UNISONIC TECHNOLOGIES CO., LTD US5C3306 Preliminary CMOS IC 2-BIT BUS SWITCH WITH ACTIVE LOW ENABLES DESCRIPTION The UTC US5C3306 consist of two independent 5Ω switches with fast individual enables. The “A” pin is connected to the “B” pin directly when the associated Bus Enable (BE) pin is set to “Low”. The bus switch introduces no additional propagation delay or additional ground bounce noise. FEATURES * Low on-resistor between two ports (5Ω typical) * Near-Zero propagation delay * Direct bus connection when switches are ON * Ultra Low Quiescent Power (0.2μA typical) - Ideally suited for notebook applications ORDERING INFORMATION Ordering Number US5C3306G-SM1-R Package MSOP-8 Packing Tape Reel MARKING www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd 1 of 6 QW-R121-026.a US5C3306 CMOS IC PIN CONFIGURATION BE1 1 8 VCC A1 2 7 BE2 B1 3 6 B2 GND 4 5 A2 PIN DESCRIPTION PIN NO. 1, 7 2, 5 3, 6 4 8 Preliminary PIN NAME BEn A1, A2 B1, B2 GND VCC DESCRIPTION Switch Enable Bus A Bus B Ground Power TRUTH TABLE (Note 1) An Bn BE n X (Note 2) Hi-Z Hi-Z H Hi-Z Hi-Z L Bn An Notes: 1.

This parameter is guaranteed but not tested on Propagation Delays. 2. The bus switch contributes no propagational delay other than the RC delay of the On-Resistance of the switch and the load capacitance. The time constant for the switch alone is of the order of 0.25ns for 50pF load. Since this time constant is much smaller than the rise/fall times of typical driving signals, it adds very little propagational delay to the system. Propagational delay of the bus switch when used in a system is determined by the driving circuit on the driving side of the switch and its interaction with the load on the driven side. 3. RP terminates to 7V supply for tPZL and tPLZ measurement.
