U74CBT3126

UNISONIC TECHNOLOGIES CO., LTD U74CBT3126 QUADRUPLE FET BUS SWITCH  DESCRIPTION The U74CBT3126 is a quadruple line bus switch. It is composed of four 1-bit line switchs with independent separate output-enable (OE) inputs. When OE is low, the switch is disabled. To ensure the high-impedance state during power up or power down, OE should be tied to GND through a pull-down resistor and the minimum value of the resistor is determined by the current-sourcing capability of the driver.  FEATURES * 5 Ω switch connection between two ports * Max tpd of 0.25 ns at 5V * Low power consumption, ICC = 3 μA (Max.) at 5.5V * TTL compatible input levels CMOS IC  ORDERING INFORMATION Ordering Number U74CBT3126G-S14-R U74CBT3126G-P14-R Package SOP-14 TSSOP-14 Packing Tape Reel Tape Reel  MARKING www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd 1 of 5 QW-R502-567.B U74CBT3126  PIN CONFIGURATION 1OE 1A 1B 2OE 2A 2B GND 1 2 3 4 5 6 7  FUNCTION TABLE (each bus switch) INPUT OE L H FUNCTION Z A=B  LOGIC DIAGRAM (positive logic) 1 1OE 2 1A 4 2OE 5 2A 3OE 10 9 3A 13 4OE 12 4A 14 VCC 13 4OE 12 4A 11 4B 10 3OE 9 3A 8 3B 3 1B 6 2B 8 3B 11 4B CMOS IC UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 5 QW-R502-567.B U74CBT3126 CMOS IC  ABSOLUTE MAXIMUM RATING (TA =25°C , unless otherwise specified) PARAMETER SYMBOL RATINGS UNIT Supply Voltage VCC -0.5~7 V Input Voltage VIN -0.5~7 V Supply Voltage VCC 4 ~ 5.5 V Control Input Voltage Hi...
