Texas Instruments TMUX1511 1:1 SPST 4-Channel Analog Switch
Texas Instruments TMUX1511 1:1 SPST 4-Channel Analog Switch is a complementary metal-oxide-semiconductor (CMOS) switch. The TMUX1511 offers a 1:1 SPST switch configuration with four independently controlled channels. A wide operating supply of 1.5V to 5.5V allows for use in various applications, from servers and communication equipment to industrial applications. The device supports bidirectional analog and digital signals on the source (Sx) and drain (Dx) pins and can pass signals above supply up to VDD x 2, with a maximum input/output voltage of 5.5V.
Powered-off Protection up to 3.6V on the signal path of the Texas Instruments TMUX1511 provides isolation when the supply voltage is removed (VDD = 0V). Without this protection feature, switches can back-power the supply rail through an internal ESD diode and cause potential damage to the system. Fail-Safe Logic circuitry allows voltages on the logic control pins to be applied before the supply pin, protecting the device from potential damage. All logic control inputs have 1.8V logic-compatible thresholds, ensuring both TTL and CMOS logic compatibility when operating in the valid supply voltage range.
