CBTD16210
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
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
or as one 20-bit bus switch. When OE
bus switch is on, and port A is connected to port B. When OE
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.
