Product details
Overview
CD74HCT153M96 from Texas Instruments is a dual 4-to-1-line selector/multiplexer IC with common select inputs (S0, S1), independent enable inputs (1E, 2E), and CMOS/TTL-compatible logic levels. It operates from 4.5 V to 5.5 V, delivers propagation delays as low as 24 ns (I→Y, CL = 50 pF), and supports industrial temperature range (–55 °C to +125 °C). It is used in digital signal routing, address decoding, and data path selection in embedded control systems.
For engineers reviewing the CD74HCT153M96 datasheet, CD74HCT153M96 pinout, CD74HCT153M96 application, or CD74HCT153M96 equivalent, key selection criteria include LSTTL input compatibility (VIL ≤ 0.8 V, VIH ≥ 2.0 V), SOIC-16 package constraints, dual-section independent enable control, and guaranteed operation across –55 °C to +125 °C without derating.
Technical Context
The CD74HCT153M96 implements two independent 4:1 multiplexers sharing S0/S1 select lines but featuring separate 1E/2E enables - enabling selective activation of either section without affecting the other. Each output (1Y, 2Y) is actively driven LOW when its corresponding enable is HIGH, and enters high-impedance state only when disabled.
Its HCT logic family ensures direct interface with legacy LSTTL outputs while maintaining CMOS power efficiency: input leakage ≤ ±1 µA, quiescent ICC ≤ 160 µA over full temperature range, and noise immunity of 30% of VCC at 5 V. Propagation delay symmetry (tPLH ≈ tPHL) and balanced transition times support clean timing in synchronous digital systems.

Pinout & Package
CD74HCT153M96 uses a 16-pin SOIC (Small Outline Integrated Circuit) package with standard 1.27 mm pitch and 3.9 mm body width. Pin 1 is located in Quadrant Q1 per tape orientation standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1E | Section 1 Enable Input | Active-HIGH enable: drives 1Y LOW when HIGH; disables 1Y (high-Z) when LOW |
| S1, S0 | Common Select Inputs | Binary-select lines shared by both multiplexers; determine which of I0–I3 is routed to Y |
| 1I0–1I3 | Section 1 Data Inputs | Four independent digital inputs for first 4:1 mux; selected based on S1/S0 state |
| 1Y | Section 1 Output | Active-LOW output: reflects selected input when 1E = HIGH; high-impedance when 1E = LOW |
| GND (Pin 8) | Ground Reference | Primary return path for all internal logic and I/O; must be low-impedance connection |
| VCC (Pin 16) | Power Supply | 4.5–5.5 V CMOS supply; bypassing with 0.1 µF ceramic capacitor near pin required |
| 2I0–2I3 | Section 2 Data Inputs | Four independent digital inputs for second 4:1 mux; shares S1/S0 with Section 1 |
| 2Y | Section 2 Output | Active-LOW output: mirrors 1Y behavior but controlled independently by 2E |
| 2E | Section 2 Enable Input | Active-HIGH enable for second section; fully decoupled from 1E for independent control |
Key Features
| Feature | Design Value |
|---|---|
| Direct LSTTL input compatibility | VIL ≤ 0.8 V / VIH ≥ 2.0 V allows seamless integration into legacy 5 V TTL systems without level shifters |
| Independent dual-section enables | 1E and 2E allow time-multiplexed or conditional routing of two data streams using shared select lines |
| Balanced propagation delay | tPLH and tPHL match within 10% - minimizes skew in critical timing paths and reduces setup/hold violations |
| High noise immunity | NIL/NIL = 30% of VCC at 5 V - suppresses false triggering in electrically noisy industrial environments |
| Wide temperature operation | –55 °C to +125 °C rating enables use in uncontrolled enclosures, avionics, and engine-control modules |
Applications
| Industrial PLC I/O Expansion | Automotive Body Control Module |

Use Scenario: Routing sensor inputs (door lock status, window position, mirror fold signals) to a single microcontroller ADC or GPIO port. IC Role / Device Role / Timing Role: Dual 4:1 multiplexer selects among eight discrete inputs using shared S0/S1 and independent 1E/2E to isolate functional domains. Use Value: Reduces MCU pin count by 6 while preserving real-time responsiveness - propagation delay <25 ns ensures no measurable latency in safety-critical feedback loops. |
Use Scenario: Consolidating switch matrix signals (headlight mode, wiper speed, HVAC fan settings) onto a CAN node controller with limited GPIO. IC Role / Device Role / Timing Role: Acts as a digital signal concentrator; enables/disables each 4-input group via dedicated E pins synchronized to vehicle power modes. Use Value: Enables hot-swap-safe input gating - disabled sections present high-Z, eliminating backfeed during module replacement or sleep/wake transitions. |

IC Role / Device Role / Timing Role: Ruggedized signal router operating across –55 °C to +125 °C; enabled only during active monitoring cycles to minimize power draw. Use Value: Meets MIL-PRF-38535 Class K requirements via CD54HCT153 lineage; SOIC-16 package supports conformal coating and thermal cycling reliability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4:1 multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HCT153DR | Same HCT logic, identical pinout, but rated only for –40 °C to +85 °C; lower max ICC (100 µA typical) | Not suitable for extended temperature deployments; acceptable for commercial-grade instrumentation | Select SN74HCT153DR only if ambient operating range stays within industrial grade limits and cost sensitivity outweighs temp margin. |
| CD74HC153M96 | HC variant: 2–6 V operation, VIH/VIL referenced to VCC (not fixed TTL thresholds); higher propagation delay (29 ns min) | Requires level-shifting for legacy TTL systems; better for mixed-voltage battery-powered designs | Choose CD74HC153M96 when supply flexibility (e.g., 3.3 V or 5 V) and ultra-low static current (<8 µA typ) are prioritized over TTL compatibility. |
Compared with SN74HCT153DR, CD74HCT153M96 provides extended temperature resilience and higher noise immunity; compared with CD74HC153M96, it ensures drop-in compatibility with existing 5 V TTL infrastructure without redesigning input drive stages.

FAQ
What is the maximum supply voltage for CD74HCT153M96?
The absolute maximum DC supply voltage for CD74HCT153M96 is 7 V, but operational specification requires 4.5 V to 5.5 V. Operating outside this range risks violating input threshold definitions, increasing ICC, and compromising noise margins. Always maintain VCC within 4.5–5.5 V for guaranteed compliance with VIH/VIL and propagation delay specs in the CD74HCT153M96 datasheet.
Does CD74HCT153M96 support 3.3 V logic inputs?
No - CD74HCT153M96 is an HCT device with fixed TTL-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V), not VCC-referenced. A 3.3 V logic HIGH may fall below the 2.0 V minimum VIH requirement depending on source impedance and noise, risking unreliable recognition. For 3.3 V systems, use CD74HC153M96 or add a level translator.
How does the enable logic work on CD74HCT153M96?
Each section (1 and 2) has its own active-HIGH enable (1E, 2E). When 1E = HIGH, 1Y outputs the selected input (per S0/S1); when 1E = LOW, 1Y goes to high-impedance (not LOW). This differs from some muxes with active-LOW enables. The same applies to 2E/2Y. Both sections share S0/S1 but operate independently.
Is CD74HCT153M96 pin-compatible with CD74HC153M96?
Yes - CD74HCT153M96 and CD74HC153M96 share identical SOIC-16 pinout, footprint, and terminal functions. However, they differ in electrical behavior: HCT guarantees TTL input compatibility and tighter VIH/VIL tolerances, while HC offers wider VCC range (2–6 V) and VCC-referenced thresholds. Swapping requires verifying input drive strength and voltage levels.
What is the meaning of "M96" in CD74HCT153M96?
The "M96" suffix denotes a 16-pin SOIC package supplied in large tape-and-reel format (2500 units per reel), with MSL Level-1 rating and NIPDAU lead finish. It is functionally identical to CD74HCT153M but optimized for automated SMT assembly. The "M" alone indicates SOIC packaging; "96" specifies the packaging configuration per TI's ordering nomenclature.
