CBT16212

CBT16212 24-bit bus exchange switch with 12-bit output enables Rev. 02 — 3 November 2008 Product data sheet 1. General description The CBT16212 provides 24 bits of high-speed TTL-compatible bus switching or exchanging. The low ON resistance of the switch allows connections to be made with minimal propagation delay. The CBT16212 operates either as a 24-bit bus switch or as a 12-bit bus exchanger, providing data exchange between four signal ports using the port select inputs (S0, S1 and S2). The CBT16212 is characterized for operation from –40 °C to +85 °C. 2. Features I 5 Ω switch connection between two ports I TTL compatible input levels I ESD protection: N HBM JESD22-A114E Class 1C exceeds 1500 V N CDM JESD22-C101C exceeds 1000 V I Latch-up performance: N JESD78 exceeds 100 mA 3.
