description/ordering informationThe SN74CBT3125C is a high-speed TTL-compatible FET bus switch with low ON-state resistance (ron),
allowing for minimal propagation delay. Active Undershoot-Protection Circuitry on the A and B ports of the
SN74CBT3125C provides protection for undershoot up to −2 V by sensing an undershoot event and ensuring
that the switch remains in the proper OFF state.
The SN74CBT3125C is organized as four 1-bit bus switches with separate output-enable (1OE, 2OE, 3OE,
4OE) inputs. It can be used as four 1-bit bus switches or as one 4-bit bus switch. When OE is low, the associated
1-bit 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 associated 1-bit bus switch is OFF, and the high-impedance state exists between the A
and B ports.
This device is fully specified for partial-power-down applications using Ioff . The Ioff feature ensures that
damaging current will not backflow through the device when it is powered down. The device has isolation during
power off.
