Overview

The SN74CBT3244C is a high-speed TTL-compatible FET high-bandwidth bus switch with low on-resistance (ron) to achieve minimum propagation delay. The active undershoot protection circuits on the A and B ports of the SN74CBT3244C provide undershoot protection up to -2V by detecting undershoot events and ensuring that the switch remains in the appropriate off state. The SN74CBT3244C is organized as two 4-bit high-bandwidth bus switches with separate output enable (1OE, 2OE) inputs. It can be used as two 4-bit high-bandwidth bus switches or as one 8-bit high-bandwidth bus switch. When OE is low, the associated 4-bit high-bandwidth bus switch closes, connecting the A port to the B port and allowing bidirectional data flow between the ports. When OE is high, the associated 4-bit high-bandwidth bus switch opens, and there is a high-impedance state between the A and B ports. The device is fully specified for partial power-down applications and uses the Ioff feature. The Ioff feature ensures that no harmful current flows back through the device when the power is off. The device has isolation characteristics when powered off. To ensure a high-impedance state during power-up or power-down, OE should be connected to VCC through a pull-up resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
