STG3157 数据手册 ( 数据表 ) - STMicroelectronics

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.

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)
