Overview
The Texas Instruments 5962-9761601QCA is a military-grade D-type flip-flop belonging to the LVC/LCX/Z series. It features two positive-edge-triggered functions with complementary outputs in a 14-pin ceramic dual in-line package (CDIP). The device operates from a supply voltage range of 1.65V to 3.6V, while inputs accept voltages up to 5.5V. It achieves a maximum propagation delay of 5.2ns at 3.3V and exhibits typical output ground bounce characteristics.
Feature Summary
- Dual positive-edge triggered D-type flip-flop configuration with complementary outputs
- Input tolerance allows acceptance of voltages up to 5.5V despite lower core operation
- High-speed performance with maximum propagation delay of 5.2ns at 3.3V
- Military-grade construction utilizing a 14-lead ceramic dual in-line package
Applications
- Military electronic systems requiring radiation-hardened or high-reliability logic
- Data storage registers in aerospace computing environments
- State machines for defense communication equipment
- Industrial control systems operating under extreme temperature conditions
Procurement Notes
Verify that the specific ordering suffix matches the required military qualification level and package variant. Confirm that the input voltage specifications align with system interface requirements, particularly regarding the 5.5V tolerance capability. Ensure that the thermal management strategy supports the specified operating temperature range for the ceramic package environment.
Selection Notes
Select this component when a dual-function D-type flip-flop with complementary outputs is required for high-speed digital applications. The wide input voltage tolerance provides flexibility for interfacing with different logic families. Consider the CDIP package for through-hole mounting in ruggedized designs where standard surface-mount packages are unsuitable.
Part Context
This part belongs to the SN54LVC2D125 family of dual D-type flip-flops manufactured by Texas Instruments. The 5962 prefix indicates a Department of Defense microelectronics procurement number, signifying that the device meets strict military quality and reliability standards beyond commercial specifications.
Replacement Considerations
Direct replacements include other military-qualified parts within the SN54LVC2D125 family. Verify pinout compatibility and electrical parameters before substituting with equivalent components from other manufacturers offering similar military-grade logic solutions.
