10-bit bus switch with precharged outputs
and Schottky undershoot protection for live insertion
FEATURES
CBT6810
DESCRIPTION
• 5 Ω switch connection between port A and port B
• TTL compatible input and output levels
• Undershoot protection included to prevent shoot through level
The CBT6810 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.
changes
• Bias voltage pre-charges the outputs to minimize signal distortion
The CBT6810 is organized as one 10-bit switch with a single 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-kΩ resistor.
during live insertion
• Latch-up protection exceeds 500 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
The CBT6810 is characterized for operation from -40 to +85 °C.

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C.
3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

NOTES:
1. All typical values are at VCC = 5 V, Tamb = 25°C
2. This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND
3. Measured by the voltage drop between the A and the B terminals at the indicated current through the switch. On-state resistance is
determined by the lowest voltage of the two (A or B) terminals.
4. Force IUSP, measure VB ≥ 3 V
