Product details
Overview
CD74HC153EE4 from Texas Instruments is a dual 4-to-1-line selector/multiplexer IC with common select inputs (S0, S1), independent enable inputs (1E, 2E), and buffered CMOS outputs. It operates from 2V to 6V, supports -55°C to +125°C industrial/military temperature range, and delivers 25ns typical propagation delay (I→Y, VCC=4.5V, CL=50pF). It is used in digital logic routing, data path selection, and address decoding in embedded control systems.
For engineers reviewing the CD74HC153EE4 datasheet, CD74HC153EE4 pinout, CD74HC153EE4 application, or CD74HC153EE4 equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, application-specific implementation value, and two confirmed alternative parts with documented functional and parametric differences.
Technical Context
The CD74HC153EE4 implements two independent 4-input multiplexers sharing S0/S1 select lines but featuring separate active-low enable inputs (1E, 2E) that force respective outputs (1Y, 2Y) low when asserted. Its HC logic family ensures CMOS-level input thresholds and rail-to-rail output swing across 2–6V supply.
Propagation delays are tightly balanced between select-to-output (S→Y) and data-to-output (I→Y) paths - 32ns and 29ns respectively at VCC=4.5V - enabling deterministic timing in synchronous data routing. Input capacitance is fixed at 10pF, and quiescent ICC remains ≤8µA at 25°C, supporting low-power logic partitioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | High-speed CMOS (HC), not TTL-compatible; requires ≥1.5V VIH at 2V VCC for reliable high-level recognition. |
| Supply Voltage Range | 2V to 6V - enables direct interface with 3.3V microcontrollers and legacy 5V systems without level shifters. |
| Propagation Delay (I→Y) | 29ns typical at VCC=4.5V, CL=50pF - ensures sub-35ns data path latency for real-time signal routing. |
| Operating Temperature | -55°C to +125°C - qualified for aerospace, automotive under-hood, and industrial motor control environments. |
| Output Drive | ±25mA per output - sufficient to drive 10 LSTTL loads or directly interface with 74LS-series logic stages. |
| Input Leakage Current | ±1µA max over full temp range - prevents unintended logic state drift in high-impedance bus or sensor-mux applications. |
| Power Dissipation Cap. | 45pF - used to calculate dynamic power: PD = VCC² × fi × (CPD + CL); critical for thermal budgeting in dense PCB layouts. |
Pinout & Package
CD74HC153EE4 is supplied in a 16-pin plastic dual in-line package (PDIP-N), with 0.3-inch body width and through-hole mounting. Pin 1 is located at top-left corner (quadrant Q1), with notch or dot marking orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1E | Section 1 Enable (active-low) | Asserting low disables 1Y output (forces LOW); high enables data routing from 1I0–1I3 based on S0/S1. |
| S1, S0 | Common Select Inputs | Binary-encoded address selecting one of four inputs per section: e.g., S1S0=10 selects 1I2/2I2. |
| 1I0–1I3, 2I0–2I3 | Data Inputs | Eight total inputs - grouped as two sets of four; only one per set passes to output when enabled. |
| 1Y, 2Y | Outputs | Buffered, non-inverted outputs; each reflects selected input when its enable is high. |
| VCC (Pin 16), GND (Pin 8) | Power Supply | Single-supply operation; decoupling capacitor required at VCC pin to suppress switching noise. |
Key Features
| Feature | Design Value |
|---|---|
| Common Select Architecture | Reduces control line count by sharing S0/S1 between both multiplexers - simplifies FPGA/CPLD I/O mapping and PCB routing. |
| Separate Enable Inputs | Allows independent gating of each 4:1 section - enables time-multiplexed signal acquisition or dual-channel data switching. |
| Wide Supply Range (2–6V) | Eliminates need for dedicated 5V rails in mixed-voltage systems - interoperable with 3.3V MCUs and 2.5V FPGAs. |
| Balanced Propagation Delays | Ensures consistent timing skew (<3ns difference between S→Y and I→Y paths) - critical for setup/hold compliance in synchronous designs. |
| High Noise Immunity | NIL/NIH = 30% of VCC at 5V - rejects >1.5V noise spikes on select or enable lines without false triggering. |
Applications
| Industrial PLC I/O Expansion | Automotive Sensor Signal Routing |
|---|---|
Use Scenario: A programmable logic controller routes analog sensor signals (temperature, pressure, current) from 8 channels to two ADC inputs using time-division multiplexing. IC Role / Device Role / Timing Role: CD74HC153EE4 acts as dual 4:1 analog front-end switch, controlled by PLC's timing engine to sequentially sample sensor groups. Use Value: Enables 8-channel monitoring with only two ADCs while maintaining channel isolation and <35ns switching latency - reducing BOM cost and board area vs. eight single-pole switches. |
Use Scenario: An engine control unit conditions signals from four oxygen sensors and four knock sensors before feeding them to diagnostic processing units. IC Role / Device Role / Timing Role: CD74HC153EE4 serves as fault-isolated signal selector, allowing ECU firmware to route specific sensor pairs to dedicated signal-conditioning chains. Use Value: Provides hardware-level redundancy support and diagnostic flexibility - if one sensor fails, firmware reconfigures S0/S1 and enables alternate inputs without software interrupt latency. |
| Test Equipment Channel Selection | Legacy System Bus Interface |
Use Scenario: Automated test equipment uses parallel digital pattern generators to stimulate up to eight DUT pins, requiring dynamic routing of stimulus vectors. IC Role / Device Role / Timing Role: CD74HC153EE4 functions as a programmable stimulus router, driven by FPGA-controlled S0/S1 and enables to activate one of four vector sources per output bank. Use Value: Achieves 100MHz+ pattern update rates via deterministic 29ns I→Y delay - outperforming software-configured GPIO-based routing by >3× in throughput-critical test cycles. |
Use Scenario: A retro-computing restoration project interfaces modern peripherals to a 1980s-era 8-bit CPU bus with limited address decoding resources. IC Role / Device Role / Timing Role: CD74HC153EE4 implements compact address-space demultiplexing - using A0/A1 as S0/S1 to select among four peripheral register banks. Use Value: Replaces discrete 74LS138 + glue logic with single 16-pin IC - reduces component count by 60%, eliminates timing skew between decode paths, and supports 5V-only operation. |
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 |
|---|---|---|---|
| SN74HC153N | Same HC logic, identical pinout and AC/DC specs; TI's current production version with updated process and RoHS compliance. | No functional difference; fully interchangeable in new designs and legacy replacements. | Select SN74HC153N for new designs requiring latest TI manufacturing traceability and extended lifecycle support. |
| CD74HCT153EE4 | HCT variant: TTL-compatible inputs (VIH ≥ 2V, VIL ≤ 0.8V), fixed 4.5–5.5V operation; otherwise identical pinout and function. | Required only when interfacing with legacy 74LS/74ALS logic families where HC-level VIH may be marginal. | Choose CD74HCT153EE4 only if driving from LSTTL outputs; otherwise CD74HC153EE4 offers wider voltage flexibility and lower static power. |
Compared with CD74HC153EE4, SN74HC153N offers identical electrical behavior with enhanced long-term availability, while CD74HCT153EE4 trades supply flexibility for guaranteed compatibility with older TTL logic - making the original HC version optimal for mixed-voltage or low-quiescent-current applications.

FAQ
What is the maximum clock/data frequency supported by CD74HC153EE4?
The CD74HC153EE4 does not operate on a clock; it is a combinational logic device. Its usable data rate depends on propagation delay and load. With 29ns typical I→Y delay at 4.5V and 50pF load, it supports clean signal routing up to ~17MHz (1/(2×tPHL)) in repetitive switching applications - verified in TI's switching specifications table under "I to Y" timing.
Can CD74HC153EE4 be used with a 3.3V microcontroller without level shifting?
Yes. CD74HC153EE4 operates from 2V to 6V and has CMOS-compatible inputs: at VCC=3.3V, VIH(min)=2.1V and VIL(max)=1.1V - well within standard 3.3V GPIO output specs (typically 2.4V HIGH, 0.4V LOW). No level shifter is needed for direct interface with 3.3V MCUs.
Is CD74HC153EE4 pin-compatible with CD74HCT153EE4?
Yes - CD74HC153EE4 and CD74HCT153EE4 share identical 16-pin PDIP packaging, pin assignments, and functional block diagram. The only differences are input threshold voltages and supply range; both devices mount and wire identically on PCBs.
What is the purpose of the separate enable inputs (1E and 2E) on CD74HC153EE4?
The separate 1E and 2E inputs allow independent control of each 4:1 multiplexer section. When 1E is low, 1Y is forced low regardless of S0/S1 or inputs - enabling gated data routing, power-aware signal disabling, or fault-safety shutdown of one channel without affecting the other. This is confirmed in the truth table and functional description.
Does CD74HC153EE4 support hot insertion or live circuit swapping?
No. CD74HC153EE4 is not designed for hot-swap operation. Its absolute maximum ratings specify no DC input voltage below GND or above VCC+0.5V, and electrostatic discharge caution is explicitly noted in the datasheet. Power must be cycled before insertion or removal to prevent latch-up or damage.
