M74VHCT157ADTR2G

Overview

The M74VHCT157ADTR2G is a VHCT logic series quad 2-input data selector manufactured by onsemi. It operates within a supply voltage range of 4.5 V to 5.5 V and features four independent circuits in a TSSOP-16 package. Propagation delay is specified at 10 ns at 3.3 V and 8.4 ns at 5 V. The device supports an operating temperature range from -55°C to +125°C.

Feature Summary

• Provides four independent 2-to-1 data selection channels
• Compatible with TTL voltage levels due to VHCT technology
• High-speed signal switching with low propagation delay

Applications

• Data routing in digital systems
• Signal multiplexing for microcontroller interfaces
• Address decoding circuits

Procurement Notes

Verify the component status as the source indicates end-of-life notification dated January 5, 2026. Confirm availability through authorized distributors as stock levels may be limited. Ensure the TSSOP-16 package matches your PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this part when interfacing with 5V TTL logic while requiring CMOS performance. The VHCT series ensures compatibility with standard TTL inputs. Consider the wide industrial temperature range if operating in harsh environments. Verify that the 4.5V to 5.5V supply constraint fits your system design.

Part Context

This component belongs to the MC74VHCT157A series of multiplexers. It is part of onsemi's VHCT logic family, which combines CMOS density with TTL compatibility. The device serves as a direct replacement for similar quad multiplexers in legacy designs requiring high-speed switching capabilities.

Replacement Considerations

Check for pin-compatible alternatives within the same VHCT family. Verify electrical specifications match exactly, particularly propagation delay and supply voltage ranges. Ensure the new component is not subject to similar end-of-life constraints.
