DESCRIPTION/ORDERING INFORMATION
The SN74CB3T1G125 is a high-speed TTL-compatible FET bus switch with low ON-state resistance (r
allowing for minimal propagation delay. The device fully supports mixed-mode signal operation on all data I/O
ports by providing voltage translation that tracks V
3.3-V LVTTL, and 2.5-V CMOS switching standards, as well as user-defined switching levels (see
The SN74CB3T1G125 is a 1-bit bus switch with a single ouput-enable (OE) input. When OE is low, the bus
switch is ON, and the A port is connected to the B port, allowing bidirectional data flow between ports. When OE
is high, the bus switch is OFF, and a high-impedance state exists between the A and B ports.
