SN74LVC157ADRG3

Overview

The SN74LVC157ADRG3 is a quadruple 2-line to 1-line data selector/multiplexer from the Texas Instruments LVC logic family. It operates within a supply voltage range of 1.65V to 3.6V and features inputs that accept voltages up to 5.5V, facilitating translation in mixed-voltage systems. The device provides a maximum propagation delay of 5.2ns at 3.3V and includes an active-low output strobe (G) input. It is housed in a 16-pin SOIC package.

Feature Summary

• Operates from 1.65V to 3.6V with inputs accepting voltages up to 5.5V for mixed-system compatibility
• Features a common strobe input that forces all outputs low when asserted high
• Provides ESD protection exceeding 2000V human-body model and 1000V charged-device model ratings

Applications

• Data routing in mixed 3.3V/5V system environments
• High-speed data selection applications requiring low propagation delay
• Portable battery-powered equipment due to low voltage operation

Procurement Notes

Verify the specific ordering suffix 'DRG3' corresponds to the SOIC-16 package with lead finish options as listed in the TI Package Option Addendum. Confirm the moisture sensitivity level and peak reflow temperature requirements align with your assembly process specifications before finalizing procurement.

Selection Notes

Select this component when a quad multiplexer is required for low-voltage digital logic applications. Ensure the design accommodates the 5.5V input tolerance if interfacing with higher voltage sources. Verify that the thermal dissipation characteristics of the SOIC package meet the power budget constraints of the target application environment.

FAQ

How does the G input affect the outputs?

When the G input is high, all outputs are forced low. When G is low, the device selects data from the A or B inputs based on the address select pin.

Can this device interface with 5V logic signals?

Yes, the inputs accept voltages up to 5.5V, allowing the device to function as a translator in mixed 3.3V/5V system environments.
