74HC257N,652

Signal Switches, Multiplexers, Decoders Overview

The 74HC257N,652 is a high-speed Si-gate CMOS quad 2-input multiplexer with 3-state outputs. It selects 4 bits of data from two sources controlled by a common select input (S). Data appears at the outputs in true form when OE is LOW. The device operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range of -40 °C to +125 °C. Propagation delay is typically 11 ns at 5.0 V with 15 pF load capacitance.

Signal Switches, Multiplexers, Decoders Feature Summary

• Non-inverting data path provides true output signals
• 3-state outputs interface directly with system bus
• ESD protection exceeds 2000 V per HBM standard

Signal Switches, Multiplexers, Decoders Applications

• Data routing between multiple sources
• System bus interfacing
• Logic implementation of 4-pole, 2-position switches

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure package compatibility and availability status. Confirm that the component meets all required environmental specifications for the intended operating conditions before finalizing procurement decisions.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component for applications requiring non-inverting multiplexing with 3-state control. Ensure the design accommodates the specified supply voltage limits and thermal derating requirements. Verify pin compatibility with Low-power Schottky TTL systems if direct replacement is considered.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74HC series of logic integrated circuits manufactured by NXP Semiconductors. It is functionally identical to the 74HC258 except for its non-inverting output configuration. The device is designed for general-purpose digital logic applications requiring high-speed data selection capabilities.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The 74HC258 is a functional substitute with inverted outputs. Other manufacturers produce equivalent quad 2-input multiplexers with 3-state outputs; verify pinout and electrical characteristics match the original specification.
