    產(chǎn)品信息

    The 74LVXC3245 is a 24-pin dual-supply, octal configurable voltage interface transceiver especially well suited for PCMCIA and other real time configurable I/O applications. The V
    pin accepts a 3V supply level; the A port is a dedicated 3V port. The V
    pin accepts a 3V-to-5V supply level. The B port is configured to track the V
    supply level. A 5V level on the V
    pin will configure the I/O pins at a 5V level and a 3V V
    will configure the I/O pins at a 3V level. The A port interfaces with a 3V host system and the B port to the card slots. This device will allow the V
    voltage source pin and I/O pins on the B port to float when OE is High. This feature is necessary to buffer data to and from a PCMCIA socket that permits PCMCIA cards to be inserted and removed during normal operation. The Transmit/Receive (T/R) input determines the direction of data flow. Transmit (active-High) enables data from the A port to B port. Receive (active-Low) enables data from the B port to the A port.
    • Bidirectional Interface Between 3V and 3V/5V Buses
    • Control Inputs Compatible with TTL Level
    • Outputs Source/Sink Up to 24mA
    • Guaranteed Simultaneous Switching Noise Level and Dynamic Threshold Performance
    • Available in SOIC and TSSOP Packages
    • Flexible V
    • Operating Range
    • Allows B Port and V
    • to Float Simultaneously When OE Is High
    • Functionally Compatible with the 74 Series 245 PIN Pins OE T/R A0-A7 B0-B7
    • Pb-Free Packages are Available*
