Overview
The CD74HCT4067M is a single-channel, 16-to-1 analog multiplexer/demultiplexer manufactured by Texas Instruments. It utilizes high-speed CMOS technology to provide bidirectional switching capabilities for analog signals within the supply voltage range. The device operates on a single power supply between 4.5 V and 5.5 V, ensuring direct compatibility with LSTTL logic inputs. Key electrical specifications include a maximum on-resistance of 180 Ohms, a -3 dB bandwidth of 89 MHz, and a propagation delay of 6 ns. It supports an operating temperature range from -55°C to +125°C and is housed in a 24-pin SOIC package.
Feature Summary
- Bidirectional analog signal routing allowing any input to function as output
- High-speed switching with break-before-make timing to prevent short circuits
- Direct logic compatibility with LSTTL standards without level shifting
Applications
- Data acquisition systems requiring multi-channel signal selection
- Programmable gain amplifiers and variable impedance circuits
- Signal gating and modulation in communication equipment
Procurement Notes
Verify the specific suffix 'M' corresponds to the standard 24-SOIC plastic package configuration. Confirm RoHS compliance status through the official datasheet or manufacturer documentation prior to integration. Ensure the ordering part number matches the required tape-and-reel or tube packaging format for production needs.
Selection Notes
Select this component when LSTTL logic interface compatibility is required alongside high-speed analog switching. The HCT variant is suitable for 5 V systems where noise immunity and low static power consumption are priorities. Consider the 180 Ohm on-resistance limit for applications involving higher current loads or strict linearity requirements.
Part Context
This part belongs to the CD74HC(T)4067 family of 16-channel analog switches. It shares functional similarities with the HC variant but differs in voltage tolerance and logic input thresholds. The family is designed for general-purpose signal routing in industrial and commercial electronic systems.
Replacement Considerations
The CD74HCT4067MG4 is a documented alternative offering identical functionality in a 24-SOIC package. Other compatible devices include the Nexperia HEF4067BT series and the onsemi MC14067BDWG, which may require verification of pinout and electrical parameter alignment.
