TMUX1237

SCDS424A –DECEMBER 2019–REVISED MARCH 2020

TMUX1237 3-Ω Low R , 5-V, 2:1 (SPDT) General Purpose Switch

With No Overshoot When Switching Inputs

1 Features

3 Description

The TMUX1237 is a general purpose 2:1, single-pole

•

No Overshoot When Switching Inputs

Rail-to-rail Operation

double-throw (SPDT), switch that supports a wide

operating range of 1.08 V to 5.5 V. The device

supports bidirectional analog and digital signals on

the source (Sx) and drain (D) pins ranging from GND

to V_DD. The state of the select pin (SEL) controls

which of the two sources pins are connected to the

drain pin. Additionally, the TMUX1237 has a low

supply current of 7 nA which enables the device to be

used in a host of handheld or low power applications.

Bidirectional Signal Path

1.8 V Logic Compatible

Fail-safe Logic

Low On-resistance: 3 Ω

Wide Supply Range: 1.08 V to 5.5 V

-40°C to +125°C Operating Temperature

Low Supply Current: 7 nA

Break-before-make Switching

ESD Protection HBM: 2000 V

The TMUX1237 improves system reliability by

eliminating overshoot that might occur in a system

due to switching between two voltage levels on the

source (Sx) pins. In addition, the TMUX1237 also

maintains fast switching times, enabling it to improve

system performance for a wide range of applications

from communications equipment to building

automation.

2 Applications

•

Analog and Digital Switching

I²C and SPI Bus Multiplexing

Remote Radio Units (RRU)

Active Antenna System mMIMO (AAS)

Rack Server

All logic inputs have 1.8

logic compatible

thresholds, ensuring both TTL and CMOS logic

compatibility when operating in the valid supply

voltage range. Fail-Safe Logic circuitry allows

voltages on the control pins to be applied before the

supply pin, protecting the device from potential

damage.
