74LVC1G3157GW

The 74LVC1G3157GW from NXP Semiconductors is a high-speed, low-power, low-voltage Si-gate CMOS device functioning as a 2-channel analog multiplexer/demultiplexer. It includes one digital select input (S), two independent inputs/outputs (Y0, Y1), and a common input/output (Z).

This device operates across a wide supply voltage range from 1.65 V to 5.5 V. It offers very low ON resistance, with typical values of 7.5 Ω at 2.7 V, 6.5 Ω at 3.3 V, and 6 Ω at 5 V. The switch current capability is 32 mA, and it features break-before-make switching for reliable operation.

The 74LVC1G3157GW is specified for operation in temperature ranges from -40 °C to +85 °C and -40 °C to +125 °C. It is available in multiple package options, including SOT363, SOT457, SOT886, and SOT891, all of which are surface-mounted types.

Key electrical characteristics include high noise immunity and TTL interface compatibility at 3.3 V. The Schmitt trigger action on the select input provides tolerance for slower input rise and fall times. ESD protection is provided, exceeding 2000 V for HBM and 200 V for MM.
