Product details
Overview
JM38510/07101BCA from Texas Instruments is a dual D-type positive-edge-triggered flip-flop in a 14-pin ceramic dual in-line package (CDIP), rated for -55°C to +125°C operation, with TTL-compatible inputs and outputs, and designed for high-reliability military logic applications requiring radiation-tolerant timing control.
For engineers reviewing the JM38510/07101BCA datasheet, JM38510/07101BCA pinout, JM38510/07101BCA application, or JM38510/07101BCA equivalent, this device serves as a qualified QML-38510 Class B dual D flip-flop for synchronous data latching, clock distribution, and state storage in avionics, missile guidance, and space-qualified digital systems.
Technical Context
This device implements two independent D-type flip-flops, each with complementary Q and Q̅ outputs, asynchronous Set and Reset inputs active-low, and edge-triggered clock inputs. It operates strictly on positive-going clock transitions and maintains full TTL voltage-level compatibility.
Designed per MIL-STD-883 and qualified to QML-38510 Class B, the JM38510/07101BCA features hermetic ceramic packaging, glass-frit sealed CDIP construction, and guaranteed performance across the full military temperature range without derating.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual D flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54LS74AJ | Same function and pinout; identical CDIP-14 package but qualified to QML-38510 Class S (not Class B); lower screening level | Suitable for non-critical military platforms where full Class B testing is not mandated | Select SNJ54LS74AJ only when Class B qualification is not required by program specification |
| SN54LS74AJ | Commercial-grade version with same logic and pinout; lacks QML-38510 qualification, MIL-STD-883 testing, and extended temperature validation | Limited to ground-based test equipment or non-flight hardware where environmental stress is minimal | Use SN54LS74AJ only for bench validation or prototype development-not for deployed systems |
Compared with SNJ54LS74AJ and SN54LS74AJ, the JM38510/07101BCA delivers verified Class B reliability, guaranteed -55°C to +125°C operation, and hermetic packaging-making it the sole choice for flight-critical, radiation-exposed, or long-duration mission deployments.

JM38510/07101BCA is fully qualified to MIL-PRF-38535 QML-38510 Class B, including conformance to MIL-STD-883 test methods for screening, environmental stress, and electrical verification. This qualification ensures suitability for high-integrity military systems where failure is not an option.
Does JM38510/07101BCA support asynchronous reset functionality?
Yes, JM38510/07101BCA provides independent active-low asynchronous Clear (CLR̅) and Preset (PRE̅) inputs for each of its two D flip-flops. These inputs override clock and data signals, allowing immediate state initialization without waiting for a clock edge.
What is the maximum operating frequency of JM38510/07101BCA?
The maximum operating frequency of JM38510/07101BCA is 20 MHz, derived from its 25 ns maximum propagation delay (tPLH/tPHL) under nominal conditions. This allows reliable use in synchronous digital systems with clock periods ≥50 ns.
Is JM38510/07101BCA pin-compatible with commercial 74LS74 devices?
Yes, JM38510/07101BCA uses the same 14-pin CDIP footprint and identical pinout as SN54LS74AJ and SN74LS74AN, enabling direct PCB replacement in existing designs-provided thermal, radiation, and qualification requirements align.
What packaging type does JM38510/07101BCA use, and why is it significant?
JM38510/07101BCA uses a hermetically sealed ceramic dual in-line package (CDIP) per drawing J, which prevents moisture ingress and ensures long-term reliability in humid, high-vibration, or vacuum environments-critical for aerospace and defense deployments.
