Overview
The Texas Instruments 5962-9221303MRA is a military-grade, fast CMOS octal buffer and line driver. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an extended temperature range from -55°C to +125°C. The device features true TTL input and output compatibility with typical high-level output voltage of 3.3 V and low-level output voltage of 0.3 V. It provides high drive outputs capable of sourcing -15 mA and sinking 64 mA. The component meets JEDEC standard 18 specifications and complies with MIL-STD-883, Class B requirements.
Feature Summary
- Provides high drive outputs for improved board density in memory and address driver applications
- Features power-off disable capability to permit live insertion operations
- Ensures low input and output leakage current of 1 uA maximum
Applications
- Memory and address drivers
- Clock drivers
- Bus-oriented transmitter/receiver circuits
Procurement Notes
Verify the specific suffix '03MR' against official datasheets to confirm package type and military qualification status. Ensure compliance with MIL-STD-883 Class B requirements is documented for your application. Confirm availability through authorized distributors as this is a specialized military component.
Selection Notes
Select this component when high-speed buffering and strong drive capabilities are required in harsh environments. The true TTL compatibility simplifies interface design with legacy logic families. Consider the power-off disable feature if system reliability during hot-swapping or live insertion is critical.
Part Context
This part belongs to the 5962-92213 family of fast CMOS octal buffers. It is equivalent to the IDT 54FCT240T but qualified for military standards. The device is designed for demanding applications requiring robust signal integrity and wide operating temperature ranges.
Replacement Considerations
The commercial version 74FCT240T offers similar functionality but lacks military qualification. Verify pinout and electrical characteristics match before substitution. No other direct military equivalents are confirmed in public documentation.
