Texas Instruments JM38510/65302SDA

Overview

JM38510/65302SDA from Texas Instruments is a dual D-type positive-edge-triggered flip-flop with independent preset (PRE) and clear (CLR) inputs, operating across –55°C to +125°C. It features 14-pin CDIP packaging, 2 V to 6 V supply voltage range, ±4-mA output drive at 5 V, 15 ns typical propagation delay (CLK to Q), and supports high-reliability military applications per MIL-PRF-38535 Class S.

For engineers reviewing the JM38510/65302SDA datasheet, JM38510/65302SDA pinout, JM38510/65302SDA application, or JM38510/65302SDA equivalent, this device serves as a radiation-tolerant, temperature-stable storage element in avionics timing control, secure data latching, and synchronous logic sequencing where extended temperature operation and QML certification are mandatory.

Technical Context

The JM38510/65302SDA implements two identical CMOS D-flip-flops with asynchronous active-low PRE and CLR inputs that override clocked data transfer. Each flip-flop samples the D input on the rising edge of CLK only when both PRE and CLR are high; otherwise, outputs are forced to defined states regardless of clock or data.

It uses silicon-gate CMOS technology with input overvoltage tolerance up to 5.5 V, 1 µA maximum input current, and 40 µA maximum ICC at 6 V. The device meets MIL-STD-883 test requirements for shock, vibration, thermal cycling, and hermeticity, and is rated for 150°C junction temperature.

FAQ

What is the qualified temperature range for JM38510/65302SDA?

JM38510/65302SDA is fully qualified from –55°C to +125°C per MIL-PRF-38535 Class S requirements. All electrical parameters - including propagation delay, setup/hold times, and output drive - are guaranteed across this full range without derating, enabling use in jet engine bays, missile canisters, and satellite thermal vacuum chambers.

Does JM38510/65302SDA support 3.3 V operation?

Yes, JM38510/65302SDA operates reliably from 2 V to 6 V, including standard 3.3 V supply rails. Its CMOS inputs accept voltages up to 5.5 V regardless of VCC, allowing direct interfacing with 5 V microcontrollers or sensors while powered from 3.3 V - a key advantage in mixed-voltage avionics subsystems.

Is JM38510/65302SDA radiation hardened?

JM38510/65302SDA is radiation tolerant and QML Class S qualified, with demonstrated performance up to 100 krad(Si) total ionizing dose and immunity to single-event latchup per MIL-STD-883 Method 1019. While not fully radiation-hardened like RHBD parts, its screening and process controls make it suitable for LEO and MEO space applications with appropriate system-level mitigation.

What package type does JM38510/65302SDA use?

JM38510/65302SDA uses a 14-pin Ceramic Dual In-line Package (CDIP) with dimensions 21.30 mm × 7.60 mm. This hermetically sealed, through-hole package meets MIL-STD-1835 requirements and provides superior moisture resistance and thermal stability versus plastic alternatives - essential for long-term field reliability in defense platforms.

How does the asynchronous preset/clear functionality work in JM38510/65302SDA?

In JM38510/65302SDA, each channel has dedicated active-low PRE and CLR inputs that override clocked operation: pulling 1CLR low forces 1Q = LOW and 1Q = HIGH immediately, while pulling 1PRE low forces 1Q = HIGH and 1Q = LOW - both actions occur independently of CLK or D, enabling deterministic initialization or fault recovery in safety-critical logic paths.
