Product details
Overview
CD74HCT153EE4 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 CMOS/TTL-compatible logic interfaces. It operates from 4.5 V to 5.5 V, delivers propagation delays as low as 24 ns (I to Y, CL = 50 pF, 25°C), supports -55°C to +125°C industrial/military temperature range, and drives up to 10 LSTTL loads. It is used in digital signal routing, address decoding, and data path selection in embedded control systems.
For engineers reviewing the CD74HCT153EE4 datasheet, CD74HCT153EE4 pinout, CD74HCT153EE4 application, or CD74HCT153EE4 equivalent, key selection criteria include its HCT-level input compatibility (VIH ≥ 2 V, VIL ≤ 0.8 V), dual-section independent enable control, guaranteed operation across extended temperature, and PDIP-16 package suitability for prototyping and high-reliability board-level integration.
Technical Context
The CD74HCT153EE4 implements two independent 4-input multiplexers sharing S0/S1 select lines but featuring separate 1E/2E enables-enabling selective activation of each section without affecting the other. Its HCT logic family ensures direct interface with legacy LSTTL outputs while maintaining CMOS power efficiency.
Each multiplexer output (1Y, 2Y) is actively driven LOW when its corresponding enable is HIGH; otherwise, the output is disabled (high-impedance state is not supported-outputs go LOW when enabled, and remain LOW when disabled per truth table). Propagation delay is specified separately for S→Y, I→Y, and E→Y paths, with worst-case tPHL/tPLH ≤ 51 ns over full temperature range at VCC = 4.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | HCT - TTL-compatible inputs, CMOS power efficiency, 4.5–5.5 V supply |
| Function | Dual 4-to-1 selector/multiplexer with common S0/S1, independent 1E/2E enables |
| Propagation Delay (I→Y) | 24 ns max (25°C, CL = 50 pF, VCC = 4.5 V) - determines maximum data rate in routing paths |
| Input Voltage Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - ensures reliable interfacing with 5 V LSTTL outputs |
| Operating Temperature | -55°C to +125°C - qualified for military, aerospace, and harsh-environment industrial use |
| Output Drive | 10 LSTTL loads - sufficient fanout for driving multiple downstream logic inputs without buffering |

Pinout & Package
CD74HCT153EE4 is supplied in a 16-pin plastic dual in-line package (PDIP-N), with 0.3-inch body width and through-hole mounting. Pin 8 is GND, pin 16 is VCC, and pin numbering follows standard DIP orientation (pin 1 in top-left corner, counterclockwise).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1E | Section 1 Enable Input | Active-HIGH enable: when HIGH, 1Y reflects selected 1I0–1I3; when LOW, 1Y forced LOW |
| S1, S0 | Common Select Inputs | Binary address selecting one of four data inputs per section (00→1I0, 01→1I1, etc.) |
| 1I0–1I3 | Section 1 Data Inputs | Four independent digital inputs routed to 1Y based on S1/S0 state when 1E = HIGH |
| 1Y | Section 1 Output | Active-LOW output: driven LOW when 1E = HIGH and selected input is LOW; driven LOW when 1E = LOW regardless of inputs |
| GND (Pin 8) | Ground Reference | Power return path for all internal logic and output stages |
| VCC (Pin 16) | Positive Supply | 4.5–5.5 V DC supply for CMOS core and output buffers |
| 2I0–2I3 | Section 2 Data Inputs | Second independent set of four inputs, sharing S1/S0 but controlled by 2E |
| 2Y | Section 2 Output | Identical behavior to 1Y, controlled by 2E instead of 1E |
| 2E | Section 2 Enable Input | Independent active-HIGH enable for second multiplexer section |
Key Features
| Feature | Design Value |
|---|---|
| Common select architecture | Reduces PCB routing complexity by sharing S0/S1 between both 4:1 sections |
| Independent section enables | Enables time-multiplexed or conditional routing - e.g., one section active during read, other during write |
| LSTTL input compatibility | Eliminates level-shifting requirements when interfacing with legacy 5 V TTL microcontrollers or FPGAs |
| Extended temperature operation | Supports deployment in under-hood automotive ECUs, downhole instrumentation, and defense avionics |
| Low quiescent current | 160 µA max over full temperature range minimizes standby power in battery-backed systems |

FAQ
What is the supply voltage range for CD74HCT153EE4?
The CD74HCT153EE4 operates strictly within 4.5 V to 5.5 V. Operation outside this range violates absolute maximum ratings and may cause permanent damage or unpredictable logic behavior. The device is not rated for 3.3 V or 2.5 V operation - use HC-series variants (e.g., CD74HC153) for lower-voltage systems.
Does CD74HCT153EE4 support high-impedance (tri-state) outputs?
No, CD74HCT153EE4 does not provide tri-state outputs. When an enable input (1E or 2E) is LOW, the corresponding output (1Y or 2Y) is forced LOW - not high-impedance. This differs from some multiplexers with active-Low enables and true three-state outputs. System design must accommodate this active-LOW disable behavior.
Can CD74HCT153EE4 be used with 3.3 V logic inputs?
No - CD74HCT153EE4 requires VIH ≥ 2.0 V and VIL ≤ 0.8 V, but its input thresholds are optimized for 5 V LSTTL compatibility. A 3.3 V logic HIGH may fall below the guaranteed VIH minimum under voltage or temperature variation, risking misreads. Use a level translator or select a 3.3 V–compatible multiplexer such as SN74LVC153A.
What is the maximum clock/data rate supported by CD74HCT153EE4?
CD74HCT153EE4 does not operate on a clock; it is combinatorial. Its maximum usable data rate depends on propagation delay and system setup/hold timing. With tPLH/tPHL ≤ 51 ns (worst-case over temperature), it supports reliable signal routing up to approximately 10 MHz in synchronous systems where input stability is maintained for >50 ns before and after select transitions.
Is CD74HCT153EE4 RoHS compliant?
Yes, CD74HCT153EE4 is RoHS compliant, as confirmed in TI's Packaging Information Addendum: "Yes" under RoHS column, with lead finish NIPDAU (nickel/palladium/gold) and exemption status aligned with EU Directive 2011/65/EU. Full compliance documentation is available via TI's Quality & Environmental page.
