SN74CBT16212CDL

Overview

The SN74CBT16212CDL is a 5-V, crosspoint/exchange, 24-channel FET bus switch with –2-V undershoot protection. It operates as a 24-bit bus switch or as a 12-bit bus-exchange providing data exchanging between four signal ports. The device features low ON-state resistance (ron) allowing for minimal propagation delay. Operating supply voltage ranges from 4 V to 5.5 V. Maximum on resistance is 12 Ohms. Maximum propagation delay is 150 ps. Minimum operating temperature is -40 C.

Feature Summary
