描述 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 CMOS technology. It is designed to operate from a 1.65 V to 5.5 V supply, making the device ideal for portable applications.

特性 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)
