Product details

Overview

5962-9469101QLA from Texas Instruments is a military-grade 10-bit bus-interface D-type flip-flop with 3-state outputs, designed for high-speed bidirectional bus buffering in avionics and defense systems. It operates across –55°C to 125°C, delivers ±32-mA high-drive outputs, supports 125-MHz clock frequency, and features power-up/power-down high-impedance state for bus isolation.

For engineers reviewing the 5962-9469101QLA datasheet, 5962-9469101QLA pinout, 5962-9469101QLA application, or 5962-9469101QLA equivalent, this device is selected for deterministic edge-triggered data latching, robust ESD protection (>2000 V), latch-up immunity (>500 mA), and compatibility with TTL-level control signals in radiation-tolerant embedded timing paths.

Technical Context

This device implements ten independent positive-edge-triggered D-type flip-flops with a shared clock (CLK) and buffered output-enable (OE) control. Each flip-flop captures true data on CLK↑ and drives Q outputs with BiCMOS EPIC-II^B logic, enabling low propagation delay (t_PLH/t_PHL ≤ 6.9 ns) and minimal ground bounce (V_OLP < 1 V).

The OE input controls all ten outputs simultaneously into high-impedance (Z) state without affecting internal latch operation-allowing data retention or update during bus float. Power sequencing is supported: outputs enter high-Z when V_CC is between 0–2.1 V, and OE must be pulled to V_CC above 2.1 V to guarantee Z-state integrity.

Key Specifications

FAQ

What is the operating temperature range specified for the 5962-9469101QLA?

The 5962-9469101QLA is characterized for operation from –55°C to 125°C, meeting MIL-PRF-38535 Class B requirements. This full military temperature range ensures reliable performance in extreme environments such as jet engine bays, missile guidance sections, and orbital thermal cycling-without derating or thermal management overhead.

Does the 5962-9469101QLA support hot-swap or live-insertion on a powered bus?

The 5962-9469101QLA does not include explicit hot-swap circuitry, but its high-impedance state during power-up (V_CC < 2.1 V) and robust ESD protection (>2000 V) provide inherent tolerance for controlled live insertion. For guaranteed safe hot-swap, external current-limiting and slew-rate control on OE and CLK lines are recommended per MIL-STD-1523B guidelines.

What is the maximum clock frequency supported by the 5962-9469101QLA?

The 5962-9469101QLA supports a maximum clock frequency of 125 MHz across its full operating temperature range. This value is validated per the switching characteristics table in the SCBS193E datasheet and applies to both SN54ABT821 and its 5962-9469101QLA variant, enabling high-throughput data staging in real-time avionics subsystems.

How does the output-enable (OE) pin behave when V_CC is below 2.1 V?

When V_CC is between 0 V and 2.1 V, the 5962-9469101QLA automatically places all ten outputs in high-impedance state regardless of OE voltage level-ensuring bus isolation during power ramp-up or brownout. Above 2.1 V, OE must be actively driven high (≥2 V) to maintain high-Z, typically via a pullup resistor to V_CC.

Is the 5962-9469101QLA RoHS compliant?

The 5962-9469101QLA is a ceramic DIP (JT) device manufactured under MIL-PRF-38535 and is exempt from RoHS compliance requirements per EU Directive 2011/65/EU Annex III. Its lead content is permitted under military exemption 7a, and it is intended for critical defense/aerospace applications where reliability supersedes RoHS restrictions.
