The SCDS122A is a bidirectional data transmitter produced by Texas Instruments. It has the characteristics of low voltage difference, low power consumption, low temperature drift and small packaging.
The SN74CBT3125C is a high-speed TTL-compatible FET bus switch featuring four 1-bit switches or one 4-bit switch. It includes active undershoot-protection circuitry on the A and B ports, providing protection for signal undershoot up to -2V by ensuring the switch remains in the proper OFF state during such events.
The device supports bidirectional data flow with near-zero propagation delay and low ON-state resistance (Ron). It is organized as four 1-bit bus switches with separate output-enable inputs. When an enable input is low, the associated switch connects the A port to the B port; when high, a high-impedance state exists between the ports.
| Operating Temperature Range | -40°C to 85°C |
|---|---|
| Undershoot Protection Level | -2 V |
| Number of Switches | Quadruple (4) |
It acts as a high-speed TTL-compatible quadruple FET bus switch with low ON-state resistance.
Active circuitry on the A and B ports senses an undershoot event up to -2V and ensures the switch remains OFF.
