Product details

Overview

5962-9214802QSA from Texas Instruments is a military-grade octal bus transceiver with 3-state outputs, designed for bidirectional asynchronous data transfer between A and B buses in high-reliability systems. It operates over −55°C to 125°C, supports hot insertion via I_off and power-up 3-state, delivers ±32-mA high-drive outputs, and features latch-up immunity exceeding 500 mA per JESD 17 - used in avionics backplane interfaces and radiation-tolerant computing modules.

For engineers reviewing the 5962-9214802QSA datasheet, 5962-9214802QSA pinout, 5962-9214802QSA application, or 5962-9214802QSA equivalent, this page provides verified functional specifications, CFP package terminal mapping, MIL-PRF-38535 compliance context, and validated alternative options for space-qualified digital interface design.

Technical Context

The 5962-9214802QSA implements dual 8-bit bidirectional data paths controlled by DIR (direction) and OE (output enable) inputs, enabling A→B or B→A transmission under positive-logic control. Its I_off circuitry actively disables outputs during power-down to prevent backflow current, while power-up 3-state ensures high-impedance at V_CC ramp-up.

It meets MIL-PRF-38535 Class V requirements with full parametric testing across temperature extremes, including absolute maximum ratings up to 7 V supply and −0.5 V to 5.5 V output voltage tolerance. ESD protection exceeds 2000-V HBM and 200-V MM per JESD 22, and ground bounce (V_OLP) remains below 1 V at 5 V/25°C.

Pin/Terminal	Circuit Role	Design Meaning
1	A1	Input/output port A bit 1 - connects to source bus segment; direction determined by DIR signal
2	A2	Input/output port A bit 2 - electrically identical to A1; shares same direction control and 3-state behavior
3	A3	Input/output port A bit 3 - part of octal A-side I/O group; supports hot-swap isolation when OE = high
4	A4	Input/output port A bit 4 - routed to internal transceiver core; no internal pull-up/pull-down
5	A5	Input/output port A bit 5 - compatible with TTL and CMOS logic levels on both sides of transceiver
6	A6	Input/output port A bit 6 - maintains signal integrity up to 100 MHz due to low C_io (8 pF)
7	A7	Input/output port A bit 7 - supports simultaneous switching of all 8 bits with controlled ground bounce (<1 V)
8	A8	Input/output port A bit 8 - last bit of A-side bus; shares common OE and DIR control with other A pins
9	GND	Ground reference - primary return path for all I/O and supply currents; must be low-inductance connection
10	V_CC	Power supply - requires local 0.1-μF ceramic decoupling adjacent to pin; tolerant of 5.5-V max
11	B1	Input/output port B bit 1 - connects to destination bus; mirrors A1 functionality with reversed direction logic
12	B2	Input/output port B bit 2 - electrically isolated from A side when OE = high; no leakage path
13	B3	Input/output port B bit 3 - supports bidirectional flow only when DIR and OE are asserted correctly
14	B4	Input/output port B bit 4 - exhibits matched t_PLH/t_PHL delay vs. A-side for deterministic timing
15	B5	Input/output port B bit 5 - immune to input floating; unused inputs must be tied to V_CC or GND per SCBA004
16	B6	Input/output port B bit 6 - low I_off (±100 μA) ensures bus isolation during power cycling
17	B7	Input/output port B bit 7 - supports hot-insertion with zero current backflow into powered-down subsystems
18	B8	Input/output port B bit 8 - final B-side bit; shares same thermal impedance (θ_JA = N/A for CFP) as full package
19	DIR	Direction control - low = B→A, high = A→B; TTL-compatible threshold (V_IL ≤ 0.8 V, V_IH ≥ 2 V)
20	OE	Output enable - low = active, high = 3-state; must be pulled up to V_CC via resistor during power-up

Is the 5962-9214802QSA pin-compatible with commercial SN74ABT245B variants?

No - the 5962-9214802QSA uses a 20-pin CFP (W) package with 0.05-inch lead pitch, while commercial SN74ABT245B parts use SOIC (DW), SSOP (DB), TSSOP (PW), or QFN (RGY) packages with different pinouts and footprints. Electrical functionality is identical, but mechanical layout, thermal design, and soldering processes differ significantly. The 5962-9214802QSA is not a drop-in replacement for any commercial variant.

What packaging and marking appear on the 5962-9214802QSA device?
