Texas Instruments CD74HC153M

Overview

CD74HC153M from Texas Instruments is a dual 4-to-1-line selector/multiplexer IC designed for digital signal routing in logic systems. It features two independent 4-input multiplexers sharing common select lines (S0, S1), separate enable inputs (1E, 2E), and operates across 2V–6V supply with -55°C to +125°C temperature range. Its SOIC-16 package supports high-density PCB layouts in industrial control and test equipment.

For engineers reviewing the CD74HC153M datasheet, CD74HC153M pinout, CD74HC153M application, or CD74HC153M equivalent, key selection criteria include its dual-mux architecture, HC-series CMOS compatibility, guaranteed propagation delay (≤48 ns at 4.5V), wide temperature operation, and SOIC-16 footprint suitability for space-constrained embedded designs.

Technical Context

The CD74HC153M implements two independent 4:1 data selectors using standard CMOS logic, where each section routes one of four inputs (1I0–1I3 or 2I0–2I3) to its output (1Y or 2Y) based on binary-encoded S0/S1 states. Enable inputs (1E, 2E) independently disable outputs to LOW when HIGH.

Its HC-family characteristics include rail-to-rail input thresholds (VIH = 1.5V min at 2V VCC; VIL = 0.5V max), low quiescent current (ICC ≤ 160 µA over full temp range), and balanced tPLH/tPHL propagation delays - critical for synchronous logic interfacing and address/data bus selection.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating supply voltage for CD74HC153M?

The CD74HC153M supports a maximum DC supply voltage of 7V, though its recommended operating range is 2V to 6V. Absolute maximum ratings specify VCC up to 7V, but sustained operation above 6V may degrade reliability or exceed power dissipation limits. For long-term stability, maintain VCC within the 2V–6V specification window defined in the SCHS151C datasheet.

Does CD74HC153M support true bidirectional signal routing?

No, CD74HC153M is a unidirectional 4:1 selector/multiplexer with dedicated input and output terminals. It does not support reverse signal flow or bus transceiver functionality. Each section (1Y and 2Y) sources only from its assigned inputs (1I0–1I3 or 2I0–2I3) and cannot accept data from the output side. For bidirectional applications, external direction-control logic or a dedicated bus switch IC would be required.

Can CD74HC153M operate reliably at -55°C?

Yes, CD74HC153M is fully specified and tested for operation from -55°C to +125°C, as confirmed in the ordering information table and absolute maximum ratings section of the SCHS151C datasheet. This extended temperature range qualifies it for military, aerospace, and industrial applications where ambient conditions fall below commercial-grade limits.

What is the pin 1 orientation for CD74HC153M in tape-and-reel packaging?

For CD74HC153M96.A tape-and-reel packaging, pin 1 is located in Quadrant Q1 of the carrier tape, as documented in TI's PACKAGE MATERIALS INFORMATION sheet. This orientation aligns with JEDEC-standard SOIC tape configuration and ensures consistent automated pick-and-place placement during SMT assembly.

Is CD74HC153M pin-compatible with CD74HCT153M?

Yes, CD74HC153M and CD74HCT153M share identical SOIC-16 pinouts, terminal functions, and physical package dimensions. However, they differ electrically: CD74HC153M uses CMOS input thresholds (VIH = 1.5V min at 2V), while CD74HCT153M uses TTL-compatible thresholds (VIH = 2.0V min). Interchangeability requires verification of driving source logic levels.
