DESCRIPTION

· The 74LVC1G3157 is a single-pole double-throw analog switch with a digital select input (S), two independent inputs/outputs (Y0 and Y1), and a common input/output (Z).
· It supports control inputs from both 3.3 V and 5 V devices, making it suitable for mixed voltage environments.
· Features Schmitt-trigger action at control inputs for tolerance to slower input rise and fall times.

FEATURES

· Wide supply voltage range from 1.65 V to 5.5 V.
· Very low ON resistance: 7.5 Ω at 2.7 V, 6.5 Ω at 3.3 V, and 6 Ω at 5 V.
· Supports up to 32 mA continuous switch current.
· Break-before-make switching ensures no short-circuit during switching.
· High noise immunity and CMOS low power dissipation.
· TTL interface compatibility at 3.3 V.
· Latch-up performance meets JESD 78 Class I requirements.
· Overvoltage tolerant control inputs up to 5.5 V.
· ESD protection: HBM exceeds 2000 V, CDM exceeds 1000 V.
· Available in multiple package options.
· Operating temperature range from -40 °C to +125 °C.

APPLICATIONS

· Suitable for use in mixed 3.3 V and 5 V environments as voltage translators.
· Ideal for applications requiring low ON resistance and high current handling.
· Used in systems where noise immunity and low power dissipation are critical.
· Applicable in scenarios requiring robust ESD protection and overvoltage tolerance.
