TPW4157
Low Voltage 1Ω SPDT Analog Switch
Features
Description
Latch-Up Performance Exceeds 800 mA Per JESD 78,
TPW4157 is high performance Single Pole/Double Throw
Class II
(SPDT) analog switches. The devices feature ultra low RON of
⚫
Supply Voltage: 1.65V to 5.5V
1.15Ω maximum at 4.5V VCC and will operate over the wide VCC
⚫
Low ON-State Resistance: typical 0.95Ω at Vs = 4.5V
⚫
Bandwidth: 100 MHz
⚫
Fast switching times: tON =40 ns, tOFF =15 ns
⚫
Break-Before-Make Switching
⚫
Operation Temperature Range: –40°C to 125°C
⚫
range of 1.65V to 5.5V.
The TPW4157 features very low quiescent current even when
the control voltage is lower than the VCC supply. This feature
services the portable applications very well allowing for the
direct interface with processor general purpose I/Os.
