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
