Product details
Overview
CD74AC153EE4 from Texas Instruments is a dual 4-line to 1-line data selector/multiplexer in PDIP-16 package, operating from 1.5 V to 5.5 V, delivering ±24 mA output drive, 3.3 ns typical propagation delay at 5 V, and SCR-latchup-resistant CMOS logic for digital signal routing in industrial control systems.
For engineers reviewing the CD74AC153EE4 datasheet, CD74AC153EE4 pinout, CD74AC153EE4 application, or CD74AC153EE4 equivalent, key selection criteria include dual independent strobe control (1G/2G), common select inputs (A/B), balanced tPLH/tPHL timing, ESD immunity (>2 kV), and operation across –55°C to 125°C.
Technical Context
This device implements two independent 4:1 multiplexer sections using AND-OR logic with inverters and drivers for full binary decoding. Each section has dedicated active-low strobe (G) input and shares select lines A and B, enabling synchronized or isolated channel selection.
It uses a radiation-hardened, SCR-latchup-resistant CMOS process with balanced noise immunity (30% of VCC), supports fanout to 15 F-series devices, and meets MIL-STD-883 ESD requirements - making it suitable for high-reliability analog/digital interface and signal routing applications where supply voltage flexibility and robustness are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 5.5 V - enables interoperability with 1.8 V, 3.3 V, and 5 V logic families without level shifters. |
| Propagation Delay (tPLH/tPHL) | 3.3 ns max at VCC = 5 V, CL = 50 pF - supports high-speed digital bus switching up to ~150 MHz effective throughput. |
| Output Drive Current | ±24 mA - drives standard TTL loads and ≥15 F-series gates directly, reducing need for buffer stages. |
| Input Thresholds (VIH/VIL) | VIL = 1.65 V, VIH = 3.85 V at VCC = 5.5 V - ensures noise margin >1.2 V under worst-case conditions. |
| ESD Protection | >2 kV per MIL-STD-883 Method 3015 - provides robust handling in manual assembly and field-replaceable modules. |
| Operating Temperature | –55°C to +125°C - qualified for extended industrial, aerospace, and defense environments without derating. |
| Power Dissipation Capacitance | 93 pF - enables accurate dynamic power estimation (P = C × V² × f) for thermal design at 10–100 MHz clock rates. |
Pinout & Package
Packaged in 16-pin Plastic Dual Inline Package (PDIP), with 0.3-inch body width, through-hole mounting, and RoHS-compliant lead finish (NIPDAU).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1G, 2G | Active-low strobe enable | Independent gating of each 4:1 section; low enables output Y, high forces Y = high-impedance. |
| A, B | Common binary select inputs | Shared by both sections to determine which of four data inputs (C0–C3) routes to output Y. |
| 1C0–1C3, 2C0–2C3 | Data inputs | Two independent sets of four digital inputs; selected via A/B and enabled by corresponding G. |
| 1Y, 2Y | Outputs | Active-high, non-inverted multiplexed outputs; each reflects selected Cx input when its G is low. |
| VCC, GND | Power rails | Single-supply operation; decoupling capacitor required at VCC pin for stable high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 4:1 multiplexing | Enables two parallel signal routing paths on one IC - reduces board space vs. discrete solutions and simplifies PCB layout. |
| Balanced propagation delays | tPLH ≈ tPHL across all input-to-output paths - minimizes skew in time-critical address/data selection and avoids setup/hold violations. |
| Wide supply range (1.5 V–5.5 V) | Eliminates need for separate voltage translators when interfacing mixed-voltage subsystems (e.g., 1.8 V FPGA to 5 V DAC). |
| ±24 mA output drive | Directly drives multiple downstream logic inputs or small-signal analog switches without external buffers. |
| MIL-STD-883 ESD rating | Supports ruggedized test fixtures and field-deployable equipment where electrostatic discharge events are frequent. |
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 |
|---|---|---|---|
| SN74AC153N | Same AC logic family, identical pinout, but rated only for –40°C to +85°C industrial range. | Limited to commercial/industrial environments; lacks extended temperature qualification. | Select when operating ambient stays within 85°C and cost sensitivity outweighs military-grade reliability. |
| CD74HC153E | HC-family variant: higher VCC min (2 V), slower max speed (28 ns at 5 V), lower drive (±4 mA). | Suitable for low-power, low-frequency designs where propagation delay and drive strength are less critical. | Choose for battery-powered or thermally constrained systems where 28 ns latency and 4 mA drive are acceptable. |
Compared with SN74AC153N and CD74HC153E, CD74AC153EE4 uniquely combines extended temperature range (–55°C to +125°C), ±24 mA drive, and 3.3 ns propagation - making it the only option qualified for high-reliability, high-speed, wide-voltage industrial and defense applications without performance trade-offs.

FAQ
What is the maximum operating frequency supported by CD74AC153EE4?
The CD74AC153EE4 does not specify a maximum clock frequency in its datasheet because it is a combinational logic device without an internal clock. Its usable switching rate depends on propagation delay and system-level timing margins. At VCC = 5 V and CL = 50 pF, tPLH/tPHL is 3.3 ns (max), supporting reliable operation up to approximately 150 MHz in well-designed PCB layouts with controlled impedance and proper decoupling. The CD74AC153EE4 must be used with clean, monotonic input edges meeting specified ∆t/∆v limits (20 ns/V at 5 V) to avoid metastability or false switching.
Does CD74AC153EE4 support 1.8 V logic levels?
Yes, CD74AC153EE4 supports 1.8 V logic levels as part of its 1.5 V to 5.5 V supply range. When operated at VCC = 1.8 V, its input thresholds scale accordingly (VIH ≈ 1.26 V, VIL ≈ 0.54 V), providing adequate noise margin for 1.8 V systems. Output VOH/VOL remain rail-to-rail, ensuring compatibility with downstream 1.8 V CMOS inputs. However, propagation delay increases to ~250 ns at 1.5 V, so timing-critical paths should verify setup/hold margins using the 1.5 V switching characteristics table. The CD74AC153EE4 maintains full functionality across this entire voltage range without configuration changes.
How are the strobe inputs (1G and 2G) used in CD74AC153EE4?
The strobe inputs 1G and 2G on CD74AC153EE4 are active-low enables for each of the two independent 4:1 multiplexer sections. When 1G is low, the first section routes the selected C0–C3 input (determined by A/B) to 1Y; when 1G is high, 1Y is forced high-impedance. Similarly, 2G controls the second section's output 2Y. This allows time-multiplexed or conditional routing - for example, using one section for primary data and the other for backup or diagnostic signals. Both sections share A and B select lines, enabling synchronized channel selection. The CD74AC153EE4 datasheet confirms this behavior in the function table and logic diagram, with no internal coupling between strobes.
Is CD74AC153EE4 pin-compatible with CD74HC153E?
No, CD74AC153EE4 is not pin-compatible with CD74HC153E. While both are dual 4:1 multiplexers in 16-pin PDIP packages and share identical pin numbering (per TI package drawings N for CD74AC153EE4 and N for CD74HC153E), they differ electrically and thermally: CD74AC153EE4 is rated for –55°C to +125°C and delivers ±24 mA drive, whereas CD74HC153E is rated only for –40°C to +85°C and provides ±4 mA. Substituting one for the other requires validation of timing, drive capability, and temperature compliance. The CD74AC153EE4 cannot be treated as a drop-in replacement without reviewing system-level electrical and thermal margins.
What packaging and compliance information applies to CD74AC153EE4?
CD74AC153EE4 is supplied in a 16-pin Plastic Dual Inline Package (PDIP) with body width 0.3 inch, RoHS-compliant green finish (no Sb/Br), and NIPDAU lead termination. It is rated for moisture sensitivity level (MSL) "N/A for Pkg Type" per JEDEC J-STD-020, meaning it is not moisture-sensitive and requires no bake-out prior to soldering. The device carries TI's standard 10-year product longevity commitment for industrial applications and conforms to MIL-STD-883 ESD requirements (>2 kV). Traceability is maintained via top-side marking "CD74AC153E", and the CD74AC153EE4 is manufactured under TI's certified quality management system compliant with ISO 9001 and IATF 16949.
