8-Bit Dual Supply Configurable Voltage Interface

Transceiver with 3-STATE Outputs

General Description

The LVXC3245 is a 24-pin dual-supply, 8-bit configurable

voltage interface transceiver suited for PCMCIA and other

real time configurable I/O applications. The V_CCApin

Features

■ Bidirectional interface between 3V and 3V-to-5V buses

■ Control inputs compatible with TTL level

■ Outputs source/sink up to 24 mA

accepts a 3V supply level. The A Port is a dedicated 3V

port. The V_CCBpin accepts a 3V-to-5V supply level. The B

■ Guaranteed simultaneous switching noise level and

dynamic threshold performance

Port is configured to track the V_CCBsupply level respec-

tively. A 5V level on the V_CCpin will configure the I/O pins

at a 5V level and a 3V V_CCwill configure the I/O pins at a

■ Implements patented EMI reduction circuitry

■ Flexible V_CCBoperating range

■ Allows B Port and V_CCBto float simultaneously when OE

is HIGH

3V level. The A Port should interface with a 3V host system

and the B Port to the card slots. This device will allow the

V_CCBvoltage source pin and I/O pins on the B Port to float

■ Functionally compatible with the 74 series 245

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.
