UNISONIC TECHNOLOGIES CO., LTD US5C3257 Preliminary CMOS IC QUAD 2:1 MUX/DEMUX BUS SWITCH DESCRIPTION The UTC US5C3257 is a QUAD 2:1 multiplexer/demultiplexer with low on-resistance and is pinout and function compatible with the TTL device. Inputs can be connected to outputs with low on resistance (5Ω) with no additional ground bounce noise or propagation delay. FEATURES * 5Ω switches connect inputs to outputs * ESD protection on pin * Near zero propagation delay * Ultra Low Quiescent Power (0.2µA Typical) –Ideally suited for notebook applications * Direct bus connection when switches are ON * Pin compatible with U74 series logic devices ORDERING INFORMATION Ordering Number Lead Free Halogen Free US5C3257L-S16-R US5C3257G-S16-R US5C3257L-S16-T US5C3257G-S16-T Note: xx: Output Voltage, refer to Marking Information. www.unisonic.com.tw Copyright © 2013 Unisonic Technologies Co., Ltd Package Packing SOP-16 SOP-16 Tape Reel Tube 1 of 6 QW-R502-891.a US5C3257 Preliminary PIN CONFIGURATION PIN DESCRIPTION PIN NO. 1 2, 3, 5, 6, 10, 11,13,14, 4, 7, 9, 12 8 15 16 PIN NAME S DESCRIPTION Select Inputs IAn-IDn Data Inputs YA-YD GND Data Outputs Ground Enable E VCC CMOS IC Power UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 6 QW-R502-891.a US5C3257 Preliminary CMOS IC BLOCK DIAGRAM IA0 IA1 IB1 IB0 IC1 IC0 ID1 ID0 E S YA YC YB YD TRUTH TABLE E S YA YB YC YD Function H X Hi-Z Hi-Z Hi-Z Hi-Z Disable L L IA0 IB0 IC0 ID0 S=0 L H IA1 IB1 IC1 ID1 S=1 Note: H=High Voltage Level, L=Low Voltage Level UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 3 of 6 QW-R502-891.a US5C3257 Preliminary CMOS IC ABSOLUTE MAXIMUM RATING PARAMETER SYMBOL RATINGS UNIT Supply Voltage to Ground Potential (Inputs & VCC Only) -0.5~+7.0 V Supply Voltage to Ground Potential (Outputs & D/O Only) -0.5~+7.0 V DC Input Voltage -0.5~+7.0 V DC Output Current 120 mA Power Dissipation PD 0.5 W Storage Temperature TSTG -55~+150 °C Ambient Temperature with Power Applied TOPR -40~+85 °C Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.

Typical values are at VCC=5.0V, TA=25°C ambient and maximum loading. 2. Not more than one output should be shorted at one time. Duration of the test should not exceed one second. 3. Measured by the voltage drop between I and Y pin at indicated current through the switch. ON resistance is determined by the lower of the voltages on the two (I, Y) pins. 4. This parameter is determined by device characterization but is not production tested.
