Overview
The MM74HC4051MTC is an 8-channel analog multiplexer implemented in silicon-gate CMOS technology. It operates with a supply voltage range of 2V to 6V and supports analog signals up to ±6V peak. The device features bidirectional switches with low on-resistance, typically 40Ω at VCC-VEE=4.5V. It includes logic level translation for 5V digital control and ±5V analog signals. Key electrical parameters include a maximum propagation delay of 60ns at 2V and 12ns at 4.5V. The component is housed in a 16-lead Thin Shrink Small Outline Package (TSSOP).
Feature Summary
- Bidirectional analog switching capability allowing any input to function as output.
- Integrated linearization circuitry to lower on-resistance and improve switch linearity.
- Built-in logic level translation enabling 5V logic control with ±5V analog signal ranges.
- Inhibit control terminal that disables all switches when set to high level.
Applications
- Data acquisition systems requiring multi-channel signal selection.
- Audio routing and signal processing circuits.
- Industrial process control instrumentation.
Procurement Notes
Verify the manufacturer origin carefully, as this part number was originally produced by Fairchild Semiconductor. Confirm current availability status through authorized distributors, as production may have transitioned or discontinued. Ensure the TSSOP-16 package variant matches the specific design requirements for board space and thermal management.
Selection Notes
Select this component when designing circuits requiring 8:1 analog signal routing within a compact surface-mount footprint. Verify that the operating voltage range of 2V to 6V aligns with the system power rails. Consider the typical 40Ω on-resistance for signal integrity requirements. Ensure the ±6V analog input range meets the signal amplitude specifications of the application.
Part Context
This device belongs to the MM74HC405x family, which also includes the MM74HC4052 (dual 4-channel) and MM74HC4053 (triple 2-channel) multiplexers. All members share similar CMOS fabrication processes and functional characteristics but differ in channel count and configuration. The MTC suffix specifically denotes the 16-lead TSSOP package format.
Replacement Considerations
Direct pin-compatible replacements include other manufacturers' 74HC4051 variants in TSSOP-16 packages. Verify equivalent on-resistance and leakage current specifications before substitution. Check for differences in logic threshold voltages if interfacing with different digital logic families.
