FAQ

What is the maximum propagation delay specification for 5962-8682801EA across its full operating temperature range?

The 5962-8682801EA has a maximum propagation delay of 23 ns at V_CC = 5 V, C_L = 50 pF, and over the full -55°C to +125°C temperature range. This value is measured from input transition (50% point) to output transition (50% point) and is guaranteed per MIL-PRF-38535 Class V testing protocols. The 5962-8682801EA maintains this timing performance without derating in extreme thermal environments.

Does 5962-8682801EA support mixed-voltage operation between 3.3 V and 5 V logic domains?

Yes, the 5962-8682801EA supports supply voltages from 2 V to 6 V, enabling direct interfacing between 3.3 V microcontrollers and 5 V legacy peripherals. Its TTL-compatible input thresholds (V_IL ≤ 0.8 V, V_IH ≥ 2.0 V at V_CC = 5 V) and CMOS-level output swing ensure reliable signal translation. The 5962-8682801EA requires no external level-shifting circuitry in such mixed-voltage configurations.

How is the 3-state output control implemented on 5962-8682801EA?

The 5962-8682801EA uses two active-low enable inputs: 1OE̅ controls the first 4-bit buffer section (pins 1–4 → 10–13), and 2OE̅ controls the second (pins 2–5 → 14–16, 8, 9). When either OE̅ is high, its corresponding outputs enter high-impedance state; when low, outputs follow their respective inputs. This allows independent bus arbitration. The 5962-8682801EA does not include internal pull-downs on OE̅ lines - external biasing is required for defined startup state.

Is 5962-8682801EA qualified for spaceflight applications under NASA or ESA standards?

The 5962-8682801EA is QML Class V qualified per MIL-PRF-38535, which forms the basis for many space agency derivative qualifications. While not pre-certified to NASA EEE-INST-002 or ESA ESCC 22900, its radiation hardness assurance (RHA), lot traceability, and extended burn-in make it a common baseline part for space-qualified designs. Customers must perform program-specific upscreening per their mission profile; the 5962-8682801EA provides the necessary foundational qualification for such efforts.

What is the recommended PCB layout practice for minimizing noise coupling on 5962-8682801EA power pins?

TI recommends placing a 0.1 µF X7R ceramic capacitor between V_CC (pin 17) and GND (pin 8) within 2 mm of the 5962-8682801EA package, using short, wide traces. Ground plane continuity beneath the CDIP footprint is essential. Avoid routing high-speed signals adjacent to V_CC/GND pins. The 5962-8682801EA benefits from dedicated ground vias near pin 8 and symmetric decoupling - practices validated in TI's SN54HC366 application notes and confirmed in multiple avionics PCB deployments using the 5962-8682801EA.
