Product details
Overview
CD74HC153EG4 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 (CL = 50pF, VCC = 4.5V) in high-noise-immunity logic. It is used in digital data routing, address decoding, and bus selection circuits where dual independent multiplexing is required.
For engineers reviewing the CD74HC153EG4 datasheet, CD74HC153EG4 pinout, CD74HC153EG4 application, or CD74HC153EG4 equivalent, this page provides verified functional identity, validated 16-pin PDIP package mapping, confirmed dual-mux architecture with shared select lines, real-world timing specs under load, and two technically documented alternative parts for design flexibility.
Technical Context
The CD74HC153EG4 implements two independent 4-input multiplexers sharing S0 and S1 select lines but featuring separate enable (1E, 2E) and output (1Y, 2Y) terminals. Each section selects one of four data inputs (I0–I3) based on binary S1S0 state, with active-low enable asserting low-impedance output only when enabled.
It uses standard HC-series CMOS technology: rail-to-rail input thresholds (VIH = 1.5V min at VCC = 2V; VIL = 0.5V max), 10 LSTTL fanout capability, and balanced tPLH/tPHL propagation delays. Input leakage remains ≤±1 µA across full temperature range, and quiescent ICC is ≤160 µA at VCC = 6V and TA = -55°C to +125°C.
Key Specifications

Pinout & Package
CD74HC153EG4 is supplied in a 16-lead plastic dual in-line package (PDIP), with 0.3-inch body width and through-hole mounting. Pin 1 is located at the top-left corner (notch-side left), and pin numbering proceeds counter-clockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1E | Section 1 Enable (active-low) | Drives 1Y low when HIGH; disables 1Y (high-impedance) when LOW |
| S1 | Common Select Input MSB | Jointly controls both mux sections; defines I3/I2/I1/I0 selection with S0 |
| 1I3–1I0 | Section 1 Data Inputs | Four independent digital inputs routed to 1Y based on S1S0 state |
| GND | Ground Reference | Pins 8 (GND) and 16 (VCC) define power rails; decoupling capacitor required at VCC–GND |
| 1Y | Section 1 Output | Active-low enabled, buffered CMOS output with rail-to-rail swing |
| VCC | Positive Supply | Accepts 2V–6V; must be stable within ±5% for guaranteed timing and noise immunity |
| S0 | Common Select Input LSB | Paired with S1 to generate 2-bit select code (00–11) for input selection |
| 2I3–2I0 | Section 2 Data Inputs | Second independent set of four inputs, sharing S1/S0 but isolated from Section 1 |
| 2Y | Section 2 Output | Independent buffered output, identical timing and drive strength as 1Y |
| 2E | Section 2 Enable (active-low) | Independent control of Section 2 output; no interaction with Section 1 logic |
Key Features

Applications
| Industrial PLC I/O Expansion | Aerospace Avionics Signal Routing |
|---|---|
|
Use Scenario: Multiplexing analog sensor readings (temperature, pressure, voltage) from multiple channels into a single ADC input via digital control. IC Role / Device Role / Timing Role: Dual 4-to-1 selector routes up to eight discrete analog front-end signals using shared S0/S1 and independent enables for channel arbitration. Use Value: Reduces component count versus two discrete 4:1 muxes while maintaining independent enable control per sensor group-enabling staggered sampling without cross-talk. |
Use Scenario: Selecting between redundant flight control data buses (Bus A/B/C/D) for real-time validation and failover decision logic. IC Role / Device Role / Timing Role: Acts as a deterministic, low-latency signal switch in safety-critical path; S0/S1 driven by fault-monitoring FSM, 1E/2E synchronized to health status flags. Use Value: Guaranteed 48 ns max propagation delay ensures sub-100 ns bus switching - critical for meeting DO-254 timing budgets in Level A avionics hardware. |
| Test Equipment Digital Pattern Selection | Legacy System Bus Interface Adapter |
|
Use Scenario: Generating programmable stimulus patterns for IC functional testing by selecting among preloaded 4-bit test vectors stored in parallel latches. IC Role / Device Role / Timing Role: Dual mux provides two simultaneous 4-bit word selections (e.g., address + data), synchronized to test clock edge. Use Value: Buffered outputs drive heavy capacitive loads (≥50 pF) on test fixture wiring without skew or rise-time degradation-ensuring setup/hold compliance at 20 MHz pattern rates. |
Use Scenario: Adapting 8-bit microcontroller address/data bus to legacy peripheral chips requiring 4-bit nibble-wide access (e.g., older display drivers or EEPROMs). IC Role / Device Role / Timing Role: Routes upper/lower nibbles independently using 1Y/2Y outputs, with S0/S1 tied to A0/A1 and enables controlled by chip-select decode logic. Use Value: HC logic family's 2V–6V supply range allows direct interface to both 3.3V MCUs and 5V peripherals-eliminating level-shifter components. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4-to-1 multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC153N | Same pinout, identical AC/DC specs, TI second-source part with identical -55°C to +125°C rating | No functional difference; fully interchangeable in all designs using CD74HC153EG4 | Select SN74HC153N when sourcing from distributors with broader stock of TI's commercial-grade HC portfolio |
| MC74HC153ANG | Onsemi variant; identical logic function, same 16-pin PDIP package, but specified only to -40°C to +85°C | Not suitable for extended-temperature applications; requires thermal validation if used outside commercial temp range | Choose MC74HC153ANG only for cost-sensitive commercial equipment where full military-grade temp range is unnecessary |
Compared with CD74HC153EG4, SN74HC153N offers identical performance and qualification, while MC74HC153ANG trades extended temperature support for lower unit cost-making the former ideal for drop-in replacement and the latter appropriate only for ambient-stable environments.

FAQ
What is the logic family and supply voltage range of CD74HC153EG4?
The CD74HC153EG4 is a high-speed CMOS (HC) logic device rated for 2V to 6V operation. It is not TTL-compatible-its input thresholds scale with VCC (e.g., VIH ≥ 1.5V at VCC = 2V). This enables flexible integration into mixed-voltage systems while maintaining noise immunity of ≥30% of VCC at 5V. The CD74HC153EG4 does not support 4.5V–5.5V-only HCT operation.
Does CD74HC153EG4 support independent selection for each multiplexer section?
No-CD74HC153EG4 features common select inputs S0 and S1 shared between both 4-to-1 sections. Independent data routing is achieved solely via separate enable inputs (1E and 2E), which gate the respective outputs (1Y and 2Y). To select different inputs for each section, external logic must dynamically reconfigure S0/S1 before enabling each section sequentially.
What is the maximum propagation delay for CD74HC153EG4 under worst-case conditions?
The CD74HC153EG4 has a maximum propagation delay of 240 ns for S→Y paths at VCC = 2V and TA = -55°C to +125°C (CL = 50pF). At nominal 4.5V operation and 25°C, typical delay is 32 ns with a max of 48 ns. These values are measured from select/input transition to valid output transition at 50% VCC, per Figure 1 in the official datasheet.
Can CD74HC153EG4 drive standard TTL loads directly?
Yes-the CD74HC153EG4 is specified for 10 LSTTL loads per output. Its VOH ≥ 4.4V and VOL ≤ 0.1V at VCC = 4.5V meet TTL input requirements (VIH ≥ 2.0V, VIL ≤ 0.8V). However, it lacks HCT-level input compatibility: its VIH threshold is VCC-dependent, so direct connection to legacy TTL outputs may require verification of voltage margins at the specific VCC used.
Is CD74HC153EG4 RoHS compliant and what is its packaging format?
Yes, CD74HC153EG4 is RoHS compliant (lead-free NiPdAu finish) and supplied in a 16-lead plastic dual in-line package (PDIP) with 0.3-inch width, tube packaging (25 units per tube), and JEDEC-standard pinout. The "G4" suffix denotes green (halogen-free) RoHS-compliant packaging per TI's specification, distinct from older leaded variants.
