Texas Instruments Signal Switches, Multiplexers, Decoders 74CBTK16245DGGRE4

The SN74CBTK16245 is a 16-bit FET bus switch designed for high-speed TTL-compatible bus switching. It features a standard ,Äô16245 pinout and provides low on-state resistance, enabling minimal propagation delay during operation. The device includes an active-clamp undershoot-protection circuit that prevents damage from undershoots by clamping outputs to safe levels. It is organized as two 8-bit switches with separate output-enable inputs, allowing for flexible data flow between the A and B ports. The device supports partial-power-down mode through its Ioff feature, which disables outputs to prevent backflow current when powered down. It operates over a temperature range of -40°C to 85°C and is available in multiple package types, including TSSOP and SSOP. The SN74CBTK16245 is suitable for applications requiring reliable bus switching with robust protection features.
