www.ti.com SCLS605D – DECEMBER 2004 – REVISED JULY 2013 OCTAL BUS TRANSCEIVER
WITH 3-STATE OUTPUTS
Check for Samples: SN74LV245AT FEATURES DESCRIPTION This octal bus transceiver is designed for
asynchronous two-way communication between data
buses. The control-function implementation minimizes
external timing requirements. 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.
This device is fully specified for partial-power-down
applications using Ioff. The Ioff circuitry disables the
outputs, preventing damaging current backflow
through the device when it is powered down. DB, DGV, DW, NS, OR PW PACKAGE
