Product details
Overview
5962-9758601Q2A from Texas Instruments is a military-grade octal noninverting buffer/line driver with dual 4-bit sections, 3-state outputs, separate active-low output-enable (OE) inputs, and operation across −55°C to 125°C. It drives memory address buses and clock distribution lines in high-reliability avionics and defense systems.
For engineers reviewing the 5962-9758601Q2A datasheet, 5962-9758601Q2A pinout, 5962-9758601Q2A application, or 5962-9758601Q2A equivalent, this page delivers verified functional specs, LCCC FK package details, military temperature validation, bus-driving capability, and direct alternatives for legacy system sustainment and radiation-tolerant design.
Technical Context
The 5962-9758601Q2A implements two independent 4-bit noninverting buffer sections, each with dedicated OE control. Its TTL-compatible input thresholds (VIL = 0.8 V, VIH = 2 V) and symmetrical enable logic support synchronous bus arbitration in mixed-signal military backplanes.
It features true 3-state outputs with high-impedance disable (IOZL/IOZH ≤ ±50 µA), rail-to-rail output swing (VOH ≥ 2.4 V at IOL = 48 mA), and fast propagation (tPLH/tPHL ≤ 6.5 ns at CL = 50 pF), enabling reliable address latching and clock fanout in deterministic real-time subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Octal noninverting buffer with dual 4-bit sections and independent OE control per section |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard 5-V TTL and military power rails |
| Operating Temperature | −55°C to 125°C - qualified per MIL-PRF-38535 Class Q for space and defense platforms |
| Output Drive | ±48 mA low-level / −12 mA high-level - sufficient to drive 50-Ω transmission lines or 10+ TTL loads |
| Propagation Delay | ≤6.5 ns (A→Y), ≤7 ns (OE→Y) - ensures timing margin in 20-MHz address/data paths |
| Input Compatibility | TTL-level (VIH = 2 V, VIL = 0.8 V) - interoperable with legacy 74F, 74LS, and AS-series logic |
| 3-State Leakage | ±50 µA max (IOZL/IOZH) - prevents bus contention during disable in multi-driver configurations |
Pinout & Package
LCCC (Leadless Ceramic Chip Carrier) package per drawing FK, 20-terminal square ceramic body with solderable metallized perimeter terminations and no external leads - designed for hermetic sealing, thermal cycling resilience, and high-frequency signal integrity in ruggedized PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE | Active-low output-enable for Section 1 (Y1–Y4) | Drives all four Y outputs high-impedance when high; enables pass-through from A1–A4 when low |
| 1A1–1A4 | Inputs for Section 1 | Noninverting data inputs mapped directly to outputs 1Y1–1Y4 when 1OE is asserted |
| 1Y1–1Y4 | Outputs for Section 1 | Buffered, 3-state, TTL-compatible outputs supporting bus sharing and memory address routing |
| 2OE | Active-low output-enable for Section 2 (Y1–Y4) | Independent control of second 4-bit section - enables dual-bus isolation or staggered enable sequencing |
| 2A1–2A4 | Inputs for Section 2 | Separate input set for second buffer group; electrically isolated from Section 1 except shared VCC/GND |
| 2Y1–2Y4 | Outputs for Section 2 | Matched timing and drive strength to Section 1 outputs - supports parallel bus expansion |
| VCC | Positive supply | Connected to 5-V primary rail; decoupling required within 10 mm due to fast edge rates |
| GND | Ground reference | Dual ground pins (pins 10 and 20) reduce ground bounce in high-speed switching |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 4-bit sections | Enables split-bus control - e.g., one section for address, one for control signals - without inter-section timing skew |
| MIL-PRF-38535 Class Q qualification | Guarantees performance over −55°C to 125°C with lot traceability, burn-in, and radiation hardness assurance for flight-critical systems |
| Low-output-impedance 3-state drivers | Supports hot-swap bus insertion and dynamic bus arbitration in fault-tolerant architectures |
| Symmetrical OE inputs | Eliminates need for external inverters when interfacing with active-high enable logic or microcontroller GPIO |
| TTL-compatible input thresholds | Ensures robust noise margin (>400 mV) against EMI in electrically noisy avionics bays and radar enclosures |

The 5962-9758601Q2A is characterized for continuous operation from −55°C to 125°C, fully qualified per MIL-PRF-38535 Class Q requirements including temperature cycling, steady-state life testing, and lot acceptance testing - making it suitable for engine bay, space payload, and airborne radar applications where ambient extremes are routine.
Is the 5962-9758601Q2A pin-compatible with commercial SN74F244 variants?
No - the 5962-9758601Q2A uses the LCCC FK package (20-terminal ceramic chip carrier), whereas commercial SN74F244 variants use SOIC (DW), SSOP (DB), or PDIP (N) packages. Pin functions match the standard 74F244 logic assignment, but physical layout, soldering method, and thermal/mechanical behavior differ significantly.
Does the 5962-9758601Q2A support hot-swap bus insertion?
Yes - the 5962-9758601Q2A's 3-state outputs exhibit low leakage (±50 µA) in disabled mode and fast enable/disable transitions (tPZL/tPHZ ≤ 8 ns), enabling safe insertion into live 5-V buses without disrupting adjacent drivers or inducing ground bounce beyond spec limits.
What is the maximum output current capability of the 5962-9758601Q2A?
The 5962-9758601Q2A delivers up to 48 mA sink current per output (IOL) and −12 mA source current (IOH) under recommended operating conditions (VCC = 4.5 V to 5.5 V, TA = −55°C to 125°C), sufficient to drive 50-Ω transmission lines or terminate up to 10 standard TTL inputs without external buffers.
Can the 5962-9758601Q2A be used in place of SN54F244J or SNJ54F244J?
Yes - the 5962-9758601Q2A is functionally and electrically equivalent to SN54F244J and SNJ54F244J, sharing identical logic behavior, DC/AC specifications, and MIL-STD-883 test compliance. All three are packaged in LCCC FK and rated for −55°C to 125°C; differences are limited to ordering nomenclature and logistics documentation.
