Texas Instruments 5962-9861601QEA

Overview

5962-9861601QEA from Texas Instruments is a dual retriggerable monostable multivibrator in CDIP-J package, operating from –55°C to 125°C with 5 V ±0.5 V supply, TTL-compatible inputs, Schmitt-trigger A/B/CLR inputs, and external RC-controlled pulse duration up to milliseconds. It serves as a precision timing element in military-grade digital systems requiring jitter-free edge triggering and pulse extension.

For engineers reviewing the 5962-9861601QEA datasheet, 5962-9861601QEA pinout, 5962-9861601QEA application, or 5962-9861601QEA equivalent, key selection criteria include its MIL-PRF-38535 qualification, dual independent monostable operation, retriggerable pulse control, overriding clear functionality, and compatibility with legacy TTL logic families in harsh-environment timing circuits.

Technical Context

The 5962-9861601QEA implements two independent edge-triggered monostables, each accepting active-high or active-low gated logic inputs (A, B) with Schmitt-trigger hysteresis for noise immunity against slow transitions. Triggering occurs at defined voltage thresholds-not transition rate-enabling reliable operation with non-ideal waveforms.

Pulse duration is externally programmed via R_ext and C_ext connected to dedicated pins; retriggering extends output pulses while CLR assertion terminates them early. Output pulse variation is <±0.5% across devices under matched RC conditions, and latch-up performance exceeds 100 mA per JESD 78 Class II.

FAQ

What is the operating temperature range of the 5962-9861601QEA?

The 5962-9861601QEA operates from –55°C to +125°C, fully qualified per MIL-PRF-38535 for extended-temperature military applications. This range is verified across all electrical parameters in the datasheet, including propagation delay, output drive, and pulse duration stability, making it suitable for deployment in jet engines, space launch systems, and ground vehicles exposed to extreme ambient conditions.

Does the 5962-9861601QEA require external components to function?

Yes-the 5962-9861601QEA requires external R_ext and C_ext components connected to dedicated pins (e.g., 1R_ext/C_ext, 1C_ext) to set output pulse duration. The device will not generate timed pulses without these components; however, basic logic-level pass-through (e.g., CLR override) remains functional even with unconnected timing terminals.

Is the 5962-9861601QEA pin-compatible with commercial SN74AHCT123A variants?

No-while electrically identical, the 5962-9861601QEA uses a 16-pin CDIP-J package with 2.54 mm lead pitch and ceramic construction, whereas commercial SOIC (D), TSSOP (PW), and PDIP (N) variants have different footprints, thermal characteristics, and moisture sensitivity levels. PCB layout and assembly processes are not interchangeable.

How does the retriggering function work on the 5962-9861601QEA?

Retriggering extends the current output pulse duration: when an active A or B input transitions during an ongoing pulse, the timer resets and begins a new full-duration cycle. Minimum retrigger interval is ~15 ns, and pulse extension follows t_RT = K·R_ext·C_ext + t_PLH. This allows dynamic pulse lengthening without external logic-used in adaptive debounce and variable-interval watchdogs.

What certifications apply to the 5962-9861601QEA?

The 5962-9861601QEA is certified to MIL-PRF-38535 Class V (QML-38535), with full screening including burn-in, temperature cycling, and radiation hardness assurance. It meets JESD 78 Class II latch-up immunity (>100 mA), JESD 22 ESD ratings (2000-V HBM), and RoHS-exempt status due to leaded ceramic packaging required for military reliability.
