Texas Instruments 5962-9062501M2A

Overview

5962-9062501M2A from Texas Instruments is a military-grade octal noninverting buffer/line driver IC with dual 4-bit channels, 3-state outputs, P-N-P input structure, BiCMOS process, and −55°C to +125°C operation. It delivers 48 mA low-level output drive, 2.4 V minimum VOH at −12 mA, and 5 ns typical propagation delay (tPHL/tPLH) under 50 pF load.

For engineers reviewing the 5962-9062501M2A datasheet, 5962-9062501M2A pinout, 5962-9062501M2A application, or 5962-9062501M2A equivalent, this device serves as a high-reliability address/data bus driver in radiation-tolerant avionics, missile guidance logic, and secure military computing systems where bus isolation, DC loading reduction, and ESD robustness (>2000 V per MIL-STD-883C) are critical.

Technical Context

The 5962-9062501M2A implements two independent 4-bit noninverting buffers, each with active-low output-enable (OE) control. Its P-N-P input stage minimizes DC loading on upstream TTL or BCT logic, while BiCMOS output drivers combine bipolar switching speed with CMOS quiescent current efficiency (ICCZ ≤ 10 mA).

It supports true 3-state bus driving with symmetrical OE inputs, fast enable/disable timing (tPZH/tPZL ≤ 9 ns), and operates across full military temperature range using 4.5 V–5.5 V supply. Input clamping (VIK = −1.2 V), output voltage tolerance (VO ≤ 5.5 V in disabled state), and −100 mA short-circuit current rating ensure robust system-level interfacing.

FAQ

What is the operating temperature range of the 5962-9062501M2A?

The 5962-9062501M2A is characterized for operation from −55°C to +125°C, meeting MIL-PRF-38535 Class V requirements for extended environmental survivability in airborne and spaceborne platforms. This range is verified per Test Method 1010 of MIL-STD-883 and applies to all electrical parameters in the datasheet, including propagation delay, output drive, and input thresholds.

Is the 5962-9062501M2A pin-compatible with commercial SN74BCT244 variants?

No - the 5962-9062501M2A uses a 20-pin LCCC (FK) package, whereas commercial SN74BCT244 variants use SOIC (DW), PDIP (N), or NS packages. Pin functions are identical (1OE, 1A1–1A4, 1Y1–1Y4, etc.), but physical layout, soldering method, and thermal characteristics differ significantly. Board redesign is required to substitute 5962-9062501M2A into a commercial footprint.

Does the 5962-9062501M2A support hot-swap or live-insertion?

The 5962-9062501M2A includes input clamping (VIK = −1.2 V) and output voltage limits (VO ≤ 5.5 V in disabled state), which provide partial protection during live insertion. However, it lacks explicit hot-swap control circuitry such as slew-rate limiting or undervoltage lockout. System-level implementation - including series resistors, RC filters, and sequencing controllers - is required to ensure safe hot-swap operation in backplane applications.

What is the maximum capacitive load the 5962-9062501M2A can drive reliably?

The 5962-9062501M2A is specified for CL = 50 pF in switching characteristics tables, with tPLH/tPHL measured under that condition. While it can drive higher capacitance (e.g., 100 pF) with degraded timing (increased propagation delay and reduced edge rate), sustained operation above 50 pF may violate setup/hold margins in high-speed buses. For >50 pF loads, TI recommends verifying timing margins using worst-case VCC, temperature, and process corners.

How does the BiCMOS process benefit the 5962-9062501M2A in military applications?

The BiCMOS process in the 5962-9062501M2A combines bipolar transistors for high-speed switching (enabling 5 ns propagation delay) with CMOS circuitry for ultra-low quiescent current (ICCZ ≤ 10 mA). This dual advantage reduces both dynamic power consumption during high-frequency bus activity and static power draw during standby - essential for battery-limited munitions and thermally constrained avionics enclosures.
