Overview
The MM74HC4051MTCX is an 8-channel analog multiplexer/demultiplexer fabricated in silicon-gate CMOS technology. It features bidirectional switches with low on-resistance and low off-leakage, supporting analog signals up to ±6V peak with digital control levels of 0 to 6V. The device includes three supply pins (VCC, ground, VEE) for level translation and an inhibit input to disable all switches. It operates within a supply voltage range of 2V to 6V and an ambient temperature range of -40°C to +85°C. Key electrical parameters include a maximum propagation delay of 60 ns at 4.5V, a maximum on-resistance of 160 Ω, and a bandwidth of 30 MHz. It 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.
- Logic level translation enabling 5V logic control for ±5V analog signal ranges.
- Built-in electrostatic discharge protection diodes on all analog and digital inputs.
Applications
- Data acquisition systems requiring multi-channel signal selection.
- Audio routing and signal processing circuits.
- Programmable gain amplifier front ends.
- Test and measurement equipment signal paths.
Procurement Notes
Verify the specific ordering suffix 'X' indicates tape and reel packaging configuration. Confirm that the manufacturer designation aligns with current corporate records, as legacy Fairchild Semiconductor assets are managed by onsemi. Ensure component authenticity through authorized distribution channels given the historical nature of the datasheet.
Selection Notes
Select this component when an 8-channel multiplexing solution with wide analog voltage swing capabilities is required. The TSSOP package suits space-constrained surface-mount designs. Verify that the 160 Ω maximum on-resistance meets system loss requirements compared to lower-resistance alternatives.
Part Context
This part belongs to the MM74HC405x family, which also includes the MM74HC4052 (dual 4-channel) and MM74HC4053 (triple 2-channel) variants. These devices share identical pinouts and core functionality but differ in channel count and internal switch grouping configurations.
Replacement Considerations
Direct pin-compatible replacements include the MM74HC4051WM (Wide SOIC) or MM74HC4051M (Narrow SOIC). Cross-manufacturer equivalents such as the CD74HC4051 may require verification of electrical parameter tolerances and package dimensions.
