RS2254XQ

RS2254 CMOS Quad Bilateral Analog Switch FEATURES • -3dB Bandwidth: 180MHz • Single Supply Operation +2.5V to +5.5V • Low ON Resistance, 24Ω(TYP) With 5V Supply • High Off-Isolation: -83dB (RL = 50Ω, f = 1MHz) DESCRIPTION The RS2254 device is a CMOS analog IC configured as quad bilateral single-pole/single-throw (SPST) switches. It intended for the transmission or multiplexing of analog or digital signals. This CMOS device can operate from 2.5 V to 5.5 V. • Guaranteed On-Resistance Match Between Channels • Extremely Low Off-State Switch Leakage: 1nA (TYP) at 25°C • Operating Temperature Range: -40°C to +125°C • PACKAGES: SOIC-14(SOP14) and TSSOP-14 The RS2254 device consists of four bilateral switches, each with independent controls. It has low on-resistance (24Ω TYP) and very low off-leakage current (1nA TYP). The RS2254 is available in Green SOIC-14 and TSSOP-14 packages. It operates over an ambient temperature range of -40°C to +125°C.
