Texas Instruments CD74HC153E

Overview

CD74HC153E from Texas Instruments is a dual 4-to-1-line selector/multiplexer IC designed for digital signal routing in logic systems. It features common S0/S1 select inputs, independent 1E/2E enable controls, buffered CMOS inputs/outputs, 2V–6V supply operation, and operates across -55°C to +125°C for aerospace and industrial control applications.

For engineers reviewing the CD74HC153E datasheet, CD74HC153E pinout, CD74HC153E application, or CD74HC153E equivalent, this page delivers verified electrical specs, true pin functions, thermal performance data, real-world multiplexing use cases, and validated alternative parts with documented functional and interface differences.

Technical Context

The CD74HC153E implements two independent 4-input multiplexers sharing select lines S0 and S1, with separate active-low enables (1E, 2E) that force outputs LOW when asserted. Each section routes one of four data inputs (I0–I3) to its output (1Y or 2Y) based on binary S1S0 state.

It uses high-speed CMOS (HC) technology with rail-to-rail output swing, balanced tPLH/tPHL propagation delays (e.g., 29 ns typical at VCC = 4.5V, CL = 50 pF), and input leakage ≤±1 µA over full temperature range - enabling reliable operation in noise-prone embedded control and test equipment environments.

Key Specifications

FAQ

What is the maximum operating supply voltage for CD74HC153E?

The absolute maximum DC supply voltage for CD74HC153E is 7 V, but the recommended operational range is 2 V to 6 V. Operation above 6 V risks exceeding safe power dissipation limits and may degrade long-term reliability. All DC and AC specifications - including propagation delay, noise immunity, and output drive - are guaranteed only within the 2–6 V window per the official Texas Instruments datasheet SCHS151C.

Does CD74HC153E support 3.3V logic systems?

Yes, CD74HC153E fully supports 3.3V operation: its 2V–6V supply range includes 3.3V, and input thresholds scale with VCC (VIH ≥ 2.0V, VIL ≤ 0.99V at VCC = 3.3V). Output VOH reaches ≥3.15V and VOL stays ≤0.1V, ensuring clean interfacing with standard 3.3V CMOS and LVTTL receivers without level translation.

How does the enable logic work on CD74HC153E?

CD74HC153E uses active-HIGH enable inputs (1E and 2E): when either enable is HIGH, the corresponding output (1Y or 2Y) is forced LOW regardless of select or data inputs. When both enables are LOW, each section operates normally - routing the selected I0–I3 input to its Y output based on S1/S0. This allows independent section gating in multi-mux architectures.

Can CD74HC153E be used as an 8:1 multiplexer?

Yes, two CD74HC153E devices can be cascaded to implement an 8:1 multiplexer: connect shared S0/S1 lines to the least-significant bits, use the third select bit to control 1E/2E enables, and OR the two outputs (e.g., via diode-resistor network or external gate). The resulting structure maintains deterministic timing and avoids internal latching - confirmed in TI application note SCBA011.

Is CD74HC153E pin-compatible with CD74HCT153E?

Yes, CD74HC153E and CD74HCT153E share identical PDIP-16 pinouts and logic functions, but differ in input compatibility: CD74HC153E accepts CMOS-level inputs (VIH ≥ 70% VCC), while CD74HCT153E accepts TTL-level inputs (VIH ≥ 2.0V, VIL ≤ 0.8V at VCC = 4.5–5.5V). Swapping them requires verifying source driver voltage levels to prevent logic errors.
