Overview
The MC74LVXT4051MEL is an analog multiplexer/demultiplexer manufactured by onsemi, utilizing high-performance silicon-gate CMOS technology. It features a single-pole eight-throw (SP8T) configuration with three digital channel-select inputs and an active-high enable pin. The device operates within a digital supply voltage range of 2.5 V to 6.0 V and supports analog signals across the full power supply range from VCC to VEE. Key electrical parameters include a maximum propagation delay of 40 ns at 2.5 V, a typical bandwidth of 80 MHz, and a maximum ON resistance of 86 Ω at 3.0 V. It offers low leakage current, improved linearity, and break-before-make switching characteristics.
Feature Summary
- Utilizes silicon-gate CMOS technology for fast propagation speeds and low ON resistance.
- Features over-voltage tolerant (OVT) control inputs compatible with standard TTL levels.
- Supports both single-supply operation (VEE = GND) and split supplies up to ±3.0 V.
- Incorporates break-before-make circuitry to prevent signal shorting during switching.
Applications
- Signal routing in data acquisition systems
- Audio and video signal switching applications
- Level translation between 3.0 V logic and higher voltage analog domains
Procurement Notes
Verify the specific ordering suffix 'MEL' corresponds to the SOEIAJ-16 package with 2000-unit tape and reel shipping. Confirm RoHS compliance status via the 'G' suffix variant if lead-free components are required. Cross-reference the datasheet revision date to ensure alignment with current manufacturing specifications.
Selection Notes
Select this component when an 8-channel analog switch is required with TTL-compatible digital control interfaces. Ensure the application voltage does not exceed the 6.0 V maximum limit for both digital and analog sections. Consider the thermal resistance and power dissipation limits if operating near the upper temperature extremes.
Part Context
This part belongs to the MC74LVXT4051 series, which includes variants in SOIC-16, TSSOP-16, and SOEIAJ-16 packages. The M suffix denotes the SOEIAJ-16 package type, while the EL suffix indicates the specific tape and reel packaging quantity. It serves as a direct replacement for legacy metal-gate devices like the MC14051B in modern low-voltage designs.
Replacement Considerations
Public confirmed substitute part numbers include MC74LVXT4051DR2G and MC74LVXT4051DTG. Verify pinout compatibility with HC4051A or LVX8051 equivalents if migrating from older designs. Ensure the replacement package matches the PCB footprint requirements.
