TC7USB221FT

TC7USB221FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7USB221FT Dual SPDT USB Switch TC7USB221 is high-speed CMOS dual 1-2 multiplexer /demultiplexer. The low on resistance and the low capacitance of the switch allow connections to USB application. This device consists of dual individual two-inputs multiplexer/demultiplexer with common select input (S) and output enable ( OE ). The D+/D- inputs is connected to the D1+/D1- or D2+/D2- outputs determined by the combination both the select input (S) and output enable ( OE ). When the output enable ( OE ) input is held “H” level, the switches are open with regardless the state of select inputs and a high-impedance state exists between the switches. All inputs are equipped with protection circuits against static discharge. Features Operating voltage:VCC = 2.3 to 3.6 V ON-capacitance: CI/O = 7 pF Switch ON (typ.) @VCC=3.3 V ON-resistance: RON = 6.5 Ω (typ.) @ VCC=3 V, VI/O=0 V RON Flatness: RON(flat) = 1.6 Ω (typ.) @ VCC=3 V Delta RON: ΔRON = 0.5 Ω (typ.) @ VCC=3 V ESD performance: Machine model ≥ ± 200 V Human body model ≥ ± 2000 V Power-down protection for inputs ( OE and S, I/O) Package: TSSOP14 TC7USB221FT Weight TSSOP14-P-0044-0.65A: 0.06 g (typ.)
