HD74CBT3244 Octal FET Bus Switch ADE-205-643 (Z) Preliminary Rev. 0 August 2001 Description The HD74CBT3244 provides eight bits of high speed TTL-compatible bus switching in a standard '244 device pinout. The low on state resistance of the switch allows connections to be made with minimal propagation delay. The device is organized as two 4-bit low impedance switches with separate output enable (OE) inputs. When OE is low, the switch is on, and data can flow from port A to port B, or vice versa. When OE is high, the switch is open, and the high impedance state exists between the two ports. Features * Standard '244 type pinout. * Minimal propagation delay through the switch. * 5 switch connection between two ports. * TTL-compatible input levels. * Ultra low quiescent power. -Ideally suited for notebook applications.

On-state resistance is determined by the lower voltage of the two (A or B) terminals. 3. This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND.
