SN74CBT3384A 10-BIT FET BUS SWITCH D 5-Ω Switch Connection Between Two Ports D TTL-Compatible Input Levels description/ordering information The SN74CBT3384A provides ten bits of high-speed TTL-compatible bus switching. The low on-state resistance of the switch allows connections to be made with minimal propagation delay. The device is organized as two 5-bit switches with separate output-enable (OE) inputs. When OE is low, the switch is on, and port A is connected to port B. When OE is high, the.

SN74CBT3384A 10-BIT FET BUS SWITCH D 5-Ω Switch Connection Between Two Ports D TTL-Compatible Input Levels description/ordering information The SN74CBT3384A provides ten bits of high-speed TTL-compatible bus switching. The low on-state resistance of the switch allows connections to be made with minimal propagation delay. The device is organized as two 5-bit switches with separate output-enable (OE) inputs. When OE is low, the switch is on, and port A is connected to port B. When OE is high, the switch is open, and the high-impedance state exists between the two ports.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed. 2.
