Texas Instruments 5962-9686001QCA

Overview

5962-9686001QCA from Texas Instruments is a dual positive-edge-triggered D-type flip-flop with independent preset and clear inputs, operating across 2 V to 5.5 V supply voltage, supporting 130 MHz maximum clock frequency at 5 V, and rated for –55°C to +125°C military temperature range in a 14-pin ceramic dual in-line package (CDIP). It functions as a synchronous storage element in digital control logic, state machines, and data synchronization circuits.

For engineers reviewing the 5962-9686001QCA datasheet, 5962-9686001QCA pinout, 5962-9686001QCA application, or 5962-9686001QCA equivalent, this device serves as a radiation-tolerant, high-reliability building block for aerospace timing, avionics sequencing, and hardened digital systems requiring deterministic edge-triggered state retention under extended thermal and electrical stress.

Technical Context

The 5962-9686001QCA implements two independent D-type latches synchronized to the rising edge of CLK, each with asynchronous active-low PRE and CLR inputs that override clocked behavior. Its CMOS AHC logic family ensures rail-to-rail output swing, low static current (≤20 µA at 25°C), and noise immunity via hysteresis-free input thresholds defined relative to VCC.

Timing is characterized across –55°C to +125°C with guaranteed setup (3 ns min at 5 V) and hold (0.5 ns min) times, and propagation delays as low as 4.6 ns (tPLH, CLK→Q, CL = 15 pF). Input transition rate limits (20 ns/V at 5 V) and latch-up immunity (>250 mA per JESD 17) support robust operation in noisy, high-dI/dt environments.

FAQ

What is the maximum clock frequency supported by the 5962-9686001QCA at 5 V supply?

The 5962-9686001QCA supports a maximum clock frequency of 130 MHz when operating at VCC = 5 V with a 15 pF load. This value is guaranteed over the full –55°C to +125°C temperature range and reflects the device's ability to reliably capture data on each rising clock edge without violating internal timing margins. The 5962-9686001QCA achieves this performance while maintaining sub-5 ns propagation delay and robust noise immunity.

Does the 5962-9686001QCA require external pull-up or pull-down resistors on unused inputs?

Yes, all unused inputs of the 5962-9686001QCA must be held at VCC or GND to ensure proper device operation and prevent floating nodes from inducing excessive current or unpredictable logic states. This requirement is explicitly stated in TI's recommended operating conditions and applies to both PRE and CLR inputs when not actively used. The 5962-9686001QCA does not include internal weak pull-ups or pull-downs, so external termination is mandatory for reliability.

How does the 5962-9686001QCA handle simultaneous assertion of PRE and CLR inputs?

When both PRE and CLR are asserted low simultaneously, the 5962-9686001QCA enters an unstable output state (Q = Q̅ = H), which is explicitly documented as non-persistent in the function table. Upon release of either PRE or CLR, the outputs resolve to a valid complementary state based on the remaining active control signal. This behavior is inherent to the internal gate structure and is consistent across all AHC74 variants, including the 5962-9686001QCA.

Is the 5962-9686001QCA compliant with RoHS or other environmental directives?

The 5962-9686001QCA is a military-specification device manufactured under QML-38535 and is not subject to commercial RoHS requirements. Its CDIP package uses leaded solder and ceramic/glass frit materials compatible with traditional military assembly processes. TI's packaging addendum confirms "Call TI" for lead finish details, indicating non-RoHS-compliant construction appropriate for high-reliability, exempted applications per EU Directive Annex III.

Can the 5962-9686001QCA operate reliably at 2 V supply voltage?

Yes, the 5962-9686001QCA is fully specified to operate from 2 V to 5.5 V, with guaranteed timing and DC parameters across this range. At 2 V, it delivers 80 MHz maximum frequency (CL = 15 pF), 7.6 ns propagation delay, and maintains rail-to-rail output swing. This low-voltage capability enables integration into battery-backed subsystems and mixed-signal boards where power efficiency and compatibility with 2.5 V or 3.3 V domains are essential - all while retaining its –55°C to +125°C rating and military qualification.
