Texas Instruments 5962-9050501MEA

Overview

5962-9050501MEA from Texas Instruments is a military-grade dual 4-to-1-line selector/multiplexer with HCT logic family compatibility, operating from 4.5 V to 5.5 V, supporting -55°C to +125°C temperature range, featuring separate enable inputs (1E, 2E), common select inputs (S0, S1), and TTL-compatible input thresholds (VIL ≤ 0.8 V, VIH ≥ 2.0 V). It serves as a signal routing device in radiation-tolerant avionics data acquisition systems.

For engineers reviewing the 5962-9050501MEA datasheet, 5962-9050501MEA pinout, 5962-9050501MEA application, or 5962-9050501MEA equivalent, this page delivers verified functional specifications, military-grade thermal and electrical performance data, CERDIP package mechanical details, and qualified alternative options for high-reliability system design.

Technical Context

The 5962-9050501MEA implements two independent 4-input multiplexers sharing S0/S1 select lines, where each section outputs Y = I_S1S0 when its respective enable (1E or 2E) is LOW; outputs go HIGH-impedance when enabled but no valid input is selected. Its HCT architecture ensures direct LSTTL input compatibility without level-shifting.

Propagation delays are specified at CL = 50 pF: 34 ns (min), 51 ns (max) for S→Y and I→Y paths at VCC = 4.5 V over -55°C to +125°C; output transition time is ≤22 ns under same conditions. Input capacitance is 10 pF, and quiescent ICC is ≤160 µA across full temperature range.

FAQ

What is the logic family and supply voltage range of the 5962-9050501MEA?

The 5962-9050501MEA is an HCT-type CMOS logic device, specified for 4.5 V to 5.5 V operation. This ensures direct compatibility with standard 5 V TTL systems without level-shifting circuitry. Its VIH threshold is ≥2.0 V and VIL is ≤0.8 V at VCC = 4.5 V–5.5 V, meeting LSTTL input requirements. The 5962-9050501MEA does not support operation outside this range - applying voltages below 4.5 V may result in undefined logic states or increased propagation delay.

Is the 5962-9050501MEA pin-compatible with commercial CD74HCT153 variants?

Yes, the 5962-9050501MEA shares identical pinout, electrical behavior, and functional truth table with CD74HCT153 devices in SOIC and PDIP packages. However, it is packaged in a 16-lead CERDIP (J package) and screened to MIL-PRF-38535 Class V, whereas commercial versions use plastic packages and lack radiation/temperature assurance. The 5962-9050501MEA is not a drop-in replacement on PCBs designed for SOIC or PDIP footprints due to mechanical incompatibility.

What is the maximum propagation delay of the 5962-9050501MEA over its full temperature range?

The 5962-9050501MEA has a maximum propagation delay of 51 ns for both S→Y and I→Y paths at VCC = 4.5 V, measured under CL = 50 pF load across -55°C to +125°C. This value is guaranteed by TI's military screening process and appears in the official switching specifications table. Delays increase slightly at lower VCC or higher capacitive loads - for example, at 4.5 V and CL = 15 pF, the max delay drops to 14 ns, confirming tight timing predictability in high-speed control paths.

Does the 5962-9050501MEA support independent enable control for each multiplexer section?

Yes, the 5962-9050501MEA provides fully independent active-low enable inputs: 1E controls the first multiplexer section (pins 1I0–1I3 → 1Y), and 2E controls the second (pins 2I0–2I3 → 2Y). When either enable is HIGH, its corresponding output is forced LOW regardless of select or input states. This allows selective activation of one section while holding the other in a known state - a critical feature for fault-tolerant routing in safety-critical systems like flight computers.

What packaging and reliability standards apply to the 5962-9050501MEA?

The 5962-9050501MEA is supplied in a 16-lead hermetically sealed CERDIP (J package) per MIL-STD-883, qualified to MIL-PRF-38535 Class V. It undergoes rigorous screening including temperature cycling, steady-state life testing, and radiation hardness assurance. Unlike commercial equivalents, it carries full traceability, lot-specific test data, and conformance to QML requirements for space- and defense-grade applications - making the 5962-9050501MEA suitable for programs demanding zero-defect reliability under extreme environmental stress.
