74LVC257APW/C5J

Signal Switches, Multiplexers, Decoders Overview

The 74LVC257APW/C5J is a quad 2-input multiplexer manufactured by Nexperia USA Inc. It operates on a single power supply ranging from 1.2 V to 3.6 V and features four independent circuits configured as 2:1 multiplexers. The device provides high noise immunity and CMOS low power consumption. It supports an output drive current of 24 mA for both high and low states. The component is housed in a 16-TSSOP surface-mount package with a width of 4.40 mm. It is rated for operation across an extended temperature range from -40°C to +125°C.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides four independent 2-to-1 multiplexing channels within a single integrated circuit
• Operates reliably with a wide single-supply voltage range from 1.2 V to 3.6 V
• Features Schmitt-trigger inputs to ensure tolerance against slow input rise and fall times
• Supports partial power-down applications through I_OFF circuitry that prevents damaging backflow currents

Signal Switches, Multiplexers, Decoders Applications

• Moving data between two groups of registers to four common output buses
• Function generation for highly irregular logic implementations
• Signal routing in mixed 3.3 V and 5 V environments

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix /C5J against official Nexperia documentation to confirm it denotes a valid manufacturing variant or marking code rather than a generic distributor designation. Ensure compatibility with standard 16-TSSOP footprints during procurement planning. Confirm RoHS3 compliance status directly with the manufacturer or authorized distributors prior to finalizing orders.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when designing systems requiring multiple independent signal paths controlled by a common select line. It is suitable for applications needing direct interface with TTL levels while operating at lower voltages. Consider the 16-TSSOP package constraints for board space. Verify that the required output drive capability meets the load requirements of the destination circuits.
