74HCT157N,652

Signal Switches, Multiplexers, Decoders Overview

The NXP 74HCT157N,652 is a quad 2-input multiplexer housed in a DIP16 plastic dual in-line package (SOT38-4). It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features non-inverting outputs and includes an active LOW enable input. It complies with JEDEC standard no. 7A and offers ESD protection exceeding 2000 V under the Human Body Model.

Signal Switches, Multiplexers, Decoders Feature Summary

• Quad 2-input multiplexer architecture with common data select and active LOW enable inputs
• Non-inverting data path providing true logic levels at outputs
• High electrostatic discharge protection capability for robust operation

Signal Switches, Multiplexers, Decoders Applications

• Moving data between two groups of registers to four common output buses
• Function generator implementation for irregular logic circuits
• Logic implementation of a 4-pole, 2-position switch

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix '652' against current NXP documentation to confirm packaging and reel specifications. Ensure the DIP16 package variant matches the design requirements. Confirm that the HCT logic family compatibility with Low-power Schottky TTL meets the system interface needs. Check for any recent revision updates to the datasheet that may affect electrical characteristics or pin definitions.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a quad multiplexer with non-inverting outputs is required. The HCT technology ensures compatibility with TTL logic levels while maintaining CMOS low-power dissipation. Verify that the operating voltage range of 4.5 V to 5.5 V aligns with the system power supply. Consider the DIP16 package for through-hole mounting applications requiring high reliability and ease of handling.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74HC/HCT157 series of quad 2-input multiplexers. It is functionally identical to the 74HC158 but provides non-inverting outputs instead of inverted ones. The device is pin-compatible with Low-power Schottky TTL, facilitating easy integration into existing digital designs. It is specified in compliance with JEDEC standard no. 7A for performance consistency.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The 74HC157N is the HC version of this device, offering similar functionality with different voltage thresholds. Other packages such as SO16, SSOP16, TSSOP16, and DHVQFN16 are available for the same logical function if surface-mount technology is preferred. Ensure substitute parts maintain the non-inverting output characteristic and HCT logic level compatibility.
