FEATURES
•
5Ω switch connection between two ports
•
TTL compatible control input levels
•
Designed to be used in 5.5 V to 3.3 V level shifting applications
•
Package options include shrink small outline (SSOP) and thin
shrink small outline (TSSOP)
DESCRIPTION
The CBTD16210 provides 20 bits of high-speed TTL-compatible bus
switching. The low on-state resistance of the switch allows
connections to be made with minimal propagation delay.
A diode to V
CC
is integrated in the circuit to allow for level shifting
between 5 V inputs and 3.3 V outputs.
The device is organized as a dual 10-bit bus switch with separate
output-enable (OE) inputs. It can be used as two 10-bit bus switches
or as one 20-bit bus switch. When OE is low, the associated 10-bit
bus switch is on, and port A is connected to port B. When OE is
high, the switch is open, and a high-impedance state exists between
the ports.
The CBTD16210 is characterized for operation from –40°C 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.

2. This is the increase in supply current for each input that is at the specified TTL voltage level rather than V
CC
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.

NOTES:
1. This parameter is warranted but not production tested. The propagation delay is based on the RC time constant of the typical on-state
resistance of the switch and a load capacitance of 50 pF, when driven by an ideal voltage source (zero output impedance).
