Product details
Overview
CD74ACT153E from Texas Instruments is a dual 4-line-to-1-line data selector/multiplexer in PDIP-16 package, featuring TTL-voltage-compatible inputs, ±24-mA output drive, balanced propagation delays (4.5–22 ns), and SCR-latchup-resistant CMOS process. It operates across –55°C to 125°C and is used in digital logic routing, address/data path selection, and bus multiplexing in industrial control systems.
For engineers reviewing the CD74ACT153E datasheet, CD74ACT153E pinout, CD74ACT153E application, or CD74ACT153E equivalent, key selection criteria include dual independent strobe control (1G/2G), common select lines (A/B), guaranteed 5-V operation with 4.5–5.5 V supply range, and MIL-STD-883-compliant ESD protection exceeding 2 kV.
Technical Context
The CD74ACT153E integrates two independent 4:1 multiplexer sections sharing select inputs A and B, each with dedicated active-low strobe (1G, 2G) enabling asynchronous section enable/disable. Its logic diagram confirms full binary decoding via inverters and AND-OR gates - no external decoding logic required.
It uses ACT-series advanced CMOS technology delivering bipolar-equivalent speed (e.g., tPLH/tPHL ≤ 22 ns at –55°C to 125°C) with significantly lower ICC (≤ 160 µA typical quiescent current) than legacy F/AS/S families. Input transition rate tolerance is specified at 10 ns/V, supporting clean switching in noisy environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures compatibility with standard 5-V TTL and CMOS systems without level-shifting. |
| Output Drive | ±24 mA - supports fanout to 15 F-series devices or direct driving of 50-Ω transmission lines. |
| Propagation Delay | 4.5 ns (min) to 22 ns (max) - enables reliable timing in high-speed digital control and data routing up to ~20 MHz. |
| Input Compatibility | TTL-voltage levels (VIH = 2 V, VIL = 0.8 V) - allows seamless interfacing with legacy 74LS/TTL logic without pull-ups or buffers. |
| ESD Protection | >2 kV per MIL-STD-883 Method 3015 - provides robust handling margin during board assembly and field operation. |
| Operating Temperature | –55°C to +125°C - qualified for extended-range industrial, aerospace, and automotive under-hood applications. |
| Power Dissipation Cap. | 93 pF Cpd - enables accurate dynamic power estimation in clocked systems using P = Cpd × V² × f. |
Pinout & Package
CD74ACT153E is housed in a 16-pin plastic dual in-line package (PDIP-N), with 0.3-inch body width, 0.1-inch lead pitch, and through-hole mounting. Pin 1 is marked by a notch or dot at the top-left corner (top view).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1G | Section 1 Strobe (active low) | Enables/disables first 4:1 mux independently; high = output Y1 forced low regardless of selects. |
| B | Common Select Bit (MSB) | Shared between both sections; determines upper bit of 2-bit binary address (BA = 00–11). |
| 1C3–1C0 | Section 1 Data Inputs | Four parallel data inputs for first multiplexer; selected by A/B and enabled by 1G. |
| 1Y | Section 1 Output | Active-high, non-inverted output of first 4:1 mux; driven only when 1G = low. |
| GND | Ground Reference | Primary return path for all logic and output currents; must be low-impedance for noise immunity. |
| VCC | Positive Supply | 5-V nominal supply; decoupling capacitor (0.1 µF) required within 1 cm of this pin. |
| 2G | Section 2 Strobe (active low) | Independent enable for second 4:1 mux; allows time-multiplexed or conditional routing. |
| A | Common Select Bit (LSB) | Shared LSB with B; together they decode four input channels per section. |
| 2C3–2C0 | Section 2 Data Inputs | Second set of four inputs; identical function to 1C3–1C0 but electrically isolated. |
| 2Y | Section 2 Output | Independent output for second section; supports dual-path signal routing without contention. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent strobes (1G/2G) | Enables time-sliced or conditional data routing - e.g., alternating between sensor banks without external gating logic. |
| TTL-compatible inputs | Eliminates need for level translators when interfacing with 74LS, 74F, or microcontroller GPIOs operating at 5 V. |
| SCR-latchup-resistant process | Prevents destructive latch-up under transient overvoltage or hot-insertion conditions in industrial backplanes. |
| Balanced tPLH/tPHL | Minimizes duty-cycle distortion in clock/data recovery paths - critical for synchronous bus arbitration. |
| –55°C to +125°C operation | Validated performance across full military temperature range without derating, suitable for engine control units. |
Applications

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 pinout, identical AC/DC specs, but manufactured by TI under commercial-grade (–40°C to +85°C) qualification. | Limited to commercial temperature range; not rated for extended industrial or military use. | Select SN74ACT153N only for cost-sensitive consumer or lab-grade equipment where ambient stays below 85°C. |
| CD74HC153E | Same pinout and function, but HC-series: lower drive (±4 mA), slower max speed (tPD ≈ 29 ns), wider VCC range (2–6 V). | Lower power consumption at low frequencies; unsuitable for driving transmission lines or F-family loads. | Choose CD74HC153E for battery-powered or mixed-voltage systems needing 3.3/5-V flexibility, not high-speed or high-drive needs. |
Compared with SN74ACT153N and CD74HC153E, the CD74ACT153E uniquely combines military-grade temperature range, ±24-mA drive, and sub-22 ns propagation - making it the only option for ruggedized 5-V systems requiring both speed and reliability.

FAQ
What is the maximum operating frequency supported by the CD74ACT153E?
The CD74ACT153E does not specify a maximum clock frequency directly, but its worst-case propagation delay is 22 ns (–55°C to 125°C). Assuming setup/hold times are met, this supports reliable operation up to approximately 20 MHz in synchronous routing applications. For precise timing analysis, designers must verify tPLH/tPHL, tSU, and tH relative to their system clock edge using the values in the switching characteristics table of the CD74ACT153E datasheet.
Can the CD74ACT153E operate at 3.3 V?
No, the CD74ACT153E is not characterized or guaranteed for operation at 3.3 V. Its recommended operating voltage is strictly 4.5 V to 5.5 V, and its TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max) assume a 5-V supply. Using 3.3 V risks unreliable logic recognition, increased propagation delay, and potential failure to meet output drive specifications. For 3.3-V systems, consider the CD74HC153E instead.
Is the CD74ACT153E pin-compatible with the CD74HC153E?
Yes, the CD74ACT153E and CD74HC153E share identical PDIP-16 pinouts and functional block diagrams, including pin assignments for 1G, A, B, 1C0–1C3, 1Y, GND, VCC, 2G, 2C0–2C3, and 2Y. However, they differ electrically: CD74ACT153E requires 4.5–5.5 V and delivers ±24 mA, while CD74HC153E operates from 2–6 V and drives only ±4 mA. Swapping them requires verifying supply voltage and load compatibility.
Does the CD74ACT153E require pull-up or pull-down resistors on unused inputs?
Yes - per TI's application report SCBA004, all unused inputs of the CD74ACT153E must be tied to either VCC or GND to prevent floating nodes, which can cause excessive ICC, oscillation, or premature device failure. Leaving inputs unconnected violates the recommended operating conditions and may result in unpredictable behavior, especially at temperature extremes or under EMI stress.
What is the thermal resistance (θJA) of the CD74ACT153E package?
The CD74ACT153E in its PDIP-E package has a junction-to-ambient thermal resistance (θJA) of 67°C/W, as specified in the absolute maximum ratings table. This value assumes standard JEDEC test board conditions (single-layer copper, 1 in² pad). Actual board-level θJA will vary depending on PCB layout, copper area, airflow, and nearby heat sources - designers should perform thermal analysis using this baseline and derate accordingly for continuous operation near maximum ICC.
