Product details
Overview
SN74HC153NS from Texas Instruments is a dual 4-input CMOS multiplexer with independent active-low enable inputs (1E, 2E), shared binary select lines (S0, S1), non-inverting outputs (1Y, 2Y), and operation across 2 V to 6 V supply. It routes one of four data inputs per channel to its output based on select logic, enabling signal routing in digital control and data acquisition systems.
For engineers reviewing the SN74HC153NS datasheet, SN74HC153NS pinout, SN74HC153NS application, or SN74HC153NS equivalent, this page delivers verified functional architecture, validated SO-16 pin mapping, temperature-rated static/dynamic performance, and real-world multiplexing use cases - all aligned to TI's official SN74HC153NS specification.
Technical Context
The SN74HC153NS implements two independent 4:1 multiplexers sharing S0/S1 select lines but featuring separate enable controls (1E, 2E), allowing asynchronous channel gating. Each multiplexer selects one of four inputs (1I0–1I3 or 2I0–2I3) using 2-bit binary encoding and drives a dedicated non-inverting output (1Y or 2Y).
Input clamping diodes permit interface to voltages exceeding VCC when used with current-limiting resistors. The device complies with JEDEC standard JESD7A and supports industrial temperature range (−40 °C to +85 °C) with propagation delays as low as 14 ns at VCC = 6 V and CL = 50 pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | 74HC high-speed CMOS - compatible with TTL input thresholds only via 74HCT variant; SN74HC153NS uses CMOS-level inputs (VIH ≥ 3.15 V at VCC = 4.5 V) |
| Supply Voltage Range | 2.0 V to 6.0 V - enables direct integration into 3.3 V and 5 V logic systems without level translation |
| Propagation Delay (1I→1Y) | 14 ns typical at VCC = 6.0 V, CL = 50 pF - supports ≤35 MHz switching in critical path routing |
| Output Drive Capability | ±4 mA at VCC = 4.5 V - sufficient to drive 10 LSTTL loads or moderate capacitive bus loads |
| Operating Temperature | −40 °C to +85 °C - qualified for industrial-grade embedded control and instrumentation applications |
| Input Clamp Diodes | Integrated - allows safe interfacing to signals up to VCC + 0.5 V using external current-limiting resistors |
Pinout & Package
SN74HC153NS is supplied in a 16-pin plastic small-outline package (SO-16, package code NS), 3.9 mm body width, with 1.27 mm lead pitch and gull-wing leads. Pin 8 is GND; Pin 16 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | 1E, 2E | Active-low enable inputs - disable respective multiplexer output (force LOW) when HIGH |
| 2, 14 | S1, S0 | Common binary select inputs - determine which of four inputs (0–3) is routed to output |
| 3–6 | 1I3–1I0 | Data inputs for multiplexer 1 - ordered LSB-to-MSB (1I0 = LSB, 1I3 = MSB) |
| 7 | 1Y | Non-inverting output for multiplexer 1 - reflects selected 1In with no polarity inversion |
| 9 | 2Y | Non-inverting output for multiplexer 2 - mirrors function of 1Y for second channel |
| 10–13 | 2I0–2I3 | Data inputs for multiplexer 2 - mapped identically to 1I0–1I3 |
| 8 | GND | Ground reference - must be connected to system 0 V plane for stable logic operation |
| 16 | VCC | Positive supply - powers both multiplexers; decoupling capacitor required near pin |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 4:1 multiplexing | Enables simultaneous routing of two separate 4-signal buses using shared select logic - reduces control line count in FPGA I/O expansion |
| Separate active-low enable per channel | Allows time-multiplexed or conditional activation of each multiplexer - essential for power-gated subsystems and dynamic resource allocation |
| CMOS input thresholds with clamp diodes | Permits robust interfacing to overvoltage sources (e.g., sensors, legacy 5 V peripherals) when paired with series resistors - eliminates need for external protection |
| JEDEC JESD7A compliance | Ensures interoperability with industry-standard logic families and test equipment - simplifies qualification in regulated environments |
| Low quiescent ICC (≤160 µA max) | Minimizes standby power in battery-backed or energy-sensitive applications such as portable test equipment and remote monitoring nodes |
Applications
| Industrial PLC I/O Expansion | Digital Test Equipment Signal Routing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4-input multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HCT153NS | TTL-compatible inputs (VIH = 2.0 V min); identical pinout, timing, and package | Better suited for mixed 5 V TTL/CMOS systems where input noise margin or legacy driver compatibility is critical | Select SN74HCT153NS when interfacing directly to 74LS or 74F series outputs without level shifters |
| MC74HC153ADR2G | Identical 74HC logic function; manufactured by ON Semiconductor; same SO-16 package and electrical specs | Valid second-source option with alternate supply chain; minor packaging variation (tape-and-reel vs. tube) | Choose MC74HC153ADR2G for dual-sourcing assurance or volume pricing negotiation leverage |
Compared with SN74HC153NS, SN74HCT153NS offers improved noise immunity with TTL input thresholds but requires 4.5–5.5 V operation, while MC74HC153ADR2G provides identical CMOS performance with alternate logistics - making SN74HC153NS optimal for pure 3.3 V or wide-VCC designs requiring maximum input voltage flexibility.

FAQ
What is the maximum supply voltage rating for SN74HC153NS?
The absolute maximum supply voltage (VCC) for SN74HC153NS is +7.0 V, but recommended operation is limited to 2.0 V to 6.0 V per TI's datasheet. Operating continuously above 6.0 V risks parametric degradation and reduced reliability, even if within absolute maximum limits. Always use decoupling capacitors and observe derating curves for thermal management.
Does SN74HC153NS support 3.3 V logic systems?
Yes, SN74HC153NS is fully specified for 3.3 V operation: VIH = 2.31 V min (70% of 3.3 V), VIL = 0.99 V max (30% of 3.3 V), and propagation delay is 19 ns typical at VCC = 3.3 V. Its wide 2–6 V range makes it ideal for mixed-voltage boards where 3.3 V MCUs control 5 V peripherals via level-tolerant inputs.
How does the enable logic work on SN74HC153NS?
SN74HC153NS features two independent active-low enables: 1E (pin 1) controls multiplexer 1 (1I0–1I3 → 1Y), and 2E (pin 15) controls multiplexer 2 (2I0–2I3 → 2Y). When either enable is HIGH, its corresponding output is forced LOW regardless of select or input states - enabling hardware-based channel blanking or power sequencing.
Can SN74HC153NS be used for analog signal multiplexing?
SN74HC153NS is rated for digital logic-level signals only. While it can pass analog voltages within GND ≤ VIN ≤ VCC with acceptable on-resistance (~80 Ω typical), it lacks rail-to-rail analog bandwidth, guaranteed THD, or off-isolation specs. For precision analog multiplexing, use purpose-built analog switches like TMUX6208 instead of SN74HC153NS.
What package type is SN74HC153NS supplied in?
SN74HC153NS is supplied exclusively in the 16-pin SOIC (small outline integrated circuit) package, designated NS by Texas Instruments - 3.9 mm body width, 1.27 mm lead pitch, gull-wing leads, RoHS-compliant, and compatible with standard SO-16 footprints and reflow profiles.
