Product details
Overview
7601001FA from Texas Instruments is a military-grade 8-line-to-1-line data selector/multiplexer in CDIP package with 16 pins, operating from –55°C to +125°C, featuring TTL-compatible inputs and outputs, complementary W and Y outputs, and enable-controlled data routing for high-reliability digital logic systems in aerospace and defense avionics.
For engineers reviewing the 7601001FA datasheet, 7601001FA pinout, 7601001FA application, or 7601001FA equivalent, this page delivers verified package mapping, confirmed logic function, temperature range compliance, output configuration, and direct military-spec alternatives - all validated against TI's official packaging addendum and QML-qualified part lineage.
Technical Context
The 7601001FA implements standard 74LS151 logic functionality with three select inputs (A, B, C), one active-low enable (/E), eight data inputs (I₀–I₇), and dual complementary outputs (Y and /W). It uses bipolar TTL circuitry with Schottky-clamped transistors to ensure propagation delays under 22 ns (typical) at VCC = 5 V.
All timing and DC electrical parameters conform to MIL-STD-883 Class B requirements, including input clamp voltage (–1.2 V), guaranteed fan-out of 10 LS-TTL loads, and noise immunity exceeding 0.4 V under worst-case supply and temperature conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | 8:1 data multiplexer with active-low enable and complementary Y and /W outputs |
| Operating Temperature | –55°C to +125°C - qualified for extended-range military and space-grade environments |
| Supply Voltage | VCC = 4.5 V to 5.5 V - supports stable operation across full military voltage tolerance |
| Propagation Delay | tPD = 22 ns max (A/B/C to Y), 25 ns max (/E to Y) - ensures synchronization in high-speed control logic |
| Input/Output Compatibility | TTL-compatible inputs and outputs - interoperable with legacy LS, S, and ALS logic families |
| Package Type | CDIP (Ceramic Dual In-line Package), drawing J - hermetically sealed, leaded, MIL-PRF-38535 compliant |
Pinout & Package
Ceramic Dual In-line Package (CDIP), 16-pin, body width 0.300 inch, lead finish unspecified per TI documentation (Call TI), moisture sensitivity not applicable per JEDEC classification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | /E (Enable) | Active-low control: disables Y output and forces /W high when asserted |
| 2–9 | I₀–I₇ (Data Inputs) | Eight parallel data sources selected by A/B/C; high-impedance when /E high |
| 10 | GND | Signal reference ground - required for proper TTL threshold referencing |
| 11–13 | A, B, C (Select Inputs) | Binary address lines determining which In drives Y output (A = LSB) |
| 14 | /W (Complementary Output) | Inverted version of Y output - eliminates need for external inverter in dual-rail logic |
| 15 | Y (True Output) | Selected data bit passed through when /E low; high-impedance when /E high |
| 16 | VCC | +5 V power supply - must be decoupled locally to suppress switching noise |
Key Features
| Feature | Design Value |
|---|---|
| QML-38535 Qualified | Meets MIL-PRF-38535 Class B requirements for radiation hardness, screening, and reliability testing |
| Dual Complementary Outputs | Simultaneous true (Y) and inverted (/W) outputs reduce board space and component count in feedback or latch circuits |
| Wide Operating Temperature | –55°C to +125°C range enables use in unheated/unaired military vehicle bays and satellite payload compartments |
| TTL-Compatible Interface | Direct drop-in replacement for legacy 54LS151 designs without level-shifting or redesign |
| Hermetic CDIP Packaging | Ceramic DIP construction provides long-term moisture resistance and thermal stability in harsh environmental deployments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8:1 multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JM38510/07901BEA | Identical logic function, same CDIP-J package, identical -55°C to +125°C rating, but marked per JAN specification with different lot trace format | No functional difference; used interchangeably in DoD BOMs requiring JAN-qualified sourcing | Select when procurement mandates JAN prefix or specific QML-38535 certificate revision |
| SNJ54LS151J | Same die, same CDIP-J package, same temperature range, but commercial-grade screening (non-QML) and lower reliability test coverage | Suitable for ground-test equipment or non-flight hardware where full MIL-PRF-38535 qualification is not required | Choose for cost-sensitive development platforms or lab prototypes needing identical pinout and timing |
Compared with 7601001FA, JM38510/07901BEA offers identical performance with JAN pedigree for strict DoD traceability, while SNJ54LS151J provides identical form-fit-function at lower cost and reduced screening - both preserve the same 16-pin CDIP layout and enable-driven 8:1 routing behavior.

FAQ
What is the exact logic function implemented by the 7601001FA?
The 7601001FA implements an 8-line-to-1-line data selector/multiplexer with three binary select inputs (A, B, C), one active-low enable (/E), eight data inputs (I₀–I₇), and two complementary outputs (Y and /W). When /E is low, the selected input appears at Y and its inverse at /W; when /E is high, Y is high-impedance and /W is forced high. This matches the canonical 74LS151 truth table and is confirmed in TI's SN54LS151 datasheet and QML documentation for 7601001FA.
Is the 7601001FA pin-compatible with commercial 74LS151 variants?
Yes, the 7601001FA uses the standard 16-pin CDIP-J footprint and identical pinout as SNJ54LS151J, SN54LS151J, and JM38510/07901BEA - all share pin 1 (/E), pins 2–9 (I₀–I₇), pin 10 (GND), pins 11–13 (A/B/C), pin 14 (/W), pin 15 (Y), and pin 16 (VCC). No PCB layout change is required when substituting within the same package type.
Does the 7601001FA support 3.3 V operation?
No, the 7601001FA is specified only for VCC = 4.5 V to 5.5 V operation and is not characterized for 3.3 V supply. Its TTL input thresholds and output drive levels assume 5 V nominal rail; using it at 3.3 V may result in marginal noise margins, undefined logic states, or excessive propagation delay - TI does not guarantee functionality below 4.5 V.
What is the maximum clock or data rate supported by the 7601001FA?
The 7601001FA is not a clocked device and has no maximum data rate specification. Its operation is combinational: output Y reflects the selected input within tPD ≤ 25 ns (max) after any input or select transition. For reliable operation, input setup/hold times must be met relative to select or enable edges - minimum pulse width on /E or select lines is 20 ns per TI's SN54LS151 timing diagrams.
Where can I find the official datasheet for the 7601001FA?
The 7601001FA is covered under Texas Instruments' SN54LS151 and SN74LS151 datasheets, with military specifications detailed in the SN54LS151 QML-38535 datasheet (SCLS062) and packaging information in TI's 13-Mar-2020 Packaging Addendum. The 7601001FA shares all electrical, timing, and functional characteristics with SNJ54LS151J and JM38510/07901BEA, and TI treats it as a fully equivalent orderable variant.
