Description
General part information
74CB3T1G125 Series
The SN74CB3T1G125 is a high-speed TTL-compatible FET bus switch with low ON-state resistance (ron), 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 VCC. The SN74CB3T1G125 supports systems using 5-V TTL, 3.3-V LVTTL, and 2.5-V CMOS switching standards, as well as user-defined switching levels.
The SN74CB3T1G125 is a 1-bit bus switch with a single ouput-enable (OE) input. WhenOEis low, the bus switch is ON, and the A port is connected to the B port, allowing bidirectional data flow between ports. WhenOEis high, the bus switch is OFF, and a high-impedance state exists between the A and B ports.
This device is fully specified for partial-power-down applications using Ioff. The Iofffeature ensures that damaging current will not backflow through the device when it is powered down. The device has isolation during power off.
