12-BIT TO 24-BIT REGISTERED BUS EXCHANGER
WITH 3-STATE OUTPUTS
SCES019N – JULY 1995 – REVISED JULY 2004
To ensure the high-impedance state during power up or power down, a clock pulse should be applied as soon as
possible, and 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. Due to OE being routed through a register, the active state of the
outputs cannot be determined before the arrival of the first clock pulse.
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.
