Product Overview
The TMUX1575 is a Texas Instruments Signal_Chain switch configured as a 4-channel 2:1 SPDT device. It uses EN and SEL logic control pins and supports 1.2 V logic compatibility, with input logic high from 0.8 V to 3.6 V and input logic low from 0 V to 0.45 V.
The switch operates from a recommended 1.08-3.6 V supply. Its signal path supports 0 V to VDD x 2, limited to 3.6 V maximum, and the I/O pins remain rated for 0-3.6 V when VDD is 0 V. Powered-off protection and fail-safe logic allow signal path isolation with VDD = 0 V and permit logic control pins to be driven before the supply pin.
Electrical performance includes 1.7 ohm typical ON-state resistance, 0.1 ohm typical channel match, 1 ohm typical ON-resistance flatness, 1.8 GHz bandwidth, -95 dB OFF isolation at 100 kHz, and -90 dB channel-to-channel crosstalk at 100 kHz. The package is a 16-pin YCJ DSBGA/WCSP measuring 1.4 mm x 1.4 mm, with a recommended 0.1-10 µF decoupling capacitor between VDD and GND.
