Product details
Overview
7601901EA from Texas Instruments is a quad 2-input multiplexer with TTL-compatible inputs and outputs, configured as two independent 4-to-1 data selectors in a single 16-pin CDIP package, operating across -55°C to +125°C, and used in military-grade digital logic routing and signal path selection.
For engineers reviewing the 7601901EA datasheet, 7601901EA pinout, 7601901EA application, or 7601901EA equivalent, key selection considerations include its extended temperature range, dual-mux architecture, TTL-level compatibility, and CDIP hermetic packaging for high-reliability systems.
Technical Context
The 7601901EA implements two independent 4-to-1 multiplexers sharing common select lines (S0, S1) and an output enable (OE), supporting simultaneous or independent channel selection. Each mux accepts four digital inputs (I0–I3) and routes one to its output (Y) based on binary select code.
It uses bipolar TTL circuitry with guaranteed propagation delays ≤25 ns (max) at VCC = 5V, input thresholds aligned to standard TTL logic levels (VIH ≥ 2.0V, VIL ≤ 0.8V), and operates without external biasing or level-shifting in legacy 5V digital systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Operating Temperature | -55°C to +125°C - qualified for military and aerospace environments |
| Propagation Delay | ≤25 ns (max) - ensures timing predictability in synchronous logic designs |
| Input Logic Levels | VIH ≥ 2.0V, VIL ≤ 0.8V - interoperable with standard TTL and LS-family devices |
| Output Drive | IOL = 24 mA, IOH = -0.4 mA - sufficient to drive multiple TTL inputs directly |
Pinout & Package
7601901EA is housed in a 16-pin Ceramic Dual In-line Package (CDIP) with hermetic sealing, suitable for high-reliability applications requiring moisture resistance and thermal stability.
| Pin/Terminal | Circuit Role | Design Meaning |

| 7 | Output enable OE | Active-low enable; disables both outputs when high |
| 8 | GND | Power reference ground terminal |
| 9 | Y1 output | Selected output from first multiplexer (pins 1–4) |
| 10, 11, 12, 13 | MUX B inputs I0–I3 | Four data inputs for second multiplexer; routed to Y2 |
| 14 | Y2 output | Selected output from second multiplexer (pins 10–13) |
| 15 | VCC | +5V supply terminal |
| 16 | NC | No internal connection - left unconnected per TI datasheet |

FAQ
What is the operating temperature range of the 7601901EA?
The 7601901EA operates from -55°C to +125°C, meeting military environmental specifications. This range is validated per TI's qualified version documentation for SN54LS298-class devices and is enabled by its CDIP hermetic package and bipolar TTL process. The 7601901EA maintains full functionality across this entire span without derating.
Is the 7601901EA pin-compatible with SN54LS298J?
Yes, the 7601901EA is pin-compatible with SN54LS298J: both use the CDIP-16 (J) package with identical pin assignments, electrical characteristics, and functional behavior. TI's packaging addendum confirms identical package drawing J, 16 pins, and shared device marking conventions - making them mechanically and electrically interchangeable.
Does the 7601901EA require external pull-up resistors on its outputs?
No, the 7601901EA does not require external pull-up resistors. Its outputs are active-drive TTL-compatible, capable of sourcing -0.4 mA and sinking 24 mA. This allows direct interfacing with standard TTL inputs without additional components, as confirmed by TI's SN54LS298 family datasheet and DC characteristics table.
What is the maximum propagation delay for the 7601901EA at 5V supply?
The maximum propagation delay for the 7601901EA is 25 ns at VCC = 5V, measured from select/input transition to valid output change under specified load conditions. This value is consistent across both multiplexer sections and is guaranteed over the full -55°C to +125°C operating range per TI's military-grade characterization.
Can the 7601901EA be used in place of SN74LS298N in commercial designs?
No - the 7601901EA is not a drop-in replacement for SN74LS298N due to fundamental differences in temperature range (-55°C to +125°C vs. 0°C to +70°C) and packaging (hermetic CDIP vs. plastic PDIP). While logic function matches, thermal and mechanical compatibility must be verified per application requirements before substitution.
