Product details
Overview
5962-9061601LA from Texas Instruments is a military-grade 10-bit edge-triggered D-type flip-flop with 3-state outputs, designed for high-capacitance bus driving in avionics and defense systems. It operates across −55°C to 125°C, features 48 mA low-level output drive, 24 mA high-level sink capability, and 7 ns minimum clock pulse width.
For engineers reviewing the 5962-9061601LA datasheet, 5962-9061601LA pinout, 5962-9061601LA application, or 5962-9061601LA equivalent, key selection criteria include its ceramic DIP-24 package, undershoot-protection circuitry, power-up high-impedance state, and functional equivalence to AM29821 in wide-address buffer and parity bus implementations.
Technical Context
This device implements ten independent D-type latches synchronized on the rising edge of CLK, with each Q output mirroring its corresponding D input at clock transition. OE controls all ten outputs simultaneously into high-impedance or active logic states without affecting internal latch operation.
It uses ALS (Advanced Low-Power Schottky) bipolar technology, delivering TTL-compatible voltage thresholds (VIH = 2 V, VIL = 0.8 V), fast propagation delays (tPLH/tPHL ≤ 11.5 ns at CL = 50 pF), and robust 3-state enable/disable timing (tPZH/tPLZ ≤ 17 ns).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | ALS (Advanced Low-Power Schottky) - enables TTL-compatible interfacing with reduced power vs standard LS. |
| Operating Temperature | −55°C to 125°C - qualified per MIL-PRF-38535 for extended-range military and aerospace use. |
| Output Drive | IOL = 48 mA / IOH = −24 mA - sufficient to drive heavy capacitive buses without external buffers. |
| Propagation Delay | tPLH/tPHL ≤ 11.5 ns (CL = 50 pF) - supports reliable timing in high-speed address/data path expansion. |
| Setup/Hold Times | tsu = 4 ns, th = 2 ns - tight timing margins compatible with fast synchronous bus protocols. |
| Supply Voltage | VCC = 4.5 V to 5.5 V - stable operation across wide rail tolerance required in ruggedized power supplies. |
Pinout & Package
Ceramic Dual-In-Line Package (CDIP), JT outline, 24-pin, 0.3-inch width, hermetically sealable per MIL-STD-1835 GDIP3-T24. Pin 1 marked by cap index point; seating plane defined per JEDEC MO-058 AA.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OE | Active-low 3-state output enable - places all Q outputs in high-Z when low; no effect on internal latch state. |
| 2–11 | 1D–10D | Data inputs - sampled on rising CLK edge; asynchronous to OE control. |
| 12 | GND | Ground reference - common return for all logic and output current paths. |
| 13 | VCC | Positive supply - powers internal logic and output drivers; decoupling required near pin. |
| 14–23 | 1Q–10Q | 3-state buffered outputs - drive high/low or float based on OE and CLK-sampled D value. |
| 24 | CLK | Positive-edge clock - triggers simultaneous latching of all ten D inputs to respective Q outputs. |
Key Features
| Feature | Design Value |
|---|---|
| Undershoot-protection circuitry | Prevents negative transient damage on data/control lines during hot-swap or ESD events in mission-critical backplanes. |
| Power-up high-impedance state | Eliminates bus contention at power-on/off transients - critical for fault-tolerant system initialization. |
| Buffered control inputs | Reduces DC loading on OE and CLK lines, enabling fanout to multiple devices without signal degradation. |
| Functionally equivalent to AM29821 | Enables drop-in replacement in legacy AMD-based military designs without redesign or requalification. |
| Wide temperature range support | Validated operation from −55°C to 125°C ensures reliability in uncontrolled environmental enclosures and airborne platforms. |
Applications
| Aerospace Data Bus Interface | Military Memory Address Latch |
|---|---|

Use Scenario: Storing intermediate computation results in embedded cryptographic accelerators used in secure comms subsystems. IC Role / Device Role / Timing Role: Synchronous working register retaining data during pipeline stalls; OE allows concurrent read/write via shared bus. Use Value: Retains valid data while outputs are tri-stated - essential for non-blocking register file access in real-time encryption engines. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 10-bit 3-state D-flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54ALS29821JT | Identical die, same JT package, identical military screening - functionally and physically interchangeable. | No difference; same qualification level and marking per MIL-PRF-38535 Class V. | Select when sourcing through TI's official military distribution channel with full traceability. |
| AM29821 | Original AMD part; pinout and AC/DC specs match per datasheet cross-reference - confirmed functional equivalence. | Legacy AMD-based designs may require original AM29821 for obsolescence management or documentation alignment. | Use only if AM29821 remains available and certified for the target program's configuration baseline. |
Compared with SNJ54ALS29821JT and AM29821, the 5962-9061601LA offers identical electrical behavior and military temperature rating but carries formal QML-38535 certification with lot traceability - making it preferred for new DoD hardware releases requiring full pedigree documentation.

FAQ
What is the operating temperature range for the 5962-9061601LA?
The 5962-9061601LA is characterized for operation from −55°C to 125°C, meeting MIL-PRF-38535 Class V requirements. This full military temperature range ensures reliable functionality in extreme environments such as aircraft bays, missile guidance sections, and space-qualified electronics where thermal cycling exceeds commercial limits. The 5962-9061601LA maintains specified timing and drive performance across this entire range without derating.
Is the 5962-9061601LA pin-compatible with the SN74ALS29821DW?
No - the 5962-9061601LA uses a ceramic DIP-24 (JT) package, while the SN74ALS29821DW uses a plastic SOIC-24 (DW) package. Although both share identical pin functions and logic behavior, their physical footprints, thermal characteristics, and moisture sensitivity levels differ significantly. The 5962-9061601LA requires through-hole mounting and hermetic handling, whereas the DW variant is surface-mount and RoHS-compliant. The 5962-9061601LA is not a drop-in PCB replacement for the DW version.
Does the 5962-9061601LA support hot-swap or live-insertion?
The 5962-9061601LA features undershoot-protection circuitry on all inputs and outputs, and enters a guaranteed high-impedance state during power-up and power-down transitions. While these features improve robustness during partial-power conditions, the device is not explicitly qualified for hot-swap per IEEE 1394 or PCI standards. Its use in live-insertion scenarios requires external sequencing and clamping - the 5962-9061601LA itself provides foundational protection but does not eliminate need for system-level safeguards.
What is the maximum capacitive load the 5962-9061601LA can drive reliably?
The 5962-9061601LA is specified for CL = 50 pF and CL = 300 pF in its switching characteristics table, with tPLH/tPHL ≤ 21 ns at 300 pF. Its 48 mA low-level output drive and undershoot protection allow stable operation into loads exceeding 300 pF when combined with proper transmission line termination. For sustained reliability in high-Cbus applications like backplane interconnects, layout best practices (short traces, ground planes) remain essential - the 5962-9061601LA enables such designs but does not eliminate signal integrity constraints.
How does the 5962-9061601LA handle output contention during power transitions?
The 5962-9061601LA guarantees high-impedance outputs during power-up and power-down, preventing bus contention even when VCC ramps slowly or asymmetrically. This behavior is inherent to its internal power-on reset circuitry and does not depend on OE state. As a result, multiple 5962-9061601LA devices sharing a common bus will not source or sink current into each other during supply sequencing - a critical feature for fault-tolerant avionics architectures where staggered power application is routine. The 5962-9061601LA enforces this behavior across its full −55°C to 125°C range.
