Product details
Overview
CY54FCT240T from Texas Instruments is a military-grade octal buffer/line driver with 3-state outputs, designed for memory address and clock distribution in high-reliability systems operating from –55°C to 125°C. It delivers 48-mA sink / 12-mA source drive, 4.7 ns max propagation delay, Ioff-enabled partial-power-down protection, and TTL-compatible input/output logic levels.
For engineers reviewing the 5962-9221305MRA datasheet, 5962-9221305MRA pinout, 5962-9221305MRA application, or 5962-9221305MRA equivalent, this page provides verified functional identity, CDIP-20 package mapping, MIL-PRF-38535 compliance status, drive capability specs, and direct alternatives for radiation-tolerant bus interface designs.
Technical Context
The 5962-9221305MRA implements dual 4-bit noninverting buffers with independent 3-state enable controls (OEA and OEB), supporting bidirectional bus isolation. Its edge-rate control circuitry suppresses switching noise while maintaining matched rise/fall times under load.
It features Ioff circuitry that disables outputs and limits backflow current when VCC = 0 V, enabling safe hot-insertion and partial-power-down operation. Input thresholds are TTL-compatible (VIH = 2 V min, VIL = 0.8 V max), and output voltage levels meet both TTL and CMOS interface requirements.
Key Specifications

FAQ
What is the exact device type and function of 5962-9221305MRA?
The 5962-9221305MRA is a CY54FCT240T octal noninverting buffer with dual 3-state output enables (OEA and OEB), manufactured by Texas Instruments and qualified per MIL-PRF-38535 Class B. It functions as a high-drive, low-noise bus interface device for memory address, clock, and control signal distribution in harsh-environment systems.
Does 5962-9221305MRA support partial-power-down operation?
Yes, 5962-9221305MRA incorporates Ioff circuitry that disables outputs and limits leakage to ±1 µA when VCC = 0 V. This feature allows safe insertion into live backplanes and prevents damaging current backflow during power sequencing - a critical requirement for MIL-STD-1553 and ARINC-429 subsystems.
What is the maximum propagation delay for 5962-9221305MRA over its full temperature range?
The maximum propagation delay (tPLH/tPHL) for 5962-9221305MRA is 4.7 ns at VCC = 4.5 V and TA = –55°C to +125°C, as specified in the CY54FCT240T datasheet SCCS017A. This value applies to the CY54FCT240T variant in CDIP-J packaging, which matches the 5962-9221305MRA configuration.
Is 5962-9221305MRA pin-compatible with commercial CY74FCT240T devices?
No - 5962-9221305MRA uses the CDIP-J package with 20 pins and follows the CY54FCT240T pinout, while commercial CY74FCT240T variants use SOIC-DW or SSOP-DBQ packages with different mechanical dimensions and thermal characteristics. Electrical functionality is identical, but PCB layout and thermal design are not interchangeable.
