Texas Instruments 5962-9761601Q2A

Overview

5962-9761601Q2A from Texas Instruments is a dual positive-edge-triggered D-type flip-flop with independent preset and clear inputs, designed for 2.7-V to 3.6-V operation across –55°C to 125°C. It delivers 5.2 ns maximum propagation delay at 3.3 V, supports 5.5 V-tolerant inputs, and meets MIL-PRF-38535 Class V requirements for high-reliability aerospace and defense systems.

For engineers reviewing the 5962-9761601Q2A datasheet, 5962-9761601Q2A pinout, 5962-9761601Q2A application, or 5962-9761601Q2A equivalent, this device serves as a radiation-hardened, temperature-qualified building block for synchronous logic control, clock domain interfacing, and state retention in mission-critical avionics and spaceborne electronics.

Technical Context

The 5962-9761601Q2A implements two independent D flip-flops sharing no internal coupling-each with dedicated CLK, D, PRE, CLR, Q, and Q̅ terminals. Its latch-up immunity exceeds 250 mA per JESD 17, and ESD protection meets ±2000-V HBM and ±1000-V CDM per JESD 22.

Triggering occurs at a defined voltage threshold on the rising edge of CLK, decoupled from input slew rate. PRE and CLR are asynchronous active-low controls that override clocked data transfer, enabling deterministic initialization and reset without clock dependency.

FAQ

What is the qualified temperature range for 5962-9761601Q2A?

The 5962-9761601Q2A is fully qualified from –55°C to 125°C per MIL-PRF-38535 Class V requirements. This range is verified through temperature cycling, steady-state life testing, and parametric validation at extremes-ensuring reliable operation in stratospheric avionics and deep-space probe electronics where thermal gradients exceed commercial-grade limits. All timing and DC parameters in the 5962-9761601Q2A datasheet apply across this full range.

Does 5962-9761601Q2A support mixed-voltage interfacing?

Yes, the 5962-9761601Q2A supports mixed-voltage interfacing via 5.5 V-tolerant inputs. Inputs accept voltages up to 5.5 V regardless of VCC (2.7–3.6 V), enabling direct connection to legacy 5 V logic families without external level shifters. This capability is confirmed in the Absolute Maximum Ratings table and validated across temperature for both SN54LVC74A and SN74LVC74A variants in the official TI datasheet SCAS287U.

How does the asynchronous preset/clear function operate in 5962-9761601Q2A?

In the 5962-9761601Q2A, PRE and CLR are active-low asynchronous controls: pulling either low forces the corresponding Q output to logic high (PRE) or low (CLR) immediately, overriding clock and data inputs. This behavior is documented in the Function Table (Table 1) and applies independently per channel. No clock edge is required, making it ideal for emergency reset or power-on initialization in safety-critical systems.

What package type does 5962-9761601Q2A use, and why is it suited for high-reliability applications?

The 5962-9761601Q2A uses a 20-pin LCCC (FK) package with an 8.89 mm × 8.89 mm ceramic body and metallized leads. Its hermetic seal, low outgassing, and coefficient-of-thermal-expansion match to alumina PCBs make it resistant to moisture ingress, thermal shock, and mechanical vibration-key requirements for launch environments and long-duration space missions where plastic packages would fail.

Is 5962-9761601Q2A pin-compatible with other SNx4LVC74A variants?

No-5962-9761601Q2A uses a 20-pin LCCC footprint, while other SNx4LVC74A variants like SNJ54LVC74AJ (14-pin CDIP) or SN74LVC74AD (14-pin SOIC) have different pin counts and layouts. Pin compatibility exists only within same-package variants (e.g., 5962-9761601Q2A and SNJ54LVC74AFK share the FK LCCC pinout). Electrical functionality is identical, but PCB layout must be redesigned for LCCC mounting.
