74AC157MTC

Signal Switches, Multiplexers, Decoders Overview

The onsemi 74AC157MTC is a quad 2-input multiplexer housed in a 16-lead Thin Shrink Small Outline Package (TSSOP). It operates within a supply voltage range of 2.0V to 6.0V and supports an operating temperature from -40°C to +85°C. The device features four outputs that source or sink up to 24 mA. Propagation delays are specified at 8.5 ns maximum at 3.3V and 6.5 ns maximum at 5.0V.

Signal Switches, Multiplexers, Decoders Feature Summary

• Quad 2-input multiplexer architecture with common select and enable inputs
• Outputs provide true noninverted data selection
• Capable of functioning as a function generator for two variables

Signal Switches, Multiplexers, Decoders Applications

• Transferring data between register groups to common output buses
• Implementing gating functions via logic equation generation
• Selecting specific data bits from multiple sources

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the package designation MTC16 corresponds to the required 16-lead TSSOP footprint. Confirm the AC logic family specifications align with system voltage requirements, specifically the 2.0V to 6.0V operating range. Ensure input thresholds match the driving circuit levels. Check datasheet notes regarding absolute maximum ratings to prevent damage during operation.

Signal Switches, Multiplexers, Decoders Selection Notes

Choose this component when high-speed switching between two data sources is required for four parallel lines. The AC series offers reduced quiescent current compared to older families. Verify that the 24 mA output drive capability meets load requirements. Consider the ACT variant if TTL-compatible input thresholds are necessary for the application environment.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74AC157 series of quad multiplexers originally developed by Fairchild Semiconductor. The 'MTC' suffix identifies the specific 16-lead Thin Shrink Small Outline Package. The device implements a 4-pole, 2-position switch controlled by a single Select input and an active-LOW Enable input.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The 74ACT157MTC serves as a direct functional substitute within the same package, offering TTL-compatible input thresholds while maintaining the same pinout and physical dimensions.
