Product details
Overview
CD74ACT153EG4 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 CD74ACT153EG4 datasheet, CD74ACT153EG4 pinout, CD74ACT153EG4 application, or CD74ACT153EG4 equivalent, key selection considerations include its dual-section independent strobe (G) control, common select inputs (A/B), 5-V supply compatibility, and 2-kV ESD protection per MIL-STD-883.
Technical Context
This device integrates two independent 4:1 multiplexer sections sharing select lines A and B, each with dedicated active-low strobe (1G, 2G) enabling asynchronous gating. Each section routes one of four data inputs (C0–C3) to its output (1Y or 2Y) based on binary select state.
It uses ACT-series advanced CMOS technology delivering bipolar-speed performance (tPLH/tPHL down to 4.5 ns) with CMOS power efficiency (ICC ≤ 160 µA at 125°C). Input thresholds meet TTL voltage levels (VIH = 2 V, VIL = 0.8 V), ensuring direct interfacing with legacy 74LS/74F logic without level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures stable operation with standard 5-V logic rails and tolerance for supply ripple. |
| Propagation Delay | 4.5 ns (min) to 22 ns (max) - Enables reliable timing in high-speed digital systems up to ~45 MHz clock-equivalent throughput. |
| Output Drive | ±24 mA - Supports fanout to 15 F-series devices or direct driving of 50-Ω transmission lines at 85°C. |
| Input Compatibility | TTL-voltage-level - Accepts 0.8 V / 2.0 V thresholds, eliminating need for external level translators when interfacing with 74LS/74F families. |
| ESD Protection | ≥2 kV per MIL-STD-883 Method 3015 - Provides robust handling margin during board assembly and field service in industrial environments. |
| Operating Temperature | –55°C to +125°C - Qualified for extended-range applications including aerospace, defense, and under-hood automotive electronics. |
| Quiescent Current | 8 µA typical at 25°C - Minimizes standby power in battery-backed or low-power monitoring subsystems. |
Pinout & Package
CD74ACT153EG4 is housed in a 16-pin plastic dual in-line package (PDIP-N), with 0.3-inch body width and through-hole mounting. Pin 1 is identified by a notch or dot; leads are tin-lead (NIPDAU) finish, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1G | Section 1 strobe input | Active-low enable controlling data routing for first 4:1 section; high-Z output when asserted high. |
| B | Common select bit (MSB) | Shared binary select line determining C0–C3 routing for both sections; must be stable during switching. |
| 1C3 | Section 1 data input 3 | Highest-order data input for first multiplexer; routed to 1Y when A=1, B=1. |
| 1C2 | Section 1 data input 2 | Second-highest data input for first section; selected when A=0, B=1. |
| 1C1 | Section 1 data input 1 | Second-lowest data input for first section; selected when A=1, B=0. |
| 1C0 | Section 1 data input 0 | Lowest-order data input for first section; selected when A=0, B=0. |
| 1Y | Section 1 output | Inverting output of first 4:1 section; reflects selected Cn with polarity inversion per logic diagram. |
| GND | Ground reference | Primary return path for all internal logic and I/O; requires low-impedance connection to minimize noise coupling. |
| VCC | Positive supply | 5-V power rail; decoupling capacitor (0.1 µF ceramic) required within 1 cm of pin for stable high-speed operation. |
| 2G | Section 2 strobe input | Independent active-low enable for second 4:1 section; allows time-multiplexed or parallel channel control. |
| A | Common select bit (LSB) | Shared binary select line (with B); LSB determines C0/C1 vs C2/C3 group selection for both sections. |
| 2C3 | Section 2 data input 3 | Highest-order data input for second multiplexer; functionally identical to 1C3 but isolated signal path. |
| 2C2 | Section 2 data input 2 | Second-highest data input for second section; enables independent data routing concurrent with Section 1. |
| 2C1 | Section 2 data input 1 | Second-lowest data input for second section; supports dual-channel signal selection without interdependence. |
| 2C0 | Section 2 data input 0 | Lowest-order data input for second section; completes full 8-input, 2-output multiplexing capability. |
| 2Y | Section 2 output | Inverting output of second 4:1 section; electrically isolated from 1Y, allowing independent load driving. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 4:1 sections | Enables simultaneous routing of two separate 4-input data streams using shared select lines-reducing PCB routing complexity versus discrete solutions. |
| TTL-compatible inputs | Eliminates level-shifter ICs when interfacing with legacy 74LS/74F families, lowering BOM count and layout area in mixed-logic designs. |
| ±24-mA output drive | Directly drives 50-Ω transmission lines or multiple F-series loads without buffer amplifiers-critical for backplane and bus arbitration circuits. |
| SCR-latchup-resistant process | Prevents destructive latch-up under transient overvoltage or ESD events, enhancing reliability in noisy industrial power environments. |
| Balanced tPLH/tPHL | Minimizes duty-cycle distortion in clock/data recovery paths where symmetric rise/fall timing is essential for setup/hold compliance. |
Applications
| Industrial PLC I/O Multiplexing | Legacy System Bus Arbitration |

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-family specs, identical pinout and timing, but TI's commercial-grade variant rated for –40°C to +85°C only. | Limited to non-military/industrial ambient environments; unsuitable for extended temperature deployments. | Select SN74ACT153N only if operating temperature stays within commercial range and cost sensitivity outweighs extended qualification needs. |
| CD74HC153E | High-speed CMOS version: lower drive (±7.8 mA), slower max speed (29 ns), no TTL input compatibility, but lower ICC (4 µA). | Requires level translation for 74LS interfaces; insufficient for driving 50-Ω lines or F-family loads. | Choose CD74HC153E only for ultra-low-power, low-noise, room-temperature applications where drive strength and interface compatibility are secondary. |
Compared with SN74ACT153N, CD74ACT153EG4 adds military-grade temperature range and enhanced ESD robustness; versus CD74HC153E, it delivers 3× higher output current and native TTL interoperability-making it the sole choice for ruggedized, mixed-logic, high-drive multiplexing.

FAQ
What is the maximum operating temperature range for CD74ACT153EG4?
The CD74ACT153EG4 is specified for continuous operation from –55°C to +125°C, meeting extended temperature requirements for aerospace, defense, and under-hood automotive applications. This rating is validated per MIL-PRF-38535 for qualified versions and confirmed in the SCHS339 datasheet absolute maximum and recommended operating conditions tables.
Does CD74ACT153EG4 support direct interface with 74LS-series logic?
Yes, CD74ACT153EG4 features TTL-voltage-compatible inputs (VIH = 2.0 V min, VIL = 0.8 V max), enabling direct connection to 74LS outputs without level-shifting circuitry. Its input thresholds match LS-family specifications, and its 24-mA drive ensures reliable fanout to LS inputs.
Is CD74ACT153EG4 pin-compatible with CD74HC153E?
No, CD74ACT153EG4 and CD74HC153E share identical pinout and package (PDIP-16), but differ in electrical behavior: CD74ACT153EG4 has TTL-compatible inputs and ±24-mA drive, whereas CD74HC153E uses CMOS thresholds and ±7.8-mA drive. Interchange requires validation of signal levels and load requirements.
What is the purpose of the separate G (strobe) inputs on CD74ACT153EG4?
The independent 1G and 2G inputs on CD74ACT153EG4 provide asynchronous enable/disable control for each 4:1 section. When high, the corresponding output (1Y or 2Y) enters high-impedance state-allowing time-multiplexed use of shared downstream resources like ADC inputs or bus lines without contention.
How does the SCR-latchup-resistant design benefit CD74ACT153EG4 in industrial applications?
The SCR-latchup-resistant CMOS process in CD74ACT153EG4 prevents destructive parasitic thyristor conduction during voltage transients, ESD events, or ground bounce-common in motor-driven industrial environments. This eliminates risk of permanent failure without external protection circuitry, improving system MTBF.
