74CBTLV3251 LOW-VOLTAGE 8:1 MULTIPLEXER/DEMULTIPLEXER INDUSTRIAL TEMPERATURE RANGE LOW-VOLTAGE 74CBTLV3251 8:1 MULTIPLEXER/ DEMULTIPLEXER FEATURES: DESCRIPTION: Functionally equivalent to QS3251 The CBTLV3251 is a 1-of-8 high-speed multiplexer/demultiplexer. The 5 bi-directional switch connection between two ports low on-state resistance of the switch allows connections to be made with Isolation under power-off conditions minimal propagation delay. Over-voltage tolerant The select input (S0, S1, S2) controls the data flow. The multiplexer/ Latch-up performance exceeds 100mA demultiplexer switches are disabled when the output-enable (OE) input is VCC = 2.3V - 3.6V, Normal Range high. ESD > 2000V per MIL-STD-883, Method 3015 To ensure that the device is in high-impedance state during power up or > 200V using machine model (C = 200pF, R = 0) power down, OE should be tied to VCC through a pullup resistor the minimum Available in QSOP and TSSOP packages value of the resistor is determined by the current-sinking capability of the driver.
