SN74LV157ANS

Overview

The SN74LV157ANS is a quadruple 2-line to 1-line data selector/multiplexer from the SN74LV157A series. It operates within a supply voltage range of 2 V to 5.5 V and accepts input voltages up to 5.5 V. The device features a maximum propagation delay of 7.5 ns at 5 V and includes an active-low output strobe (G) input. It provides true data outputs and is designed for robust performance with latch-up characteristics exceeding 100 mA per JESD 78, Class II.

Feature Summary

• Operates across a wide supply voltage range from 2 V to 5.5 V
• Inputs accept voltages up to 5.5 V for compatibility
• Includes active-low output strobe control
• Provides true non-inverted data outputs

Applications

• Servers
• LED Displays
• Network Switches
• Telecom Infrastructure
• Motor Drivers

Procurement Notes

Verify the specific package suffix 'NS' corresponds to the SOP-16 configuration required for your design. Confirm that the operating temperature range of -40°C to +85°C aligns with your environmental specifications. Ensure input signals do not exceed the absolute maximum ratings to prevent damage. Check the latest orderable addendum for current production status and availability details.

Selection Notes

Select this component when a quadruple multiplexer is needed with inputs compatible with 5.5 V logic levels while operating on lower supply voltages. The LV157A offers faster switching speeds compared to standard LV devices. Consider the SOP-16 package constraints regarding board space and thermal dissipation requirements for your specific application layout.

FAQ

How does the output strobe (G) pin function?

The G pin is an active-low output strobe. When G is high, all outputs are forced low regardless of other inputs. When G is low, the selected data inputs are routed to the outputs.

What is the latch-up performance rating?

The latch-up performance exceeds 100 mA per JESD 78, Class II, ensuring robust protection against latch-up events under specified test conditions.
