IDT74CBTLV3257 LOW-VOLTAGE QUAD 2:1 MUX/DEMUX BUS SWITCH INDUSTRIAL TEMPERATURE RANGE LOW-VOLTAGE QUAD 2:1MUX/DEMUX BUS SWITCH FEATURES: − − − − − − − − Functionally equivalent to QS3257 5Ω Switch Connection between Two Ports Isolation Under Power-Off Conditions Over-voltage tolerant Latch-up performance exceeds 100ma VCC = 2.3V - 3.6V, normal range ESD > 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200pF, R = 0) Available in SSOP, QSOP, and TSSOP packages IDT74CBTLV3257 DESCRIPTION: The CBTLV3257 is a quad 2:1 multiplexer/demultiplexer. The low onstate resistance of the switch allows connections to be made with minimal propagation delay. The select (S) input controls the data flow. The multiplexers/demultiplexers are enabled when the output-enable ( OE) input is low. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
