18-BIT UNIVERSAL BUS TRANSCEIVER
WITH 3-STATE OUTPUTS
SCES024J – JULY 1995 – REVISED OCTOBER 2004
To ensure the high-impedance state during power up or power down, OEBA should be tied to V
CC
through a
pullup resistor, and OEAB should be tied to GND through a pulldown resistor; the minimum value of the resistor
is determined by the current-sinking capability of the driver.
Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors
with the bus-hold circuitry is not recommended.
