TS12A4515数据手册TI中文资料规格书

描述 Description

The TS12A4514/TS12A4515 are single pole/single throw (SPST), low-voltage, single-supply CMOS analog switches, with very low switch ON-state resistance. The TS12A4514 is normally open (NO). The TS12A4515 is normally closed (NC). These CMOS switches can operate continuously with a single supply between 2 V and 12 V. Each switch can handle rail-to-rail analog signals. The OFF-leakage current maximum is only 1 nA at 25°C or 10 nA at 85°C. All digital inputs have 0.8-V to 2.4-V logic thresholds, ensuring TTL/CMOS-logic compatibility when using a 5-V supply. For pin-compatible parts for use with dual supplies, see the TS12A4516/TS12A4517.
