74HC157TELL-E

Signal Switches, Multiplexers, Decoders Overview

The Renesas 74HC157TELL-E is a high-speed CMOS quad 2-input multiplexer. It features four independent 2:1 data selectors with common select and enable inputs. The device operates within a voltage range of 2.0 to 6.0 V, providing standard I/O performance compatible with LSTTL loads. Typical propagation delay is 12 ns at 5 V with 50 pF load. It offers low quiescent supply current and high output drive capability.

Signal Switches, Multiplexers, Decoders Feature Summary

• Quad 2-input multiplexing architecture with common selection control
• True (non-inverted) output logic state matching selected input
• Active-low enable input for global output control
• CMOS technology ensuring low static power consumption

Signal Switches, Multiplexers, Decoders Applications

• Data routing between multiple register banks to a common bus
• Function signal generation circuits
• Digital system data path selection
• Logic level translation interfaces

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix 'TELL-E' against official Renesas documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with required operating temperature ranges and RoHS compliance standards before procurement. Cross-reference part numbers with authorized distributors to avoid obsolete or counterfeit components.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a quad 2-to-1 multiplexer with non-inverted outputs is required. It serves as an alternative to the 74HC158, which provides inverted outputs. Consider the 2V to 6V operating range and 12 ns typical delay for speed requirements. Verify pinout compatibility with existing PCB layouts designed for standard 16-pin DIP or SOIC packages.

Signal Switches, Multiplexers, Decoders Part Context

The 74HC157 belongs to the Renesas HC/UH series of high-speed CMOS logic devices. This family is pin-compatible with Low-Power Schottky TTL (LSTTL) standards, facilitating integration into legacy digital systems. The device adheres to JEDEC Standard No. 7A, ensuring broad industry interoperability and standardized electrical characteristics across manufacturers.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The HD74HC158 is functionally identical but provides inverted outputs. For direct replacement, verify that the application tolerates true logic levels rather than complemented signals. Other generic 74HC157 equivalents from different manufacturers may be used if pinouts and electrical parameters match.
