Overview
The CD74HCT4067ME4 is a single-channel analog multiplexer/demultiplexer manufactured by Texas Instruments. It features a 16:1 configuration, providing sixteen selectable input/output lines controlled by four address inputs. The device operates on a single supply voltage ranging from 4.5 V to 5.5 V. Key electrical parameters include a maximum on-resistance of 180 Ohms and a bandwidth of 89 MHz. Propagation delay is specified at 6 ns, with switch times of 60 ns (on) and 55 ns (off). It supports a wide operating temperature range from -55°C to +125°C and is housed in a 24-pin SOIC package.
Feature Summary
- High-speed CMOS logic technology enabling operation comparable to LSTTL speeds with low power consumption
- Bidirectional switching capability allowing any analog input to function as an output and vice versa
- Direct compatibility with LSTTL logic levels for simplified interface design
- Enable control feature that disables all switches to the off state when driven high
Applications
- Data acquisition systems requiring signal routing
- Industrial process control and automation
- Communication equipment signal gating
- Audio and video signal switching matrices
Procurement Notes
Verify the specific suffix 'E4' against current manufacturer documentation to confirm compliance status and material composition details. Ensure the selected package variant matches the required PCB footprint and thermal management specifications for the target application environment.
Selection Notes
Select this component when a 16-channel analog switch is needed with HCT logic level compatibility. It is suitable for applications requiring bidirectional signal flow within a 4.5 V to 5.5 V supply range. Consider the 180 Ohm on-resistance limit for signal integrity requirements in the specific circuit design.
Part Context
This part belongs to the Texas Instruments CD74HCT4067 family of high-speed CMOS analog multiplexers. It shares functional similarities with the HC series but offers direct LSTTL logic compatibility due to its HCT input structure. The device is designed for general-purpose analog signal routing in digital systems.
Replacement Considerations
Potential substitutes include the CD74HC4067 for HC-level compatibility or the HEF4067BT from Nexperia. Verify pinout compatibility and electrical parameter margins before substitution.
