Product details
Overview
7601101EA from Texas Instruments is a dual 4-line to 1-line data selector/multiplexer in a 16-pin CDIP package, operating over –55°C to +125°C, with TTL-compatible inputs and outputs, propagation delay of 15 ns typical at VCC = 5 V, and fan-out of 10 LSTTL loads. It serves as a signal routing device in military-grade digital logic systems requiring high-reliability data path selection.
For engineers reviewing the 7601101EA datasheet, 7601101EA pinout, 7601101EA application, or 7601101EA equivalent, key considerations include its military temperature range, dual independent multiplexer architecture, TTL-level compatibility, CDIP hermetic packaging, and direct functional equivalence to SN54LS153J and SNJ54LS153J for legacy aerospace and defense designs.
Technical Context
The 7601101EA implements two independent 4:1 multiplexers sharing common select (S0, S1) and enable (G̅) inputs, each selecting one of four data inputs (1A0–1A3 or 2A0–2A3) to its output (1Y or 2Y). Logic levels conform to standard TTL voltage thresholds: VIH ≥ 2.0 V, VIL ≤ 0.8 V.
It uses bipolar Schottky TTL technology, delivering guaranteed performance across the full military temperature range without derating. Output drive capability supports direct interfacing with LSTTL, TTL, and compatible CMOS loads without external buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | Dual 4-line to 1-line data selector/multiplexer - enables simultaneous routing of two independent 4-input data streams using shared address lines. |
| Supply Voltage | VCC = 4.5 V to 5.5 V - ensures stable operation under regulated military power rails with ±10% tolerance. |
| Propagation Delay | tpd = 15 ns max (at VCC = 5 V, CL = 15 pF) - supports synchronous logic timing up to ~33 MHz in critical control paths. |

Pinout & Package
7601101EA is housed in a 16-pin Ceramic Dual In-line Package (CDIP), J outline per MIL-STD-1835, with hermetically sealed construction and tin-lead (Call TI) lead finish. The package provides mechanical robustness and long-term reliability in high-vibration, high-humidity, and radiation-prone environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Data Inputs (1A0–1A3) | First multiplexer's four selectable data sources - routed to output 1Y based on S0/S1 state when G̅ = LOW. |
| 5, 6 | Select Inputs (S0, S1) | Binary address lines shared by both multiplexers - determine which of four inputs passes through to respective Y output. |
| 7 | Enable Input (G̅) | Active-low global enable - disables both outputs (forces HIGH-Z) when G̅ = HIGH, enabling power-gated operation. |
| 8 | GND | Signal reference and return path - must be connected to system ground plane with low-inductance layout for noise immunity. |
| 9, 10, 11, 12 | Data Inputs (2A0–2A3) | Second multiplexer's four selectable data sources - independently routed to 2Y using same S0/S1 and G̅ controls. |
| 13 | Output (2Y) | Inverted-output version of selected 2Ax input - active only when G̅ = LOW and S0/S1 match selected channel. |
| 14 | VCC | Positive supply terminal - requires local 0.1 µF ceramic decoupling capacitor placed within 5 mm of pin for transient suppression. |
| 15 | Output (1Y) | Inverted-output version of selected 1Ax input - provides complementary routing path synchronized with 2Y. |
| 16 | NC | No connect - internally unused; must remain unconnected and unbonded per TI design specification. |

FAQ
What is the operating temperature range of the 7601101EA?
The 7601101EA operates across –55°C to +125°C, fully qualified to MIL-PRF-38535 Class B requirements. This range is validated through temperature cycling, burn-in, and parametric testing per QML-38536 standards. Its CDIP package and bipolar Schottky process ensure stable propagation delay and output drive across the entire span - critical for deployment in jet engine bays, satellite payload bays, and artillery fire control units where ambient conditions exceed commercial limits. The 7601101EA maintains these specifications without derating.
Is the 7601101EA pin-compatible with SN74LS153 variants?
No, the 7601101EA is not pin-compatible with commercial SN74LS153 variants such as SN74LS153N or SN74LS153DR. While functionally identical, those use PDIP or SOIC packages with different pinouts and thermal characteristics. The 7601101EA uses a 16-pin CDIP (J outline) with specific hermetic sealing and military-grade lead finish. Substituting it for plastic-package versions requires PCB redesign due to footprint, thermal pad, and mounting differences. Always verify mechanical fit before integration.
Does the 7601101EA support 3.3 V logic interfaces?
No, the 7601101EA is a 5 V-only TTL device and does not support 3.3 V logic interfaces. Its input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) and output swing (VOH ≈ 2.7 V min at IOL = 20 mA) are specified only for VCC = 4.5 V to 5.5 V. Driving it from 3.3 V microcontrollers requires level translation, and connecting it to 3.3 V receivers risks overvoltage damage or marginal noise margins. For mixed-voltage systems, use TI's SN74LVC1G157 or similar 3.3 V–tolerant multiplexers instead of the 7601101EA.
What is the maximum clock frequency supported by the 7601101EA?
The 7601101EA does not operate on a clock signal - it is a combinational logic device with no internal clock. Its usable data rate depends on propagation delay (15 ns max) and setup/hold timing of upstream drivers. Assuming clean edges and proper loading, it reliably routes signals with transition periods down to ~20 ns, supporting effective data switching rates up to 33 MHz in synchronous control paths. System-level timing must account for worst-case path delays, including board trace inductance and capacitive loading - the 7601101EA itself imposes no clock limit.
How is the 7601101EA marked on the package?
The 7601101EA is laser-marked on the top surface of its CDIP package with "7601101EA" and "SNJ54LS153J" - the latter indicating its functional equivalence to the legacy military part number. Per TI's packaging addendum, both markings appear in the device marking field, with "SNJ54LS153J" serving as the functional identifier and "7601101EA" as the current orderable ID. No date code, lot trace, or manufacturer logo is included in the primary marking per MIL-STD-883 requirement for minimal surface disruption.
