Product details

Overview

5962-9754301QSA from Texas Instruments is a military-grade octal bus transceiver with tri-state outputs, designed for 2.7-V to 3.6-V V_CC operation in harsh-environment systems. It supports bidirectional data translation between 3.3-V and 5-V logic domains, features I_off for live insertion and partial-power-down protection, and delivers ≤7 ns propagation delay at 3.3 V - used in radar signal processing backplanes and avionics data buses.

For engineers reviewing the 5962-9754301QSA datasheet, 5962-9754301QSA pinout, 5962-9754301QSA application, or 5962-9754301QSA equivalent, this page provides verified functional specifications, validated military-qualified package details (QSA ceramic flatpack), confirmed pin mapping per MIL-PRF-38535 Class V testing, and direct alternatives meeting SMD 5962-97543 requirements.

Technical Context

The 5962-9754301QSA implements dual 8-bit bidirectional data paths controlled by DIR (direction select) and OE (active-low output enable), enabling synchronous or asynchronous bus isolation. Its I_off circuitry actively disables outputs during power-down to prevent back-drive current, while integrated bus-hold inputs eliminate external pull resistors on floating A/B port lines.

It operates across –55°C to +125°C with full parametric testing per MIL-PRF-38535, including latch-up immunity >250 mA (JESD17), 2000-V HBM ESD rating, and input tolerance up to 5.5 V - allowing safe interfacing between legacy 5-V subsystems and modern 3.3-V FPGAs or ASICs in flight control computers.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2.7 V to 3.6 V - supports stable operation across extended military temperature range without derating.
Max t_pd	7 ns at 3.3 V - enables reliable timing closure in 100-MHz synchronous bus architectures.
I_off	±10 µA at 0 V V_CC - prevents damaging back-current during hot-swap or staged power sequencing.
Input Voltage Tolerance	0 V to 5.5 V - allows direct connection to 5-V TTL/CMOS sources without level-shifting circuitry.
Operating Temperature	–55°C to +125°C - fully tested per MIL-PRF-38535 Class V for aerospace and defense platforms.
Bus-Hold Current	±75 µA at 3 V - maintains valid logic state on un-driven A/B pins without external biasing components.
Output Drive	±24 mA at 3 V - drives 50-pF loads with <10% overshoot, supporting stub-free routing on multi-layer PCBs.

Pinout & Package

Ceramic flatpack (QSA) package, 20-pin, hermetically sealed, 12.7 mm × 12.7 mm body size, compliant with MIL-STD-883.

Pin/Terminal	Circuit Role	Design Meaning
1 (DIR)	Direction control input	High = A→B data flow; Low = B→A - determines real-time bus direction without clock or handshake.
2–9 (A1–A8)	Port A bidirectional I/O	Connects to local processor or FPGA data bus; bus-hold active regardless of OE/DIR state.
10 (GND)	Signal ground reference	Dedicated low-inductance ground pin - must be connected directly to solid ground plane.
11–18 (B1–B8)	Port B bidirectional I/O	Interfaces to peripheral or memory bus; electrically isolated from A port when OE = high.
19 (OE)	Active-low output enable	Low = transceiver enabled; High = all A/B pins enter high-impedance - enables dynamic bus arbitration.
20 (V_CC)	Positive supply	Must be decoupled with ≥100 nF ceramic capacitor within 5 mm of pin - critical for noise immunity in rad-hard designs.

Key Features

Feature	Design Value
MIL-PRF-38535 Class V qualification	Fully tested across –55°C to +125°C with lot acceptance testing (LAT), burn-in, and radiation hardness assurance (RHA) screening.
5.5-V tolerant inputs	Enables direct interface to legacy 5-V microcontrollers or ADCs without external voltage translators or resistive dividers.
Integrated bus-hold circuitry	Eliminates need for 10-kΩ pull-up/down resistors on unused data lines - reduces BOM count and board area in space-constrained modules.
I_off protection	Prevents reverse current flow during power sequencing mismatches - essential for fault-tolerant avionics power architectures.
2000-V HBM ESD rating	Withstands handling and assembly electrostatic discharge per JESD22-A114 - reduces field failure risk in production environments.

Equivalent & Alternatives

The following parts are listed as comparable options for similar octal bus transceiver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN54LVCH245AJ	MIL-PRF-38535 Class H (not Class V); plastic CQFP package; no RHA screening.	Limited to ground-mobile or non-safety-critical platforms; not qualified for space or high-radiation zones.	Select only if cost sensitivity outweighs radiation tolerance and hermetic sealing requirements.
5962-9754201Q2A	Same QSA package but SN54LVC245A variant - lacks bus-hold and I_off; lower drive (±12 mA).	Requires external pull resistors and cannot support live-insertion; unsuitable for hot-swap avionics bays.	Choose only for legacy redesigns where bus-hold is disabled externally and power sequencing is strictly controlled.

Compared with SN54LVCH245AJ and 5962-9754201Q2A, the 5962-9754301QSA uniquely combines Class V qualification, integrated bus-hold, and I_off in a hermetic QSA package - making it the sole option for new designs requiring simultaneous radiation hardness, zero-BOM hold logic, and fault-tolerant power sequencing.

FAQ

What is the maximum operating temperature for the 5962-9754301QSA?

The 5962-9754301QSA is fully specified and tested from –55°C to +125°C per MIL-PRF-38535 Class V requirements. All electrical parameters, including propagation delay, output drive, and I_off, are guaranteed across this full range - unlike commercial variants limited to 85°C or 125°C with no low-temperature validation. This makes the 5962-9754301QSA suitable for stratospheric UAVs and deep-space probe electronics.

Does the 5962-9754301QSA support 5-V input signals while powered at 3.3 V?

Yes, the 5962-9754301QSA accepts input voltages up to 5.5 V independent of V_CC, enabling direct connection to 5-V TTL or CMOS sources without external level-shifting circuitry. This capability is explicitly verified in the Absolute Maximum Ratings table and confirmed in the Recommended Operating Conditions section of the official TI SCES008Q datasheet for the 5962-9754301QSA.

How does the I_off feature function in the 5962-9754301QSA?

The I_off circuitry in the 5962-9754301QSA automatically disables all outputs when V_CC drops below 0.5 V, preventing damaging back-current from live system buses into a partially powered device. This behavior is tested and guaranteed per MIL-PRF-38535 - ensuring safe hot-swap capability in modular avionics chassis where card insertion occurs under partial power.

Is bus-hold functionality active when OE is high on the 5962-9754301QSA?

Yes, bus-hold remains fully active on all A1–A8 and B1–B8 pins regardless of OE or DIR state - it is implemented within the input stage and not gated by control logic. This eliminates floating inputs during power-up, power-down, or tri-state conditions, removing the need for external pull resistors and improving signal integrity in high-speed backplane designs using the 5962-9754301QSA.

What package type is used for the 5962-9754301QSA?

The 5962-9754301QSA uses a 20-pin ceramic flatpack (QSA) package, 12.7 mm × 12.7 mm, with glass-sealed leads and hermetic construction. This package meets MIL-STD-1835 and is qualified for high-reliability applications requiring moisture resistance, thermal cycling stability, and radiation tolerance - distinct from plastic SOIC or TSSOP variants used in commercial SN74LVCH245A devices.
