Overview
The SN74LV157ADGVR is a quadruple 2-line to 1-line data selector/multiplexer from the Texas Instruments LV 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. It provides latch-up performance exceeding 100 mA per JESD 78, Class II. The component is housed in a TVSOP-16 package.
Feature Summary
- Provides four independent multiplexing channels for selecting between two data inputs
- Operates across a wide supply voltage range from 2 V to 5.5 V
- Includes an active-low output strobe (G) input for controlling data routing
Applications
- Servers
- LED Displays
- Network Switches
- Telecom Infrastructure
- Motor Drivers
Procurement Notes
Verify the specific ordering suffix 'DGVR' corresponds to the TVSOP-16 package and tape-and-reel carrier configuration. Confirm RoHS compliance status and lead finish details via the manufacturer's current orderable addendum. Ensure the selected variant matches the required moisture sensitivity level and operating temperature range specifications.
Selection Notes
Select this component when a compact quadruple multiplexer is required for systems operating between 2 V and 5.5 V. The TVSOP-16 package offers a space-efficient solution for surface-mount applications. Consider the 7.5 ns propagation delay at 5 V for timing-sensitive signal routing tasks in digital logic circuits.
Part Context
This part belongs to the SN74LV157A family of quadruple 2-line to 1-line data selectors. The 'A' designation indicates updated manufacturing revisions. The 'DGVR' suffix specifies the TVSOP-16 plastic small-outline package with reel packaging. This family is designed for low-voltage CMOS applications requiring high-speed data selection.

FAQ
What is the function of the G pin?
The G pin serves as an active-low output strobe. When G is low, the selected data inputs are routed to the outputs. When G is high, the outputs are disabled.
Can the inputs accept voltages higher than VCC?
Yes, the inputs can accept voltages up to 5.5 V regardless of the VCC supply level, provided VCC does not exceed its maximum rating.
