74VHC153MTC

Signal Switches, Multiplexers, Decoders Overview

The onsemi 74VHC153MTC is a dual 4-input multiplexer housed in a 16-lead Thin Shrink Small Outline Package (TSSOP). It operates within a supply voltage range of 2.0 V to 5.5 V and supports an operating temperature from -40°C to +85°C. Propagation delays are specified at 15.4 ns maximum at 3.3 V with 50 pF load, and 9.7 ns maximum at 5.0 V with 50 pF load. The device features common select inputs and individual active-LOW enables for each section.

Signal Switches, Multiplexers, Decoders Feature Summary

• Dual independent 4-to-1 multiplexing sections with common select lines
• Individual active-LOW enable inputs for independent output strobing
• Power-down protection on all inputs to prevent device destruction during mismatched supply voltages
• Pin and function compatibility with standard 74HC153 devices

Signal Switches, Multiplexers, Decoders Applications

• Data routing between multiple sources to a single destination
• Function generation for logic circuits requiring two functions of three variables
• System interfacing between 5V and 3V logic levels or battery backup systems

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific package variant against design requirements, as the MTC suffix denotes the TSSOP form factor. Confirm that the component meets RoHS compliance standards if required by the manufacturing process. Ensure that unused inputs are properly terminated to HIGH or LOW states to maintain operational stability and prevent floating signal issues.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when dual independent multiplexing is required within a compact surface-mount footprint. The low power dissipation characteristics make it suitable for applications where energy efficiency is critical. Verify that the propagation delay specifications meet the timing constraints of the target system clock speeds.
