............................................................................................................................................................ SCES463E – JUNE 2003 – REVISED APRIL 2008
SINGLE-POLE DOUBLE-THROW ANALOG SWITCH
• Qualified for Automotive Applications • Rail-to-Rail Signal Handling
• ESD Protection Exceeds 2000 V Per • High Degree of Linearity
MIL-STD-883, Method 3015; Exceeds 200 V
• High Speed, Typically 0.5 ns
Using Machine Model (C = 200 pF, R = 0)
(V
CC
= 3 V, C
L
= 50 pF)
• 1.65-V to 5.5-V V
CC
Operation
• Low On-State Resistance, Typically ≈ 6 Ω
• Useful for Both Analog and Digital (V
CC
= 4.5 V)
Applications
• Latch-Up Performance Exceeds 100 mA Per
• Specified Break-Before-Make Switching JESD 78, Class II
This single-pole double-throw (SPDT) analog switch is designed for 1.65-V to 5.5-V V
CC
operation.
The SN74LVC1G3157 can handle both analog and digital signals. The device permits signals with amplitudes of
up to V
CC
(peak) to be transmitted in either direction.
Applications include signal gating, chopping, modulation or demodulation (modem), and signal multiplexing for
analog-to-digital and digital-to-analog conversion systems.
