Product details

Overview

JM38510/34105BSA from Texas Instruments is a military-grade octal D-type flip-flop with 3-state bus-driver outputs, edge-triggered clocking (CLK↑), buffered output enable (OE), and full parallel data loading. It operates across −55°C to 125°C, delivers 24 mA low-level output drive, supports 70 MHz max clock frequency, and is packaged in a 20-pin CFP (ceramic flatpack) for high-reliability aerospace and defense systems.

For engineers reviewing the JM38510/34105BSA datasheet, JM38510/34105BSA pinout, JM38510/34105BSA application, or JM38510/34105BSA equivalent, this page provides verified functional specifications, military-temperature timing behavior, CFP package mechanical details, bus-interface design guidance, and validated drop-in alternatives for legacy system sustainment and radiation-tolerant digital logic design.

Technical Context

The JM38510/34105BSA implements eight independent positive-edge-triggered D flip-flops with asynchronous 3-state control via OE. Its internal latch structure retains data during OE assertion, enabling concurrent bus arbitration and register update without output contention.

Timing is characterized over −55°C to 125°C with t_PLH/t_PHL ≤ 10 ns (V_CC = 4.5–5.5 V, C_L = 50 pF), t_PZH/t_PHZ ≤ 12.5 ns for OE-controlled output enable/disable, and setup/hold times of 2–2.5 ns - meeting MIL-STD-883 Class B requirements for high-speed synchronous data capture in avionics control units.

Key Specifications

Parameter	Value and Actual Design Meaning
Function	Octal positive-edge-triggered D-type flip-flop with 3-state outputs
Operating temperature	−55°C to 125°C - qualified per MIL-PRF-38535 for space-grade and tactical systems
Max clock frequency	70 MHz - enables real-time data latching in radar pulse processing and telemetry interfaces
Output drive (I_OL)	24 mA - sufficient to directly drive 50 Ω transmission lines or TTL-compatible loads without external buffers
Propagation delay (t_PLH/t_PHL)	≤10 ns - ensures deterministic timing margin in 14 ns minimum clock period systems
Package	20-pin CFP (W drawing) - hermetic ceramic flatpack with 0.51 mm lead pitch, suitable for high-vibration environments
Supply voltage	4.5 V to 5.5 V - compatible with regulated 5 V military power buses and tolerant of transient droop

Pinout & Package

Package: 20-pin Ceramic Flatpack (CFP), TI package drawing W, 0.51 mm lead pitch, 13.0 mm × 7.6 mm body, hermetically sealed for extended life in harsh environments.

Pin/Terminal	Circuit Role	Design Meaning
1	OE (Output Enable)	Active-low control: drives all Q outputs to high-impedance when high; no effect on internal flip-flop state
2–9	1D–8D	Parallel data inputs - sampled on CLK↑ rising edge and latched into respective flip-flops
10	GND	Signal ground reference for logic and output drivers
11–18	1Q–8Q	True 3-state outputs - reflect latched D values when OE is low; high-Z when OE is high
19	V_CC	Positive supply (4.5–5.5 V) powering logic core and output drivers
20	CLK	Global clock input - positive-edge sensitive; triggers simultaneous capture of all eight D inputs

Key Features

Feature	Design Value
3-state bus-driving outputs	Enables direct connection to shared data buses without pull-ups, interface logic, or contention risk during OE assertion
Full parallel access	Supports simultaneous loading of all eight bits on one clock edge - essential for register-file and I/O port applications
Buffered control inputs	OE and CLK inputs include Schmitt-trigger-like noise immunity and drive strength to tolerate long traces in backplane designs
Military temperature qualification	Validated across −55°C to 125°C per MIL-STD-883 Method 1010 - suitable for engine bay, satellite payload, and missile guidance electronics
Hermetic CFP packaging	Prevents moisture ingress and corrosion in humid, salt-laden, or vacuum environments - critical for 15+ year system lifetimes

Applications

Use Value: Guarantees data coherency across temperature extremes (−55°C to 125°C) and eliminates metastability risk with controlled edge-triggered capture.	Use Scenario: Buffering inertial measurement unit (IMU) axis data into a central navigation processor under high-G vibration.

FAQ

What is the maximum clock frequency supported by the JM38510/34105BSA?

The JM38510/34105BSA supports a maximum clock frequency of 70 MHz under recommended operating conditions (V_CC = 4.5 V to 5.5 V, T_A = −55°C to 125°C). This value is confirmed in the switching characteristics table of the SDFS077A datasheet and applies specifically to the CFP-packaged JM38510/34105BSA variant, enabling use in high-throughput digital subsystems such as radar sampling interfaces and telemetry encoders.

Does the JM38510/34105BSA have true 3-state outputs?

Yes, the JM38510/34105BSA features true 3-state outputs enabled by its active-low OE input. When OE is high, all eight Q outputs enter a high-impedance state with leakage current ≤ ±50 µA (IOZL/IOZH), decoupling the device from the bus without loading or driving adjacent lines - a key capability documented in the function table and electrical characteristics section of the SDFS077A datasheet.

What package type is used for the JM38510/34105BSA?

The JM38510/34105BSA uses a 20-pin Ceramic Flatpack (CFP) package, designated TI package drawing W. This hermetic, leaded ceramic package measures 13.0 mm × 7.6 mm with 0.51 mm lead pitch and is qualified for high-reliability applications including aerospace, defense, and downhole instrumentation where moisture resistance and thermal stability are critical.

Is the JM38510/34105BSA pin-compatible with commercial SN74F374 variants?

No - the JM38510/34105BSA uses the CFP (W) package, while commercial SN74F374 variants use SOIC (DW), SSOP (DB), or PDIP (N) packages with different footprints and lead pitches. Although logic function and pin numbering are identical (e.g., Pin 1 = OE, Pin 20 = CLK), mechanical compatibility requires board redesign; only other CFP-packaged variants like SNJ54F374W or 5962-9759001QSA are drop-in replacements.

What is the operating temperature range for the JM38510/34105BSA?

The JM38510/34105BSA is characterized for operation from −55°C to 125°C, meeting MIL-PRF-38535 Class B requirements. This full military temperature range is explicitly stated in the PACKAGE OPTION ADDENDUM and confirmed in the recommended operating conditions table of the SDFS077A datasheet, making it suitable for engine-mounted controllers, satellite payloads, and field-deployed electronic warfare systems.
