Product details
Overview
8409301FA from Texas Instruments is a dual 4-line to 1-line data selector/multiplexer in CFP (W) package, operating from −55°C to 125°C with 2 V–6 V supply voltage, ±6-mA output drive at 5 V, and typical propagation delay of 26 ns (VCC = 6 V, CL = 50 pF). It enables parallel-to-serial conversion in military-grade digital logic systems.
For engineers reviewing the 8409301FA datasheet, 8409301FA pinout, 8409301FA application, or 8409301FA equivalent, this page delivers verified functional specifications, validated pin assignments, confirmed military temperature range operation, and real-world multiplexing use cases - all grounded in TI's official SCLS112D datasheet and packaging addendum.
Technical Context
The 8409301FA implements two independent 4:1 multiplexer sections, each with dedicated strobe (G) inputs and shared select lines A and B. Its CMOS architecture delivers rail-to-rail output swing, low input current (≤1 µA), and full binary decoding via integrated inverters and AND-OR gates.
It supports cascading via strobe lines for N-line to n-line expansion and operates across extended military temperature range (−55°C to 125°C) with absolute maximum VCC up to 7 V and continuous output current rating of ±35 mA.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4:1 multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54HC153W | Identical electrical specs and CFP (W) package; same marking "8409301FA" per TI addendum | No functional difference; alternate orderable part number for same device | Select SNJ54HC153W if sourcing through legacy military procurement channels requiring QML-38534 compliance documentation |
| 5962-8409301VFA | Same CFP (W) package, −55°C to 125°C rating, and identical logic function; TI-marked as "SNV54HC153W" | Qualified under SMD 5962 series for space-level screening (not radiation-tolerant); requires additional lot traceability | Choose 5962-8409301VFA only when DoD contract mandates SMD 5962-8409301VFA part number and associated test reporting |
Compared with 8409301FA, SNJ54HC153W offers identical performance and form factor with streamlined logistics for existing JANTXV programs, while 5962-8409301VFA adds SMD-level traceability and screening rigor at higher cost and longer lead time - neither is pin-compatible with commercial SN74HC153 variants due to CFP vs SOIC/PDIP package incompatibility.

FAQ
What is the operating temperature range of the 8409301FA?
The 8409301FA is rated for operation from −55°C to 125°C, meeting MIL-PRF-38534 Class V requirements. This range is validated per TI's SCLS112D datasheet and confirmed in the Package Option Addendum, making it suitable for engine bay, avionics bay, and missile seeker applications where thermal extremes occur.
Is the 8409301FA pin-compatible with commercial SN74HC153 variants?
No, the 8409301FA uses a 16-pin Ceramic Flatpack (CFP, W package), whereas commercial SN74HC153 variants use SOIC (D), PDIP (N), TSSOP (PW), or LCCC (FK) packages. Physical dimensions, lead pitch (0.050"), and mounting method differ fundamentally - PCB redesign is required for substitution.
Does the 8409301FA support 3.3 V logic interfaces?
Yes, the 8409301FA operates across 2 V–6 V, including 3.3 V nominal supply. Its VIH and VIL thresholds scale with VCC (e.g., VIH = 2.0 V min at VCC = 3.3 V), ensuring reliable interfacing with 3.3 V microcontrollers and FPGAs without level translation.
What is the maximum output drive capability of the 8409301FA at 5 V?
At VCC = 5 V, the 8409301FA delivers ±6 mA output drive per output (1Y or 2Y), sufficient to drive up to 15 LSTTL loads. This is specified in the "electrical characteristics" table of SCLS112D and confirmed in the device description section.
Can the 8409301FA be used for cascading multiple multiplexer stages?
Yes - the dedicated strobe (G) inputs on Pins 1 and 10 allow controlled cascading: one 8409301FA's outputs can feed another's data inputs, with strobes sequenced to prevent bus contention. The datasheet explicitly states "Strobe (Enable) Line Provided for Cascading (N Lines to n Lines)" as a core function.
