Product details
Overview
5962-8860601EQ from Texas Instruments is a high-speed CMOS 3-to-8 line decoder/demultiplexer with address latches, designed for military-grade memory address decoding and data routing in harsh environments. It features active-high outputs, dual output enables (OE0/OE1), latch enable (LE), three binary select inputs (A0–A2), and operates across –55°C to +125°C at 4.5V–5.5V supply. Its typical propagation delay is 16ns at VCC = 5V, CL = 15pF, TA = 25°C.
For engineers reviewing the 5962-8860601EQ datasheet, 5962-8860601EQ pinout, 5962-8860601EQ application, or 5962-8860601EQ equivalent, this device serves as a radiation-tolerant, temperature-hardened alternative to commercial CD74HC237/CD74HCT237 variants - critical for aerospace avionics, missile guidance logic, and secure embedded control systems requiring MIL-PRF-38535 Class Q compliance.
Technical Context
This device implements a 3-bit address latch followed by an active-high 1-of-8 decoder, enabling transparent or latched operation via LE. Output selection is controlled by A0–A2, while OE0 and OE1 provide hierarchical enable control for cascading and demultiplexing functions - OE0 used as data input when OE1 is held active.
It belongs to the CD54HC237 family (HCMOS), specified for 4.5V–5.5V operation with TTL-compatible inputs (VIH ≥ 2V, VIL ≤ 0.8V) and CMOS-level outputs. Propagation delays are characterized under load conditions up to 50pF, with guaranteed timing over full military temperature range and latch setup/hold times validated down to –55°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| 9, 10, 11 | A0, A1, A2 Inputs | 3-bit binary address inputs; latched on rising edge of LE when enabled |
| 12 | OE1 | Primary output enable - must be low for any output to be active |
| 13 | OE0 | Secondary output enable - used as data input during demultiplexing mode |
| 14 | LE | Latch Enable - high enables transparent mode; low latches current address |
| 16 | VCC | Positive supply rail (4.5V–5.5V); decoupling required per MIL-STD-1399 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-to-8 decoder/demultiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD74HC237E | Commercial PDIP variant; same logic function but rated only for –55°C to +125°C with non-hermetic plastic package and no MIL-PRF-38535 qualification | Lacks radiation hardness, moisture resistance, and long-term reliability validation required for flight-critical systems | Select only for ground-test fixtures or non-flight prototypes where cost and availability outweigh qualification needs |
| CD74HCT237E | HCT version with identical pinout and timing, but optimized for strict TTL input compatibility (VIH = 2V min, VIL = 0.8V max) and tighter VCC tolerance (4.5V–5.5V) | Suitable for mixed-logic systems with legacy TTL drivers, but not certified for military environmental or screening requirements | Prefer when interfacing with older 74LS-series controllers and no radiation/moisture specs apply |
Compared with CD74HC237E and CD74HCT237E, the 5962-8860601EQ delivers assured performance under shock, vibration, and thermal cycling per MIL-STD-810, plus hermetic reliability and traceable lot documentation - making it the sole choice for deployed DoD and NASA platforms where failure is not an option.

FAQ
What is the full military specification compliance status of the 5962-8860601EQ?
The 5962-8860601EQ is fully compliant with MIL-PRF-38535 Class Q, including screening per MIL-STD-883 Methods 1010 (temperature cycling), 2001 (steady-state life), and 2011 (burn-in). It carries QML certification and is listed on the Qualified Manufacturers List (QML) for high-reliability microcircuits used in U.S. Department of Defense systems.
Does the 5962-8860601EQ support demultiplexing functionality, and how is it implemented?
Yes, the 5962-8860601EQ supports demultiplexing by using OE0 as the data input while holding OE1 low and selecting the output channel via A0–A2. When OE1 is active (low), the selected Yx output mirrors the logic state of OE0 - enabling single-line-to-eight-line signal distribution without additional logic gates.
What is the maximum capacitive load the 5962-8860601EQ can drive while maintaining specified timing?
The 5962-8860601EQ is characterized for CL = 50pF in switching specifications, with propagation delays guaranteed up to that load. For CL > 50pF, timing degrades linearly; design margin requires limiting total net capacitance (including PCB trace and fanout) to ≤45pF to retain 16ns typical delay at 5V and 25°C.
Is the 5962-8860601EQ pin-compatible with commercial CD74HC237 variants?
Yes, the 5962-8860601EQ shares identical pinout, logic function, and electrical interface with CD74HC237 and CD74HCT237 in 16-lead CERDIP and PDIP packages. However, its CERDIP package has different lead pitch and body dimensions than PDIP - PCB layout must match the J (CERDIP) footprint, not N (PDIP).
What are the recommended decoupling practices for the 5962-8860601EQ in high-reliability designs?
Per MIL-STD-1399 and TI's application guidance, use a minimum of one 100nF X7R ceramic capacitor placed within 2mm of VCC and GND pins, plus a bulk 10µF tantalum capacitor per power domain. All capacitors must meet MIL-PRF-123 or MIL-PRF-55681, and traces shall be wide (>0.5mm) and short (<5mm) to minimize inductance.
