Description

The SN74CBTK16245 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 SN74CBTK16245 A and B ports have an active-clamp undershoot-protection circuit. When there is an undershoot, the active-clamp circuit is enabled, and current from VCC is supplied to clamp the output, preventing the pass transistor from turning on.

The SN74CBTK16245 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 a high-impedance state exists between the two ports.

This SN74CBTK16245 device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.

The SN74CBTK16245 is characterized for operation from 40°C to 85 °C.
