Product details
Overview
5962-9557701NXD from Texas Instruments is a military-grade 36-bit noninverting bus transceiver with 3-state outputs, designed for synchronous bidirectional data transfer between high-speed parallel buses. It features quad 9-bit sections, ±32-mA high-drive outputs, bus-hold on all data inputs, and operates across –55°C to 125°C. Used in avionics backplanes and ruggedized military computing systems requiring latch-up immunity >500 mA and ground bounce <0.8 V.
For engineers reviewing the 5962-9557701NXD datasheet, 5962-9557701NXD pinout, 5962-9557701NXD application, or 5962-9557701NXD equivalent, key selection criteria include its QML-38535 qualified PZ package, DIR/OE control architecture, 4.5–5.5-V operation, and guaranteed isolation during power-up/down below 2.1 V.
Technical Context
The 5962-9557701NXD implements four independent 9-bit transceiver sections, each with separate direction (DIR) and output-enable (OE) controls. Its EPIC-IIB BiCMOS process enables low power dissipation while delivering –32-mA IOH and 64-mA IOL drive strength per output.
It integrates active bus-hold circuitry on all A/B port inputs to eliminate external pullup/pulldown resistors, and uses distributed VCC/GND pins to suppress high-speed switching noise. The device enters high-impedance state when VCC is between 0 and 2.1 V, ensuring safe power sequencing.
Key Specifications

| 1OE, 2OE, 3OE, 4OE | Output-enable input (per 9-bit section) | OE = L enables transceiver; OE = H forces all outputs into high-impedance state |
| A1–A9, B1–B9 (×4 groups) | Data I/O terminals | 36 bidirectional data lines grouped as four 9-bit ports; bus-hold enabled on all |
| VCC (pins 13, 26, 41, 50, 62, 75, 89, 100) | Power supply | Distributed VCC pins minimize simultaneous switching noise and IR drop |
| GND (pins 12, 25, 40, 51, 61, 74, 88, 99) | Ground reference | Distributed GND pins provide low-inductance return paths for high-speed switching |
Key Features

| Latch-up immunity >500 mA | Exceeds JEDEC JESD-17 - enables reliable operation in high-noise military platforms |
| Output ground bounce <0.8 V | Measured at VCC = 5 V, TA = 25°C - reduces signal integrity risk in dense PCB layouts |
| Active bus-hold on all data inputs | Eliminates need for 36 external pullup/pulldown resistors - saves board space and BOM cost |
| Distributed VCC/GND pin configuration | Eight VCC and eight GND pins interleaved across package - lowers power delivery impedance |
| High-impedance during power up/down | Automatic Hi-Z when VCC ∈ [0, 2.1 V] - prevents back-driving and bus contention at power transition |

FAQ
What is the full military temperature range supported by the 5962-9557701NXD?
The 5962-9557701NXD is fully characterized and qualified for operation from –55°C to 125°C per MIL-PRF-38535 requirements. This range is verified across all electrical parameters including propagation delay, drive strength, and bus-hold functionality - critical for deployment in jet engine bays, missile canisters, and satellite payload bays where ambient extremes occur.
Does the 5962-9557701NXD require external pullup resistors on its data inputs?
No, the 5962-9557701NXD includes active bus-hold circuitry on all A and B port inputs, providing ±100 µA hold current at VI = 0.8 V or 2.0 V. This eliminates the need for external pullup or pulldown resistors, reducing BOM count, PCB area, and potential signal integrity issues caused by resistor parasitics - a key advantage in compact military modules.
How does the 5962-9557701NXD ensure bus isolation during power-up sequences?
The 5962-9557701NXD automatically enters a high-impedance state whenever VCC is between 0 V and 2.1 V, preventing back-driving or contention on connected buses during power ramp-up or brownout. For guaranteed isolation above 2.1 V, OE must be tied to VCC via a pullup resistor - a design requirement explicitly defined in the 5962-9557701NXD datasheet.
Is the 5962-9557701NXD pin-compatible with commercial variants like SN74ABTH32245PZ?
Yes, the 5962-9557701NXD shares identical pinout, package footprint (100-pin PZ), and electrical interface with SN74ABTH32245PZ. However, it is not a drop-in replacement in certified systems due to differences in qualification scope: only the 5962-9557701NXD carries QML-38535 certification and full military temperature characterization.
What packaging and compliance standards apply to the 5962-9557701NXD?
The 5962-9557701NXD is supplied in a green (RoHS & no Sb/Br), lead-free LQFP package (PZ drawing) with CU NIPDAU finish, rated MSL-3 (260°C, 168 hr). It is qualified per MIL-PRF-38535 Class V for high-reliability military use and conforms to JEDEC MS-026 mechanical standards - documentation includes full DSCC SMD release and traceable lot-level test reports.
