54LVXC4245

8-Bit Dual Supply Configurable Voltage Interface

Transceiver with TRI-STATE^®Outputs

General Description

Features

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

n Control inputs compatible with TTL level

n Outputs source/sink up to 24 mA

The LVXC4245 is a 24-pin dual-supply, 8-bit configurable

voltage interface transceiver suited for real time configurable

I/O applications. The V_CCApin accepts a 5V supply level.

The “A” port is a dedicated 5V port. The V_CCBpin accepts a

3V-to-5V supply level. The “B” port is configured to track the

n Available in Cerpack and CDIP packages

n Implements patented EMI reduction circuitry

n Flexible V_CCBoperating range

n Allows B port and V_CCBto float simultaneously when OE

is HIGH

_CCBsupply level respectively. A 5V level on the V_CCpin will

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

ure the I/O pins at a 3V level. This device will allow the V_CCB

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 socket that permits live insertion and removal during

normal operation.

n Functionally compatible with the 54 series 245

n Standard Microcircuit Drawing (SMD) 5962-9862001
