Product details
Overview
CD74ACT153M from Texas Instruments is a dual 4-line to 1-line data selector/multiplexer in SOIC-16 package, featuring TTL-compatible inputs, ±24-mA output drive, balanced propagation delays (4.5–22 ns), and operation across –55°C to 125°C. It implements two independent multiplexing sections with shared select lines A/B and individual strobe (G) inputs, used for signal routing in digital logic systems such as address decoding and data path selection.
For engineers reviewing the CD74ACT153M datasheet, CD74ACT153M pinout, CD74ACT153M application, or CD74ACT153M equivalent, key selection considerations include its ACT-family speed-power balance, dual-section independent enable control, 5-V supply compatibility, and MIL-STD-883 qualified ESD robustness (2 kV).
Technical Context
The CD74ACT153M integrates two independent 4:1 multiplexer sections sharing binary select inputs A and B but each with dedicated strobe (G) and data inputs (C0–C3). Each section uses full binary decoding via inverters and drivers feeding AND-OR logic gates to generate the output Y.
Its CMOS ACT process delivers bipolar-equivalent speed (e.g., tPLH/tPHL down to 3.2 ns on G→Y) with significantly lower quiescent current (ICC ≤ 160 µA at 125°C) than legacy F/AS/S families, while maintaining TTL-level input thresholds (VIH = 2 V, VIL = 0.8 V) and SCR-latchup resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | ACT (Advanced CMOS TTL-compatible), enabling direct interface with 74LS/74F without level shifters |
| Supply Voltage | 4.5 V to 5.5 V - supports stable operation across industrial temperature range without regulation margin loss |
| Propagation Delay | 3.2–22 ns - low skew between select (A/B), data (C), and strobe (G) paths ensures synchronous multiplexing |
| Output Drive | ±24 mA - drives 15 F-type loads or 50-Ω transmission lines, eliminating need for external buffers in medium-speed buses |
| Input Compatibility | TTL-voltage compatible (VIH = 2 V, VIL = 0.8 V) - interoperable with legacy 74-series logic without pull-ups or translators |
| ESD Protection | ≥2 kV per MIL-STD-883 Method 3015 - suitable for handling in non-ESD-controlled environments during assembly |
| Operating Temperature | –55°C to 125°C - qualified for aerospace, military, and extended-temperature industrial applications |
Pinout & Package
CD74ACT153M is housed in a 16-pin SOIC (D) package (JEDEC MS-012AC, 7.5 mm × 10.3 mm body, 1.27 mm pitch), RoHS-compliant with NIPDAU lead finish and MSL Level-1 rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1G (Strobe 1) | Active-low enable for first multiplexer section; when high, 1Y is forced low regardless of A/B/C states |
| 2 | B (Select B) | MSB of 2-bit binary select code common to both sections; determines which C-input routes to Y |
| 3 | 1C3 | Data input 3 for section 1; selected when A=1, B=1 |
| 4 | 1C2 | Data input 2 for section 1; selected when A=0, B=1 |
| 5 | 1C1 | Data input 1 for section 1; selected when A=1, B=0 |
| 6 | 1C0 | Data input 0 for section 1; selected when A=0, B=0 |
| 7 | 1Y | Output of section 1; reflects selected C-input when 1G is low |
| 8 | GND | Ground reference for all internal logic and output stages |
| 9 | VCC | +5 V supply for CMOS core and output drivers |
| 10 | 2G (Strobe 2) | Active-low enable for second multiplexer section; independent control enables time-multiplexed routing |
| 11 | A (Select A) | LSB of 2-bit binary select code common to both sections; paired with B for full 4:1 decoding |
| 12 | 2C3 | Data input 3 for section 2; identical routing behavior to 1C3 under same A/B conditions |
| 13 | 2C2 | Data input 2 for section 2; mirrors 1C2 functionality in parallel section |
| 14 | 2C1 | Data input 1 for section 2; synchronized selection with section 1 via shared A/B |
| 15 | 2C0 | Data input 0 for section 2; completes dual 4:1 structure with independent strobes |
| 16 | 2Y | Output of section 2; electrically isolated from 1Y, allowing concurrent or staggered data routing |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 4:1 multiplexers | Enables two simultaneous or time-sliced data routing paths using shared select lines and separate enables |
| TTL-compatible input thresholds | Eliminates level-shifting circuitry when interfacing with 74LS, 74F, or microcontroller GPIOs operating at 5 V |
| ±24-mA output drive capability | Directly drives multiple downstream logic inputs or short PCB traces without fanout buffers |
| Balanced propagation delays | Minimizes timing skew between select, data, and strobe paths-critical for glitch-free bus arbitration |
| SCR-latchup-resistant CMOS process | Prevents destructive latchup under transient overvoltage or ESD events in harsh electrical environments |
| MIL-STD-883 certified ESD protection | Ensures reliability during manual handling and board-level integration without special ESD precautions |

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 |
|---|---|---|---|
| SN74ACT153N | Same ACT logic family, identical function and pinout, but in PDIP-16 package (not SOIC); higher θJA (67°C/W vs. 73°C/W) | Preferred for prototyping or through-hole PCBs; lacks surface-mount thermal performance and reflow compatibility | Select SN74ACT153N only when hand-soldering or socket-based validation is required. |
| CD74HC153M | HC-family variant: lower drive (±5.2 mA), slower propagation (17–40 ns), no TTL input compatibility (VIH = 3.15 V min) | Suitable for low-power, low-speed systems where 5-V TTL interfacing is unnecessary and fanout is minimal | Choose CD74HC153M only if power budget is constrained and legacy TTL devices are absent from the system. |
Compared with SN74ACT153N and CD74HC153M, the CD74ACT153M uniquely combines SOIC-16 surface-mount compatibility, full TTL input voltage support, and ±24-mA drive-making it optimal for space-constrained, mixed-logic industrial controllers requiring robust signal routing.

FAQ
What is the maximum operating temperature range for CD74ACT153M?
The CD74ACT153M is rated for operation from –55°C to 125°C, as confirmed in the recommended operating conditions table of the SCHS339 datasheet. This extended range qualifies it for aerospace, military, and harsh-environment industrial applications where standard commercial-grade logic would fail. The SOIC package maintains thermal integrity across this span due to its defined θJA of 73°C/W.
Does CD74ACT153M support 3.3-V logic inputs?
No, CD74ACT153M does not reliably support 3.3-V logic inputs. Its input thresholds are TTL-compatible: VIH(min) = 2.0 V and VIL(max) = 0.8 V at VCC = 4.5–5.5 V. A 3.3-V CMOS high-level signal may fall below the 2.0-V minimum required for guaranteed recognition as a logic high, risking metastability or incorrect selection. Interface with 3.3-V systems requires level translation.
Can CD74ACT153M be used as a 1-of-4 decoder?
Yes, CD74ACT153M can function as a dual 1-of-4 decoder by tying all C inputs of each section to fixed logic levels (e.g., VCC/GND) and using the Y outputs as decoded enables. Its internal binary decoding structure-driven by shared A/B select lines-naturally maps 2-bit codes to four distinct output states per section, provided strobe (G) is held low during decode operation.
What is the output drive strength of CD74ACT153M at 125°C?
At 125°C, CD74ACT153M maintains ±24-mA output drive capability, as specified in the recommended operating conditions table (IOL = 24 mA, IOH = –24 mA) across the full temperature range. This is verified under worst-case conditions and enables driving 15 F-type loads or 50-Ω transmission lines even at maximum junction temperature, ensuring signal integrity in thermally stressed systems.
Is CD74ACT153M pin-compatible with CD74HC153M?
Yes, CD74ACT153M and CD74HC153M share identical SOIC-16 pinouts and functional block diagrams, including matching pin assignments for A, B, G, C0–C3, Y, VCC, and GND. However, they differ electrically: ACT offers TTL-compatible inputs and ±24-mA drive, while HC has CMOS inputs and ±5.2-mA drive. Direct substitution requires verifying voltage thresholds and load requirements.
