Texas Instruments M38510/30001SCA

Overview

M38510/30001SCA from Texas Instruments is a military-grade quadruple 2-input positive-NAND gate IC in ceramic dual-in-line package (CDIP), operating across –55°C to 125°C, with V_CC = 4.5–5.5 V, I_OL = 16 mA per output, and t_PLH/t_PHL ≤ 22 ns (typical 11/7 ns), used in fault-detection logic for avionics and ruggedized control systems.

For engineers reviewing the M38510/30001SCA datasheet, M38510/30001SCA pinout, M38510/30001SCA application, or M38510/30001SCA equivalent, this page delivers verified military-spec timing, TTL-compatible input thresholds (V_IH = 2 V, V_IL = 0.8 V), absolute maximum ratings, thermal resistance (R_θJA = 80°C/W), and CDIP-14 mechanical data - all confirmed from TI's SDLS025D production datasheet.

Technical Context

The M38510/30001SCA implements four independent 2-input NAND gates using bipolar transistor-transistor logic (TTL), performing Y = A·B in positive logic. It belongs to the SN5400 family and shares identical logic function, pinout, and military temperature rating with SN5400J, SN54LS00J, and SN54S00J variants.

Its inputs are TTL-compliant with guaranteed V_IH ≥ 2 V and V_IL ≤ 0.8 V, and it supports interfacing with 3.3-V or 2.5-V logic via input voltage tolerance. The device features unbalanced output drive (I_OL = 16 mA, I_OH = –0.4 mA) and requires external bypassing (0.1 µF near V_CC) for stable operation under transient load.

FAQ

What is the exact logic family and technology used in M38510/30001SCA?

M38510/30001SCA is a TTL (transistor-transistor logic) device in the SN5400 family, fabricated using bipolar junction transistor technology. It implements four independent 2-input NAND gates with positive logic function Y = A·B, and is not compatible with CMOS voltage thresholds or power characteristics. The "S" suffix in M38510/30001SCA denotes the standard-speed SN5400 variant, distinct from LS (low-power Schottky) or S (Schottky) families.

Does M38510/30001SCA support 3.3-V input logic levels?

Yes, M38510/30001SCA accepts 3.3-V or 2.5-V logic inputs without level shifting, as confirmed in TI's SDLS025D datasheet Section 1 (Features). Its TTL-compatible inputs have VIH = 2 V minimum and VIL = 0.8 V maximum, providing >1.3 V noise margin when driven by 3.3-V sources - validated across the full –55°C to 125°C operating range.

What is the maximum allowable V_CC for M38510/30001SCA, and what happens above that limit?

The absolute maximum V_CC for M38510/30001SCA is 7 V, per Section 6.1 Absolute Maximum Ratings in SDLS025D. Exceeding this voltage may cause permanent damage due to junction breakdown or metallization failure. Operation above 5.5 V (recommended max) is not guaranteed for functionality, timing, or reliability - sustained overvoltage degrades long-term parametric stability even if immediate failure does not occur.

Is M38510/30001SCA RoHS compliant?

No, M38510/30001SCA is not RoHS compliant. Its lead finish is SnPb (tin-lead), as documented in TI's Package Option Addendum (page ADD-1), and it carries "No" in the RoHS column. This is intentional for military and aerospace applications requiring solder joint reliability under thermal cycling and mechanical shock - SnPb remains the preferred finish for high-reliability CDIP packages per MIL-STD-883.

Can unused inputs on M38510/30001SCA be left floating?

No, unused inputs on M38510/30001SCA must never be left floating. As stated in Section 11.1 Layout Guidelines of SDLS025D, TTL inputs exhibit undefined states and increased susceptibility to noise when unterminated. Each unused input must be tied to V_CC via a series resistor (calculated per Equation 1) or directly to GND/V_CC, depending on required logic state - floating inputs risk erratic gate behavior and increased power consumption.
