Texas Instruments JM38510/30107BFA

Overview

JM38510/30107BFA from Texas Instruments is a military-grade hex D-type flip-flop with asynchronous clear, implemented in TTL-LS logic, packaged in a 16-pin CFP (ceramic flatpack) for high-reliability aerospace and defense systems. It provides six independent edge-triggered D flip-flops, operates over –55°C to +125°C, features typical propagation delay of 25 ns (t_PLH/t_PHL), and draws 34 mA max I_CC at V_CC = 5 V.

For engineers reviewing the JM38510/30107BFA datasheet, JM38510/30107BFA pinout, JM38510/30107BFA application, or JM38510/30107BFA equivalent, this device is selected for radiation-tolerant synchronous logic, flight computer register files, hardened data latching, and legacy MIL-STD-883-compliant digital control subsystems requiring guaranteed operation across extreme temperature and vibration environments.

Technical Context

The JM38510/30107BFA implements six identical D-type flip-flops sharing a common asynchronous active-low CLEAR input and clocked by a single positive-edge-triggered CLK signal. Each stage has true (Q) and complement (Q̅) outputs, with no internal feedback or preset functionality.

It belongs to the SN54LS174 family - a QML-38510 qualified variant of the SN74LS174 - using bipolar Schottky-clamped TTL technology. Its electrical behavior conforms strictly to the SDLS068A specification, including guaranteed fan-out of 10 LS-TTL loads and noise margin ≥0.4 V under worst-case conditions.

FAQ

What is the maximum clock frequency supported by the JM38510/30107BFA?

The JM38510/30107BFA does not specify a maximum clock frequency in its datasheet; instead, timing is defined by minimum pulse widths and propagation delays. With t_PLH/t_PHL ≤ 25 ns and t_W (clock pulse width) ≥ 20 ns, reliable operation is ensured up to approximately 20 MHz in worst-case conditions. The JM38510/30107BFA is intended for deterministic, non-overclocked synchronous logic rather than high-speed data-path applications.

Is the JM38510/30107BFA pin-compatible with commercial SN74LS174 variants?

No - the JM38510/30107BFA uses a 16-pin CFP (Package Drawing W), while commercial SN74LS174 variants use PDIP (N), SOIC (D), or SO (NS) packages with different pinouts and thermal/mechanical characteristics. Although logic function and signal names match, physical layout, lead geometry, and mounting requirements differ. The JM38510/30107BFA is not a drop-in replacement for surface-mount or through-hole commercial versions.

Does the JM38510/30107BFA include Schmitt-trigger inputs for noise immunity?

No - the JM38510/30107BFA uses standard TTL-LS input thresholds (V_IL ≤ 0.8 V, V_IH ≥ 2.0 V) without hysteresis. It relies on clean, slew-controlled clock and data signals per MIL-STD-883 test conditions. External RC filtering or dedicated Schmitt-trigger buffers must be used if interfacing with noisy or slow-rising signals.

Can the CLR̅ input be left unconnected in the JM38510/30107BFA?

No - the CLR̅ input is active-low and internally pulled up only weakly; leaving it floating risks unintended resets due to noise coupling. TI's SDLS068A specification mandates connection to V_CC via a 1–10 kΩ resistor for inactive state, or driven actively to GND when reset is required. This requirement applies rigorously to the JM38510/30107BFA in all deployed configurations.

What is the radiation tolerance specification for the JM38510/30107BFA?

The JM38510/30107BFA is QML-38510 Class B qualified, which includes total ionizing dose (TID) testing per MIL-STD-883 Method 1019, with guaranteed performance up to 100 krad(Si). It is not specified for single-event effects (SEE) such as latchup or upset - those parameters require separate part number suffixes or supplemental test reports. Radiation hardening is inherent to the process and screening, not explicitly rated beyond TID compliance.
