Texas Instruments SN74LVC157A/SN74LVC157A-Q1 Data Multiplexers

Texas Instruments SN74LVC157A/SN74LVC157A-Q1 Data Selectors/Multiplexers are 2-line to 1-line devices with four channels. These digital data selectors/multiplexers feature <0.8V typical VOLP (output ground bounce) at VCC=3.3V, TA=25°C and >2V typical VOHV (output VOH undershoot) at VCC=3.3V, TA=25°C. The SN74LVC157A-Q1 data selectors/multiplexers are qualified for automotive applications and are designed to operate within the 2.7VCC to 3.6VCC voltage range.
