TI TMUX1308QBQBRQ1

TMUX1308-Q1 and TMUX1309-Q1 are general-purpose CMOS MUX devices. The TMUX1308-Q1 is an 8:1 single-channel (single-ended) MUX, while the TMUX1309-Q1 is a 4:1 dual-channel (differential) MUX. These devices support bidirectional analog and digital signals ranging from GND to VDD on the source (Sx) and drain (Dx) pins. The TMUX13xx-Q1 devices feature an internal injection current control function, eliminating the need for external diode and resistor networks (typically used to protect switches and keep input signals within the supply voltage range). The internal injection current control circuit allows signals on disabled signal paths that exceed the supply voltage to be blocked without affecting signals on enabled signal paths. In addition, the TMUX13xx-Q1 devices have no internal diode paths to the supply pins, eliminating the risk of damaging components connected to the supply pins or inadvertently powering supply rails. All logic inputs feature 1.8 V logic-compatible thresholds, which ensure TTL and CMOS logic compatibility when operating within valid supply voltage ranges. A failsafe logic circuit allows voltage to be applied to the control pins before the supply pins, protecting the device from potential damage.
