs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal buffer/driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54AHCT540J | Identical electrical specs and CDIP-J20 package; same MIL-PRF-38535 qualification level but different lot traceability and screening documentation. | Approved for identical defense programs but may require separate qualification paperwork per contract clause. | Select SNJ54AHCT540J only if procurement mandates TI's legacy military part numbering rather than 5962-series prefix. |
| 5962-9685101QRB | Same die and functionality; differs only in screening grade (Class B vs Class Q/V) and test coverage per MIL-PRF-38535. | Suitable for non-safety-critical subsystems where full Class Q/V burn-in and radiation testing are not required. | Choose 5962-9685101QRB for cost-sensitive military platforms where reduced test rigor is contractually acceptable. |
Compared with 5962-9685101QRA, SNJ54AHCT540J offers identical performance but diverges in documentation lineage, while 5962-9685101QRB trades full Class Q/V screening for lower acquisition cost-both retain pinout, timing, and DC specs without layout changes.

FAQ
What is the operating temperature range for 5962-9685101QRA?
The 5962-9685101QRA is rated for operation from –55°C to +125°C, fully qualified per MIL-PRF-38535 for use in extreme-environment military and aerospace applications. This range is verified across all electrical parameters in the datasheet's recommended operating conditions table and confirmed by thermal characterization in the SCLS268M revision M document.
Does 5962-9685101QRA support TTL-level input signals?
Yes, 5962-9685101QRA features TTL-voltage compatible inputs with VIH minimum of 2.0 V and VIL maximum of 0.8 V at VCC = 4.5 V, allowing direct connection to legacy TTL logic families without level-shifting components. This is explicitly stated in the FEATURES section and verified in the RECOMMENDED OPERATING CONDITIONS table.
What package type is used for 5962-9685101QRA?
5962-9685101QRA uses a 20-pin Ceramic Dual In-line Package (CDIP) with J outline per JEDEC MO-001AB, 0.300-inch body width, and through-hole leads. This is confirmed in the PACKAGE OPTION ADDENDUM, where "Package Type" is listed as CDIP and "Package Drawing" as J for orderable device 5962-9685101QRA.
How does the 3-state enable logic work on 5962-9685101QRA?
The 5962-9685101QRA uses two active-low enable inputs (OE1 and OE2) feeding an AND gate per channel group. If either OE1 or OE2 is high, all corresponding outputs go to high-impedance state. Only when both OE1 and OE2 are low do the outputs actively drive inverted logic levels. This is defined in the FUNCTION TABLE and LOGIC DIAGRAM sections of the datasheet.
Is 5962-9685101QRA pin-compatible with commercial SN74AHCT540 variants?
No-5962-9685101QRA uses the CDIP-J20 package, whereas commercial SN74AHCT540 variants use SSOP (DB), TVSOP (DGV), SOIC (DW), PDIP (N), SO (NS), or TSSOP (PW) packages. While logic function and pin functions match, physical pin spacing, lead count, and mounting method differ; PCB layout must be redesigned for CDIP-J20.
