1999 Apr 05
853–2152 21177
FEATURES
TTL compatible inputs and outputs
5
switch connection between two port A and port B
Thin shrink small outline (TSSOP)
Undershoot protection included to prevent shoot through level
changes
Bias voltage pre-charges the outputs to minimize signal distortion
during live insertion
DESCRIPTION
The CBT6820 provides twenty bits of high-speed TTL-compatible
bus switching. The low on-state resistance of the switch allows
bi-directional connections to be made while adding near-zero
propagation delay. The device also precharges the B port to a
user-selectable bias voltage (BIASV) to minimize live-insertion
noise.
The device is organized as two 10-bit switch with individual enable
(OE) input. When OE is low, the switch is on and port A is
connected to port B. When OE is high, the switch between port A
and port B is open and the B port is precharged to BIASV through
the equivalent of a 10-k
resistor.
Special clamp circuitry and Schottky diode clamps to ground are
used to prevent an under voltage on the A side (Vin
<
GND) from
causing the B side precharge voltage to drop below the ‘‘1” state.
