Philips Semiconductors
10-bit bus switch with precharged outputs
for live insertion
Product specification
CBT6800
FEATURES
5 switch connection between two ports
TTL compatible input and output levels
Outputs are precharged by bias voltage to minimize signal
distortion during live insertion
Latch-up protection exceeds 100 mA per JESD78
ESD protection exceeds 2000 V HBM per JESD22-A114,
200 V MM per JESD22-A115 and 1000 V CDM per JESD22-C101
DESCRIPTION
The CBT6800 provides ten 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 CBT6800 is organized as one 10-bit switch with a single enable
(ON) input. When ON is low, the switch is on and port A is
connected to port B. When ON 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 kresistor.
The CBT6800 is characterized for operation from –40°C to 85°C.
