Product details
Overview
CD74AC153M96 from Texas Instruments is a dual 4-line to 1-line data selector/multiplexer in 16-pin SOIC (D) package, operating from 1.5 V to 5.5 V with ±24 mA output drive, balanced propagation delays, and SCR-latchup-resistant CMOS process. It supports industrial temperature range (−40°C to 85°C) and is used in digital logic routing, address decoding, and signal path selection in embedded control systems.
For engineers reviewing the CD74AC153M96 datasheet, CD74AC153M96 pinout, CD74AC153M96 application, or CD74AC153M96 equivalent, key selection criteria include its dual-channel independent strobe (G) inputs, 5 V/3.3 V/1.5 V compatibility, low-power AC logic performance, ESD immunity (>2 kV HBM), and SOIC-16 footprint for board-level integration in space-constrained designs.
Technical Context
The CD74AC153M96 integrates two independent 4:1 multiplexers sharing common address lines A and B but featuring separate active-low strobe inputs (1G and 2G), enabling asynchronous channel enable/disable. Each section decodes binary inputs to select one of four data inputs (C0–C3) to its output (1Y or 2Y) using AND-OR logic with inverters and drivers.
It employs TI's AC CMOS process with balanced noise immunity at 30% of VCC, achieving tPLH/tPHL as low as 3.0 ns at VCC = 5 V and CL = 50 pF. The device meets MIL-STD-883 ESD requirements (±2000 V HBM) and supports fanout to 15 F-series devices due to its ±24 mA drive capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 5.5 V - Enables interoperability across 1.8 V, 3.3 V, and 5 V logic domains without level shifters. |
| Output Drive Current | ±24 mA - Sufficient to directly drive multiple TTL or CMOS loads (fanout ≥15 F devices) without buffers. |
| Propagation Delay (5 V) | 3.0–11.8 ns - Ensures timing-critical applications like address selection meet sub-12 ns setup/hold windows. |
| ESD Rating (HBM) | ±2000 V - Meets industrial-grade handling requirements without external protection circuitry. |
| Operating Temperature | −40°C to +85°C - Qualified for commercial and industrial environments including motor control and instrumentation. |
| Power Dissipation Capacitance | 93 pF - Predicts dynamic power consumption (P = C × V² × f) for accurate thermal and energy budgeting. |
| Input Clamp Current | ±20 mA - Defines safe current limits during overvoltage transients, informing system-level surge design. |
Pinout & Package
CD74AC153M96 is supplied in a 16-pin SOIC (D) package measuring 9.9 mm × 6.0 mm (body: 9.9 mm × 3.9 mm), RoHS-compliant with NIPDAU lead finish and Level-1 MSL rating (260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1G | Active-low strobe input for Channel 1 | Disables 1Y output when high; enables selection only when low - allows independent gating of first multiplexer. |
| B, A | Binary address select inputs (shared) | Common to both channels; define which of C0–C3 routes to 1Y or 2Y (00→C0, 01→C1, etc.). |
| 1C0–1C3 | Data inputs for Channel 1 | Four parallel digital inputs selected by A/B; tolerate voltages from GND to VCC per recommended conditions. |
| 1Y | Output for Channel 1 | Inverted output logic not applied - true-level output reflecting selected Cx input when 1G is low. |
| GND | Ground reference | Must be connected to system ground plane; bypass capacitor (0.1 µF) required adjacent to Pin 8 for noise suppression. |
| 2Y | Output for Channel 2 | Functionally identical to 1Y but controlled by 2G; supports dual-path signal routing without inter-channel crosstalk. |
| 2C0–2C3 | Data inputs for Channel 2 | Independent set of four inputs; enables simultaneous but separate 4:1 selection on second channel. |
| A | Address select A (shared) | Shared with Channel 1; eliminates need for duplicate address generation logic in microcontroller interfaces. |
| 2G | Active-low strobe input for Channel 2 | Enables/disables Channel 2 independently - critical for time-multiplexed bus arbitration or dual-sensor readout. |
| VCC | Positive supply | Accepts 1.5–5.5 V; requires local 0.1 µF ceramic bypass capacitor between Pin 16 and Pin 8 (GND) per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 4:1 multiplexers | Reduces component count vs. two discrete 74AC151s; shared A/B lines cut PCB trace routing and MCU GPIO usage. |
| 1.5 V to 5.5 V operation | Eliminates voltage translation in mixed-supply systems (e.g., 3.3 V MCU controlling 5 V peripherals). |
| ±24 mA output drive | Drives LEDs, relays, or TTL inputs directly - avoids added buffer ICs in I/O expansion modules. |
| SCR-latchup-resistant process | Prevents destructive latch-up under transient overvoltage or hot-swap conditions in industrial backplanes. |
| 2 kV HBM ESD rating | Meets IEC 61000-4-2 pre-compliance for front-panel controls and field-replaceable modules. |
Applications
| Industrial PLC I/O Expansion | Microcontroller Address Decoding |

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 |
|---|---|---|---|
| SN74AC153DR | Same AC logic family, identical pinout and electrical specs; TI's newer production variant with updated packaging and tape-and-reel configuration. | No functional difference; suitable for new designs requiring latest manufacturing traceability and RoHS compliance. | Select SN74AC153DR for green-field designs where long-term availability and modern logistics (e.g., 2500-piece reels) are prioritized. |
| 74VHC153M | Higher VCC max (5.5 V same), but lower drive (±8 mA) and slower propagation (13 ns typical at 5 V); different input threshold behavior. | Limited to low-fanout or low-speed applications; unsuitable where >15 F-device fanout or sub-12 ns timing is required. | Choose 74VHC153M only if cost sensitivity outweighs performance needs and existing VHC-based designs require drop-in replacement. |
Compared with SN74AC153DR and 74VHC153M, CD74AC153M96 delivers superior drive strength and speed while maintaining pin compatibility with legacy AC-family layouts - making it optimal for upgrading industrial control boards without redesigning PCBs or firmware.

FAQ
What is the maximum operating voltage for CD74AC153M96?
The CD74AC153M96 supports a supply voltage range of 1.5 V to 5.5 V. Its absolute maximum rating is 6 V, but sustained operation above 5.5 V risks permanent damage. At 5.5 V, it delivers guaranteed ±24 mA output drive and meets all AC timing specifications across −40°C to +85°C.
Does CD74AC153M96 support independent address selection for each channel?
No - CD74AC153M96 uses shared address inputs A and B for both channels. This design reduces pin count and simplifies control logic, but requires both multiplexers to select the same data input index (e.g., if A/B = 10, both 1Y and 2Y output C2). Independent addressing would require two separate 74AC151 devices.
Can CD74AC153M96 drive standard TTL loads directly?
Yes - CD74AC153M96 provides ±24 mA output drive, exceeding the ±0.4 mA requirement of standard TTL inputs. It can fan out to up to 15 F-series devices, making it suitable for direct interfacing with legacy TTL logic without additional buffers in most industrial control applications.
What is the purpose of the G (strobe) inputs on CD74AC153M96?
The G inputs (1G and 2G) are active-low enables that gate each multiplexer's output. When high, the corresponding Y output is forced low (not high-impedance); when low, the selected Cx input passes through. This allows precise timing control of data routing, such as synchronizing with clock edges or disabling outputs during reset sequences.
Is CD74AC153M96 compatible with 1.8 V logic systems?
Yes - CD74AC153M96 operates down to 1.5 V, making it fully compatible with 1.8 V systems. At VCC = 1.8 V, VIH is 1.44 V and VIL is 0.36 V per datasheet thresholds, ensuring reliable recognition of 1.8 V logic levels. Propagation delay increases to ~227 ns (max), which must be accounted for in timing budgets.
