STG3157

Low voltage low on-resistance SPDT switch

with break-before-make feature

Features

■ High speed:

–tPD = 0.3 ns (max) at VCC = 4.5 V

–tPD = 0.8 ns (max) at VCC = 3.0 V

–tPD = 1.2 ns (max) at VCC = 2.3 V

■ Ultra low power dissipation:

–ICC = 1 µA (max) at TA = 85 °C

■ Low on-resistance; at VIN = 0 V:

–RON = 7 Ω (max TA = 85 °C) at VCC = 4.5 V

–RON = 9 Ω (max TA = 85 °C) at VCC = 3.0 V

■ Wide operating voltage range:

–VCC (OPR) = 1.65 V to 5.5 V single supply

■ TTL threshold ON control input at

VCC = 2.7 to 3.6 V

■ Pin and function compatible with 74 series

3157

■ Latch-up performance exceeds

150 mA (JESD 17)

Description

The STG3157 is a high-speed CMOS analog

SPDT (single-pole double-throw) switch or 2:1

multiplexer/demultiplexer bus switch

manufactured using silicon gate C2MOS

technology. It is designed to operate from a

1.65 V to 5.5 V supply, making the device ideal for

portable applications.

The STG3157 features very low on-resistance

(< 9

Ω) at VCC = 3.0 V. The IN input is provided to

control the SPDT switch, and is compatible with

standard CMOS output. Switch S1 is ON

(connected to common port D) when the IN input

is held high, and OFF (a high impedance state

exists between the two ports) when IN is held low.

Switch S2 is ON (connected to common port D)

when the IN input is held low and OFF (a high

impedance state exists between the two ports)

when IN is held high.

Additional key features are fast switching speed,

break-before-make delay time, and very low

power consumption. All inputs and outputs are

equipped with protection circuits to protect

against static discharge, giving them immunity

from ESD and transient excess voltage.
