Product details

Overview

7601001EA from National Semiconductor is a TTL-compatible 8-to-1 data selector/multiplexer with complementary Y (true) and W (inverted) outputs, 12.5 ns typical propagation delay from data input to W output, 30 mW typical power dissipation, and operation across 4.5–5.5 V supply. It enables parallel-to-serial conversion in digital logic systems such as address decoding and Boolean function generation.

For engineers reviewing the 7601001EA datasheet, 7601001EA pinout, 7601001EA application, or 7601001EA equivalent, key selection criteria include strobe-enabled enable logic, dual complementary outputs, guaranteed operation over military (–55°C to +125°C) or commercial (0°C to +70°C) temperature ranges, and compatibility with standard LS-TTL signal levels.

Technical Context

The 7601001EA implements full on-chip 3-bit binary decoding for eight data inputs (D0–D7), controlled by select lines A, B, and C. Its active-low strobe (S) disables both outputs when high - forcing Y low and W high - and enables normal multiplexing only when S is low.

It features complementary outputs with distinct timing: propagation delays to Y range from 26–46 ns depending on input source and load, while delays to W are faster (20–40 ns). Output drive capability meets LS-TTL standards: I_OL ≥ 4 mA (DM74LS) or 8 mA (DM54LS), and I_OH ≤ –0.4 mA.

10	S (Strobe)	Active-low enable - forces Y=L, W=H when high; enables multiplexing only when low
11	A	Select line A - LSB of 3-bit binary address for input selection
12	B	Select line B - middle bit of 3-bit binary address
13	C	Select line C - MSB of 3-bit binary address

Equivalent & Alternatives

The following parts are listed as comparable options for similar data selector/multiplexer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LS151N	Same logic function, identical pinout, commercial temp range (0°C to +70°C); no military-grade screening	Limited to non-aerospace industrial or lab use; lower cost and wider distributor availability	Preferred for cost-sensitive commercial designs where extended temperature operation is not required
MC74HC151N	CMOS version; higher noise immunity, wider V_CC range (2–6 V), but slower max speed (~30 ns typ @ 4.5 V) and different input thresholds	Requires level-shifting when interfacing with legacy LS-TTL; unsuitable for direct replacement in existing 5 V LS systems	Recommended only for new CMOS-based designs prioritizing power efficiency over raw speed or TTL compatibility

Compared with SN74LS151N and MC74HC151N, the 7601001EA offers guaranteed operation across –55°C to +125°C, full LS-TTL compatibility without interface components, and faster D→W propagation (21 ns min), making it optimal for ruggedized or legacy-matched systems.

FAQ

What is the operating temperature range for the 7601001EA?

The 7601001EA is rated for operation from –55°C to +125°C, consistent with the DM54LS military-grade specification. This range is validated per National Semiconductor's recommended operating conditions and absolute maximum ratings, supporting deployment in harsh-environment applications such as airborne computing and downhole instrumentation where thermal cycling exceeds commercial limits.

Does the 7601001EA have complementary outputs, and how are they used?

Yes, the 7601001EA provides complementary Y (true) and W (inverted) outputs. When enabled (strobe low), Y reflects the selected D-input value while W delivers its logical inverse - eliminating the need for an external inverter in circuits requiring both signal polarities, such as differential bus drivers or dual-rail logic interfaces. This feature is explicitly confirmed in the General Description and Truth Table sections of the datasheet.

What is the propagation delay from data input to W output for the 7601001EA?

The 7601001EA exhibits a typical low-to-high propagation delay of 21 ns and high-to-low delay of 20 ns from any D-input (D0–D7) to the W output, measured at V_CC = 5 V and T_A = 25°C with C_L = 15 pF. These values are specified in the Switching Characteristics table and represent worst-case performance under standard test conditions.

Is the 7601001EA pin-compatible with other 74LS151 variants?

Yes, the 7601001EA uses the same 16-pin DIP footprint and pin assignment as DM54LS151J and DM74LS151N, per NS package number J16A. All share identical pin functions including D0–D7, A/B/C selects, strobe (S), Y/W outputs, V_CC, and GND - enabling drop-in substitution within the same package type and temperature grade.

What is the maximum supply voltage the 7601001EA can tolerate?

The 7601001EA has an absolute maximum supply voltage rating of 7 V, as stated in the Absolute Maximum Ratings table. However, reliable operation is only guaranteed within the recommended range of 4.5–5.5 V for DM54LS versions. Exceeding 5.5 V risks parametric shift or accelerated degradation, even if below the 7 V absolute limit.
